Over the course of four years between 2009 and 2012, researchers Paul Leberg and Rebecca Davis of the University of Louisiana at Lafayette used proven spotted skunk detection methods to try to find out if eastern spotted skunks still remained in the Louisiana. Using a combination of baited track plates, remotely triggered camera traps, hair snares and live traps the researchers failed to find even a single trace of an eastern spotted skunk remaining in the state.
Declines in eastern spotted skunks across their historic range have been reported to be as high as 99%. In Louisiana, a 97% decline in eastern spotted skunks was first documented over four decades ago based on declines in statewide fur sales between the 1920's and 1960's. Now there is scientific evidence to suggest that eastern spotted skunks are very rare or perhaps extirpated from the state.
The author's failure to find even a single animal following the first systematic survey of a state at the core of their former historic range should raise further conservation concern for the future of this species. Unfortunately, with spotted skinks being so rare and on the verge of extirpation in Louisiana and elsewhere through the central, southern and eastern US, it is increasingly difficult or impossible to learn what they need to persist.
We now more than ever need the public to step forward with sighting of this species so that researchers can begin to conduct detailed studies to find out about there ecology. Only by discovering what conditions they do rely on and what impacts their survival will we be able to conserve the species effectively into the future.
