Occupying no more than a 30- mile stretch of creek, its survival is highly dependent upon the actions of those living in communities surrounding their homerange. Currently, promising conservation programs work to involve the community in restoring habitat that has been degraded by agricultural runoff, siltation, and the introduction of invasive species. #crayfish #Nashville #Tennessee #animal #wildlife #photography #animalphotography #wildlifephotography #endangered #stamp #PhotoArk @insidenatgeo @uspostalservice」5月3日 20時54分
