Abstract
La vegetación de los humedales desempeña un papel crucial en es estos ecosistemas, fundamentales por su biodiversidad, por ofrecer numerosos servicios ecosistémicos y por mitigar el cambio climático. A pesar de esto, se conoce muy poco sobre la riqueza y la diversidad de las especies presentes en los humedales urbanos. El objetivo de este trabajo fue estudiar la vegetación de la ribera de humedales delimitadas por las zonas de protección establecidas por el Decreto 82 de la ley 21.283, esto en cuatro humedales urbanos con distinto grado de urbanización obtenidos a través de la distancia promedio de los tres asentamientos urbanos más próximos, en la comuna de Coronel, Región del Biobío. Se encontró una riqueza total de 91 especies, de las cuales 59,34% fueron de origen exótico. Además, los resultados muestran una relación entre la distancia de los centros urbanos y la riqueza de especies exóticas, donde aquellos humedales con mayor grado de urbanización poseen una mayor presencia de especies exóticas. Se señala la presencia de una especie con categoría de conservación vulnerable para el humedal más alejado de los centros urbanos, siendo este el único humedal estudiado con especies nativas y endémicas no encontradas en los otros humedales.
Wetland vegetation plays a crucial role in these ecosystems, which are fundamental for their biodiversity, for providing numerous ecosystem services and for mitigating climate change. Despite this, very little is known about the richness and diversity of species present in urban wetlands. The objective of this work was to study the vegetation of the banks of wetlands delimited by the protection zones established by Decree 82 of Law 21.283, in four urban wetlands with different degrees of urbanization obtained through the average distance of the three nearest urban settlements, in the commune of Coronel, Biobío Region. A total richness of 91 species was found, of which 59.34% were of exotic origin. In addition, the results show a relationship between distance from urban centers and the richness of exotic species, where those wetlands with a higher degree of urbanization have a greater presence of exotic species. The presence of a species with a vulnerable conservation category is noted for the wetland farthest from the urban centers, this being the only wetland studied with native and endemic species not found in the other wetlands.
