U.S. Geological Survey, Greater Everglades Science Initiative (Place-Based Studies)
Fiscal Year 2003 Project Summary Report
Project Start Date: 2003 Project End Date: 2005
Location (Subregions, Counties, Park or Refuge): Florida Bay (Monroe County)
Funding Source: USGS's Greater Everglades Science Initiative (PBS)
Supporting Organizations: Audubon of Florida
Associated / Linked Projects:
Overview & Objective(s): This project is designed to evaluate the effect of hydrologic restoration on the nesting distribution and success of Roseate Spoonbills (Ajaia ajaia) in Florida Bay and surrounding mangrove estuarine habitats. This project is further designed to test hypotheses about the causal mechanisms of observed changes. The primary objectives are to (1) quantify the changes in spatial distribution and success of nesting spoonbills relative to hydrologic patterns, (2) use annual variation in hydrology in quasi-experimental context to test hypotheses about the causal mechanisms for observed changes, (3) establish a science-based criteria for nesting distribution and success to be used as a performance measure for hydrologic restoration, and (4) estimate demographic parameters.
Status: Funds were insufficient and arrived too late to conduct a full scale sampling effort during FY2003; thus we conducted a pilot investigation to refine our methods and to establish protocols. Preliminary surveys were conducted at all colonies in Florida Bay. A sample of nests (n=116) were monitored, and we banded a total of 25 chicks. An additional 162 chicks were banded at Tampa Bay for: (1) comparison to Florida Bay, (2) to establish whether linkages exist between Florida and Tampa Bay populations, and (3) to refine our marking protocols. Insufficient funds were available to conduct any work on Limpkins at this time.
Recent & Planned Products: 1st Annual Report (planned, 9/03); Presentation (USFWS, June 2003); Presentation (C-111, PDT Meeting, March 2003); Presentation (Geer Conference, April 2003); Avian Workshop Session (March 2003)
Relevance to Greater Everglades Restoration Information Needs: The re-establishment of healthy wading bird populations in the Everglades system has been at the forefront of restoration goals since its inception. As such the project elements listed below directly contribute to USGS Science Plan: Goal 1A, SO3, SO4; Goal; 2A - SG1 SG4; Goal 2B - SG1 SG3, SG4, SG5 and DOI Science Plan Chapter 3I, 4A.1, and 4C.
