Abstract:
The recent colonization of Everglades National Park and adjacent areas by Burmese pythons (Python molurus bivittatus) has created significant new challenges for restoration of this world-renowned ecosystem. Not only are the hydrologic techniques traditionally applied to restoration of the Everglades insufficient for controlling this new threat, but snake management is an underdeveloped specialty that has been elaborated only for two comparatively-small terrestrial/arboreal snakes, the Brown Treesnake on Guam and the Habu in the Ryukyu Islands. Like the python, these snakes have the potential to threaten human health and seriously disrupt natural ecological processes. In the case of Guam, the snake's introduction resulted in a catastrophic loss of biodiversity. The control techniques developed for those island snakes (traps, searches, dog-aided searches, habitat modifications, prey base control, and toxicants) may be applied to Burmese pythons in the Everglades. However, modifications to accomodate the unique wetland character of the Everglades and the suite of nontarget species present in south Florida's reptile-rich continental environment will be necessary. Other modifications are ndeede dto optimize control effectiveness by matching control tool application to behavior, morphology, and ecology of Python molurus. For example, effective placement and spacing of traps must accomodate habitat use, size, and movement rates the of python. In this project, we will continue the highest priority task outlined in a 2005 workshop of invasive snake management experts (July 2005 - Invasive Snake/Reptiles Management and Response Workshop, West Palm Beach, Florida): conducting strategic field studies of python life history. In particular, we will continue collecting location dta for radio-tracked pythons with a focus on microhabitat selection in the breeding season (i.i., spring 2010). This information is critical for understanding the potential impacts of pythons on the Greater Everglades ecosystem. This activity will benefit the Greater Everglades (i.e., Everglades National Park, but also vulnerable conservation areas throughout southern Florida (e.g., Big Cypress National Preserve, water conservation areas (WCAs)), the remainder of the Florida peninsula, and coastal southeastern U.S.).
Purpose:
The purpose of this project is to provide science support to determine the overlap of python movements and home ranges on native biological diversity and develop control measures for Burmese pythons. The specific objectives of this project are to:
1) Synthesize results on natural history of pythons in an adaptive framework to evaluate relationships between ecosystem restoration and habitat modification on control of pythons.
2) Synthesize results on natural history of pythons to provide an assessment of the impacts of pythons on native species, as determined through radiotelemetry.
3) Develop spatially-explicit habitat suitability indices (using 3 years of radiotelemetry data for individual snakes) to evaluate Everglades restoration alternatives on the spread and establishment of pythons

Process_Description:
Task Summary and Objectives: We have taken advantage of the best available scientific information and technical experience from experts to design a science support program for eradication of pythons. It is essential to continuously synthesize incoming information from experiments and monitoring and apply it to modify control and containment actions. For example, diet data from trapped pythons can be used to modify trapping procedures; radiotelemetry data on spatial and temporal habitat use patterns will feedback into determining where and when to trap pythons. Furthermore, natural history data such as diet analysis will be used to evaluate impacts of pythons on native species and habitat, and movement data will also be applied to developing an understanding of habitat suitability. Such information allows us to prescribe management recommendations such as mowing berms to reduce suitability of habitat for pythons. All python data can be used to create a spatially-explicit, regional habitat-suitability model that can be used to evaluate impacts of ecosystem restoration alternatives on establishment and spread of pythons. Continuously synthesizing and integrating data into the containment and control program will provide an adaptive management approach to eradication of pythons.

Work to be undertaken during the proposal year and a description of the methods and procedures: Python radio-tracking data will be summarized using standard home-range metrics (i.e., minimum convex polygon (MCP) and kernel density estimation (KDE) procedures). Spatial data will further be used to create a spatially-explicit habitat-suitability model that can be used to evaluate impacts of ecosystem restoration alternatives on establishment and spread of pythons. We are also evaluating the potential for satellite and GPS tags to work in Burmese pythons, which may provide us with daily location data.
