2021_HPAI_AvianHost_DistributionIndices

Weighted Index and formatted distribution data for HPAI hosts. 

Abstract:

A series of descriptive metrics were produced as host distribution indices for use as covariates in HPAI spatial modelling. The following bird species were included. For each, disptribution maps were extracted from the Birdlife International datasets and idvidual ratster images were produced for breeding, passage, resident and passage distributions.  Anas crecca, Anas penelope, Anal platyrhynchos, Anser anser, Aytha fuligula, Bucephala clangula, Cygnus color, Cygnus cygnus, Mareca penelope, Mareca strepera,  Combination images for all species were also produced , each giving the number of species per pixel for each category ( Anatidae passage, Anatidae breeding, Anatidae resident, Anatidae nonbreeding,.

File naming scheme: 

Filenames = AIHOSTxxxxsum.tif where XXX = breeding, nobreeding, resident, passage)
