AB We investigated the existence of chorotypes – assemblages of species with similargeographical ranges – of invasive species in a host territory, and their potential use toadvocate similar control or management strategies for species in the same chorotype. We analysed the distribution of 13 exotic terrestrial vertebrate species (sixbirds, six mammals, and one reptile) with well-known distributions in mainlandSpain. We used the presence/absence data on a grid of 10 km × 10 km UTM cellsfrom the Atlases of terrestrial vertebrates of Spain. These data were aggregated to agrid of 50 km × 50 km UTM cells, because it entailed no loss of meaningful information and allowed dealing with a much lower number of cells. Using cluster analysisand a probabilistic assessment of the classification, we identified seven significantchorotypes: four multispecific and three monospecific. The compound chorotypesgrouped together species that tended to share certain characteristics about theirintroduction, release cause, establishment, and spread. We modelled the chorotypesusing a favourability function based on a generalized linear model and 31 variablesrelated to spatial situation, topography, lithology, climatic stability, energy availability,water availability, disturbances, productivity, and human activity. Climatic factorsaffected the favourability for every chorotype, whereas human variables had a highinfluence in the distribution of three chorotypes involving eight species. On the basisof these variables, we identified favourable areas for all the chorotypes in mainlandSpain. The favourability for a chorotype in an area may be a useful criterion forevaluating the local conservation concern due to the whole set of species. Favourable but unoccupied areas can be used to infer possible colonization areas for eachchorotype. We recommend using chorotypes to optimize broad-scale surveillance ofinvasive species.
