Project Title: Monitoring for Rasberry Crazy Ants in a bottomland forest

Project Description:
(Up to 250 words)
The objective of the agreement is to enable Gulf Coast Bird Observatory to conduct wildlife monitoring in a bottomland hardwood forest unit less than 1 mile from an infestation of Rasberry Crazy Ant (Paratrechina spp. near pubescens). This ant is believed to have reached Texas through the Port of Houston in 2002. Since then it has spread at a rate much faster than the Red Imported Fire Ant (Solenopsis invicta). This highly aggressive ant is of concern to entomologists in Texas for its potential to exert residential, agricultural, and wildlife impacts of a large magnitude. Anecdotal observation indicates that these ants drive wildlife from their vicinity due to their sheer numbers and ability to consume any reasonably stationary animal life. However, no firm documentation exists of these impacts to wildlife, with pre- and post infestation variables. Until such documentation is done, no research relevant to treatment in wildlife habitats will be funded, and no means of combating an infestation of wildlife habitat will be available. The Brazos River Unit (BRU) of San Bernard National Wildlife Refuge is ideal for wildlife monitoring pre-infestation. It is located 1.1 miles northeast of a crazy ant colony in East Columbia, TX. As expected expansion of this colony is north and east of its present location, BRU will be infested in the upcoming years if some unforeseen factor does not preclude ant expansion. Base data on nesting bird productivity will be highly beneficial in assessing ant impacts to the breeding birds of the Columbia bottomlands region of the Texas Coast. This project will also utilize data from a volunteer bird banding effort to determine expected encounters of various breeding birds in the unit while in an uninfested state.
