General Summary Camp Robogi and Area is a large, linear rural natural area that consists of the remnants of natural vegetation that has been left along the Credit River west valley wall and floodplain, for two thirds of the distance between the villages of Huttonville and Norval. The tableland above the valley is in agricultural use and some portions of the floodplain are or have been used for agriculture now or in the past. The floodplain is more extensive and more accessible on the west side of the river, and as such shows more disturbances from agricultural and recreational use. In spite of the fragmentation from land uses and other disturbances, this area is of good quality, containing provincially significant wetlands, rare vegetation community inclusions, and supports Species At Risk and rare species. There are numerous seepage areas along the valley walls which provide some uncommon habitat niches. An Ecological Land Classification vegetation community inventory was conducted over the 23% of this area that the field crew had access to. A thorough inventory of the plant species was conducted in conjunction with the ELC work (Table 1). Fish species presence was taken from sampling conducted by CVC from 1992 to 2010.

Physical Features The Camp Robogi and Area is in the Peel Plain physiographic region (Chapman and Putnam, 1984), characterized by a relatively flat topography which gradually slopes toward Lake Ontario containing numerous rivers and streams with deeply cut valleys. The soils are predominantly clay due to a thin layer of lacustrine clay and silt being deposited over the underlying till. The till contains a high proportion of shale, which has been derived from the dominant bedrock in the region. The clay soils and till have low permeability leading to a slow infiltration rate in the area. Most of the soil in this natural area is sandy loam although there are bands of variable soils, suggesting a historically different drainage pattern. Coarser rock fragments and gravel occurs at approximately 50 cm depths. One of the wetland communities here has organic soil. This natural area is contained in the Credit River valley and includes the valley walls and floodplain on the southwest side of the river. The river borders this natural area along the north and northeast side. The river here takes a winding course across the floodplain, and a few short intermittent streams drain the adjacent tablelands above the valley, directly into the Credit River. Human History The Camp Robogi and Area natural area is located within the City of Brampton and the Town of Halton Hills, beginning at Hertiage Road, upstream of the Village of Huttonville and extending through the community of Norval in Halton Hills. The first European settlers in Norval arrived in the early 1820’s, built grist and saw mills and raised livestock (sheep) east of the mill site (village) and valley (Esquesing Historical Society, 2012a). White Oak (Quercus alba) and White Pine (Pinus strobus), plentiful in the original forests of the area were cut as a staple of the local forest industry. The oak wood was turned into barrel staves which were floated down the river and shipped to the Caribbean to make rum barrels. The tall straight White Pine trunks were used as ship masts by the British Navy (Esquesing Historical Society, 2012b). Other species of the local forests fed the saw mill that produced building materials and planks for the plank road (now Highway 7) stretching between York and Guelph that was completed in 1851. Norval was a major stagecoach stop along the plank road (Anonymous, 2012) and developed into an important community with a variety of businesses including woolen and flax mills that were supported by local agriculture, a broom factory, a brass foundry, a cooperage and a Mechanic’s Institute (Anonymous, 2012; Esquesing Historical Society, 2012b). Inscriptions (written in 1994) on the backs of photographs of Norval from 1920, describe large maple, chestnut, walnut and butternut trees along the plank road route and remark that the Credit River was much wider and deeper at Norval then than it is now (Esquesing Historical Society, 2012b). In the late 1950s the Brampton Rotary Club purchased 28 acres of agricultural land and created Camp Robogi that was used as a summer camp for underprivileged children. Robogi stood for Rotary boys and girls (Slater, 2012). Camp Robogi passed into City of Brampton ownership in 1983. This natural area includes part of the City-owned Camp Robogi property on the west side of the Credit River. This property does not have public access and as such receives little recreational pressure or disturbance. Agriculture currently dominates the surrounding area, with abundant farms and fruit orchards. A few non-agricultural residences lie adjacent to the west side of the natural area, along Winston Churchill Blvd. Another large natural area lies across the river: Heritage – Bovaird City Wide Park (NAI #1325, 5225). The Credit River valley through Norval is within the Greenbelt, and approximately 200 hectares of lands located north of the Credit River and east of Winston Churchill Boulevard are located within the Greenbelt Plan as Protected Countryside – Natural Heritage System in the City of Brampton.

