Resumen
Habitat loss is the primary driver of amphibian declines. The protection and management of habitats are thus
the most critical conservation actions needed for at least 60% of amphibians, with habitat loss accounting for
population declines and extinctions at local and regional levels. Habitat loss is directly related to pollution, but it also
exacerbates other major threats to amphibians, such as disease, illegal trade, and invasive species. Habitat loss
also reduces the ability of amphibian species to disperse and alter their distribution within their ecophysiological
tolerance ranges in order to adapt to climate change. Currently, less than 30% of amphibian species are
represented in the global protected-area system. The restricted geographic distribution, high habitat-specificity,
and dependence on narrow climatic envelopes of many amphibian species mean that amphibians are particularly
prone to local extinctions. Of the 37 amphibian species reported as extinct as of 2021, 48.6% were distributed in
South and Southeast Asia, and 21% in Mesoamerica. These species mainly inhabited inland wetlands and forests.
Considerable research into understanding the effects of habitat loss, fragmentation and degradation on amphibians
have been undertaken over the past 15 years, including a review on the effectiveness of amphibian-targeted
conservation interventions.
Habitat protection and management priorities must include the urgent preservation of remnant native forest habitats,
given that over 85% of amphibian species occur in these systems. Conservation actions must also include the
protection and rehabilitation of other aquatic and terrestrial breeding habitats critical for supporting viable amphibian
populations. Given the limited resources for conservation, protection of globally important sites for amphibians
(such as Alliance for Zero Extinction- AZE, and Key Biodiversity Areas - KBA), and their integration with protected
areas into a network of conservation areas, is a key priority. The creation, rehabilitation and restoration of amphibian
habitats, including in urban and agricultural landscapes, must not be excluded from the toolkit of interventions needed to avoid declines of more generalist species. Beyond implementing direct habitat protection mechanisms, it
is essential to ensure targeted management of newly created protected areas and improve that of existing protected
areas, inclusive of amphibians. For these actions to be sustainable, it is critical to facilitate the participation,
communication, and involvement of a broad range of stakeholders, including government entities, productiveextractive
sectors, NGOs, academia, local communities, and civil society.
