Strong negative effect of alien herbivores on endemic legumes of the Canary pine forest

We studied the effects of herbivores on populations of four endemic legume species in pine forests in Caldera de Taburiente National Park on La Palma, Canary Islands. Seeds of these species were sown in control and herbivore-exclusion plots. Over the subsequent 4-years period, we assessed the effects of herbivores by counting the number of individual plants that emerged and by following their growth. We assessed growth over time using three...
