REGIONAL GROUPINGS OF ATLANTIC AND GULF COAST BARRIER ISLANDS

PREFACE

Reconciling the conflicts arising from alternative uses of natural resources is one of the preeminent problems facing the United States now. It is only through cooperation between Federal, regional, State and local agencies, that this problem can be addressed effectively. In the 1960's and early 1970's the Federal government took numerous legislative steps toward promoting such cooperation. The Coastal Zone Management Act is a prime example. In his May 1977 Environmental Message to Congress, President Carter stated "In­ telligent stewardship of the environment on behalf of all Americans is a prime responsibility of government. Con­ gress has in the past carried out its share of this duty well so well, in fact, that the primary need today is not for new comprehensive statutes but for sensitive ad­ ministration and energetic enforcement of the ones we have. Environmental protection is no longer just a legislative job, but one that requires and will now receive firm and unsparing support from the Executive Branch." The scope of this commitment is vast and covers the preservation of wilderness, wildlife, natural and historical resources, and concerns the effects of pollution, toxic chemicals, and potential damage caused by energy resource extraction.

One of the specific problems considered by the Carter administration is the uncontrolled, and often hazardous, development on coastal barrier islands. Within the Department of the Interior a work group was establish­ ed in 1977 to develop an effective plan for protecting the barrier island resource. This group was composed of specialists from various disciplines, agencies, and in­ stitutional levels. With only one year alloted to prepare its plan, the work group utilized existing data bases from the operational programs of participating agen­ cies. The data in this report, which are from the U.S. Geological Survey's nationwide land use and land cover mapping program, represent the USGS contribution to the barrier island study. Thus, this report indicates the commitment of the U.S. Geological Survey to applying earth science information to environmental manage­ ment and problem-solving.

Since data are primarily being presented for analysis, rather than as being analyzed in this report, the text has been kept brief by summarizing why and how the data were prepared, what statistical significance these data have, and finally, by a general discussion of regional pat­ terns. The basic land use and land cover data are compil­ ed in two appendices: the one tabular of area statistics

by individual barrier island; and the other one graphic of sections of the 1972-75, l:250,000-scale USGS open-file land use and land cover maps showing the barrier islands and adjacent coastal land. Using this format, a complete, although generalized, data set on barrier island land use and land cover conditions and trends is presented herein for use in resource and en­ vironmental analysis.

Care should be exercised in the interpretation and use of the land use and land cover area values. Any limita­ tion in the utility of these data results from several fac­ tors characteristic of the photointerpretation and area measurement techniques used. For example, the 1945-55 data were derived from unrectified aerial photographs. Without planimetric control, measure­ ments made from these photographs contain inherent geometric inaccuracies. Similarly, the planimeter technique used in measuring the area of each land use and land cover category may contain a degree of inac­ curacy. Also, there are "selectivity" errors intrinsic to mapping limitations necessarily specified for any land use and land cover classification system. A prime exam­ ple is minimum mapping sizes. Using the criteria applied to Geological Survey maps, a beach 10 miles long and 500 feet wide will not appear on the maps because the USGS rule is that linear features must be at least 660 feet wide in order to be mapped. Similarly, some small residential or commercial areas will go unmapped since the minimum mapping unit for all urban or built-up areas is 10 acres. Thus, a small housing development (15 to 20 houses on 7 or 8 acres) built along the primary dune line would be mapped as beach, and appear in the area summary as part of the barren land acreage.

Several other problems complicated the compilation of the land use and land cover data. The boundary of each barrier island, for example, was not precisely delineated by the Department of the Interior work group. In some cases the barrier islands were actually barrier beaches, with no distinct landward boundary. In such instances arbitrary delineations had to be made by the land use data compilers. Since the photographs used for the 1945-55 data were of lesser optical quality than the 1972-75 data, consistent boundary determinations be­ tween the two time periods, for each barrier island, were often not possible. This frequently resulted in differences in the total area of barrier islands between the two time periods. In many cases these differences were insignificant, but in others they might be quite

VII

significant. It should be recognized, therefore, that a difference in the total area of a barrier island between these two time periods is not necessarily attributable en­ tirely to actual land area change.

Similarly, area differences could result from varia­ tions in tidal conditions between the two periods. It is possible that the 1945 55 photographs were obtained during high tide and the 1972-75 photographs during low tide, or vice versa. Although this may have a small effect on the measured area for most islands, in some cases (where there is a high tidal range or a low beach profile) it may be significant.

