Simulated data for prioritizing sites for ecological surveys.
Details
The simulated datasets provide data for six sites and three features. The sites can potentially acquired for protected area establishment. However, existing information on the spatial distribution of the features is incomplete. Only some of the sites have existing ecological survey data. To help inform management decisions, species distribution models have been fitted to predict the probability of each species occupying each site.
sim_sitesThis object describes the sites and contains the following data: cost of surveying the sites (
survey_costcolumn), cost of acquiring sites for conservation (management_costcolumn), results from previous ecological surveys (f1,f2,f3columns), previous survey effort (n1,n2,n3columns), environmental conditions of the sites (e1,e2columns), and modeled probability of the features occupying the sites (p1,p2,p3columns).sim_featuresThis object describes the features and contains the following data: the name of each feature (
namecolumn), whether each feature should be considered in future surveys (surveycolumn), the sensitivity and specificity of the survey methodology for each the sensitivity and specificity of the species distribution model for each feature (model_sensitivity,model_specificitycolumns), and the representation target thresholds for each feature (targetcolumn).
