Protected areas are key to biodiversity conservation. While the value of protected areas is generally undisputed, challenges remain. Many areas designated as protected were created for
objectives other than biodiversity conservation, and those objectives can conflict with biodiversity
conservation. Protected area legal status is, in many cases, impermanent. Protected areas are
generally too small, isolated, and few to conserve biodiversity on their own, and thus there are calls
for connected conservation areas between them, and for their integration into broader landscapes
and seascapes [1]. There is a general consensus that the current global suite of protected areas is
insufficient to protect biodiversity. Although there is no precise prescription for how much would be enough, systematic conservation planning studies have indicated that 25–75% of a region is required to capture key elements of biodiversity [2]. Studies that address range shifts and movement pathways in response to climate change reveal even more extensive area and connectivity requirements. These and other insights have contributed to recent calls for ‘half Earth’Call Number: [EL]ISBN/ISSN: 978-3-03897-732-2,978-3-03897-733-9Physical Description: 200 p.