Clearly, problems and differences like those stated

above make difficult tfee precise measurement of land use and land cover acreage at two points in time. With all such factors operating simultaneously, the area measurement task is a complex one, and the acreage values obtained are inexact. Nevertheless, the author believes that the percentage values of land in each category reflect the true surface condition.

Several members of the U.S. Geological Survey made substantial contributions to this report. Karen Letke, Robert DeAngelis, Thomas Johnson, and David Wolf compiled and planimetered the 1945-55 land use and land cover maps. George Rosenfield provided the statistical method by which the data were analyzed.

PATTERNS AND TRENDS OF LAND USE AND LAND COVER ON ATLANTIC AND GULF COAST BARRIER ISLANDS

By Harry F. Lins, Jr.

ABSTRACT

Data prepared as part of the U.S. Geological Survey's nationwide land use and land cover mapping program have been applied to a Federal study designed to provide recommendations to the President on methods for protecting undeveloped coastal barrier islands. These land use and land cover data covered two time periods, 1945-55 and 1972-75, and included information on intervening changes. They were used by the Federal study group in an inventory and assessment of developed and undeveloped barrier islands. In addition, state and regional summaries were prepared to facilitate area analysis. Based on the 1972-75 data, several general patterns of land use and land cover were discerned along the Atlantic and Gulf coast barrier islands. Wetlands were found to cover nearly one-half of the total area of all barrier islands. Urban and built-up land, and barren land each occupied almost 14 percent of the total area, while forest land covered about 10 percent. In combination, these four categories accounted for nearly 90 percent of the total 1972-75 barrier island land area. Changes in land use and land cover between 1945-55 and 1972-75 were significant along the entire coastline from Maine to Texas. With the exception of urban or built-up land, all categories of land use and land cover decreased between the two time periods. Urban or built-up land in­ creased by nearly 140,000 acres, while wetlands, the category most af­ fected by this urban growth, declined by almost 80,000 acres.

INTRODUCTION

On May 23, 1977 President Carter presented a broad and comprehensive environmental message to the Con­ gress (Carter, 1977). The President proposed actions to control pollution and protect health, assure environmen­ tally sound energy development, improve the urban en­ vironment, protect natural resources, preserve national heritage, protect wildlife, affirm our concern for the global environment, and improve the implementation of environmental laws. As part of his plan for protecting natural resources the President specifically included coastal barrier islands when he said:

Coastal barrier islands are a fragile buffer between the wetlands and the sea. The 189 barrier islands on the Atlantic and Gulf Coasts are an integral part of an ecosystem which helps protect inland areas from flood waves and hurricanes. Many of them are unstable and not suited for development, yet in the past the federal government has subsidized and insured new construction on them. Eventually, we can expect heavy economic losses from this shortsighted policy.

About 68 coastal barrier islands are still unspoiled. Because I believe these remaining natural islands should be protected from unwise development, I am directing the Secretary of the Interior, in consulta­

tion with the Secretary of Commerce, the Council on Environmental Quality, state and local officials of coastal areas, to develop an effective plan for protecting the islands.

His report should include recommendations for action to achieve this purpose. 1

In following the President's directive, the Secretary of the Interior established the Barrier Island Work Group consisting of representatives from the Heritage Conser­ vation and Recreation Service (HCRS, formerly the Bureau of Outdoor Recreation), the Fish and Wildlife Service (FWS), the National Park Service (NPS), the Office of Coastal Zone Management (OCZM), the Council on Environmental Quality (CEQ), and the Barrier Island Coalition (a consortium of private conservation organizations), with the Heritage Conservation and Recreation Service functioning as lead agency. The Geological Survey was subsequently invited to par­ ticipate by the HCRS through the Secretary of the In­ terior and the Assistant Secretary for Energy and Minerals.

The work group's mandate included the development of protection methods, and recommendations for their implementation. This requred detailed scientific and resource information on each barrier island, in addition to an evaluation of the numerous possible legal forms of protection. The group's first step was to separate those islands which were developed from those undeveloped or unspoiled. The undeveloped islands then had to be separated into protected and unprotected classes. A bar­ rier island classification system was established with Category I, developed; Category II, undeveloped and unprotected; and Category III, protected. This classification system formed the basis for protection planning.

Island categorization (developed versus undeveloped) could most easily be determined by using recent iufor- mation on land use and land cover. The U.S. Geological Survey was asked to provide these data, which were be­ ing compiled as part of its nationwide land use and land cover mapping program. Since the Geological Survey

1 Although the President's message specified 189 barrier islands, the total number of islands included in the resulting study was 282, reflecting broader definitional guidelines established by the work group.

