Long-term Natural Resource Monitoring
Temperate Times Newsletter
From the Report:
"Invasive species" are alien species that cause or are likely to cause harm to the economy, environment, and/or human health, and are considered to be one of the leading threats to the biodiversity and integrity of ecosystems worldwide. In broad terms, they are organisms that have been introduced deliberately or unintentionally into an environment where they did not evolve, are capable of establishing self-sustaining populations in "untransformed ecosystems", and have no natural enemies to limit their reproduction and spread. These are among the reasons why early detection of invasive species was identified as a priority vital sign by several Inventory and Monitoring networks including the Northeast Temperate Network (NETN).

Forests of the northeastern U.S. have a long history of change, resiliency, and recovery. Long-term health of the forests of NETN parks is a high-priority for the network. The goals of the forest monitoring program are to assess status and trends in the composition, structure, and function of forested ecosystems, and to interpret and report the condition of forest systems in a way that effectively informs park managers and the public.

Frederick Law Olmsted Sr. wrote to George Perkins Marsh in 1857, asking his advice on promoting "free soil" settlement in Texas to challenge the westward expansion of slavery. Strongly anti-slavery, both men would also champion land stewardship and public access to places like Yosemite Valley.
