NATIONAL LIST OF PLANT SPECIES THAT OCCUR IN WETLANDS %

REGION 6 - SOUTHERN PLAINS

p

-The following is a subset of the National List of Plant Species That

Occur In Wetlands of the southern plains region of the United States. This

area includes Oklahoma and Texas.

The list was initiated by the US Fish and Wildlife Service, National Wet-

land Inventory (NWI). A candidate national list of more than 5000 species was

developed and, using information from more than 250 taxonomic references, the

NWI assigned a tentative wetland indicator status to many of the species. The

indicator status categories, which define the estimated probability of a spe-

cies occurring in wetlands, are as follows:

Category Symbol Definition

OBLIGATE WETLAND OBL Plants that occur almost alwaysPLANTS (estimated probability >.99%) in

wetlands undernatural conditions.

FACULTATIVE WETLAND FACW Plants that occur usually (estimatedPLANTS probability >67 to 99%) in wetlands,

but also occur (estimated probability

1% to 33%) in nonwetlands.

FACLTATIVE PLANTS FAC Plants with a similar likelihood(estimated probabilit-" 33% to 67%) ofoccurring in both wet'ands andnonwetlands.

FACULTATIVE UPLAND FACU Plants that occur sometimes (estimatedPLANTS probability 1% to 33%) in wetlands,

but occur more often (estimatedprobability >67% to 9Q7) innonwetlands.

OBLIGATE UPLAND UPL Plants that occur rarely (estimatedPLANTS probability

comprised of representatives from the Fish and Wildlife Service, Environmental

% %" Protection Agency, Soil Conservation Service, and Corps of Engineers. The

national panel developed guidelines for the review process and established

regional panels composed of a representative from each agency. The regional

panels reviewed the plant list for their region and provided the national

review panel with the results. The list that follows represents a subset of

the reviewed list for Region 2. Note: Although additional work by the

regional panel will be required, the current status of the list is considered

to be adequate for use in this manual. The list will be updated as further

revisions are made.

Nomenclature used in the list is based on the National List of Scientific

Plant Names (USDA-SCS 1982). The generic name is listed only once, and

species within a genus are alphabetized.

Symbols

Symbols appearing in the list under the indicator status column are as

follows:

+: A "+" sign following an indicator status denotes that the species

generally has a greater estimated probability of occurring in

wetlands than species having the general indicator status, but a

lesser estimated probability of occurring in wetlards than those

having the next highest general indicator. For exa-ple, a species

with an indicator status of FAC+ occurs in wetlands more often than a

species designated as FAC, but less often than a species having a

FACW status.

A "-" sign following an indicator status (e.g. FACW-) denotes that

the species generally has a lesser estimated probability of occurring

in wetlands than species having the general indicator status, but

a greater estimated probability of occurring in wetlands than those

having the next lowest general indicator. For example, a species

with an indicator status of FACW- occurs in wetlands less often than

a species with a FACW status, but more often than a species having a

FAC- status.

DRA: This symbol indicates that the species normally occurs at the

indicated estimated probability in wetlands, but only durin2 pericds

when standing water is absent.

3

' t.

TV- -..

?: A "?" indicates that the species was reviewed by the regional panel,

but no decision has been made regarding the appropriate indicator

status.

-: A dash without an associated indicator status signifies that no

review comments were received, usually because the species is rare in

the region or its taxonomic status is questioned.

An X prior to the species name in the scientific name column denotes a hybrid.

For purposes of this manual, all species appearing on the regional plant list

as FAC-, FACU+, FACU, or FACU- have been deleted from the list because they do

not contribute toward hydrophyttc vegetation.

Region 6 - Southern Plains '..

1. Following is a list of plant species that commonly occur as dominant

species in wetlands of the southern plains of the United States. This region

includes Texas and Oklahoma.

2. The list is a subset of the list provided in Section 1. Only species

that commonly occur as dominant species in wetland types of the region are

listed. All included species have an indicator status (see Section I for

definitions of indicator status categories) of OBL, FACW, or FAC.* These

species are considered to e typically adapted for life in anaerobic soil con-

ditions. Thus, the vegetation parameter is satisfied when more than 50 per-

cent of the dominant species in a community type appear on this list. In such

cases, it is unnecessary to use the list provided in Section 1. However, many

other species listed in Section 1 as OBL, FACW, or FAC may be dominant at a

given location. Therefore, use the list provided in Section 1 when more than

50 percent of the dominant species in a community type are not included in

Section 2. CAUTION: THIS LIST IS NOT INTENDED TO INCLUDE ALL OF THE SPECIES

THE' REG.ON THAT ARE TYPICALLY ADAPTED FOR IFE IN ANAEROBIC SOIL Na...

3. In some cases, only the generic name is listed. When only one indi-

cator status is shown for a genus, all species of the genus that are listed in

Section I have the designated indicator status. When a range of indicator

statuses is shown (e.g., OBL-FAC), the species listed in Section I have dif-

ferent indicator statuses. However, it is unnecessary to consult Section I

when the range consists only of OBL, FACW, and/or FAC since a species having

any of these indicator statuses is considered to be typically adapted for

life in anaerobic soil conditions. When the indicator status range of the

genus includes FAC- or FACU, identify the species and consult Section I to

determine the indicator status for that species. Species having a "7" in the

indicator status column are thought to commonly occur in wetlands of the

region, but no indicator status has been assigned to these species.

4. Scientific nomenclature follows that provided in Section 1. Common

names sometimes vary from those provided in Section I because a species may

have two or more common names. The indicator status for a given species is

the same on both lists.

• No species having an indicator status of FAC- are included. " '
