BioDispersal is a QGIS plugin that allows you to model ecological continuities by calculating
potential dispersion areas based on the permeability of environments.


BioDispersal is a QGIS 3 plugin 3


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).

BioDispersal - 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.

BioDispersal - Steps


BioDispersal is a 7 steps plugin :

    1. Parameters setting
    2. Subnetworks definition
    3. Selection and classification from input data
    4. Data ranking to obtain a complete land use layer for each subnetwork
    5. Friction coefficients definition to obtain a permeability layer for each subnetwork
    6. Weighting of permeability layers if needed (optional step)
    7. Dispersal areas computation

Each step is detailed in plugin help panel.
