University of Florida Conservation Area Land Management Plan
Natural Areas Teaching Lab East
(Surge Wetland)








Introduction

The NATL-east Conservation Area (formerly Surge Wetland Conservation Area) is a 10.9-acre tract
adjacent to the Surge Area north of Archer Road on the southwest quadrant of the main campus. In the
spring of 2005 this area was made part of the Natural Area Teaching Laboratory (NATL).
Consequently, the Natural Area Advisory Committee (NAAC) has developed recommendations as to
how the area should be managed. This site occupies a depression basin that receives water from
surrounding areas on campus and from neighboring Archer Road. The central marsh is surrounded by
and grades into a shrub wetland/hydric hammock, and, farther up slope, a mesic mixed hardwood
hammock. The boundaries of these plant communities are not clearly defined and fluctuate depending
on rainfall patterns. NATL-east is relatively intact and for the most part is undisturbed by invasive
exotic plants.

This Conservation Area was recommended for preservation in the 1987 Stormwater Management
Master Plan due to it hydrological sensitivity and its proximity to NATL. The 2000-2010 Campus
Master Plan identified upland portions of this area as Preservation Area 2.

Water Resources
According to watershed analysis work completed by Causseaux and Ellington, NATL-east Conservation
Area is in a depression basin. This area receives stormwater from the surrounding campus lands and from
Archer Road. Water exits this conservation area via an intermittent drainage canal that drains into a
sinkhole pond adjacent to Archer Road in the southeast area of the Natural Areas Teaching Lab
Conservation Area. Surge Area Drive, the road between the southern portion of these two Conservation
Areas, floods when large rainfall events occur, which blocks off access to and from Archer Road. Future
stormwater improvements may be necessary on site with two potential options including raising the
elevation of the road or creating more storage in the wetland. Any stormwater improvements should be
coordinated with the Department of Transportation, which is responsible for some of the water entering the
conservation area.


NATL-east Interior Surge Area Dnve Flooding








Natural Communities
NATL-east is comprised of primarily two natural community types. The center of the Conservation
Area is composed of a shrub wetland that appears to transition from a marsh to shrub based on rainfall
over time. When rainfall is heavy and persistent the shrubs die back and marsh vegetation takes over,
whereas during drought years shrubs and hardwoods encroach into the interior. Moving up slope, a
small area of bottomland forest rings the shrub wetland areas. Moving farther up slope, bottomland areas
transition into an upland forest comprised primarily of a mesic / upland-mixed hardwood forest. A
variety of native plant species are found here, with the highest diversity occurring in the mesic
hammock. Mesic forests typically support significant wildlife and plant diversity, which result from the
nutrient rich nature of hardwood forests and flowering and fruiting plants. The following plants species
have been documented on site.

Plant Species
The canopy of the mesic hammock is dominated by Carya glabra (Pignut Hickory), Liquidambar
styraciflua (Sweetgum), Ostrya virginiana (Eastern Hophorbeam), Pinus taeda (Loblolly Pine),
Quercus hemisphaerica (Upland Laurel Oak), Quercus nigra (Water Oak), Tilia americana var.
caroliniana (Carolina Basswood) and Ulmus alata (Winged Elm). Also present are Acer negundo
(Boxelder), Acer rubrum (Red Maple), Celtis laevigata (Hackberry), Chionanthus virginicus (White
Fringetree), Diospyros virginiana (Common Persimmon), Fraxinus americana (White Ash), Juniperis
virginiana (Red Cedar), Magnolia grandiflora (Southern Magnolia), Morus rubra (Red Mulberry),
Prunus caroliniana (Carolina Laurelcherry), Prunus umbellata (Black Cherry), Quercus geminata (Sand
Live Oak), Quercus michauxii (Basket Oak) and Quercus virginiana (Live Oak).

