DASCO workflow for downscaling alien species checklists using occurrence records

View as: JSON-LD

The DASCO workflow has been designed to integrate regional checklists of alien species occurrences and occurrence records provided by GBIF and OBIS to identify coordinate-based occurrences of alien populations. It can therefore be used to downscale information available in regional checklists and to re-allocate species occurrences to any spatial categorisation, which is provided by the user.

The DASCO workflow is written in R and open access. The workflow is described together with a global case study  in a peer-reviewed publication (see below) together with a manual.

When using any components of the workflow, please cite the following publication:
