Nancy Peterson, Program Coordinator This publication was produced by The Center for Natural Resources (CNR). Established in 1973, CNR at the University of Florida plays a major role in the conservation, preservation and restoration of our nation's natural resources by facilitating interdisciplinary collaborations between UF faculty and external stakeholders.

Florida Cooperative Extension Service/Institute of Food and Agricultural Sciences/University of Florida/Christine Taylor Waddill, Dean. The MacArthur Agro-Ecology (MAERC) project investigates the relationships between cattle ranching, citrus production and Florida native ecosystems. Researching the complex issues surrounding natural resource management in an agricultural environment, program participants hope to develop protective strategies of Florida natural resources while still maintaining economically viable and compatible agricultural industries within the state. Particularly important is understanding how cattle (Figure 1) and citrus production affect water quality and soil nutrients, and how these factors influence invertebrate and wildlife populations. Figure 1. Cattle at MAERC. Project Goals Understanding the ranch ecosystem and landscape of Central Florida including water quality, nutrient flow, wetland dynamics, and population biology of native and exotic species. Measuring the effects of selected low-input agricultural practices on long-term health and sustainability of the ranch ecosystem and the economic implications of implementing these practices. Cooperating between all community stakeholders to promote natural resource conservation within the context of a viable agricultural economy.

Research focuses on types of nematodes (herbivores, bacterivores), their prevalence, and their dependence on organic matter from varying cattle populations.

The MacArthur Agro-Ecology Program at Buck Island 3 Economics A successful link between modeling and SPA-like (Standardized Performance Analysis) databases requires collaborative fact-finding and sharing among ranchers. The resulting database could more clearly chart management strategies and their outcomes.

The influences of burning, mowing, and cattle-grazing practices are also studied via soil samples. Jeff Mullahey West Florida REC Jay jjm@ifas.ufl.edu 684-3780 SUNCOM Jay 850-994-5215 Wildlife Frogs and wetland invertebrates are essential to the ranch wildlife food web. Land management for cattle grazing (such as ditch-construction and draining) are planned to accommodate the various split-development needs of different species of frogs and invertebrates. Buck Island Ranch attracts many migratory and nesting birds (Figure 3) -as many as 46 bird species in the summer and 54 in the winter. Figure 3. The crested caracara is a threatened raptor/scavenger found in Florida almost exclusively on cattle ranches. Researchers have radio-tagged and monitored the development of nine caracara families on MAERC. George Tanner Wildlife Ecology & Conservation Department tannerg@wec.ufl.edu 352-846-0552
