Nearly 600 terrestrial ecological systems in the United States, southern Alaska, and adjacent areas of Mexico and Canada are summarized in this report, which introduces and outlines the conceptual basis for a mid-scale classification unit: the ecological system.
A comprehensive assessment of aquatic biodiversity across the entire Upper Mississippi, including a complete classification of aquatic systems and identification of 22 areas of freshwater biodiversity significance.
This working ecological classification summarizes nearly 700 terrestrial ecological systems of Latin America and the Caribbean, and describes applications of these systems for conservation assessment, ecological inventory and monitoring, land management, and other uses.
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.
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
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
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.
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.
