Nest
Predator Use of Food Plots Within a Forest Matrix: An Experiment Using Artificial
Nests Research Team: Dr. L Michael Conner (Associate Scientist) and Micah Perkins (Research Technician III)
Food
plots are often used to enhance wildlife habitat within forested systems,
but food plots also create edge within the forested matrix that may attract
nest predators. Because little information exists regarding how food plots
affect nest predation, we examined predation rates on artificial nests placed
in 30 food plots (0.70 – 13.0 ha). We determined that 4 landscape variables
and 1 temporal variable were important predictors of predator use of food
plots. Predators used forested edges more intensively than fallow strips within
food plots and small food plots with short perimeters more intensively than
large food plots with long perimeters. As food plots became more irregularly
shaped, intensity of predator use increased. Lastly, predators used food plots
more intensively during the early nesting season (May) than during the later
nesting season (July). Because many bird species nest along food plot/forest
ecotones or in native vegetation within periodically disturbed sites, managers
should consider food plot designs which reduce encounter rates between nesting
birds and their predators.
