Overview
BioDispersal is a QGIS 3 plugin.
Its purpose is to compute ecological continuities based on environments permeability and animals potential dispersal areas. BioDispersal has been designed as a 7-steps plugin from raw data preprocessing to the final dispersal areas computation. Parameters settings can be saved to and loaded from a configuration file.
Below is an example of dispersal map created by BioDispersal:
BioDispersal has been developped by UMR TETIS - IRSTEA, on mission for the French ecological network resource center (driven by French ministry of ecology).

Installation
BioDispersal requires QGIS 3.4 (or superior version) and GRASS.
Go to plugins menu, Install/manage plugins, type BioDispersal and click on Install button. A dear icon should appear. Otherwise, it is available in plugins menu.

Sample data
Sample data is provided with plugin (directory sample_data/BousquetOrb).
To produce above dispersal map, open configuration file BousquetOrb.xml and run steps 3,4,5,6,7.
Steps
BioDispersal is a 7 steps plugin:
- Parameters setting
- Subnetworks definition
- Selection and classification from input data
- Data ranking to obtain a complete land use layer for each subnetwork
- Friction coefficients definition to obtain a permeability layer for each subnetwork
- Weighting of permeability layers if needed (optional step)
- Dispersal areas computation
Each step is detailed in plugin help panel.
