Monitoring Of Tree Island Condition In The Southern Everglades: Annual Report 2011, Jay P. Sah, Michael S. Ross, Pablo L. Ruiz, Suresh Subedi

SERC Research Reports

Tree islands, a prominent feature in both the marl prairie and ridge and slough landscapes of the Everglades, are sensitive to large-scale restoration actions associated with the Comprehensive Everglades Restoration Plan (CERP) authorized by the Water Resources Development Act (WRDA) 2000 to restore the south Florida ecosystem. More specifically, changes in hydrologic regimes at both local and landscape scales are likely to affect the internal water economy of islands, which in turn will influence plant community structure and function. To strengthen our ability to assess the “performance” of tree island ecosystems and predict how these hydrologic alterations would translate into …

A Geospatial Database Of Tree Islands Within The Mustang Corner Fire Incident Of 2008, Pablo L. Ruiz, Michael S. Ross, Jay P. Sah

SERC Research Reports

Fire, which affects community structure and composition at all trophic levels, is an integral component of the Everglades ecosystem (Wade et al. 1980; Lockwood et al. 2003). Without fire, the Everglades as we know it today would be a much different place. This is particularly true for the short-hydroperiod marl prairies that predominate on the eastern and western flanks of Shark River Slough, Everglades National Park (Figure 1). In general, fire in a tropical or sub-tropical grassland community favors the dominance of C4 grasses over C3 species (Roscoe et al. 2000; Briggs et al. 2005). Within this pyrogenic graminoid community …

Survival And Growth Responses Of Eight Everglades Tree Species Along An Experimental Hydrological Gradient On Two Tree Island Types, Susana L. Stoffella, Michael S. Ross, Jay P. Sah, René M. Price, Pamela L. Sullivan, Eric A. Cline, Leonard J. Scinto

FCE LTER Journal Articles

Questions: How are the early survival and growth of seedlings of Everglades tree species planted in an experimental setting on artificial tree islands affected by hydrology and substrate type? What are the implications of these responses for broader tree island restoration efforts?

Location: Loxahatchee Impoundment Landscape Assessment (LILA), Boynton Beach, Florida, USA.

Methods: An experiment was designed to test hydrological and substrate effects on seedling growth and survivorship. Two islands – a peat and a limestone-core island representing two major types found in the Everglades – were constructed in four macrocosms. A mixture of eight tree species was planted on …