Vegetation Communities The MNR Ecoregion boundary is drawn through this natural area. The north part of the natural area is in the Lake Simcoe – Rideau Ecoregion (6E) and the south part of the natural area is in the Carolinian Forest Ecoregion (Lake Erie – Lake Ontario Ecoregion; 7E). The general community types present here are coniferous forest (7%), deciduous forest (11%), mixed forest (36%), marsh (4%), deciduous swamp (9%), open aquatic (<1%), cultural meadow (7%), cultural thicket (1%), cultural savannah (10%), cultural woodland (10%) and plantation (4%). A total of eight vegetation communities were mapped for the 23% of this natural area that was accessed, representing eight different vegetation types (Table 2). One of these communities, the Dry-Fresh Black Locust Deciduous Forest (FOD 4-C) includes patches of Dry-Fresh Hickory Deciduous Forest (FOD2-3) and Native Forb Old Field Meadow (CUM1-A), which were too small to be mapped and classified as separate polygons. The Hickory forest inclusion is a regionally rare vegetation type and an abundant producer of mast (nuts), serving as an important high quality food source for a variety of wildlife species. Five other communities also have small inclusions that are too small to be mapped as separate communities but provide important additional habitat diversity at Camp Robogi and area. The Exotic Cultural Woodland (CUW1-B) contains inclusions of Jewelweed Organic Meadow Marsh (MAM3-8), Swamp Maple Mineral Deciduous Swamp (SWD3-3) and Native Forb Old Field Meadow (CUM1-A) patches. The Native Forb Old Field Meadow community (polygon #1026065) includes a Buckthorn Cultural Thicket (CUT1-B) patch. The Dry-Fresh Sugar Maple – Hardwood Deciduous Forest community includes patches of Fresh-Moist Manitoba Maple Lowland Deciduous Forest (FOD7-A) and Red Pine Coniferous Plantation (CUP3-1). The White Cedar – Hardwood Organic Mixed Swamp (SWM4-1) community contains inclusions of Jewelweed Organic Meadow Marsh (MAM3-8), Swamp Maple Mineral Deciduous Swamp (SWD3-3) and Native Forb Old Field Meadow (CUM1-A) patches. The Hawthorn Deciduous Shrub Thicket community contains inclusions of Dry-Fresh Old Field Meadow (CUM1-1) and White Pine Coniferous Plantation (CUP3-2) patches. The Dry-Fresh Sugar Maple – Hardwood Deciduous Forest community is mature. It also contains numerous seepage areas.

Species Presence Vascular Plants A total of 227 vascular plant species occur in this natural area, of which 158 (70%) are native. One of these is a Species At Risk. Butternut (Juglans cinerea) is Endangered both nationally and provincially (Table 3). Butternut is also provincially rare (S-rank S3?). Eight additional plant species are regionally rare (Table 4). At Camp Robogi and Area, there is one planted species, Rice Cutgrass (Leersia oryzoides). Of the 69 non-native plant species found here, 39 are included on the CVC Priority Invasive Plants list. Nine of these species are considered to be transformers which exclude all other species and dominate sites indefinitely, six species are highly invasive which tend to dominate only certain niches or do not spread rapidly from major concentrations, eleven species are moderately invasive which can become locally dominant given certain conditions and eleven species are minimally invasive which do not pose an immediate threat to natural areas but compete with more desirable native species. Two of the non-native species here are considered potentially invasive. Birds A total of 28 bird species were observed at Camp Robogi and Area, all of which are native. Two of these are Species At Risk. Canada Warbler (Cardellina canadensis) is Threatened nationally and considered Special Concern provincially and Eastern Wood-peewee (Contopus virens) is considered Special Concern nationally (Table 3)