PATTERNS AND TRENDS OF LAND USE AND LAND COVER ON BARRIER ISLANDS

had given priority to the mapping of coastal areas in the preceding three years, nearly all of the Atlantic and Gulf coastal barrier islands had been mapped before the HCRS request.

In addition to providing land use and land cover statistics for the 1972-75 period for use in determining the developed state of barrier islands, an assessment of land use and land cover changes on the barrier islands was also made. The purpose of this absessment was to provide data on the location, types, and magnitude of land use and land cover changes on barrier islands which could be used as a guide for estimating future trends in land use change.

METHODOLOGY

The barrier island land use and land cover area statistics depict land conditions for both 1945-55 and 1972-75, and the attendant changes between these two time periods. These data are presented as Appendix I. Sections of the maps, from which the 1972-75 data were compiled, are presented as Appendix II. The area values of land use and land cover were determined from two series of maps that had been compiled from remotely sensed data.

This study was initiated with land use and land cover information being interpreted from, and mapped direct­ ly on, a series of 1945-55 aerial photographic indices. 2 This interpretation was based on the Level I categories of the USGS classification system designed specifically for use with remotely sensed data (Anderson and others, 1976) (table 1). Area measurements of land use and land cover on each barrier island were then compiled using an electronic digitizer as a planimeter.

A similar technique was then used to compile the statistical data for the 1972-75 period. Maps were not compiled, however, since mapped data were already available for this time period from the Geological Survey's nationwide land use and land cover mapping program. These maps, compiled from remotely sensed data using the Level II categories of the USGS classification system, were similar to the maps of the 1945-55 period. To facilitate comparisons between the two time periods, however, all data were recorded at Level I.

Because of the dissimilarities in the aerial photographs for the two time periods, and the medium to small mapping scales used (approximately 1:63,360 for 1945-55, and 1:250,000 for 1972-75), the accuracy of the Appendix I data varies. This problem is complicated by the 10-acre minimum mapping unit used in compiling both sets of maps. Some land features, such as pocket beaches, wooded parcels, and residential areas are often

2 These data included USGS photo indices (scale 1:62,500 to 1:68,500) and high-altitude black and white photographs (1:30,000 and 1:60,000), Agricultural Stabilization and Conservation Service (ASCS) photo indices (1:63,360) and black and white photographs (1:20,000), Soil Con­ servation Service (SCS) photo indices (1:63,360), and National Ocean Survey (NOS) black and white photographs (1:10,000 and 1:20,000).

DATA DESCRIPTION AND REGIONAL ANALYSIS

In addition to the compilation of area statistics of land use and land cover by individual barrier island, state summaries of these data were also prepared for the Bar­ rier Island Work Group (tables 2-4). The State sum­ maries were useful to the work group in two ways. First,

many State-level agencies provided information in the form of State summaries. Similarly, cooperating Federal agencies supplied data which were aggregated by State. The State summaries of land use and land cover information were, therefore, more easily cor­ related with these other data sets. Second, a major part of the work group's investigation focused on barrier island protection. Since the legal protection of land in­ volves a consideration of ownership that, in turn, often involves State law, it was expedient to have the land use and land cover data summarized by State.

Several distinct patterns of land use and land cover can be quickly discerned from table 3. For example, Florida had the largest barrier island area in 1972-75, with more than one-half million acres. Barrier islands in Florida also had the largest area in urban or built-up land with nearly 102,000 acres. This value represents nearly 20 percent of the total barrier island area within the state and about 6 percent of the total or built-up area

on all barrier islands of the Atlantic and Gulf coasts. New Hampshire, in contrast with Florida, has the smallest barrier island area, just under 1,100 acres, with a little less than 800 acres or 72 percent urbanized. Ur­ ban or built-up land is found on the barrier islands of every state along the Atlantic and Gulf coasts except Mississippi. Its five islands, all located offshore, are only accessible from the mainland by boat. Moreover, The Mississippi islands are in a natural, undeveloped condi­ tion with about 61 percent of their area in wetland, 37 percent in barren land (beaches and dunes), and nearly 2 percent in forest land.

Wetland is the only land use and land cover category consistently found on the barrier islands of every State (table 3). Composing about half of the total barrier island land area, wetland varies from less than 15 percent in Maine to more than 67 percent in Virginia.

