Simulated data for prioritizing sites for ecological surveys.
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_cost column),
cost of acquiring sites for conservation (management_cost column),
results from previous ecological surveys (f1, f2, f3 columns),
previous survey effort (n1, n2, n3 columns),
environmental conditions of the sites (e1, e2 columns),
and modeled probability of the features occupying the sites
(p1, p2, p3 columns).
sim_featuresThis object describes the features and contains
the following data:
the name of each feature (name column),
whether each feature should be considered in future surveys
(survey column),
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_specificity columns),
and the representation target thresholds for each feature
(target column).
These datasets were simulated using simulate_feature_data()
and simulate_site_data().
