Abstract

Geomys personatus maritimus (Maritime Pocket Gopher) is a genetically distinct subspecies of pocket gopher that occurs only in deep, sandy soils located in Nueces and Kleberg counties of southern Texas. The US Fish and Wildlife Service considers it a species of concern. Pocket gophers are considered a nuisance because they dig burrows and create mounds in landscaped areas. Lethal control options are not advised because of the Maritime Pocket Gopher's rarity status and recent public attitude disfavoring lethal methods. However, short-distance translocation might be a management option, but research to determine its viability is lacking. We captured 15 Maritime Pocket Gophers from athletic fields and commercial properties in Corpus Christi, TX. For all captured gophers, we subcutaneously or intraperitoneally implanted a radio transmitter, translocated the animals to private property within 2 km from their capture site, and radio-tracked their movements for ≤⃒4 months to determine if their behavior and activity differed from 4 control gophers. Subcutaneous transmitters implanted in the scapular region were lost by 86% of the gophers (n = 12 of 14), while 100% (n = 5) of the gophers retained intraperitoneal-implanted transmitters. Relocated Maritime Pocket Gophers did not return to their site of origin. Gopher movements generally were away from their homing lines (i.e., an imaginary line drawn between each translocated gopher's capture site and release site), and they did not become successively closer to their respective sites of capture. Therefore, short-distance translocation has the potential to be a management option for nuisance gophers.
