“…More than 75% of our sites are over this level, which could suggest a possible threat to the species under this context. Although these species declines may have multiple causes (Alford et al, 2001;Collins & Storfer, 2003), the degradation of ecosystems, poor water quality in rivers, and deforestation may likely be one of the main threats facing biodiversity in El Salvador (Dull, 2008;Crespin & Simonetti, 2015;MARN, 2022), even, exist risk by introduction of the amphibian alien species (see Antúnez-Fonseca et al, 2021). Currently, only ~8% of the Salvadorean territory corresponds to protected areas (UNEP-WCMC, 2019), and very few of these areas have connectivity in the country, a widespread apparently problem throughout the world (Ward et al, 2020).…”
