Monitoring Of Tree Island Condition In The Southern Everglades: Hydrologic Driven Decadal Changes In Tree Island Woody Vegetation Structure And Composition: 2012 Annual Report, Pablo L. Ruiz, Michael S. Ross, Jay P. Sah
SERC Research Reports
This report examines the interaction between hydrology and vegetation over a 10-year period, between 2001/02 and 2012 within six permanent tree island plots located on three tree islands, two plots each per tree island, established in 2001/02, along a hydrologic and productivity gradient. We hypothesize that: (H1) hydrologic differences within plots between census dates will result in marked differences in a) tree and sapling densities, b) tree basal area, and c) forest structure, i.e., canopy volume and height, and (H2) tree island growth, development, and succession is dependent on hydrologic fluxes, particularly during periods of prolonged droughts or below average …

Monitoring Of Tree Island Conditions In The Southern Everglades: The Effects Of Hurricanes And Hydrology On The Status And Population Dynamics Of Sixteen Tropical Hardwood Hammock Tree Islands, Pablo L. Ruiz, Jay P. Sah, Michael S. Ross, Diana L. Rodriguez, Allison M. Lambert
SERC Research Reports
In 2005 we began a multi-year intensive monitoring and assessment study of tropical hardwood hammocks within two distinct hydrologic regions in Everglades National Park, under funding from the CERP Monitoring and Assessment Program. In serving as an Annual Report for 2010, this document, reports in detail on the population dynamics and status of tropical hardwood hammocks in Shark Slough and adjacent marl prairies during a 4-year period between 2005 and 2009. 2005-09 was a period that saw a marked drawdown in marsh water levels (July 2006 - July 2008), and an active hurricane season in 2005 with two hurricanes, Hurricane …

SERC Research Reports
This document summarizes the activities that were accomplished in 2008, the sixth year of the research project “Effect of hydrologic restoration on the habitat of the Cape Sable seaside sparrow”, a collaborative effort among the US Army Corps of Engineers, Everglades National Park, Florida International University, and the US Geological Survey (Florida Integrated Science Center). The major activities in 2008 included field work, data analysis, and presentations. Jay Sah presented the results of 6th year field work at the Cape Sable seaside sparrow (CSSS) Fire Meeting 2008, held on December 2-3 at the Krome Center, Homestead, Florida. In the same …

The major activities in Year 3 on ‘Effect of hydrologic restoration on the habitat of the Cape Sable seaside sparrow (CSSS)’ included presentations, field work, data analysis, and report preparation. During this period, we made 4 presentations, two at the CSSS – fire planning workshops at Everglades National Park (ENP), one at the Society of Wetland Scientists’ meeting in Charleston, SC, and a fourth at the Marl Prairie/CSSS performance measure workshop at ENP. We started field work in the third week of January and continued till June 3, 2005. Early in the field season, we completed vegetation surveys along two …
Tree Islands In Everglades Landscapes: Current Status, Historical Changes, And Hydrologic Impacts On Population Dynamics And Moisture Relations, First Annual Report, Michael Ross, Steve Oberbauer, Pablo Ruiz, Nilesh Timilsina, Daniel Gomez, Jay Sah, Susanna Stofella, Leonel Sternberg
Tree Islands In Everglades Landscapes: Current Status, Historical Changes, And Hydrologic Impacts On Population Dynamics And Moisture Relations, First Annual Report, Michael Ross, Steve Oberbauer, Pablo Ruiz, Nilesh Timilsina, Daniel Gomez, Jay Sah, Susanna Stofella, Leonel Sternberg
SERC Research Reports
In 2005 we initiated a project designed to better understand tree island structure and function in the Everglades and the wetlands bordering it. Focus was on the raised portions at the upstream end of the islands, where tropical hardwood species adapted to well-drained conditions usually are the most prominent component of the vegetation. The study design is hierarchical, with four levels; in general, a large number of sites is to be surveyed once for a limited set of parameters, and increasingly small sets of islands are to be sampled more intensively, more frequently, and for more aspects of ecosystem function. …
Effect Of Hydrologic Restoration On The Habitat Of The Cape Sable Seaside Sparrow, Annual Report Of 2003-2004, Michael S. Ross, Jay P. Sah, Pablo L. Ruiz, David T. Jones, Hillary Cooley, Rafael Travieso, James R. Snyder, Sara Robinson

SERC Research Reports
Following on our previous year’s work on ‘Effect of hydrologic restoration on the habitat of the Cape Sable seaside sparrow (CSSS)’, we presented first year results at the Cape Sable seaside sparrow – fire planning workshop at Everglades National Park in December 2003. Later, with almost the same set of crews as in the previous year, we started field work in the first week of January and continued till May 26, 2004. Protocols for sampling topography and vegetation in 2004 were identical to the previous year. In the early season, we completed topographic surveys along two remaining transects, B and …
Hydrologic Restoration Of The Biscayne Bay Coastal Wetlands: Mosquito And Drainage Ditch Inventory And Recommendations, Pablo L. Ruiz, Michael S. Ross
Hydrologic Restoration Of The Biscayne Bay Coastal Wetlands: Mosquito And Drainage Ditch Inventory And Recommendations, Pablo L. Ruiz, Michael S. Ross
SERC Research Reports
The management and restoration of the Biscayne Bay Coastal Wetlands (BBCW) is a complex issue. Unlike other natural areas under the supervision of the National Park System, the BBCW had endured many years of neglect and abuse by homesteaders who, prior to the establishment of Biscayne National Monument in 1968, had free reign of the area and tried to farm and develop the land by ditching and infilling. Furthermore, public works projects, dating back to the early 1900’s for mosquito control, land reclamation, and storm surge protection along with homesteader activities have combined to compartmentalize the coastal wetlands of present …

SERC Research Reports
After developing field sampling protocols and making a series of consultations with investigators involved in research in CSSS habitat, we determined that vegetationhydrology interactions within this landscape are best sampled at a combination of scales. At the finer scale, we decided to sample at 100 m intervals along transects that cross the range of habitats present, and at the coarser scale, to conduct an extensive survey of vegetation at sites of known sparrow density dispersed throughout the range of the CSSS. We initiated sampling in the first week of January 2003 and continued it through the last week of May. …
