Resumen:

The success of biological invasions depends on two important components: The set of species traits that improves their ability to become invasive (invasiveness) and characteristics of the receiving ecosystem (invasive potential). Descriptions of these two components have yielded information that can lead to evaluate the risk posed by a specific species in a given ecosystem. Current information on IAS gives a highly biased distribution but clearly biased by a lack of systematic sampling, ongoing disturbance, and environmental conditions. Sampling of the Sierra Gorda Biosphere Reserve exemplifies the underestimation of IAS as well as the extent within the area. We used an estimate of invasion potential using phylogenetic diversity, human disturbance, and invasiveness on a 15-×-20' grid depicting the risk posed by IAS. There is a clearly an urgent need to have nationwide surveys and adoption of risk assessments so as to standardize a national effort to overcome the problems associated with IAS. © 2021 John Wiley and Sons Ltd.