This natural area supports one species of area-sensitive forest interior bird, Hairy Woodpecker (Picoides villosus), one species of grassland bird, Eastern Kingbird (Tyrannus tyrannus), and one species of raptor, Osprey (Pandion haliaetus). Fish Twenty-two fish species occur in the main Credit River and tributary streams of this natural area, of which 20 (91%) are native. One of these, Atlantic Salmon (Salmo salar) is a Species At Risk, was extirpated but has been re-introduced (Table 3). An additional species, Rock Bass (Ambloplites rupestris) was recorded as a historical record from sampling in 1982. The Central Mudminnow (Umbra limi) is considered uncommon in Brampton (J. Clayton, pers. comm. 2012) and is associated with groundwater discharge. Another species present here, Johnny Darter (Etheostoma nigrum) is considered to be relatively uncommon in the Credit River watershed and Brampton (J. Clayton, pers. comm., 2012) and is only present in larger streams. In this area, the Credit River supports a mixed cool/coldwater fish community. Many of the species present are tolerant of warmer waters and low dissolved oxygen, but several of the species present here, including Fantail Darter (Etheostoma flabellare), Northern Hog Sucker (Hypentelium nigricans), Rainbow Darter (Etheostoma caeruleum), Atlantic Salmon and Brown Trout (Salmo trutta) are indicators of mixed cool/cold water or coldwater conditions. Smallmouth Bass (Micropterus dolomieu) is a top predator and is an indicator of large order, warmwater streams and rivers. Longnose Dace (Rhinichthys cataractae) requires high dissolved oxygen conditions. Several species, including Northern Hog Sucker, Johnny Darter and Hornyhead Chub (Nocomis biguttatus) are typical of large river systems. One of the species present here, River Chub (Nocomis micropogon) only occurs in the lower part of the Credit River and is associated with access to Lake Ontario. Sea Lamprey (Petromyzon marinus) is a significant threat to salmonids and the presence of this species in the Credit River system is controlled by barriers/dams and by lampricide applications. Atlantic Salmon, Brown Trout and Smallmouth Bass are of recreational interest. Atlantic Salmon is migratory, travelling up the Credit River to spawn. Butterflies and Skippers Two butterfly species were observed at Camp Robogi and Area. One is a Species At Risk. Monarch (Danaus plexippus) is designated Special Concern both nationally and provincially and is also provincially rare (S-rank S2N, S4B; Table 3). Dragonflies and Damselflies One native damselfly species was observed in this site. Herpetofauna Three common amphibian species were encountered at this site. All three of these species are native. Mammals Two native mammal species were observed in this site. Both species, Eastern Gray Squirrel (Sciurus carolinensis) and White-tailed Deer (Odocoileus virginianus), forage and shelter in treed communities. Retaining intact mature and regenerating forests is essential to ensure these species have the habitat necessary for them to survive in urban environments. Table 3. Designated Species At Risk

The valley slope communities tend to be somewhat less impacted, with occasional widespread exotic species, than valley bottom communities (with indicators of past agricultural use) which have abundant and widespread invasive species. Common Buckthorn (Rhamnus cathartica) infests all of the communities in this area at a moderate level and Garlic Mustard (Alliaria petiolata) is also a moderate disturbance in most communities here. One of the forest communities (polygon 1026070) is dominated by Black Locust (Robinia pseudo-acacia). Creeping Jennie (Lysimachia nummularia) creates a heavy disturbance in one of the forest communities (polygon 1026069), a moderate disturbance in the mixed swamp community (polygon 1026068) and a light disturbance in the cultural thicket community (polygon 1026071). Winged Spindle-tree (Euonymus alatus) exists in two of the forest communities (polygons 1026070 and 1026069) albeit at a lighter level of disturbance. Along with Common Buckthorn, Creeping Thistle (Cirsium arvense) provides a moderate disturbance to the cultural meadow community (polygon 1026065). This community also has what is currently a light level of infestation by the invasive Amur Maple (Acer ginnala), a prolific producer of seeds, and which may, in time, overgrow this open community to become a cultural thicket. The cultural woodland community (polygon 1026064) has, in addition to Common Buckthorn, a moderate level of infestation by Crack Willow (Salix fragilis), and Goutweed (Aegopodium podagraria), and a lesser level of abundance of invasive Ornamental Jewelweed (Impatiens glandulifera). Other problematic invasive species present at this site, but at lower occurrence levels are Manitoba Maple (Acer negundo), Reed Manna-grass (Glyceria maxima), Dame’s Rocket (Hesperis matronalis), Tartarian Honeysuckle (Lonicera tartarica) and Purple Loosestrife (Lythrum salicaria). Several other types of disturbance impact this natural area in addition to invasive species. Small, localized forest canopy gaps occur in the forest communities. Canopy gaps are somewhat larger and more widespread in the cultural woodland community (probably due to historical impacts) and in the mixed swamp community (probably due to toppling of trees in saturated soils). The valley slope communities have localized well-marked tracks, mostly accessing the valley bottom from the homes above. On the valley bottom the tracks are less clear, most probably due to the lush vegetation and more diffuse use by recreational fishermen and ATV use.

