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
Brilliant arboreal alligator lizard in protected areas such as Mario Dary Rivera Protected Biotope and Sierra de las Minas Biosphere Reserve. Brilliant arboreal alligator lizard The brilliant arboreal alligator lizard (Abronia gaiophantasma) is a species of lizard endemic to the mountains of east-central Guatemala, from the Sierra de las Minas east to the Chilascó region. It occurs at elevations of 1,600–2,650 m, and can be found in pine–oak and cloud forests of lower montane wet forests. Its extent of occurrence is estimated at only 750 km, and has been declared endangered. Threats to this species include habitat loss from agriculture, and the exportation of
