Eventually these industry profiles will enable customized species responses depending on types of impact.

Background. Welcome to Conservation Routing! Least cost routes are calculated based on different cost surfaces. The initial cost surface applies a constant value for all cells resulting in a Euclidean path with the minimum distance. This path would be the least costly to industry, making it the reference point (min(dist)) to which other routes are compared. Other paths are calculated by applying transformations to the conservation risk surface, which is calculated as the cumulative species score weighted by extinction risk. The summation of conservation risk values traversed by the path determines the conservation score. The reference point (min(cost)) is subtracted from all values.

More formally, each pixel ($$i$$) across $$n$$ species ($$s$$) is summed by its relative density ($$z_i$$), which is based on the pixel values' ($$x_i$$) deviation ($$\sigma_s$$) from mean density ($$\mu_s$$), and multiplying by the species' extinction risk weight ($$w_s$$): $$z_{i,s} = \frac{ x_{i,s} - \mu_s }{ \sigma_s } \\ Z_i = \frac{ \sum_{s=1}^{n} z_{i,s} * w_s }{ n }$$
