Habitat species and old growth trees are more vulnerable to logging as access is improved. The birds that nest in their crevices, the epiphytes that hang from their branches and the invertebrates in the leaf litter are all adversely affected and biodiversity is reduced. Habitat fragmentation can be ameliorated to some extent by the provision of wildlife corridors connecting the fragments. These can be a river, ditch, strip of trees, hedgerow or even an underpass to a highway. Without the corridors, seeds cannot disperse and animals, especially small ones, cannot travel through the hostile territory, putting populations at greater risk of
Long-tongued arboreal mouse because of its tolerance of several types of habitats, and because in the absence of any particular threats, it seems unlikely that it is declining at a sufficient rate to qualify for being included in a more threatened category. Long-tongued arboreal mouse The long-tongued arboreal mouse ("Rhagomys longilingua") is a South American rodent species of the family Cricetidae. It is found in a variety of habitats, including dense forest, in Bolivia and Peru at elevations from on the eastern side of the Andes. The species is at least partly arboreal. It is distinguished from the Brazilian arboreal mouse ("R. rufescens"),
