Patrones de urbanización en la biodiversidad de humedales urbanos en Concepción metropolitano

Abstract: RESUMENLa urbanización en Concepción metropolitano (36°S) en las últimas décadas ha impactado áreas de valor ecológico, tales como humedales y lagunas. Aquí analizamos la perturbación de parámetros de biodiversidad en seis humedales urbanos, mediante la exploración y uso de indicadores. Se proponen tres indicadores: naturalidad y riqueza de macrolepidópteros y plantas, los que se evalúan mediante modelos de regresión múltiple. Los resultados indican que los humedales con menor grado de perturbación antrópica s… Show more

“…According to Zorrilla-Miras et al [12], engines of change are generally interrelated. Indeed, in the Mediterranean region of Chile-specifically in the closer coastal area-increases in production and industrial activities, population, and the level of urbanization have been associated with the loss of surface and biodiversity of these kinds of ecosystems [57][58][59]. The spread of exotic species such as Pinus radiata is a threat to wetlands as it affects native flora and fauna and causes an alteration in ecosystem functions.…”

“…In addition, there is also a lack of articulation between the institutions with jurisdiction for wetland protection, monitoring and sanctioning at local, regional and national levels (Rojas et al 2015), creating an opportunity for uncontrolled use. In Chile, a wetland can be in several, one or none of five protection categories.…”

“…Urban wetlands are a particular type of urban green area under significant stress, due to urban expansion (Millennium Ecosystem Assessment 2005) and deficient articulation of planning instruments (Rojas et al 2015). For example, in the Chilean case, urban wetlands are not deemed to be significantly important under State regulations, and therefore are not protected by law.…”

“…Aquí, el entorno natural y paisajístico de Boca Sur se encuentra altamente degradado (Smith y Romero, 2009;Vásquez y Salgado, 2011;Rojas et al, 2015), existe urgencia en recuperarlos por su función estabilizadora del litoral y otras tales como: servir de mecanismo de disipación natural frente a amenazas naturales, tales como tsunamis, marejadas y crecidas de ríos; servir de patrimonio natural para desarrollar economías locales; servir de reservorios, aportar servicios ecosistémicos a la comuna y servir de lugares de restauración en situaciones de postdesastre. Desde el punto de vista del manejo de emergencias y recuperación postdesastre, estos sectores suelen convertirse en lugares restauradores desde un punto de vista físico y cultural, ya que los mismos habitantes utilizan para proveer de servicios básicos (agua) e inclusive restauración emocional, tal como fue probado con el terremoto de 1960 en Valdivia y 2010 en San Pedro (Villagra y Rojas, 2013;Villagra & Dobbie, 2014;Villagra & Felsenhardt, 2015).…”