Barren land, another ubiquitous category, occupies slightly more area than urban or built-up land (approx-

imately 249,000 acres). Almost all barren land occurs naturally as beaches or dunes. There are, however, some cases where barren land appears as transitional or "fill" areas, and these are characteristically found along the back-bay margins of barrier islands, marking sites of planned urban or built-up development. Such areas are observable in New Jersey, Delaware, Maryland, Virginia, North and South Carolina, and Florida especially on the Gulf coast side.

Land use and land cover changes between 1945-55 and 1972-75 on the barrier islands of Atlantic and Gulf coast states have been diverse, reflecting varying social, economic, and political influences. Certain trends, have been uniform (table 4). Urban or built-up land, for example, has increased on barrier islands in every state except Mississippi, which has no urban land, and usually by dramatic proportions. Florida's urbanized land in­ creased by nearly 70,000 acres, North Carolina's by more than 15,000 acres, and South Carolina's by more

than 11,000 acres; however, Connecticut and New Hampshire's urbanized area increased by only 300 acres each. Most of this increase has been oriented toward recreation and second home development, although in Louisiana a part of the urban trend was commercial and industrial, in support of the development of offshore energy resources.

With the exception of small increases in Rhode Island and Mississippi, wetland area decreased considerably in all states between 1945-55 and 1972-75, for a total loss of 80,000 acres. Barren also decreased, by more than 7,100 but this was not in a uniform pattern. In some states Massachusetts, Connecticut, New York, Delaware, Maryland, Virginia, North Carolina, South Carolina,Georgia, and Texas barren land actually in­ creased primarily as a result of increased transitional land area. Most of these gains, however, were each less than 1,200 acres, although Texas was nearly 1,700, and were readily offset by the sizeable losses in the other

states. Florida, for example, lost more than 14,000 acres of barren land, New Jersey over 1,700, and Alabama more than 1,400 acres.

For regional and environmental analysis of barrier island land use and land cover data, a systematic mor­ phological grouping based primarily on barrier island geological and geomorphological characteristics, and following in part the coastal classification work of Dolan and others (1975) was prepared. Eight regional groups were delineated along the Atlantic and Gulf coasts (fig. 1). Each has a different set of shoreline configurations, composition, and dynamic properties. The land use and land cover data, summarized according to this regionalization, appear in tables 5 to 7. A description of each regional group follows.

Group 1, consisting of 21 New England barrier islands, is located between Sheepscot, Me., and Long

Beach, Mass. (App. II, figs. 8-12). The shoreline characteristics of this coastal region vary from rocky in Maine, to sandy pocket beaches in Massachusetts. The coastline throughout is essentially low-cliffed and com­ posed primarily of older resistant rocks (Putnam and others, 1960). The 1972-75 data show 18 islands of this group with some level of urban development, 13 of them being more than 50 percent urbanized, and 4 of them, Pine Point, Goose Creek, Wells Beach, and Nan- tasket Beach totally, or 100 percent, urbanized.

This high degree of urbanization is influenced by several conditions. First, barrier islands are aethestical- ly desirable for recreation and residence. Although these two societal factors exert considerable develop­ ment pressure on all barrier islands, that pressure is strongly felt in the New England group where all 21 islands total a relatively small 14,769 acres. The size

becomes even more critical when the area is further influenced by proximity to large coastal cities. Most of these Group 1 barrier islands are located near Bath, Portland, Portsmouth, and Boston, and are linked to these cities by a good transportation network. Finally, the relatively stable geomorphological nature of these

islands enhances their suitability for development, thereby attracting people who might otherwise choose to build in safer areas.

Approximately 43 percent, or nearly 6,300 acres, of the total New England group area is urban or built-up land (table 6). Wetland accounts for 30 percent or nearly

4,500 acres of the group area, barren land 22 percent or a little more than 3,200 acres (primarily beaches), and forest land 5 percent or nearly 800 acres. Between 1945-55 and 1972-75 the predominant land use and land cover trend on the New England barrier islands was toward an increase in urban land of 47 percent, or a little over 2,000 acres. This urbanization was primarily at the expense of wetland, which diminished by 21 percent or nearly 1,200 acres.

(App. II, figs. 12-27), this group is a remnant of Pleistocene glacia- tion, composed of glacial and fluvioglacial deposits (King and Beikman, 1974). The coastal zone adjacent to the New York Bight is hilly, with moderate local relief and

gentle slopes. The barrier island shorelines are primarily of sandy beach form, although some are characterized by pocket beaches (Putnam and others, 1960). With a total area of nearly 64,000 acres in the 40 islands, 24 evidence some urban development, 9 are more than 50 percent urbanized, and 2 Madaket and North Haven are totally urbanized.

