Daños producidos por Ganado asilvestrado en las comunidades vegetales del Parque Rural de Anaga (Tenerife).

Endemic flora species are more palatable to invasive herbivores than non-endemic species. In this work we quantified the percentage of damage caused by feral goat on the flora of the Anaga Rural Park. We assessed whether cattle are causing changes in vegetation composition in Morello-Ericetum arboreae and nitrophilous shrub ArtemisioRumicetum lunariae. For this purpose, 16 transects were carried out, in which the cover and level of goat damage of each species were estimated and data on different abiotic variables were collected. The percentage of damaged endemics was positively correlated with the goat droppings index. With respect to the type of community, the results obtained showed a greater damage to endemic species compared to non-endemic species in both open scrubland and forest formations, endangering the survival of many threatened endemic species present exclusively in this natural area.
