r i, Scrubby Flatwoods The scrubby pine flatwoods scrub habitat type was identified within the North Sebastian Conservation Area and along the western boundary of the Sebastian Airport compensation properties. It is vegetatively characterized by a shrub layer dominated by saw palmetto interspersed by scrub oaks and an open to closed canopy of slash pine. Soils of the scrubby flatwoods identified on the subject compensation areas are the nearly level, poorly drained Myakka and Immokalee sands and the nearly level, somewhat poorly drained Satellite sands (Wettstein et a/. 1987). Mesic Flatwoods Mesic flatwoods are the predominant matrix habitat type of the scrub landscapes within the Scrub -Jay Habitat Compensation Areas. This natural community type is common on the North Sebastian Conservation Area/Sebastian Airport compensation sites and Wabasso Scrub Conservation Area. It is vegetatively characterized by a dense slash pine canopy with a shrubby understory dominated by saw palmetto, fetterbush, and galiberry. Herbaceous ground cover, dominated by wiregrass, is sparse due to either a thick layer of pine needle duff or the dense shrub layer. Cabbage palm is scattered within the mesic slash pine canopy at the North Sebastian Conservation Area. Soil stypes of the mesic flatwoods on the Scrub -Jay Habitat Compensation Areas are the nearly level, poorly drained Myakka, EauGaliie, and Immokalee fine sands (Wettstein et a/. 1987). Qaimetto - Lyonia Shr I•ind The palmetto-lyonia shrubland classification is applied to describe a natural community that is essentially a rnesic flatwoods without the pine canopy component. This habitat type is identified within the North Sebastian Conservation Area and Wabasso Scrub Conservation Area. The dense shrub community characterizing this habitat is dominated by saw palmetto, fetterbush, and galiberry on the same Myakka and Immokalee fine sand soils (Wettstein et a/. 1987) as the mesic pine flatwoods Distur ed -Lands This land use classification type is used to describe vegetatively disturbed areas on poorly drained soils dominated by Brazilian pepper (Schinus terebinthifo/&us), an exotic and invasive species and/or grape vine, a native species that rapidly colonizes disturbed sites. p rQ.gA(narsh ItIla id Swamp Numerous, isolated depression marshes are interspersed within the scrub landscapes at the North Sebastian Conservation Area/Sebastian Airport and the Wabasso Scrub Conservation Area, They are formed on the very poorly drained Myakka fine sand, 46
