Use fencing to exclude predators or other problematic species Terrestrial Mammal Conservation

A replicated, controlled study in 2005–2009 in four woodland sites in Georgia, USA (Karmacharya et al. 2013) found that using fencing to exclude predators did not increase survival of southern flying squirrels Glaucomys volans. Monthly survival rates for squirrels was similar in areas that were fenced to exclude predators and areas that were not fenced (data reported as model results). Four plots were fenced with a 1.2-m tall, electrified, fence while four plots were not fenced. Plots were 36–49 ha. One-hundred and forty-four traps baited with oats and bird feed were placed on the ground in each plot and 24 traps were placed in trees. Between January 2005 and June 2007, trapping was carried out four times a year and, in July 2007–September 2009, trapping was carried out eight times a year. Trapping was conducted over four consecutive nights. Animals caught were marked with ear tags.
