This layer quantifies the impact humans have had on the intactness of species communities. Anthropogenic pressures such as land use conversion have caused dramatic changes to the composition of species communities and this layer illustrates these changes by focusing on the impact of forest change on biodiversity intactness. The maximum value indicates no human impact, while lower values indicate that intactness has been reduced. The [PREDICTS database](https://www.nhm.ac.uk/our-science/our-work/biodiversity/predicts.html) comprises over 3 million records of geographically and taxonomically representative data of land use impacts to local biodiversity (Hudson et al. 2017). A subset of the PREDICTS database, including data pertaining to forested biomes only, is employed to model the impacts of land use change and human population density on the intactness of local species communities. To produce the land use map, all forested biomes are selected and each 30 x 30 m pixel within the biome is assigned a land use category based upon inputs from the GFW forest change database and a downscaled land use map (Hoskins et al 2016). The modelled results of biodiversity intactness derived from the PREDICTS database are projected onto the land use and human population density maps, and the final product is aggregated to match the resolution of the downscaled land use map (Hoskins et al 2016). The final output models the impacts of forest change on local biodiversity intactness within forested biomes.

Displays the impacts of forest change on local biodiversity intactness

1. The metric assumes that the biodiversity found in a perfectly intact site is equivalent to the biodiversity that would be present without human interference<br>2. Human impacts on biodiversity intactness are quantified through models that extrapolate results from site-specific studies across large areas and there is always a degree of uncertainty in such extrapolations<br>3. Plantation forests were not distinguished from natural forests in this analysis, and as such, plantation areas may be counted as intact biodiversity areas. <br>