Low levels of noise are localized to widespread in this natural area. Light to moderate amounts of localized garbage dumping over the valley edge is associated with some of the current houses and there are small, localized amounts of earth displacement also associated with the houses. The forest communities show localized damage from tree diseases. Ecological Features and Functions This area contains wetlands that are part of the Churchville-Norval Provincially Significant Wetland Complex. With forest communities greater than 4 hectares and wetland over 0.5 hectares in size, this natural area has the potential to support and sustain biodiversity, healthy ecosystem functions and to provide long-term resilience for the natural system. Camp Robogi and Area includes riparian areas of the Credit River, providing a transitional zone between terrestrial and aquatic habitats, helping to maintain the quality of the river, and providing a movement corridor for plants and wildlife. By containing a relatively high number of habitat types, this natural area has the potential for high biodiversity function, particularly for species that require more than one habitat type for their life needs. One of the communities in this natural area contains an inclusion of a regionally rare vegetation type, and thus the area has the potential to support additional biodiversity above and beyond that found in common community types. This natural area makes a substantial contribution to providing a continuous vegetated corridor along the valley of the Credit River. In the upstream direction the west valley wall is naturally vegetated although the floodplain is occupied by the village of Norval. However there is good connection all along the river in this natural area with the natural vegetation of the east side of the river. In the downstream direction, the vegetated valley wall continues across Heritage Road with more natural habitat. At the southern part of the area, the floodplain is largely in agricultural land use although there is a narrow riparian strip immediately adjacent to the river. As a part of the provincial Greenbelt Plan Protected Countryside - Natural Heritage System this area contributes to connectivity between major provincial corridors, and allows for migration of species across large areas of the province. The Credit River runs alongside Camp Robogi and Area and thus this natural area supports the connectivity function of the Credit River and its tributaries by providing a natural habitat corridor that facilitates the cross-regional movement between major provincial corridors. One of the communities at this site contains numerous seepage areas. This site supports five Species At Risk (one plant species, two bird species, one butterfly species, one extirpated but re-introduced fish species), two provincially rare species (one plant species, one butterfly species) and eight regionally rare plant species. The forest communities at this site are large enough to support a species of area-sensitive forest interior bird. This area also supports a grassland bird species and one raptor species. Three frog/toad species were detected at this site suggesting that this area may supports amphibian breeding. Based on the above features, this area should be evaluated to determine if significant wildlife habitat is present, in accordance with the Provincial Policy Statement, Region of Peel Official Plan, and Brampton Official Plan. One of the communities in this natural area contains a vegetation inclusion that is an abundant producer of mast (nuts).

Recommendations 1. Invasive Species Control: Some of the invasive species at this site are transformer-type, and

thus pose a significant threat to the native plant communities due to their aggressive nature. Although this type of invasive species can be difficult to eliminate, any progress that can be made to control it is beneficial in reducing the impact on the natural community. As most of this natural area is in private ownership, landowners should be provided support to control of invasive species, as the quality of habitat along the Credit River corridor impacts the quality of the river and the ecosystem services the habitat provides. Control measures that are undertaken would have to be continued for several years until native vegetation increases to dominate the communities.

2. Meadow Maintenance: Patches of meadow at this site provide habitat for grassland species. Maintaining this habitat as meadow, preventing it from undergoing succession to treed communities, would help maintain habitat diversity, resulting in higher biodiversity over the whole natural area. Mowing every three to five years in the late summer after grassland birds have fledged would maintain the area as a meadow habitat.

3. Erosion Protection: Wherever possible, disturbance-caused erosion of the valley walls should

be remediated. Erosion has been caused by both removal of vegetation that exposes soils to direct wind and water and where recreational tracks and trails cut down the steep valley walls.

4. Species At Risk Habitat: Species At Risk were found in this natural area and detailed

assessments of their habitat conditions are recommended, in order to identify actions that may help to retain or enhance the habitat for the SAR.

5. Butternut Health Assessment: The health of the Butternut trees present at this site could be

assessed by a Butternut Assessor to determine whether any are candidates for inclusion in the Butternut Recovery Program.

6. Additional Inventory Work: Additional ecological knowledge about Camp Robogi and Area

could be gained by performing additional inventories. a. ELC: Access for the whole natural area was not available at the time this field work was

done. Knowledge about this natural area as a whole would benefit if additional access could be obtained and ELC completed for these portions of the area with data gaps.

b. Amphibians: The riparian areas and wetlands at this site provide potential habitat for amphibian species, which should be inventoried to better understand biodiversity at this site. The amphibian habitat at this site is too far from roads to be able to do road call inventories so walk-in inventories are recommended.

c. Breeding Birds: Camp Robogi and Area may be a site where breeding bird surveys could be productive.

d. Dragonflies/Damselflies: The meadow and river communities at this site may provide for a diversity of dragonflies/damselflies, so odonate inventories are recommended..
