Recent surveys and historical data describe vegetation patterns in the coastal salt pond marsh system at Odiorne Point State Park in Rye, New Hampshire, the state's only viable example.
Main elements of this project include: the suitability of existing spatial datasets and classification systems as the basis for sampling design, metrics for various aspects of wetland condition, and synthesizing the results into an ecological integrity scoring system.
NatureServe's project “Assessment of Wetland Ecosystem Conditions across Landscape Regions – a Multi-metric Approach” was conducted with the natural heritage programs of Indiana and Michigan, and included assessment of roughly 360 wetland sites in those two states.
By highlighting 12 invasive species that have been especially destructive, this seminal report encapsulates the threat to biodiversity posed by alien species and describes conservation solutions to help stem the mounting crisis
Documents the U.S. as a leader in the diversity of freshwater species, summarizes the conservation status of freshwater species by group, identifies freshwater biodiversity hotspots, and describes conservation solutions
International organizations seriously concerned with the preservation of biodiversity find themselves confronted with the enormous task of establishing a hierarchy of sites in need of attention.
With environmental change wreaking widespread shifts in species distribution, some plant communities will likely disappear while entirely new ones will appear within our lifetime. This reality requires an understanding of the distribution of plants species and careful definition within a consistent typological framework.
This report classifies and maps the natural vegetation of Voyageurs National Park --which contains 54,243 hectares of terrestrial, sub-boreal habitat -- using the USNVC, with ‘alliance’ and ‘association’ as base units.
