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.
The invasion of true clover into New Zealand is the focus of this analysis of the human role in the introduction and proliferation of nonnative species.
This report represents Québec’s first effort to identify bryophyte species in need of protection, the hope being to attract stakeholder interest in the long-neglected organism.
This illuminating and instructive book explores New Hampshire's stunning mosaic of natural communities, taking the reader on a tour of landscapes as varied as alpine meadows, tidal marshes, riverbanks, forests, ponds, dunes, and cliffs.

This 271-page book covers terrestrial, freshwater palustrine, riparian, and estuarine communities in New Hampshire, and includes a concise overview of the Granite State's landforms, climate, regional vegetation patterns, and ecoregions.
The lack of conservation remedies for the poorly understood decline of amphibian populations worldwide has left hundreds of these species to face extinction.
Forty-two out of 113 species of Harlequin frogs have seen their population cut by at least half, while 30 species are feared extinct. The likely culprits: climate change and the Batrachochytrium fungus.
