Ecoregional Conservation Assessment for the Coastal Forests and Mountains for British Columbia and Southeast Alaska
This dataset represents an assessment of the ecological integrity of all watersheds in the study area based on relative levels of human impacts.
This
work represents a joint effort between Round River Conservation Studies (RRCS),
The Nature Conservancy of Canada (NCC), The Nature Conservancy – Alaska (TNC), with
assistance from the Coastal Information Team (CIT) Ecosystem Spatial Analysis
Planning Team. This effort included a diverse group of researchers from
non-governmental and government agencies and represents a collective of
researchers and practitioners in the fields of conservation biology, ecology,
zoology, Geographical Information Systems (GIS), and land-use planning.
We sought to develop science-based tools and to assemble regional
data necessary to address these sorts of questions, through the development of
a Conservation Area Design (CAD) for the region. Here we present regional
spatial datasets that represent a full range of biodiversity values for the
coastal temperate rainforest. We also present analyses results that identify
high value, irreplaceable conservation areas and identify some of the last
remaining, ecologically intact and relatively undisturbed watersheds in the
region.
This
report provides tools and data necessary for science based conservation
planning and a framework of how priority areas can be systematically
identified. The objective of this exercise is ultimately to serve four
well-accepted goals of conservation: 1) represent ecosystems across their
natural range of variation; 2) maintain viable populations of native species;
3) sustain ecological and evolutionary processes within an acceptable range of
variability; and 4) build a conservation network that is resilient to
environmental change. In pursuit of these goals, the Conservation Area Design
for the CFM region incorporates three basic approaches to conservation planning:
·
Representation of a broad spectrum of
environmental variation (e.g., vegetation, terrestrial abiotic, and freshwater and
marine habitat classes).
·
Protection of special elements:
concentrations of ecological communities; rare or at-risk ecological
communities; rare physical habitats; concentrations of species; locations of at
risk species; locations of highly valued species or their critical habitats;
locations of major genetic variants.
·
Conservation of critical habitats of
focal species, whose needs help planners address issues of habitat area, configuration,
and quality. These are species that (a) need large areas or several well
connected areas, or (b) are sensitive to human disturbance, and (c) for which
sound habitat-suability models are available or can be constructed.
