The Gulf Coast is home to many amphibian species, and in fact, the region is near the top for amphibian species richness in the United States. Amphibians are a key vital sign for monitoring in Gulf Coast Network parks because
- Many amphibian species are geographically restricted, which means they are only found in a few locations.
- Some parks have specifically identified at-risk species in their management plan.
- Amphibians are good indicators of wider ecosystem change because they have semi-permeable skin and often have aquatic larval stages. This makes them highly sensitve to habitat change and particularly to changes in water quality.
The complete background, rationale and procedures for amphibian monitoring by the network are described in a protocol narrative and 8 standard operating procedure (SOP) documents. The protocol is titled "Monitoring Amphibians in Gulf Coast Network Parks". It will be published in the NPS Natural Resource Report Series in late 2018, after which it will be made publicly available on IRMA.
