The woodland is bounded on the east by the railway right-of-way. | 27.96145400, -81.70959000 | 43 | Growing on sugar sand in part shade to part sun of a remnant dry, xeric Lake Wales Ridge habitat. This site is in the middle of a highly developed suburban housing/light industrial area. The forest in this location is a fascinating example of what happens when fire is suppressed. Even under these conditions, with reduced overall diversity, the mature canopy of evergreens is under 7 meters. However, the shade created by the layers of vegetation are suppressing or eliminating open, low competition areas for species that require these conditions. Slope: 0 percent. Aspect: N/A. Soil: The soil of this site is characterized as St. Lucie Series fine sand, 0 to 5 percent slopes; with other minor contributions from Archbold, Myakka, and Cassia not described here. The St. Lucie Series consists of very deep, excessively drained soils that formed in sandy marine and/or eolian deposits. St. Lucie soils are on dunes, ridges, and knolls on marine terraces. Slopes range from linear to convex and range from 0 to 20 percent. This soil is strongly to extremely acid in the upper 200 cm of the horizon but can have neutral to alkaline components as well. The genesis of the St. Lucie soils is not clearly understood. No subsurface diagnostic horizons are within depths of 2 meters, but the uncoated sand grains suggest an albic horizon.

Geology: This collecting site straddles two geological formations: Cypresshead Formation (1) and Reworked Cypresshead Sediments (2) which follow. (1) The Cypresshead Formation named by Huddlestun (1988), is composed of siliciclastics is of Pliocene origin and occurs only in the Florida peninsula and eastern Georgia. It is at or near the surface from northern Nassau County southward to Highlands County forming the peninsular highlands. It appears that the Cypresshead Formation occurs in the subsurface southward from the outcrop region and similar sediments, the Long Key Formation, underlay the Florida Keys. The Cypresshead Formation is a shallow marine, near shore deposit equivalent to the Citronelle Formation deltaic sediments and the Miccosukee Formation prodeltaic sediments. The Cypresshead Formation consists of reddish brown to reddish orange, unconsolidated to poorly consolidated, fine to very coarse grained, clean to clayey sands. Cross bedded sands are common within the formation. Discoid quartzite pebbles and mica are often present. Clay beds are scattered and not extensive. In general, the Cypresshead Formation in exposure occurs above 100 feet (30 meters) above mean sea level (msl). Original fossil material is not present in the sediments although poorly preserved molds and casts of mollusks and burrow structures are occasionally present. The presence of these fossil "ghosts" and trace fossils documents marine influence on deposition of the Cypresshead sediments. The permeable sands of the Cypresshead Formation form part of the surficial aquifer system.

This unit is the result of post depositional reworking of the Cypresshead siliciclastics. The sediments are fine to coarse quartz sands with scattered quartz gravel and varying percentages of clay matrix that is undifferentiated.

Convenient parking and access to the area is located on east side of Placid View Drive, 1.23 kilometers north of Florida State Road 70. | 27.21871700, -81.37911000 | 37 | Growing in full sun on the upper portion of a relatively hilly sugar sand, extremely dry, xeric Lake Wales Ridge habitat comprised of a diverse evergreen and deciduous plant community. The habitat is subjected to periodic prescribed fire; the last fire seems to have been more than 4 years ago. This site is a bit more complex with intergradation xeric, dry-mesic, moist-mesic habitats on the lower portion of slopes that lead to a small stream. As a result, there is more overlap in plant species where plant communities intersect. Slope: 0 to 5 percent. Aspect: Various. Soil: The soils here, where Tamala humilis grows and thrives, are primarily Archbold Series sand, 0 to 5 percent slopes and Satellite Series sand, 0 to 2 percent slopes with occasional intrusions of St. Lucie Series sand, 0 to 8 percent slopes. The Archbold Series consists of deep, well drained, very rapidly permeable sandy soils that formed in marine or eolian deposits. These droughty soils are on low ridges in central Florida. Slopes are typically 0 to 5 percent. The soil reaction is slightly to extremely acid. The soil is sand or fine sand throughout. The silt plus clay content in the 25-100 depth is less than 2 percent; even so, they contain slightly more moisture in times of abundant rainfall. The Satellite Series consists of very deep, somewhat poorly drained, rapidly permeable soils on low knolls and ridges of the Southern Florida Flatwoods and less commonly on the South-Central Florida Ridge They formed in thick beds of marine sand. Soil reaction ranges from very strongly acid to slightly alkaline in all horizon. This soil can become saturated 25-100 cm below the surface during the summer rainy season. The St. Lucie Series consists of very deep, excessively drained soils that formed in sandy marine and/or eolian deposits. St. Lucie Series soils are on dunes, ridges, and knolls on marine terraces. Slopes range from linear to convex and range from 0 to 20 percent. This soil is strongly to extremely acid in the upper 200 cm of the horizon but can have neutral to alkaline components as well. The genesis of the St. Lucie Series soil is not clearly understood. No subsurface diagnostic horizons are within depths of 2 meters, but the uncoated sand grains suggest an albic horizon.
