University of Florida Conservation Areas Land Management Plan
Harmonic Woods


Harmonic Woods is a 10-acre Conservation Area located north of Lake Alice on Museum Road and
bordered on the east by Fraternity Drive and on the west by Village Drive. This property is a relatively
undisturbed upland hardwood dominated forest, which slopes down to Lake Alice. Unlike many other
natural areas on campus these woods have not been taken over by invasive exotic plants, although
ardesia is fairly widespread. The primary use of the property has been by the Botany Department for
plant identification and by the Geomatics (Survey and Mapping) Department for teaching surveying
techniques in woods and on slopes. Due to its close proximity to campus, this site has been ideal for
these departments.

According to information from the 2000-2010 Campus Master Plan, the area was recommended for
preservation (Preservation Area 12) by several university staff and faculty members as well as
representatives from state and local environmental agencies, who value the area for its relatively pristine
condition and proximity to the campus. The protection of the resources provided by this area will
require the exclusion of development activity, including clearing, earthwork, and paving. Only minor
restoration along the forested edges is necessary, due to its relatively undisturbed condition.

Water Resources
Harmonic Woods does not contain any permanent water features, but does provide some water
resource protection, through recharge to the surficial aquifer and stormwater abatement. These
woods are immediately adjacent and upstream to Lake Alice and, therefore, provide the lake some
resource protection by being maintained in their undeveloped state.

Stormwater is a dominant watershed issue within the Lake Alice watershed. The current stormwater
permit with the St. Johns River Water Management District does not require additional stormwater
treatment for new impervious surfaces until a threshold is tripped (refer to CALM introduction),
however campus staff are looking for ways to incorporate new technologies into sites that will retain
and percolate water. In this light, the southwestern corner of the property could be potential location
for a rain garden retention area to treat upstream runoff before it enters Lake Alice.

Natural Communities
Harmonic 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.

Plant Species
The canopy is dominated by Carpinus caroliniana (American Hornbeam), 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), Carpinus caroliniana (American
Hornbeam), Celtis laevigata (Hackberry), Cercis canadensis (Eastern Redbud), Cornusflorida
(Flowering Dogwood), 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 austrina (Bastard White Oak), Quercus michauxii (Basket Oak), Quercus virginiana (Live
Oak), Sabal palmetto (Cabbage Palm), Sapindus saponaria (Soapberry), and Ulmus americana
(American Elm).

The understory is dominated by native species and houses a great diversity of small shrubs, vines
and herbaceous plants. These include: Aesculuspavia (Red Buckeye), Apios americana
(Groundnut), Aralia spinosa (Devil's Walking Stick), Arundinaria gigantea (Switchcane),
Asplenium platyneuron (Ebony Spleenwort), Bignonia capreolata (Crossvine), Boehmaria
cylindrica (False Nettle), Callicarpa americana (American Beautyberry), Campsis radicans
(Trumpet Creeper), Clematis reticulata (Netleaf Leatherflower), Crategus uniflora (Dwarf
Hawthorne), Erythrina herbacea (Coralbean), Euonymus americanus (American Strawberry Bush),
Gelsemium sempervirens (Yellow Jessamine), Hypericum hypericoides (St. Andrew's Cross), Ilex
vomitoria (Yaupon), Ipomoea cordatotriloba (Tievine), Mitchella repens (Partridgeberry), Myrica
cerifera (Wax Myrtle), Oplismenus hirtellus (Woodsgrass), Parthenocissus quinquefolia (Virginia
creeper), Phytolacca americana var. rigida (American Pokeweed), Rubus trivialis (Southern
Dewberry), Ruellia carolinense (Carolina Wild Petunia), Sabal minor (Bluestem Palm, found in the
wetter areas), Sambucus nigra subsp. canadensis (Elderberry), Sideroxylon lanuginosum (Gum
Bully), various Smilax (Greenbriar) species, Tillandsia usneoides (Spanish Moss), Toxicodendron
radicans (Poison Ivy), Trillium maculataum (Spotted Wakerobin), Vaccinium arboreum
(Sparkleberry), Vernonia gigantea (Giant Ironweed), Violapalmata (Early Blue Violet), Viola
sororia (Common Blue Violet), Viola walteri (Prostrate Blue Violet), Vitis rotundifolia (Muscadine
Grape), and Yuccafilamentosa (Adam's Needle).

