ConR

ConR computes species' extent of occurrence (EOO), area of occupancy (AOO), and estimates number of locations to produce preliminary IUCN Red List Criterion B conservation assessments from georeferenced occurrence data.

Key Features:

• R package implementation: Implemented in R to perform large-scale, automated conservation assessments.
• Geographical Range Parameter Calculation: Calculates EOO, AOO, and estimates number of locations as required under IUCN Criterion B.
• Automated Batch Processing: Processes multiple species simultaneously to generate preliminary assessments in batch.
• Data Summarization and Visualization: Outputs results in spreadsheets and generates maps to support IUCN Red List submissions.
• Taxonomic Versatility: Applies to any organism with reliable georeferenced distribution data across diverse taxa.

Scientific Applications:

• Preliminary IUCN assessments: Produces Criterion B-based preliminary conservation status assessments for species using occurrence data.
• Conservation prioritization: Identifies species with restricted EOO/AOO or limited locations that may require urgent conservation attention.
• Large-scale analyses with open datasets: Enables automated processing of large open-access occurrence datasets for multi-species range estimation.

Methodology:

ConR uses georeferenced distribution data to compute EOO, AOO, and number of locations according to IUCN definitions, performs these computations in batch, and exports results as spreadsheets and maps.
