Table 1. Ecological Criteria Scores by Natural Community Type. This is an areaweighted
average value score for each natural community present on site. Numbers in
bold have significant above average resource value (>3.0). Natural Communities in bold
have at least two of the content resource values (rarity, connectivity, and completeness)
above average (>3.0). Overall Ecological Value = 0.75

Key Features – This site is a fairly even mix of decent quality Scrub and Xeric
Hammock (mostly fire-suppressed Scrub) along a railroad right-of-way. There are at
least 4 rare species present here: scrub lizards, Chamaesyce cumulicola, Conradina
grandiflora, and Lechea cernua.
Importance – This area is noteworthy because it contains a lot of good quality
Scrub remnants with several rare species. It is adjacent to a conservation area, which
appears to be largely wetlands. Scrub, as a dry upland, has largely been developed
throughout the county.
Connectivity – Within 500 feet of existing conservation lands.
Proximity to Urban Areas – Site is within the city of Fort Pierce.
Proximity to primary and secondary roads – Within 500 feet of a major roadway.
Hydrology – The entire site is dry, well-drained sand. Along the southwest edge,
it drops down to a nearby wetland. The railroad probably has only minimal impact on
drainage.