Although the Group 2 islands had over 17,000 acres of urban or built-up land in 1972-75 (nearly three times that in Group 1; see table 6), this acreage corresponded to 27 percent of the total group area, much less than the 43 percent value in Group 1. One reason for this is that several of the Group 2 islands are physically isolated so access is limited. Muskeget, Nashawena, Cuttyhunk, and Block Islands, as well as parts of Martha's Vineyard and Nantucket, are good examples. Another reason is

that several islands, including Eastham, Nauset, and Monomoy, are protected as national seashores, national wildlife refuges, or state parks. In 1972-75, besides the 17,000 acres in urban or built-up land, the New York Bight islands had approximately 22,000 acres in barren land (primarily beaches), 14,000 acres in wetland, 6,000 acres in rangeland (vegetated dunes), and 2,200 acres in forest land.

Land use and land cover change on these islands was minimal between 1945-55 and 1972-75, except in the ur­ ban or built-up category where there was a 39 percent or 6,700-acre increase. Contributing to this were cor­ responding decreases in forest land (900 acres), rangeland (300 acres), and wetland (300 acres). In­ terestingly, the total Group 2 area increased by nearly 6,000 acres. Such a large increase in total area is difficult to explain with certainty since it is unlikely that filling operations accounted for so much additional land area. It is more probable that part of this measured change is erroneous, and is the cumulative effect of smaller inaccuracies in interpretation and measure­ ment. Of the changes in total group area, between 1945-55 and 1972-75, Group 2 with 10 percent had the largest percentage area change for all eight groups. Most of the other changes fell within four percent, a range almost entirely attributable to error in interpreta­ tion and to mensuration technique. The statistical significance of measured changes is discussed later in the report.

Continuing south along the coast, from Sandy Hook, N.J. to North Island, S.C., are the Group 3 or Mid-

Atlantic barrier islands (App. II, figs. 28-52). This entire group forms a part of the seaward edge of the continent's eastern coastal plain. These islands are characterized by broad sandy beaches, and are primarily composed of Pleistocene marine sediments (Dolan, 1970; King and Beikman, 1974). There are 53 barrier islands in the Mid-Atlantic group, with a total area of over 300,000 acres. Of the 53 islands, 35 contain some urban development. Only 6 however, Sandy Hook, Barnegat, Long Beach, Atlantic City, Ocean City, and Fenwick South, are more than 50 percent urbanized, and none are totally urbanized.

Wetland vegetation is the predominant land cover type throughout this group with nearly 159,000 acres, or just over half the total group area. Wetlands form a nearly continuous strip along the back-bay side of these barrier islands. The next major area, with over 73,000 acres or 24 percent in barren land, is primarily ocean- front beach and dunes. Urban or built-up land is third in extent with 52,000 acres or 17 percent. Most of this con­ sists of resort cities, such as Wildwood, Rehoboth, Bethany, and Ocean City. These areas are characterized by extensive commercial sectors (hotels, motels, and restaurants) and large seasonal population fluctuations. There are, however, some permanent urbanized com­ munities in Group 3 that maintain a more stable popula­ tion and economy throughout the year. The New Jersey coastline between Atlantic City and Ocean City is the best example. Urban development on these Mid-Atlantic barrier islands has typically located along the primary dune line, and extended back through the adjacent

DATA DESCRIPTION AND REGIONAL ANALYSIS

grassland zone. In highly developed areas, building has continued even farther back-island, into the marshlands bordering the back-bays.

Between 1945-55 and 1972-75 the most significant changes occurring on the Mid-Atlantic islands were in the urban or built-up and wetland categories. As with Group 2, the largest change occurred in the area of ur­ ban land, which doubled, increasing by nearly 26,000 acres. Most of this urban expansion was into wetlands, which decreased by nearly 21,000 acres or 12 percent.

Group 4, the Sea Islands, extends from South Island, S.C. to Cumberland Island, Ga. (App. II, figs. 53-62). These 44 islands are also a part of the eastern coastal plain but, unlike their Mid-Atlantic counterparts, are primarily composed of Holocene, not Pleistocene, sediments (King and Beikman, 1974). They are further differentiated from the Group 3 islands by their physical structure. While the Mid-Atlantic islands are primarily a system of elongated sandy beaches, the Sea Islands ex­ hibit no such elongated, interconnecting beach characteristic. These islands stand more as individual outliers of a broad wetland-estuarine system.

