distribution models applied to conservation of Andalusia

recently from the Department of Geodiversity and Biodiversity of the Ministry of Environment of the Junta de Andalucía and EGMASA I commissioned the project "Flora Distribution Models for assisting decision making in conservation plans."

The project objective is to obtain distribution patterns of high-resolution (40 meters) to assist in defining the areas of activity of 108 species of threatened flora of the following conservation plans:
  • Reintroduction Plan, Conservation and Management Flora of Altas Cumbres.
  • Conservation and Recovery Plan of Petridófitos
  • Conservation and Recovery Plan Plants Dunes, Coastal and Litoral Arenales
The Flora Conservation Department gave us the necessary information on the distribution of species (from the FAME; Flora Threatened Andalucía). With presence records (a total of 43,912) calibrate models using MaxEnt, using 55 predictor variables (topography, climate, hydrology, thematic layers, frequencies and distances to various entities, and Landsat bands). As a result, for each species got:
  • A model Distribution: raster map where each cell contains the probability 40x40 presence of the species.
  • A vector file of potential presence of the species: a summary of the previous model, and defines the areas of highest probability of presence.
Of the 108 species models got 89, which classified them into three groups:
  • Applicable: 53 models appropriate for the project.
  • Caution: 20 models to be applied carefully, because they have achieved a good fit, either by the low number of presences or for other reasons. Discard
  • : 16 models is better or looking through a very bad fit. Last 17
February, with work already completed, I met with the leaders to show the results and deliver the material, and things went pretty well (at least so it seemed!). I thank you from here their interest and involvement (and hold my talk for two hours), Fernando Ortega Alegre, Carmen Rodriguez Hiraldo, José Rafael López and Antonio Garrido J. Sanchez Almendros

I am particularly pleased with the project because it is the first time that distribution models are applied to the management of threatened flora in Spain. I am happy to contribute if only indirectly on the conservation of our flora, and especially using a tool that come trusting several years.

That's it!
