University of Florida Conservation Area Land Management Plan
Bartram-Carr Woods









Introduction


Bartram-Carr Woods is the name of an almost 9-acre upland hardwood located between Center Drive
and Newell Drive, west and south of the Frazier Rogers and Bartram-Carr buildings. This area was
identified in previous master plans as a Preservation Area (11), due to the water quality, flood control
and erosion abatement benefits the area provided. While these functions are still present, since that time
portions of the understory have been taken over by invasive non-native plants that cover most of the
ground and are winding up many of the pines and hardwoods.

The primary use of the property is as a respite from the hustle and bustle of campus for local building
residents and as a pass through, or short cut, for people walking from health center facilities (south) to
the other areas of campus (north & west).There are two cleared areas that bookend the woods on the
southern side along the creek that provide sitting areas and picnic benches (the eastern cleared area is
also known as Health Center Park). Additionally, some departments use this Conservation Area as an
outdoor teaching area, due to its close proximity to the main campus.

Natural Area Inventory

Water Resources
Two unnamed creeks converge in the southern floodplain of Bartram-Carr Woods, flowing westward
and ultimately into Lake Alice. These creeks receive their flow from stormwater runoff and seepage
from upstream areas on the eastern quadrant of campus including the health center facilities to the south
and areas around Museum Road to the north. Additionally, flow from areas east of US 441 (S.W. 13th
Street) around Norman Hall and Sorority Row also contributes to these creeks.

Upstream of this Conservation Area, both creeks show heavy side bank erosion and down cutting due to
the lack of upstream stormwater treatment and the high amount of impervious surface. Due to safety
concerns, these creeks will need to have some instream counter measures like riprap added to prevent
further erosion. After convergence, the creek (the creek was at one time called Cal's Canal, named after
the person who oversaw its channelization) becomes fairly flat and begins to show the results of
upstream erosion in the form of sedimentation buildup. In fact, the creek in this area acts effectively as a
sediment trap in that water velocity slows down and allows for particulate matter to settle out. However,
this sedimentation buildup creates a need for regular dredging so that the floodplain does not rise and
culverts do not get filled in.

These woods contribute relatively small amounts of run-off to the main creek. Unlike impervious
surfaces, water is taken up and slowed down by vegetation and recharge to the surficial aquifer.
According to mapping completed by Casseaux and Ellington Inc., wetland and floodplain portions of
this Conservation Area buffer the creek's path, with wetlands extending just slightly past the creek's
normal flow path and floodplains extending further up bank to a maximum of 300 feet from the creek's
edge. In a few areas stormwater outfalls empty into the woods, functioning like intermittent streams that
only flow to the creek during large storm events. The base of these stormwater outlets (where the
erosion is greatest) should be studied as potential locations for rain gardens or other treatment BMPs to
treat and reduce velocities of stormwater empting into the woods. An issue observed by the working
group that inventoried this area was the unnecessary mowing along the north side of the creek.






























Natural Communities
Bartram-Carr Woods is comprised primarily of a mesic / upland-mixed hardwood forest. Upland
mixed forests are characterized as well-developed, closed-canopy forests of upland hardwoods on
rolling hills. Upland mixed forests often have limestone or phosphatic rock near the surface and
occasionally as outcrops. Soils are generally sandy-clays or clayey sands with substantial organic
and often calcareous components. In larger, less strenuous conditions, mesic forests typically support
significant wildlife and plant diversity, which result from the nutrient rich nature of hardwood
forests and flowering and fruiting plants. A formal plant and animal survey has been completed for
this area.

Plant Species
This mixed hardwoods canopy is dominated by Celtis laevigata (Hackberry), Liquidambar
styraciflua (Sweetgum), Pinus taeda (Loblolly Pine), Prunus caroliniana (Carolina Laurelcherry),
Quercus hemisphaerica (Upland Laurel Oak), Quercus nigra (Water Oak), Quercus shumardii
(Shumard's Oak) and Quercus virginiana (Live Oak). Also present are Carya glabra (Pignut
Hickory), Fraxinus americana (White Ash), Magnolia grandiflora (Southern Magnolia), Morus
rubra (Red Mulberry), Persea borbonia (Red Bay), Prunus serotina (Black Cherry),
Quercus michauxii (Basket Oak), and Sabalpalmetto (Cabbage Palm).

Native understory shrubs, vines and herbaceous species include Bignonia capreolata (Crossvine),
Callicarpa americana (American Beautyberry), Campsis radicans (Trumpet Creeper), Cocculus
carolinus (Carolina coralbead), Cornus asperifolia (Roughleaf Dogwood), Crataegus uniflora (Dwarf
Hawthorne), Elephantopus carolinianus (Carolina Elephantsfoot), Erythrina herbacea (Coralbean),
Eupatorium capillifolium (Dogfennel), Ilex vomitoria (Yaupon), Oplismenus hirtellus (Woodsgrass),
Phytolacca americana var. rigida (American Pokeweed), Pleopeltispolypodioides (Resurrection Fern),
Ruellia caroliniensis (Carolina Wild Petunia), Sabal minor (Bluestem Palm), various Smilax
(Greenbriar) species, Toxicodendron radicans (Poison Ivy), Vernonia gigantea (Giant Ironweed), and
Vitis rotundifolia (Muscadine Grape).









Despite the abundance of exotic invasive plants in this natural area, a few noteworthy natives
manage to persist. These include Arisaema dracontium (Greendragon, an uncommon species),
Clematis catesbyana (Satincurls, an uncommon species), Cocculus carolinus (Carolina Coralbead,
an uncommon species, located in the small strip just below Bartram and Carr Halls and in the
western part of the natural area) and Mateleafloridana (Florida Milkvine, endangered-FL, in
western part).

