For a full description of the species modeling process see the documentation. Both LC and Climate Refugia are based on 2010 landcover but differ in the climate suitability in LC the climate suitability is derived from 2010 climate variables while climate refugia is based on 2080 climate, while limiting the extent of the species to areas where the climate was suitable in 2010. They have a theoretical range from 0 to 1 but in practice the maximum values are usually below 1. Both of these datasets are indices of the ability of the landscape and climate to support populations of the species. These statistics are based on Designing Sustainable Landscapes (DSL) models of 2010 Landscape Capability (LC) and 2080 Climate Refugia. Since these metrics are a sum of the park’s ability to support the species bigger parks have an inherent advantage. Higher values for a park indicate ability to support larger populations now (LC HA) or in the future (Refugia HA). For example 1 LC HA are present on 10 hectares that each have an LC of 0.1. These are indices of the ability of the park (and buffer) to support populations of the species. The underlying link leads to a map of the 2010 LC for the species at the park. Higher values indicate greater expected density of the species in the park currently. LC score, this is calculated in the same manner as the refugia score but from LC.
The number is a link to a map of the 2080 Climate Refugia for the species in the park and buffer. Since it’s a relative density this static really reflects the quality of the park independent of it’s size. Higher values indicate greater concentration of climate refugia for the species within the park a five for instance would mean that the park has 5 times the region average refugia capability for the species. A value of 1 indicates that the park has (on average) the average value for the region. In particular it is how well the climate refugia for the species is represented in the park relative to the average climate refugia value for that species in the region as a whole. Refugia score, This score that reflects the density of refugia for a species in a given park. Each species is a link to the documentation for that species. They are ordered based on decreasing refugia scores. Species This is the species model that statistics on the row apply to.
