Habitat loss and degradation are well recognized as the largest threat to amphibian populations around the world. Our limited understanding of species ecology, biology and taxonomy is further limiting our ability to define what constitutes a critical habitat for amphibians that may need protection. This often leads to amphibian data and habitat needs not being incorporated into both local and national conservation policies. Further complicating matters are local communities that often do not fully understand the important roles amphibians play within the ecosystem or the importance of protecting their habitats.
The threats that amphibians could face from climate change are not very well understood, or which species for that matter are mostly likely to be affected by climate change. It’s even possible that many habitats rich with amphibians are already being impacted by climate change, which in turn could result in the potential extinction of entire species. Thus, there is an urgent need to fully understand the impacts of climate change, which may already be affecting amphibians quicker than we are able to find solutions for.
Unfortunately, many priority amphibian species or biodiverse priority regions have no conservation strategies in place for them. Even basic information on species distributions, ranges, population sizes, conservation status and threats for many species and regions is still lacking around the world. Surveys and monitoring efforts would help address the issue of these missing details, but survey efforts are not standardized which makes comparisons and achievement of conservation goals quite difficult. Traditional survey and collection approaches to monitor certain threatened, rare and/or cryptic species are often not suitable, whereas novel monitoring techniques currently being explored, such as environmental DNA and automated recording devices may be preferred. A lack of collaboration and coordination in survey and monitoring efforts, misidentifications in the field which lead to inaccurate conclusions as well as a lack of information and buy-in on survey and monitoring initiatives are all impacting amphibian and habitat conservation efforts.
The Alliance is now prioritizing efforts on developing a transparent framework through which conservation practitioners and funders can more effectively partner to save critical sites for amphibians. This framework will be key to scaling up our impact through the Leapfrog Conservation Fund and our other strategies to help protect these vital sites for amphibians and the broader biodiversity value that they support.
We are also working with our Partners around the world to develop a better understanding of the potential impacts that climate change has on amphibians. These efforts are focused on improving our understanding of the species to be most affected by any changes in climatic conditions and how those particular species will likely be impacted. Through this process we aim to help direct the conservation prioritization and planning processes for range restricted and threatened species.
Furthermore, Alliance Partners are now identifying and working with disease experts to prioritize the development of standardized screening methods for amphibian diseases. At the same time, because of the limitations posed by traditional survey and collection approaches when monitoring threatened, rare and/ or cryptic species, we are also investigating the advantages of more novel monitoring techniques such as environmental DNA (eDNA) and automated recording devices as well as standardizing survey/monitoring techniques. Our Partners can then use these standardized protocols when harnessing the power of citizen science.
The overall effectiveness of existing conservation strategies for amphibians is also being reassessed by our Partners and the Alliance will work with Partners to develop any necessary conservation strategies.
The Amphibian Survival Alliance is an alliance of action and turn the ACAP priorities into real action for amphibians. Here are some of our latest projects:

- Recruit two new partners support large habitat conservation initiatives.
- Identify a set of characteristics which make amphibians vulnerable to climate change.
- Identify a set of high priority species.
- Model climate change impacts on 20% of priority species under existing scenarios and models.
- Literature survey and consultation with experts on the use of eDNA to create a working document subject to annual revision.
- Literature review and survey of individuals working in the field of passive acoustic monitoring to create one working document subject to continual revision.
- Matching six experts with students or others interested in PAM.
- Develop guidelines for choosing state variables in monitoring programs and surveys (e.g., should we measure species richness, occupancy, abundance, occurrence of reproduction (tadpoles), life history traits, etc.).
- Develop guidelines for ancillary data (predators, competitors, pathogens, environmental features, possible contaminants, etc.) to be collected in surveys.
- Develop a simplified protocol for adoption and application by citizen science.
- Identify and contact three citizen sciences initiatives that would be interested in partnering for amphibian surveys and monitoring.
- Survey six museums and researchers to determine their field collections guidelines and integrate into best-practice document.
- Develop a better understanding of which GIS data are available and relevant for amphibians (depends on spatial scale), inclusive of literature review and experimentation with GIS (more experimental use of GIS, e.g., making and testing predictions, revising when they prove inaccurate, repeat).
- Develop guidelines for how to analyze and interpret spatial data collected in surveys.
- Recruit six volunteers to collate existing keys by regions; develop lists of keys for taxa/areas to identify existing resources; reach out to six taxonomic experts to assess quality and usefulness of keys.
- Knowledge gaps on the impact and significance of amphibians in community and ecosystem dynamics – review of relevant literature for amphibians in terrestrial and aquatic systems.
- Recruit volunteers to review existing literature on amphibians and ecosystem services.
- Support the integration of Bd/Bsal and ranavirus surveys into all biodiversity survey work.
- Collaborate with disease experts to incorporate disease and pathogen detection into monitoring programs.
- Develop resources (funds, citizen science initiatives) that would allow for ground truthing and border expansion of presently understood species ranges. This can be prioritized by the conservation status of species, e.g., Least Concern species are low priority unless they are disease carriers.
- Act as a clearinghouse where students looking for graduate projects at universities are matched to priority actions.

Surveys are extremely useful as they provide conservationists and researchers a quick snap-shot of the status and distribution of amphibian communities, species and populations, along with the quality of their habitat and/or habitat requirements. Multiple surveys of the same areas over time (i.e. monitoring) provides additional information about potential trends or patterns observed. Given that amphibians are generally in meta-populations, the impacts of climate change and habitat loss are often difficult to discern as local population extinctions and declines can be both natural and anthropogenically-induced events. Long-term monitoring helps elucidate these impacts.
Only through surveys and monitoring can we identify the impacts certain threats have on amphibians. Without this knowledge, conservationists will be unable to respond effectively to prevent further amphibian declines.
- the ecology of all life stages in an amphibians’ life cycle, particularly for habitat requirements
- whether or not the survey was carried out in breeding or non-breeding sites/in breeding or non-breeding seasons
- the dispersal ability of the species
- the detectability of the species
- the surveyors’ effort
- the influence of time (for data derived from monitoring)
- possible sex effects in habitat use or distribution (i.e. do males congregate in certain areas to attract females?)
- competition from conspecifics (i.e. individuals from the same species) and/or interspecific individuals (i.e. individuals from other species)
These are the key findings that will inform conservationists and researchers on how, when, and where to manage amphibian species.
