It's not possible to measure and collect data on everything from our vast and complex planet. Scientists, however, have found a way to still study and learn about how earth’s different ecosystems work. They do this using "vital signs."
Vital signs are indicators of an ecosystem’s overall health, and can be a specific animal, habitat, or abiotic factor (such as water, air, or soil). By monitoring vital signs over a long period of time, scientists better understand how each one impacts and responds to changes in the greater ecosystem. Having this understanding can help parks preserve unimpaired the natural resources for future generations.
The Northeast Coastal and Barrier Network monitors a diverse range of vital signs in our eight parks. We collect data from salt marshes, coastal shores, upland forests, and estuaries. And we monitor vital signs from salt marsh plants and fish to estuarine water quality and ocean shoreline change. With our data, we gain a clearer picture of biodiversity and environment at each park and throughout the region. Doing so helps provide a scientific foundation for park management and the education of our visitors.
Invasive exotic plants, white-tailed deer, diseases and pathogens, and native forest pests have greatly impacted the forests of New England.
Habitats at the intersection of river and sea, estuaries are a unique blend of freshwater that drains from land and saltwater from the sea.
