The basis of the IUCN Red List of Ecosystems are the IUCN Red List of Ecosystems Categories and Criteria, a set of eight categories and five criteria that provide a consistent method for assessing an ecosystem's risk of collapse. They are designed to be: broadly applicable across type ecosystems and geographic areas, transparent and ...
Management categories and governance types are independent and can be juxtaposed in the “IUCN Matrix”, [9] [10] visualizing a spectrum of area-based options to conserve nature in a given region/system. The IUCN Matrix can be used to situate protected areas but also conserved territories and areas (the management category, in such case ...
A wilderness area (IUCN Category Ib) is similar to a strict nature reserve, but generally larger and protected in a slightly less stringent manner.. These areas are a protected domain in which biodiversity and ecosystem processes (including evolution) are allowed to flourish or experience restoration if previously disturbed by human activity.
IUCN co-drafted the World Heritage Convention with UNESCO and has been involved as the official Advisory Body on nature from the onset. [8] CITES – the Convention on International Trade in Endangered Species of Wild Fauna and Flora (1974). IUCN is a signatory party and the CITES secretariat was originally lodged with IUCN.
The IUCN protected area categories are: IUCN Category Ia — Strict Nature Reserve; IUCN Category Ib — Wilderness Area; IUCN Category II — National Park; IUCN Category III — Natural Monument or Natural Feature; IUCN Category IV — Habitat management area / Species Management Area; IUCN Category V — Protected Landscape / Protected Seascape
Of the 670 ecoregions with forest cover, 54% have 10% or more of their forest cover protected under IUCN Categories I – VI. [ 19 ] Mountains: Nationally designated protected areas cover 14.3% of the world's mountain areas, and these mountainous protected areas made up 32.5% of the world's total terrestrial protected area coverage in 2009.
An example of an ecosystem service is pollination, here by a honey bee on avocado crop.. Ecosystem services are the various benefits that humans derive from ecosystems.The interconnected living and non-living components of the natural environment offer benefits such as pollination of crops, clean air and water, decomposition of wastes, and flood control.
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
