Endemic Plant Species

Invasive plant species are increasingly altering species composition and the functioning of ecosystems from a local to a global scale. The grass species Pennisetum setaceum has recently raised concerns as an invader on different archipelagos worldwide. Among these affected archipelagos are the Canary Islands, which are a hotspot of endemism. Consequently, conservation managers and stakeholders are interested in the potential spreading of this species in the archipelago. We identify the current extent of the suitable habitat for P. setaceum on the island of La Palma to assess how it affects island ecosystems, protected areas (PAs), and endemic plant species richness. We recorded in situ occurrences of P. setaceum from 2010 to 2018 and compiled additional ones from databases at a 500 m × 500 m resolution. To assess the current suitable habitat and possible distribution patterns of P. setaceum on the island, we built an ensemble model. We projected habitat suitability for island ecosystems and PAs and identified risks for total as well as endemic plant species richness. The suitable habitat for P. setaceum is calculated to cover 34.7% of the surface of La Palma. In open ecosystems at low to mid elevations, where native ecosystems are already under pressure by land use and human activities, the spread of the invader will likely lead to additional threats to endemic plant species. Forest ecosystems (e.g., broadleaved evergreen and coniferous forests) are not likely to be affected by the spread of P. setaceum because of its heliophilous nature. Our projection of suitable habitat of P. setaceum within ecosystems and PAs on La Palma supports conservationists and policymakers in prioritizing management and control measures and acts as an example for the potential threat of this graminoid invader on other islands.

AbstractInvasive species are one of the main threats to the loss of global biodiversity. Controlling such species requires a high input of effort and resources and therefore it is important to focus control on areas that will maximize gains for conservation. We present a spatial modelling approach that will help target control efforts. We used presence-only data to develop habitat suitability models for the invasive tree Casuarina equisetifolia and three endemic plant species on the Turks and Caicos Islands in the Caribbean. Substantial overlap was found between suitable areas for the endemics and C. equisetifolia. Evidence for the potential harm that C. equisetifolia could cause to native vegetation was assessed using paired areas with and without invasion. Areas with C. equisetifolia present had lower native plant species richness than areas where it was absent, which suggests a negative effect of invasion on the growth of native plants. No endemic plants were found in areas where C. equisetifolia was present. Based on the data collected we recommend that the three endemic species be categorized as Endangered on the IUCN Red List. By highlighting areas where the endemic plants are found and demonstrating a potential threat to these habitats, we provide a plan for the designation of six Important Plant Areas to promote conservation of these endemic species.