Invasive non-native plant species
Future management of the site will need to address invasive plant management. Non-native trees
common throughout include Cinnamomum camphora (Camphor Tree) and Ligustrum lucidum.
Occasionally found were Ehretia acuminata (Kodo Wood), Lagerstroemia indica (Crapemyrtle), Melia
azedarach (Chinaberry Tree), Pistachia chinensis (Chinese Pistachio) and Podocarpus macrophyllus
(Yew Plumpine). The understory is dominated by a suite of invasive exotics, most notably Ardisia
crenata (Scratchthroat), Dioscorea bulbifera (Air Potato) and Macfadyena unguis-cati (Catclaw Vine).
In places these species have completely taken over: Ardisia at the ground level, and the vines covering
the ground, small shrubs, and climbing up many of the trees. Other less abundant non-native shrubs and
vines include Ipomoea cairica (Mile a Minute Vine), Lantana camera (Lantana, quite common at edges
of property), Lygodiumjaponicum (Japanese Climbing Fern, at western end of area). Colocasia
esculenta (Wild Yam) is common in the steam running along the southern end of the property.

Animal Species
Bartram-Carr Woods is relatively small in size, which limits the amount of habitat for terrestrial
species. American Crow, American Goldfinch, American Robin, Bald Eagle, Baltimore Oriole,
Black and White Warbler, Belted Kingfisher, Blue-Gray gnatcatcher, Brown-headed cowbird, Blue-
headed Vireo, Blue Jay, Brown Thrasher, Boat-tailed Grackle, Carolina Chickadee, Carolina Wren,
Cedar Waxwing, Common Grackle, Downy Woodpecker, Eastern Bluebird, Eastern Phoebe, Eastern
Tufted Titmouse, Fish Crow, Great Crested Flycatcher, Gray Catbird, Hermit Thrush, House Finch,
Killdeer, Mourning Dove, Northern Cardinal, Northern Flicker, Northern Mockingbird, Northern
Parula, Osprey, Palm Warbler, Pine Warbler, Pileated Woodpecker, Red-bellied Woodpecker, Ruby-
crowned Kinglet, Rock Dove, Red-Shouldered Hawk, Red-winged Blackbird, White-eyed Vireo
Yellow-bellied Sapsucker, Yellow-rumped Warbler, Yellow-throated Warbler, Brown Anole, Gray
Squirrel, Cotton Mouse (1), Black rat (2), Raccoon and Opossum.

Soils Inventory
The following soil information for on-site soils was gathered from the Soil Survey of Alachua
County (1985).

Blichton Sand Urban Land Complex (0-5% slope)
This gently sloping, poorly drained soil is on gently rolling uplands. Slopes are slightly convex. The
areas are mostly irregular in shape and elongated and range from 10 to 40 acres. Typically, the
surface layer is dark brown sand about 6 inches thick.

Millhopper Sand Urban Land Complex (0-5% slope)
This nearly level to gently sloping, moderately well drained soil is in small and large irregularly
shaped areas on uplands and slightly rolling knolls in the broad flatwoods. Typically, the surface
layer is dark grayish brown sand about 9 inches thick. The subsurface layer is sand or fine sand
about 49 inches thick.

Cultural and Passive Recreational Resources
Bartram-Carr Woods serves primarily as a quiet walking area for residents of the surrounding offices
and classrooms and as a cut through for people walking between health center facilities and other areas
of campus. While there are a number of footpaths through the park, there are no designated trails or
related trail amenities present. However, adjacent to the creek on both the southwestern and
southeastern sides a few benches and picnic tables are present. Currently, Environmental Health &
Safety has a parking area that is partially within the Conservation boundary of these Woods. There
are no known archeological or historic sites within the Park.

Future Improvements

Due to its primarily upland characteristics along with its creek corridor, this wooded area's future
improvements should look at ways to enhance its function as a Nature Park. As such, the vision for
this area should be of a hybrid variety mixing characteristics of a more traditional park with those of









a managed natural area that also lends itself to use as a teaching resource for class observation. Thus,
the understory of this Conservation Area, which is being taken over by air-potato vine, needs to be
thinned creating a more inviting park like setting. One major improvement that has been
recommended is the need to formalize trails. Trails within the wooded areas should be designated
and mulched, with unnecessary ones blocked off with plantings, boulders or tree felling. On the
south-side of the creek completion of a mostly existing paved bicycle/pedestrian path is proposed
that is part of a campus and community-wide network of greenways. While on the north side of the
creek proposals include a naturalistic pedestrian trail, mulched instead of paved, that follows the
creek (east-west) and also connects into a north-south trail. Additionally, the north-south trail, which
runs the entire length of the woods, is envisioned as having a bridge crossing over the creek that
would connect into the bicycle/pedestrian greenway. Other improvements recommended for this
Conservation Area include habitat enhancements like bird and bat boxes and wildlife friendly
plantings, along with specimen tree plantings. Additionally, fencing, plantings, or a line of boulders
should be placed along the edge of the creek buffer, in order to stop unnecessary mowing, and along
Newell Drive to keep out unauthorized parking.

Long range management planning should look at replanting riparian vegetation with native species.
This replanting should strive to maintain the north side of the creek in a more naturalistic state of
floodplain forest, while maintaining the south-side of the creek in a landscaped open shrub-grass
state. Additionally, the area south and west of the Environmental Health & Safety (EH& S) offices
that is within the Conservation Area boundary should be reclaimed from its current use as a dirt
parking lot. This reclamation can occur once the parking area south of the EH& S building is
reconfigured in place. As part of this parking area improvement some light poles will need to be
moved and barriers put in place to prevent access into the conservation area by vehicles.
