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
Brazilian arboreal mouse found in four other localities in Brazil, near Ubatuba in São Paulo State, including in Pincinguaba State Park, and near Viçosa in Minas Gerais State. It typically lives in Atlantic forest, often among bamboos, and also in modified forest habitats. Little is known about this species and its natural history. Several specimens were caught in pitfall traps sunk in the ground, but it is thought that it is an arboreal rodent, or one that scrambles among the undergrowth, because of the morphology of its feet. Examination of the stomach contents of one individual that was caught showed that it had