Group 4 has a total area of 312,000 acres: of its 44 islands, only 15 have any urban development, and only one, Sullivans, is more than 50 percent urbanized. The Sea Islands are largely dominated by wetland vegeta­ tion which totals over 194,000 acres, or more than 60 percent of their total area. Forest land also occupies a relatively large area with over 66,000 acres. Urban or built-up land, on the other hand, constitutes less than 7 percent of the total area with just under 20,000 acres. Even so, there has been a threefold or 13,000 acre in­ crease in urban land use between 1945-55 and 1972-75. Accompanying this urban area increase were corre­ sponding decreases in the area of agricultural land by over 4,000 acres (-39 percent), and in wetland by over 9,000 acres (-5 percent).

Group 5, the Florida Atlantic barrier islands, begins at Amelia Island and continues to Key Biscayne (App. II, figs. 63-77). The first 12 of its 22 islands, including Hut- chinson Island,are composed of Holocene materials, and the remaining 10, from Jupiter Island south, of Pleistocene materials (King and Beikman, 1974). All these islands are more like those in Group 3, and less like those in Group 4, in that they form an elongated beach continuum rather than a series of dissected islands.

Based on the 1972-75 data, 21 of these 22 islands show some urban development. Of these, 11 are more than 50 percent urbanized, and 1 (Hillsboro Beach) is totally urbanized. Out of a total area of about 150,000 acres, almost 70,000 acres are in urban or built-up land. The second largest category is wetland, comprising nearly 40,000 acres or 26 percent of the total area. Forest land occupies about 27,000 acres, or roughly 18 percent of the Group 5 area, while barren land covers nearly 11,000 acres or just over 7 percent of the total.

Between 1945-55 and 1972-75 changes on the Florida Atlantic barrier islands were extensive. As in the Group 4 islands, urban or built-up land, for example, sustained a threefold increase, corresponding in this case to over 47,000 acres. Balancing this urban increase were marked decreases in several other land use and land cover categories. Forest land was most affected, losing over 18,000 acres (-41 percent). Wetland area decreas­ ed by more than 14,000 acres (-27 percent), and barren land lost over 10,000 acres (-49 percent).

Immediately adjacent to the Florida Atlantic barrier islands, on the south side, are the Florida Keys. Geologically, the Keys form a break in the chain of Atlantic and Gulf coast barrier islands. Whereas Florida's barrier islands are formed of sand, the Florida Keys are formed of limestone. As a result of this mor­ phological distinction, and since the Florida Keys are a relatively small proportion of all barrier islands, the Bar­ rier Island work group elected not to include these in its study.

The Group 6 or Eastern Gulf Coast barrier islands, form a chain northwestward from the Keys along the Gulf of Mexico, beginning at Cape Sable, Fla., and con­ tinuing to Cat Island, Miss., (App. II, figs. 78-104). This group includes 68 islands of varying geological composi­ tion. Most of the Florida barrier islands are composed of either Eocene, Miocene, or Pleistocene sediments. However, all the Alabama and Mississippi islands are composed of Holocene materials (King and Beikman, 1974), and many are backed by extensive marshlands.

As a group, the Eastern Gulf Coast barrier islands are much less developed than the Florida Atlantic islands. Of the 68, only 39 or 57 percent have some urban development, and of these only 12 islands (18 percent) are more than 50 percent urbanized. None are totally ur­ banized. Based on the 1972-75 data, the Group 6 islands have a total area of over 406,000 acres. Wetland, the largest area, amounts to more than 217,000 acres or 54 percent of the total. Water bodies, primarily as em- bayments, form the next largest area with nearly 76,000 acres (19 percent), while barren land, forest land, and urban or built-up land all total approximately 36,000 acres or roughly 9 percent each.

Between 1945-55 and 1972-75, the greatest change on the Group 6 islands occurred in urban or built-up land, which increased by slightly more than 28,000 acres. This considerable gain (302 percent) coincided with losses of 12 percent in wetland (29,000 acres), of 3 percent in water bodies (-2,600 acres), and 13 percent in barren lands (-5,400 acres). There were also gains of 436 percent in rangeland ( + 2,600 acres), and of 27 per­ cent in forest land ( + 7,800 acres).

