Depletion of biodiversity was defined as a decrease in species and habitat intactness, which\naffects the delivery of ecosystem services such as pollination and mass stabilisation, as well\nas recreation and tourism. <\/p>

The Biodiversity Intactness Index (BII), by Newbold et al. (2016)<\/a>, was determined to be a\nsuitable indicator of depletion of biodiversity. The BII is a modelled average abundance of\noriginally present species (species found in such an ecosystem in an intact state), relative to\ntheir abundance in an intact ecosystem (a pristine baseline). It models changes in the\nabundance and composition of ecological communities in response to a range of pressures,\nincluding land use change. It therefore reflects elements of habitat quantity and quality. The\nBII layer does not reflect recent change (unlike the other asset datasets used in the analysis)\nas intactness is modelled in comparison to fully intact natural habitat. A global layer depicting\nchange in the BII (declines in the level of intactness compared to a fixed point in time) is in\ndevelopment, but not yet available. Eventually, this layer may distinguish areas where habitat\nloss is currently occurring from areas where habitat was lost historically. <\/p>

Large hotspots of biodiversity depletion (which correspond to the top\n20% of relative depletion values) were found in the Great Plains in North America, the\nSouthern cone of South America, Southern Africa, Central Asia, and Australia. The\noverlap of hotspots of biodiversity depletion with terrestrial biomes are detailed in Annex 2<\/a>. <\/p>

Temperate Grasslands, Savannas and Shrublands had the greatest overlap (70%) with\nhotspots of depletion, whereas Boreal Forests and Taiga, and Tundra had close to no overlap. <\/p><\/div>", "summary": "Depletion of biodiversity was defined as a decrease in species and habitat intactness, which\naffects the delivery of ecosystem services such as pollination and mass stabilisation, as well\nas recreation and tourism.", "title": "Global relative rate of natural capital depletion of biodiversity", "tags": [ "natural-capital", "habitats-and-biotopes", "species-distribution", "ckp:theme=nature-economy", "ckp:license=cc-by-sa", "ckp:theme=nature-conserved", "ckp:theme=nature-restored", "ckp:theme=science", "ckp:proteus=available" ], "type": "Image Service", "typeKeywords": [ "Data", "Service", "Image Service", "ArcGIS Server" ], "thumbnail": "", "url": "https://data-gis.unep-wcmc.org/server", "minScale": 2.95828763795855E8, "maxScale": 4622324.43431023, "spatialReference": "GCS_WGS_1984", "accessInformation": "UNEP-WCMC.
