Supporting documents and datasets associated with implementing the NETN's Permanent Freshwater Monitoring Protocol. The overall goal is to monitor status and trends in the structure, function and condition of ACAD's permanent wetland ecosystems in order to inform management decisions affecting those systems. First year of data collection was 2012. Annual protocols were produced starting in 2012 but were first published as part of a NPS reporting series starting in 2013. Our overall goal is to monitor status and trends in the structure, function, and condition of Acadia National Park's permanent wetland ecosystems in order to inform management decisions affecting those systems. The sampling design is comprised of a combination of intensive monitoring in ten sentinel sites, and rapid assessments in a larger number of randomly selected sites. Generalized random tessellation stratified sampling (GRTS) will be used to locate sites for rapid assessment (Level 1 and 2) sampling. After two sampling cycles are complete, a power analyses will be conducted on key variables to determine the level of change that can be detected with the current sample size, and to determine realistic and appropriate levels of Type I and Type II error. At a minimum, we want to detect a 50% decline or increase in any metric after two survey cycles, while controlling both Type I and Type II error at 20%. More information regarding the purpose and methods of this monitoring effort can be obtained from the protocol.