Farther to the west in the Gulf of Mexico, stretching from the Chandeleur Islands to Isle Dernieres, are the Louisiana, or Group 7, barrier islands (App. II, figs. 105-112). Totaling nearly 39,000 acres, this entire

10 PATTERNS AND TRENDS OF LAND USE AND LAND COVER ON BARRIER ISLANDS

group is composed of fine-grained deltaic deposits of Holocene age from the Mississippi River (Dolan, 1970; King and Beikman, 1974). Of these 18 islands, only Grand Isle is linked to the mainland by road. Most of the others form the leading edge of an isolated and segmented wetland-estuarine system.

Only 8 of the Louisiana islands contain any urban development and all of those are less than half urban­ ized. Grand Isle is the most extensively developed, with 48 percent of its area or 1,900 acres in urban or built-up land. The major portion of the group's land area consists of 24,000 acres in wetlands, or 62 percent of the total area. Urban or built-up land is next in extent with just over 6,700 acres or 18 percent. A large part of this usage is related to the oifshore oil and natural gas industry, with a comparatively small part devoted to residential or recreational land. Barren land occupies roughly the same area as urban or built-up land, just over 6,200 acres.

The basic pattern of land use and land cover change on the Louisiana barrier islands is typical of most other groups between 1945-55 and 1972-75. Urban or built-up land area has increased, while wetland area has de­ creased. The magnitude of change was, however, greater in Louisiana than in most other island groups. For example, in the Louisiana group with less than 39,000 total acres, the urban or built-up land area in­ creased by more than 5,000 acres. Whereas in 1945-55 urban or built-up land accounted for 4.5 percent of the total Group 7 area, by 1972-75 this figure had soared to 17.5 percent, an increase of 13 percentage points. Within most other barrier island groups, the percentage of urban or built-up land increased by only 3 to 9 points during the same period. The development of Louisiana's offshore petroleum industry is the primary reason for this difference.

The Texas barrier island group, the eighth and final in this regional stratification, ranges from Bolivar Penin­ sula to Brazos Island, Texas (App. II, figs. 113-125). Much of the backing coastal zone is composed of Pleistocene materials, although the islands themselves are almost entirely composed of Holocene deposits (King and Beikman, 1974). Their physical appearance is similar to the Mid-Atlantic barrier islands, with an inter­ connecting system of elongated sandy beaches backed by an extensive wetland-estuarine system.

Of the eight island groups, Texas has the second largest total area with nearly 384,000 acres. Also, with 16 it has the fewest number of islands, making them some of the largest along the Atlantic and Gulf coasts. Of these 16 islands, 11 contain some urban or built-up land. None, however, are more than 50 percent urbaniz­ ed. Galveston Island is the most extensively developed, with 33 percent of its land area in an urban condition. To put this value in perspective, however, although only one-third of the area, it corresponds to nearly 10,000 acres, giving Galveston one of the largest proportions in

urban or built-up land of all 282 barrier islands. In Group 8, as with most other groups, the largest individual land use and land cover category is wetland, with about 186,000 acres or 49 percent of the total area. This is followed by more than 85,000 acres in rangeland (22 per­ cent), 82,000 acres in barren land (21 percent), and slightly less than 20,000 acres in urban or built-up land (5 percent).

Despite the diversity of land use and land cover types in Group 8, land use and land cover changes between 1945-55 and 1972-75 were dominated by 2 categories, urban or built-up land and rangeland. Urban or built-up land more than doubled during this period, increasing by over 10,000 acres. Rangeland, on the other hand, decreased in area by nearly 4,000 acres.

STATISTICAL SIGNIFICANCE

At the beginning of the data compilation process it was recognized that inherent error factors exist in pho- tointerpretation, area measurement, and change men­ suration procedures. Although some assumptions can be made in assessing the accuracy of a given data set based on consistency factors of interpreters and equipment, these assumptions cannot be applied to all compilation variables. Thus, to validate assessments of land use and land cover changes for the barrier islands, this in­ vestigator needed to know if the values of change, as measured by a planimeter, were real, or part of the in­ herent error involved in the mapping and measuring technique. A particular concern was with the statistical significance of the change values that resulted from mapping work done at two different times, with different types of photography, and at several different scales.

To determine the amount of change which could be at­ tributable to procedural "noise" versus real change, a statistical technique was designed and applied to the land use and land cover change data. Based on the stan­ dard error factor for mapping at various scales, and the areas of measured categories, the expected value of area change that is, the change resulting from inherent technique errors was calculated. A test of the null hypothesis, which assumes the change in area to be due to measurement error, was then employed to determine whether or not the indicated change was caused by error in measurement alone. If the null hypothesis was re­ jected (indicating that the change in area was probably real) then an alternative hypothesis, which assumes the change in area to be real, was tested. The alternative hypothesis was evaluated at the 95 percent level of confidence using the Student's t-statistic. Acceptance of the alternative hypothesis indicates that the change in land use area was real. The results of this evaluation are presented in table 8.

