salt_data | R Documentation |
Conservation planning dataset for Salt Spring Island, Canada. It was obtained as part of an online Marxan-based planning tool created for the Coastal Douglas-fir Conservation Partnership (CDFCP; Schuster et al. 2017).

The following functions are provided to import data:
get_salt_pu()
Import planning unit data.
The planning units are a single layer terra::rast()
object.
Cell values denote the monetary cost of acquiring different areas
(e.g., a value of 1 = $100,000 CAD; BC Land Assessment
2015).
get_salt_features()
Import biodiversity feature data.
The feature data are a multi-layer
terra::rast()
object object.
It contains the spatial distribution of four key ecological communities.
Each layer represents a different community type.
These classes are (i) old forest, (ii) savanna, (iii) wetland,
and (iv) shrub. For each layer, values indicate the
composite probability of encountering the suite of bird species most
commonly associated with that community type.
get_salt_con()
Import connectivity data.
The connectivity data are a single-layer
terra::rast()
object.
It contains the inverse probability of occurrence of human
commensal species.
Based on the assumption that human modified areas
impede connectivity for native fauna, cells with higher values
have higher connectivity.
