Background and aims: Invasive species are the greatest threat to conservation. The objectives of this study were to identify the flora that thrive in a hill grassland of the Paititi Natural Reserve, to perform an early detection of non-native plant species that might be acting as invasive, and to establish the current situation of the native species considered threatened.
M&M: Following the altitudinal gradient, 14 sites were selected; the environmental characteristics and cover-abundance of the vascular plant species were recorded in each site. With the collected data, a Principal Coordinate Analysis (PCooA) was performed to group the sites into vegetation units that were later described considering environmental characteristics, identified species and plant community type. Additionally, the threatened species were specified, as well as the most abundant exotic ones, therefore considered invasive.
Results: Total richness reached 370 species, 26.5% corresponding to non-native ones. Thirty threatened species were identified. The PCooA grouped the sites into eight vegetation units. The non-native species considered invasive were Dactylis glomerata, Senecio madagascariensis, Holcus lanatus and Racosperma melanoxylon, these last two reached the highest coverage-abundance values.
Conclusions: To conserve biodiversity and minimize the invasion process, management efforts should be focused on monitoring the threatened species and controlling the advance of the non-native species acting as invasive. Early detection of those species in similar environments would be fundamental to facilitate rapid responses towards reducing invasions. |

Introducción y objetivos: Las especies invasoras representan la mayor amenaza para la conservación. Los objetivos de este estudio fueron identificar la flora del pastizal serrano de la Reserva Natural Paititi, realizar la detección temprana de especies vegetales exóticas que pudieran estar actuando como invasoras y establecer la situación actual de aquellas especies nativas consideradas amenazadas.M&M: Siguiendo el gradiente altitudinal se seleccionaron 14 sitios donde se registraron las características ambientales y la cobertura-abundancia de las especies vasculares. Con los datos recabados se realizó un Análisis de Coordenadas Principales (ACooP) que originó unidades de vegetación que fueron descritas según características ambientales, especies identificadas y tipo de comunidad vegetal. Adicionalmente, se destacaron las especies amenazadas y las exóticas más abundantes, en consecuencia consideradas invasoras.Resultados: La riqueza total fue de 370 especies, correspondiendo el 26,5% a exóticas. Se identificaron 30 especies amenazadas. El ACooP reconoció ocho unidades de vegetación. Las especies consideradas invasoras fueron Dactylis glomerata, Senecio madagascariensis, Holcus lanatus y Racosperma melanoxylon, estas dos últimas con los mayores valores de cobertura.Conclusiones: Para conservar la biodiversidad y minimizar el proceso de invasión, los esfuerzos de manejo deberían enfocarse en monitorear las especies amenazadas y controlar el avance de las invasoras. La detección temprana de dichas especies en ambientes similares sería fundamental para reducir invasiones vegetales.