The understory associated with the mesic hammock is quite diverse and dominated by a variety of native
species. Low shrubs, herbaceous plants and vines documented in this area include Asiminaparviflora
(Smallflower Pawpaw, Asplenium platyneuron (Ebony spleenwort), Bignonia capreolata (Crossvine),
Callicarpa americana (American beautyberry), Campsis radicans (Trumpet creeper), Crategus uniflora
(Dwarf Hawthorne), Dioscoreafloridana (Florida Yam), Erythrina herbacea (Coralbean), Euonymus
americanus (American Strawberrybush), Eupatorium capillifolium (Dogfennel), Gelsemium
sempervirens (Yellow Jessamine), Lonicera sempervirens (Coral Honeysuckle), Mitchella repens
(Partridgeberry), Myrica cerifera (Wax Myrtle), Parthenocissus quinquefolius (Virginia Creeper),
Phytolacca americana var. rigida (American Pokeweed), Rubus trivialis (Southern Dewberry), a variety
of Smilax (Greenbriar) species, Toxicodendron radicans (Poison Ivy), Vaccinium arboreum
(Sparkleberry), Vernonia gigantea (Giant Ironweed), Vitis aestivalis (Summer Grape) and
Yuccafilamentosa (Adam's Needle).

Dominant trees and shrubs observed in the wetland areas include Acer rubrum, (red maple), Celtis
laevigata (Hackberry), Cephalanthus occidentalis (Common Buttonbush), Liquidambar styraciflua
(Sweetgum), Myrica cerifera (Wax Myrtle), Nyssa sylvatica var. biflora (Swamp Tupelo) and Salix
caroliniana (Carolina willow). Also present are Diospyros virginiana (Common Persimmon), Quercus
laurifolia (Diamond Leaf Oak), Quercus nigra (Water Oak), Rhus copallinum (Winged Sumac) and
Sambucus nigra subsp. canadensis (Elderberry). Herbaceous plants, vines, and ferns common in the
wetter areas include Apios americana (Groundnut), Decumaria barbara (Climbing Hydrangea),
Hydrocotyle umbellata (Manyflower Marshpennywort), Osmunda cinnamomea (Cinnamon fern),
Osmunda regalis var. spectabilis (Royal Fern), Pontederia cordata (Pickerelweed), Thelypteris kunthii
(Southern Shield Fern) Thelypterispalustris var. pubescens (Marsh Fern), Woodwardia areolata (Netted
Chain Fern) and Woodwardia virginica (Virginia Chain Fern).








Uncommon and rare species growing in NATL-east include Arisaema dracontium (Green Dragon, an
uncommon species, occasional), Dioscoreafloridana (Florida Yam, an uncommon species) and Matelea
sp. (Milkvine, not yet identified, must wait for it to flower).

Invasive Non-Native Plant Species
Overall the woods appear to be in good shape and not overly dominated by exotic species. However,
Colocasia esculenta (Wild Taro), Myriophyllum aquaticum (Parrotfeather Water Milfoil), and
Eichhornia crassipes (Common Water Hyacinth) are common in the wet areas. Broussonetiapapyrifera
(Paper Mulberry), Ludwigiaperuviana (Peruvian Primrosewillow) and Salvinia minima (Water
Spangles) were occasionally encountered. The most problematic invasive exotic observed in the mesic
hammock was Ardisia crenata (Scratchthroat). Only occasionally found in the majority of the woods,
this species becomes abundant in the extreme northwestern corner of the mesic hammock (north and
west of the wetlands), particularly along the northern fence. Other non-native species occasionally
observed in the mesic hammock include Dioscorea bulbifera (Air Potato, present on the eastern edge of
the property), Eriobotryajaponica (Loquat, occasional throughout), Lantana camera (Lantana, at
property edges), Ligustrum lucidum (Glossy Privet, occasional throughout), Ligustrum sinense (Chinese
Privet, throughout), Ruellia tweediana (Britton's Wild Petunia, at western edge) and
Syngonium podophyllum (American Evergreen, at east edge).

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

Bonneau Fine Sand
This gently sloping, moderately well drained soil is in small to relatively large areas on uplands. Slopes
are generally convex. Typically, the surface layer is dark gray fine sand about 9 inches thick. The
subsurface layer is brownish yellow fine sand to a depth of 29 inches. The Bonneau soil has a water
table that is at a depth of 40 to 60 inches for 1 to 3 months and at a depth of 60 to 72 inches for 2 to 3
months during most years. Surface runoff is slow. Permeability is moderately slow to moderate in the
upper part of the subsoil and very slow to slow in the lower part.

