|a In the fall of 2005, U.S. Fish and Wildlife Services (USFWS) contracted with Florida
International University (FIU) to study the physical and biological drivers underlying the
distribution of woody plant species in the marl prairie habitat of the Cape Sable Seaside
Sparrow (CSSS). This report presents what we have learned about woody plant
encroachment based on studies carried out during the period 2006-2008. The freshwater
marl prairie habitat currently occupied by the Cape Sable seaside sparrow (CSSS;
Ammodramus maritimus mirabilis) is a dynamic mosaic comprised of species-rich
grassland communities and tree islands of various sizes, densities and compositions.
Landscape heterogeneity and the scale of vegetative components across the marl prairie is
primarily determined by hydrologic conditions, biological factors (e.g. dispersal and
growth morphology), and disturbances such as fire. The woody component of the marl
prairie landscape is subject to expansion through multiple positive feedback mechanisms,
which may be initiated by recent land use change (e.g. drainage). Because sparrows are
known to avoid areas where the woody component is too extensive, a better
understanding of invasion dynamics is needed to ensure proper management. |
