TL;DR: This article defined African savannahs as being those areas that receive between 300 and 1,500mm of rain annually and defined lion areas as places that likely have resident lion populations using high-resolution satellite imagery and human population density data.

TL;DR: It is demonstrated that when habitat fragmentation is considered in addition to habitat loss, the world’s species, ecosystems and associated services are in worse condition than previously reported.

TL;DR: A new tool, GE Grids, which creates an interactive user-specified binary grid laid over Google Earth's high-resolution imagery, intended to complement existing remote sensing datasets at local scales.

TL;DR: It is suggested that about half of Earth's terrestrial surface has relatively low human influence and offers opportunities for proactive conservation actions to retain the last intact ecosystems on the planet.

TL;DR: In this article, the authors document the extent to which East African protected areas encompass ecoregions and endemic terrestrial vertebrate taxa, and using new land conversion data derived from medium to high spatial resolution satellite images, assess how they have been encroached upon by agriculture and other land use.
