| description | Anthropogenic activities threaten more and more the extension and processes of ecosystems. The IUCN Red List of Ecosystems (RLE) is a global standard for assessing their risk of collapse. In this paper, global trends of risk assessments of terrestrial and wetland ecosystems were analyzed through a search for and analysis of publications from 2010 to 2019 that utilized the RLE protocols. Forty-three publications that evaluated 1227 ecosystems: forests (531), scrublands (181), grasslands and herbaceous (212), wetlands (166), coastal (42), and sparsely vegetated or uncommon ecosystems (95) were found. Fifteen criteria were recorded to delimit the ecosystems, highlighting the type of vegetation used as a proxy in all cases. There was a strong variation in the extension of the ecosystems evaluated. Thirty-four variables were identified to define collapse thresholds: one spatial, 15 biotics, and 18 abiotics; vegetation cover change, geographic distribution, and extension were variables of general application. The periods of reliable data for assessing ecosystems range from 12 to 48 years; with them, 50-year periods (past or future) or changes deductied since 1750 were inferred. Ecosystems in "Least Concern" (412) stood out, only two "collapsed" were found, and there was no significant difference between threatened and non-threatened. The assessments analyzed comprised 69 countries, which were conducted at continental, national, and subnational scales. Improvements in the RLE protocols are proposed and key information is provided for the application of ecosystems risk assessment in the future. |

Las actividades antropogénicas amenazan cada vez más la extensión y procesos de los ecosistemas. La Lista Roja de Ecosistemas (LRE) de la Unión Internacional para la Conservación de la Naturaleza (IUCN, por sus siglas en inglés) es un estándar global para evaluar su riesgo de colapso. En este trabajo se analizaron las tendencias mundiales en las evaluaciones de riesgo de los ecosistemas terrestres y humedales, mediante la búsqueda y análisis de publicaciones del 2010 a 2019 que aplicaron los protocolos de la LRE. Se encontraron 43 publicaciones que evaluaron 1227 ecosistemas: bosques (531), matorrales (181), pastizales y herbazales (212), humedales (166), costeros (42) y de vegetación escasa o poco comunes (95). Se registraron 15 criterios para delimitar los ecosistemas, destacó el tipo de vegetación usada como proxy en todos los casos. Existió una fuerte variación en las extensiones de los ecosistemas. Se identificaron 34 variables para definir umbrales de colapso: una espacial, 15 bióticas y 18 abióticas; el cambio en la cobertura vegetal, extensión y distribución geográfica fueron de aplicación general. Los periodos de datos fiables para evaluar ecosistemas van de 12 a 48 años, con ellos se infirieron lapsos de 50 años (pasado o futuro), o se dedujeron cambios desde 1750. Sobresalieron los ecosistemas en “Preocupación Menor” (412), se encontraron solo dos “colapsados” y no hubo diferencia significativa entre amenazados y no-amenazados. Las evaluaciones analizadas incidieron en 69 países, se realizaron a escalas continentales, nacionales y subnacionales. Se proponen mejoras a los protocolos de la LRE y se proporciona información clave para aplicar en evaluaciones de riesgo ecosistémico en el futuro.
