Space for Nature

Posted in All Articles, News & Publications on 09/19/18

Space for Nature   How much of the planet should we leave for other forms of life? This is a question humanity must now grapple with. The global human population is 7.6 billion and anticipated to increase to around 10 billion by the middle of the century. Consumption is also projected to increase, with demands for food and water more than doubling by 2050. Simply put, there is finite space...

How to Protect Half

Posted in All Articles, News & Publications, Papers & Publications on 08/30/18

How to protect half of Earth to ensure it protects sufficient biodiversity   Abstract   It is theoretically possible to protect large fractions of species in relatively small regions. For plants, 85% of species occur entirely within just over a third of the Earth’s land surface, carefully optimized to maximize the species captured. Well-known vertebrate taxa show similar patterns. Protecting half of Earth might not be necessary, but would it...

Connectivity: the safety network for biodiversity conservation

Posted in All Articles, Blog on 07/27/18

  August 1st, 2018 Article by Gary Tabor, Center For Large Landscape Conservation Across the globe, wildlife have less freedom to roam.  In an increasingly fragmented world where nature is segmented, land mammals are moving two to three times less.  With limited ability to migrate, to disperse, to mate, to feed and to thrive, wild animals are cornered into situations where the threat of extinction looms greater (Tucker et al....

Some scientists say it is. In a paper published last week in the journal Nature Ecology and Evolution, a team of Australian researchers argue that we need to shift conservation goals to focus on diverse and ambitious “nature retention targets” if...