Trillium maculataum (Spotted Wakerobin) and Smilax lasioneuron (Blueridge Carrionflower) are
two rare species found here that are at the southern edge of their range. Other native species of note
include Arisaema triphyllum (Jack in the Pulpit, an uncommon species), Arisaema dracontium
(Greendragon, an uncommon species), Athyriumfilix-femina subsp. asplenioides (Southern Lady
Fern, threatened FL, at the southern limit of its range), Clematis catesbyana (Satincurls, an
uncommon species), Collinsonia serotina (Blueridge Horsebalm, very rare), Dioscoreafloridana
(Florida Yam, an uncommon species), Mateleafloridana (Florida Milkvine, endangered-FL) and
Onosmodium virginianum (False Gromwell, an uncommon species) and the vine { Smilax hugeri
(Small) Norton ex Pennell}.

Invasive non-native plant species
Portions of this mature forest are being encroached upon by non-native species. The most
problematic areas include the southwest corner (on the moist lower slopes and in the lower
elevations), the western edge, and along the disturbed, extreme northern boundary. Ardisia crenata
(Scratchthroat) is the worst offender: this species is found scattered throughout the forest, and in
great abundance in the southwestern and at the north edge. In places along the bottom half of the
slope Ardisia dominates the understory; this monoculture is marching up the slope and beginning to
invade the small swale part-way up the slope that houses populations of Trillium maculatum
(Spotted Wakerobin) and Smilax lasioneuron (Blueridge Carrionflower). Also found in these wetter


areas but in less abundance are Elaeagnuspungens (Silverthorn), Hedera helix (English Ivy),
Liriope spicata (Border Grass), Macfadyana unguis-cati (Catclaw Vine), Nandina domestic
(Heavenly Bamboo), Trachelospermumjasminoides (Confederate Jasmine), and Urena lobata
(Caesarweed). Several fraternity houses and dorms neighbor Harmonic Woods to the north, and this
edge area is quite disturbed. Albiziajulibrissin (Mimosa), Dioscorea bulbifera (Air Potato; limited to
this portion of the property), Melia azedarach (Chinaberry Tree), Sapium sebiferum (Popcorn Tree),
Tradescantiafluminensis (Small Leaf Spiderwort), and Wisteria sinensis (Chinese Wisteria) occur
here. Non-native species found occasionally throughout the natural area include Cinnamomum
camphora (Camphortree), Eriobotryajaponica (Loquat), and Ligustrum lucidum (Glossy Privet).
Lantana camera (Lantana) was occasionally seen along the edges of the property.

Animal Species
Harmonic Woods is relatively small in size, which limits the amount of habitat for terrestrial species.

Soils Inventory
In general, mesic upland mixed / hardwood forests occur on rolling hills that 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. The topography and clayey
soils increase surface water runoff, although this is counterbalanced by the moisture retention
properties of clays and by the often thick layer of leaf mulch which helps conserve soil moisture and
create decidedly mesic conditions (FNAI).

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

Blichton 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 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 Recreational Resources
Harmonic Woods functions as forested green space for the student residents of Fraternity Row and
Corey Village. As stated previously, these woods are also important areas for the Botany and
Geomatics (Survey and Mapping) Departments, due to its close proximity to the main campus, intact
forest canopy with limited invasive exotic intrusion and sloping terrain. The woods are bisected with
unmarked footpaths and trails that are used by walkers and mountain bikers. On football game days,
tailgaters park along the grassy edge that rings the woods. At present, there are no picnic tables,
benches, or designated trails provided.

Southern portions of this site overlap with the potential archeological sites map, although no known
sites have been in identified.

Future Improvements

Harmonic Wood's physical attribute of being an upland forest strongly point towards a Nature Park
orientation, however the Botany and Geomatics departments also use this area for research and class
activities. Therefore, it should be considered as both Nature Park and Academic Preserve. Land
management activities should include creating designated footpaths, fencing along the northern
boundary to prevent fraternity and sorority houses from encroaching, mowing, and, or, dumping into
the woods and increasing the forest canopy along the borders. Additionally, habitat enhancements
like bird and bat boxes and wildlife friendly plantings should be considered for this site.
