Pacific Island Network Streams Monitoring Dataset 2009 - 2023

Throughout the world, freshwater ecosystems are considered to be among the most vulnerable systems. In the isolated Pacific islands, there are a relatively small number of native freshwater species, which are mainly endemic to these locations. Throughout the region, native flora and fauna face significant threats from species introductions and habitat destruction. The National Parks in the Pacific Island Network (PACN) protect some of the last relatively pristine stream systems. The Pacific Islands Stream Monitoring Protocol monitors long term changes in stream communities for four of the Pacific Island parks. This dataset contains results from 2009 through 2023 stream animal surveys in HALE, KALA, NPSA, and WAPA and will provide park managers with information necessary to understand status and trends in biotic integrity within park stream systems. This project is ongoing and will be updated annually.
