Project Proposal for 2001

FY 2001 WORK PLAN

Project Title: Evolution of Everglades Tree Islands
Project Chiefs: Debra Willard, William Orem
Email: dwillard@usgs.gov, borem@usgs.gov
Phone: 703-648-5320, 703-648-6273
Fax: 703-648-6953, 703-648-6419
Mailing address: U.S. Geological Survey, 926A National Center, Reston, VA 20192

Other participating programs: None
Ecosystem: South Florida
Project start date: 1 October 1999
Project end date: 30 September 2004

FY 2001 activities:

- Field work, sampling 2 islands/drowned islands in WCA 2, 3-4 islands in Everglades National Park, and 1 island in Loxahatchee NWR
- Preliminary palynological analysis of cores from islands sampled in FY 99-00
- Geochemical analyses on cores from FY99-00 work and some FY 2001
- Dating of key cores collected in FY 2001

FY 2001 deliverables/products:

- Publication of paper on development and decline of drowned tree island in WCA 2A
- Publication or report on regional patterns of vegetational development and geochemistry of tree islands sampled in Water Conservation Areas
- Preliminary reports on geochemistry and vegetational history from islands sampled in FY 2000

FY 2001 Outreach:

- Fact Sheet - Timing of tree-island formation and development
- News report in "Science" on tree-island issues in southern Florida; possible follow-up article on USGS/collaborative research on Florida tree islands

FY 2000 Products:

FY 2000 Field Activities:

March, 2000 - Collected transects of cores on 6 islands in WCA 3A, including a declining rookery island near the L67 canal; collected cores on 2 islands in Loxahatchee NWR

August, 2000 - Collected transects of cores on 4 islands in Everglades National Park and 1 declining tree island in WCA 2A

Collaborators, clients:

Tim Towles: Florida Game and Fresh-Water Fish Commission. Scientific collaboration and logistic support. Provide elevation and vegetation data from tree islands and guidance in tree-island selection.

Fred Sklar, Susan Newman, Tom Fontaine, Ken Rutchey, Yegang Wu, Steve Krupa, Cindy Bevier, Jeff Giddings: South Florida Water Management District. Scientific collaboration and logistic support.
