SPECIES DISTRIBUTION & HABITAT SUITABILITY
Habitat suitability maps for 94 boreal-breeding passerine species.
Habitat suitability maps
Maps depict model-predicted species distribution and provide information about relative habitat suitability based on current climate and landcover. The suitability ranking of any mapped grid cell is the sum of the probabilities of that grid cell and all other grid cells with equal or lower probability, multiplied by 100 to give a percentage. This value represents the % of grid cells with a lower suitability value within the boreal/hemiboreal study region. Higher value pixels represent higher habitat suitability for a given species. The maximum entropy (Maxent) method was used to develop species distribution models (SDM) for passerine species during the breeding season. Maxent is a powerful machine-learning algorithm with demonstrated high predictive accuracy compared to other SDM methods.