Lochloosa Fine Sand
This gently sloping, somewhat poorly drained soil is in small and large areas on the rolling uplands.
Typically, the surface layer is dark gray fine sand about 7 inches thick. The subsurface layer is yellowish
brown loamy sand or sand to a depth of 31 inches. This soil has a water table that is about 30 to 40
inches below the surface for 1 to 4 months during most years. Surface runoff is slow. The available
water capacity is low to medium in the sandy surface and subsurface layers and medium in the subsoil.

Monteocha Loamy Sand
This nearly level, very poorly drained soil is in wet ponds and shallow depressional areas in the flat
woods. Slopes are less than 2 percent. Typically, the surface layer is black loamy sand about 12 inches
thick. The subsurface layer is light brownish gray sand to a depth of 18 inches. The Monteocha soil has
a water table that is within 10 inches of the surface for more than 6 months during most years.

Cultural and Passive Recreational Resources
NATL-east does not have any public access or associated amenities. There are no known archeological
or historic sites within the Conservation Area.

Future Improvements

The NATL-east is considered an Academic Preserve, with teaching /research, public education and
physical improvements overseen by the Natural Area Advisory Committee (NAAC).

In the spring of 2005, the Natural Area Advisory Committee (NAAC) recommended improvements for
NATL-east in order to begin its use as an outdoor teaching laboratory. (Please note that because CALM
plans are updated only annually, NAAC may have modified its recommendations. For its current
recommendations see http://natl.ifas.ufl.edu/NATLlrPlans.htm.). The committee recommends that
NATL-east have two entrances. An existing, north entrance is on Natural Area Drive, across the street
from and slightly south of the academic entrance to NATL-west. A south entrance would be across the
street from the southeast portion of NATL-west, where a new entrance into NATL-west would facilitate
passage between NATL's two conservation areas. Each entrance will have signs stating that the areas
are for academic use only and directing would-be users to the public area of NATL-west and to rules
posted on the NATL website. At NATL-east's north entrance a kiosk, out of sight from the road and
with a trash can, will provide an introduction to the area's habitats and rules for use. A foot trail west of
the central marsh will run between the north and south entrances. Fencing is a major concern, and
NAAC recommends that an existing corral-type fence be extended along Natural Area/Surge Area Drive
south to the UF housing compound and from the compound south to Archer Road. Additionally, it








recommends that hurricane fences be erected along the eastern and southern sides of the Conservation
Area (along with a trash trap at the DOT drainage outfalls) and that the field fence along the northern
boundary be removed (leaving an existing hurricane fence).

The committee recommends a number of improvements needed to promote academic uses in line with
ongoing activities in NATL-west. These include extensions of NATL-west's 50-meter grid (surveyed by
the Student Geomatics Association), its grid-based soil survey (by Soil and Water Science personnel),
and its grid-based photographic record of vegetation (photographs in the four cardinal directions at each
grid stake, first taken in NATL-west in January 1997). Because there will be no grid stakes in the central
pond, photographs should be taken at specific stations around the pond to record the pond's features.
Similarly the biotic surveys of NATL-west should be expanded to include NATL-east.

NAAC is concerned about the noise emanating from the carpentry shop blower in Housing's adjacent
work compound. It plans to investigate means to reduce the noise but has not settled on a specific
recommendation. After the entrances and trail have been created, the committee plans to have a grand
opening that will also serve as an opportunity to recruit volunteers to help clean up trash that has built up
in the area over the years.

Finally, a Stormwater Agreement between the University and Emmer Development was approved by
Lakes, Vegetation and Landscaping at its 12 Jan 2004 meeting. This agreement identified potential
means that could be used to improve the quality of water flowing from the Surge Wetland into a
sinkhole in NATL-west and were listed in the minutes of this meeting (
http://www.facilities.ufl.edu/lvl/minutes/LVL%20Minutes%201-12-04FINAL.pdf ), but the final design
is pending
