In dcarver1/gapAnalysisR: An R package to calculate conservation indicators using species distribution models

Description

Performs an estimation of germplasm representativeness score for in-situ gap analysis (GRSin) using Khoury et al., (2019) methodology This function uses a germplasm buffer raster file (e.g. CA50), a thresholded species distribution model, and a raster file of protected areas

ERSin = min(100,(Number of ecoregions where germplasm accessions in protected areas/ Number of ecoregions where species distribution is intersected with protected areas)*100)

Usage

ers_insitu(species, Workspace, run_version)

Arguments

species	A name species compiled using '_' to call the raster files (SDM and germplasm buffer) from Workspace/parameters/inputs folder and occurrences files from Workspace/parameter/occurrences folder
Workspace	A forder where the pipeline will be executed
run_version	The version of the analysis used (e.g 'v1')

Value

It returns a raster file with the species distribution model restricted to the protected areas raster file provided. Also, this function returns a data frame file saved at gap_analysis folder with four columns:

ID	Species name
SPP_N_ECO	Number of ecosystems where species distribution model is within protected areas
SPP_WITHIN_PA_N_ECO	Number of ecosystems where germplasm accessions are within protected areas
ERS	ERSex result
