Biodiversity impact assessment considering land use intensities and fragmentation

The data provide supplementary information for the paper entitled "Biodiversity impact assessment considering land use intensities and fragmentation".

Coverage of the characterization factors

5 species groups: plants, amphibians, birds, mammals, and reptiles
5 broad land use types: cropland, pasture, plantations, managed forests, and urban areas
3 land use intensities: minimal, light, intense (sometimes, intensity levels had to be merged because the data did not allow to differentiate between them)
825 terrestrial ecoregions of the world (according to WWF / Olson et al. 2001)

Files
Main data

CF.csv: characterization factors (CFs) for ecoregions and 5 species groups
Taxonomically aggregated data

CF_kingdom.csv: CFs aggregated from 5 species groups to plant and animal kingdoms
CF_domain.csv: CFs aggregated from plant and animal kingdoms to the domain of Eukaryota
Spatially aggregated data

CF_country.csv: CFs aggregated from ecoregions to countries
CF_global.csv: CFs aggregated from ecoregions to the globe
Taxonomically and spatially aggregated data

CF_kingdom_country.csv: CFs aggregated to countries and plant and animal kingdoms
CF_domain_country.csv: CFs aggregated to countries and the domain of Eukaryota
CF_kingdom_global.csv: CFs aggregated to the globe and plant and animal kingdoms
CF_domain_global.csv: CFs aggregated to the globe and the domain of Eukaryota

Units
CFs for land occupation: PDF/m2
CFs for land transformation: PDF⋅yr/m2

Columns

realm: 2-letter code to identify one of 8 biogeographical realms
biome: ID to identify one of 14 biomes
eco_id: ID to identify the ecoregion, combining numbers for the realm, biome, and ecoregion within each biome nested within each realm
eco_name: ecoregion name
species_group: species group
kingdom: kingdom as a taxonomic rank
habitat_id: ID to link to the land use type and intensity as used in land_use.tif. An ID with .5 represents a merged land use class considering the two habitats with the IDs when rounding the value both up and down.
habitat: land use type and intensity
CF_*: characterization factor
*_occ*: land occupation
*_tra*: land transformation
*_avg*: average approach
*_mar*: marginal approach
*_reg: regional relative species loss
*_glo: global relative species loss
*_rsd: relative standard deviation as a measure of spatial uncertainty due to aggregation (only concerns country and globally aggregated CFs)
quality_*: data quality, distinguishing between original estimates and the use of proxies
objectid: object id of the country
iso3cd: iso3 code of the country
romnam: romanized name of the country
m49code: M49 code of the country, a standard code used by the United Nations
weighting: aspect based on which the CFs were weighted (only concerns globally aggregated CFs)

Data quality

original: original estimate (for globally aggregated CFs: mostly original estimates, proxies only considered in areas with current land use)
proxy_intensity: intensity level was missing; CF was derived from another CF of the same ecoregion and land use type but different intensity level and scaled to the right intensity level
proxy_type: land use type was missing; CF was derived from the average regional CFs for light use in the same biome and the ecoregion-specific GEP and scaled to the right intensity level if needed
proxy_gep: global extinction probability (GEP) was missing (only concerns CFs for global relative species loss); GEP estimated based on average GEP per area unit in the same biome and the ecoregion area
proxy_partial: some species groups were missing but not all (only concerns taxonomically aggregated CFs); aggregation done based on partly original estimates and partly proxies
proxy_neighbours: country was missing (only concerns country-aggregated CFs); values were estimated based on the average of the three nearest neighbouring countries
proxy: proxies were considered even in areas without current land use (only concerns globally aggregated CFs)
Note: proxies in country-aggregated CFs apply to at least one of the ecoregions overlapping with the country and not necessarily all ecoregions