As table 8 shows, it is possible to discern several significant statistical characteristics in the study's land

use and land cover change data. For example, in all 8 of the barrier island regional groups, the measured change in urban or built-up land area was determined to be statistically significant at the 95 percent level of confidence. This determination indicates that most of the area change measured was real, that is, not at­ tributable to inherent measurement error. The relative­ ly large increases in each region's urban or built-up area, which ranged from about 2,000 acres in the New England group to about 47,000 acres in the Florida Atlantic group, accounted for the statistical determina­ tion that the changes were real rather than inherently erroneous.

In contrast to this condition, area changes in agricultural land were not as statistically significant. Of the 8 island groups, only 5 contained any agricultural land New York Bight, Mid-Atlantic, Sea Islands, Florida Atlantic, and Texas. Of these, the Sea Islands and the Florida groups were the only 2 with statistically significant area changes between 1945-55 and 1972-75. In both cases, moreover, the area of change was sizeable. The Sea Islands agricultural area dropped from about 10,900 acres to 6,600 acres, for a 4,300-acre loss during the 25-year period. In the same period, the same land use in the Florida Atlantic islands dropped from 3,100 acres to 2,300 acres, for an 800-acre loss. Com­ paratively, agricultural land area changes in the other 3 island groups were small, amounting to about 20 acres, 40 acres, and 250 acres respectively for the islands of Texas, New York Bight, and Mid-Atlantic, which ac­ counted for the acceptance of the null hypothesis for these groups.

CONCLUSIONS

Land use and land cover patterns on barrier islands vary widely in response to geographically diverse natural, cultural, and economic conditions. There are, however, several general patterns which prevail over most of the Atlantic and Gulf coast islands. For exam­ ple, wetland and barren land (primarily beaches and

dunes) are naturally dominant cover conditions and are often accompanied by sizeable areas of forest land. Of the nearly 1.7 million acres making up the 282 barrier islands, wetland covers roughly half or 840,000 acres. Barren land occupies another 15 percent or 250,000 acres, while forest land covers slightly less than 10 per­ cent or over 150,000 acres. The area of urban or built-up land is slightly less than the area of barren land, which means that four categories wetland, urban or built-up land, barren land, and forest land account for nearly 90 percent of the total 2,600-square mile area of Atlantic and Gulf Coast barrier islands.

From a regional perspective, the most developed bar­ rier islands are those in the Florida Atlantic group. Not only do these Group 5 islands have the largest total ur­ banized acreage, nearly 70,000 acres, but they also have, with more than 46 percent, the largest proportion of ur­ ban or built-up area of any group. Identification of the least developed group among the barrier islands depends on the criteria used to determine extent or degree of development. For example, with about 6,300 acres, the New England group has the smallest urban or built-up area. Accounting for nearly 43 percent of the Group 1 land area, however, this value represents the second largest urban area percentage among all the groups. New England also has the smallest total area among the 8 groups. The Texas group, on the other hand, has over 19,000 urbanized acres (more than three times that in New England), yet maintains the smallest urbanized percent of total area at just over 5 percent. Texas has the second largest total group area with over 380,000 acres.

The most significant aspect of barrier island land use and land cover patterns relates to recent changes. Dur­ ing the intervening period from 1945-55 to 1972-75, all categories of land use and land cover decreased except urban or built-up land, which increased by 138,000 acres. Wetlands were most affected by this urban development, losing nearly 80,000 acres. Forest land lost about 16,000 acres, while barren land decreased by 7,000. The most significant regional changes occurred on the Group 5 Florida Atlantic barrier islands where ur­ ban or built-up land increased by over 47,000 acres, while forest land, wetland, barren land, and agricultural land all decreased by about 20,000, 15,000 10,000, and 1,000 acres respectively. The Group 6 Eastern Gulf Coast barrier islands also sustained significant changes during the 1945-55 to 1972-75 period. Urbanized land increased by more than 28,000 acres and forest land in­ creased by nearly 8,000 acres, while wetlands were reduced by 30,000 acres and barren land lost over 5,000 acres. Although the two Florida groups appear to have undergone some of the largest changes recently, the land use and land cover data presented in this report in­ dicate that barrier islands from Maine to Texas have ex­ perienced substantial increases in urban land use since World War II.
