Land Corridors
Areas of land that serve to connect two or more wildlife areas. These are often narrow strips of land and can include small pockets of habitat or microrefugia.
Animating the Carbon Cycle
Climate change is commonly viewed as causing collateral damage to biodiversity. Wildlife species, particularly animals, are widely perceived as unwitting victims - passengers trapped aboard a ship on an ill-fated voyage. In reality, animals play a critical role in determining the course of the climate ship. From elephants to grasshoppers, sharks to sea otters, species of all descriptions, habitats, and climate zones impact global carbon exchange in different ways. Within a complex web of interactions, some have a greater impact than others, while the impact of the same species may vary from ecosystem to ecosystem. This report provides 10 case studies that showcase the diversity and complexity of the relationship between animals and the global carbon cycle, both in terrestrial and marine environments. They also demonstrate just how important it is to protect and restore wildlife populations as we look to address climate change.
An ecoregion-based approach to restoring the world's intact large mammal assemblages
Assemblages of large mammal species play a disproportionate role in the structure and composition of natural habitats. Loss of these assemblages destabilizes natural systems, while their recovery can restore ecological integrity. Here we take an ecoregion-based approach to identify landscapes that retain their historically present large mammal assemblages, and map ecoregions where reintroduction of 1–3 species could restore intact assemblages. Intact mammal assemblages occur across more than one-third of the 730 terrestrial ecoregions where large mammals were historically present, and 22% of these ecoregions retain complete assemblages across > 20% of the ecoregion area. Twenty species, if reintroduced or allowed to recolonize through improved connectivity, can increase the area of the world containing intact large mammal assemblages by 54% (11 116 000 km2). Each of these species have at least two large, intact habitat areas (> 10 000 km2) in a given ecoregion. Timely integration of recovery efforts for large mammals strengthens area-based targets being considered under the Convention on Biological Diversity.
