Guide to Significant Wildlife Habitat - Door County Web Map

On the Pacific coast of North America, old-growth characteristics begin to appear in unmanaged
forests of 175 to 250 years of age, but this will vary considerably across the continent, depending on the
site and forest type. See also second-growth forest. (from Dictionary of Natural Resource Management,
Julian & Katherine Dunster 1996, UBC Press, Vancouver, BC)
open space
Land that is largely free of man-made structures, where ground cover is such that rain may enter
the soil to replenish groundwater. May include but is not limited to natural areas, parks, and agricultural
lands. (adapted from Land Protection Options, L. Allmann)
population
In biology, any group of organisms belonging to the same species at the same time and place.
(from Saving Nature's Legacy, R. Noss and A. Cooperrider)
riparian
Relating to or living or located on the bank of a natural watercourse (as a river or stream) or
sometimes of a lake. (adapted from Webster's New Collegiate Dictionary)
second-growth forest
Relatively young forests that have developed following a disturbance (e.g., wholesale cutting,
extensive fire, insect attack) of the previous stand of old-growth forest. Restricted in application to those
parts of the world where clearly discernible, old-growth forest still exist, or did exist not long ago. See
also old growth forest. (from Dictionary of Natural Resource Management, Julian & Katherine Dunster,
1996, UBC Press, Vancouver, BC)
State natural area
Sites formally designated by the WDNR that contain outstanding examples of native biotic
communities and are often the last refuges in the state for rare and endangered species of plants and
animals. Areas are devoted to scientific research, the teaching of conservation biology, and especially to
the preservation of their natural values and genetic diversity for future generations. (See also, Appendix D
for additional information)
understory
The trees and other woody species growing under the canopies of large adjacent trees and other
woody growth. See canopy. (from Dictionary of Natural Resource Management, Julian & Katherine
Dunster, 1996, UBC Press, Vancouver, BC)
warm water forage fishery
Stream or lake waters which support fishes with a maximum summer water temperature tolerance
of about 80 degrees Fahrenheit. Bluegills, perch, and largemouth bass are examples. (U.S. Forest Service,
FSM 2605, Sept 1974)
watershed
An area of land, which may or may not be under forest cover, draining water, organic matter,
dissolved nutrients, and sediments into a lake or stream. (from Dictionary of Natural Resource
Management, Julian & Katherine Dunster, 1996, UBC Press, Vancouver, BC)
wildlife corridor
1) an area of continuous native vegetation designed to promote connectivity and movement of
wildlife between isolated natural areas, or 2) a series of patches of natural vegetation that may serve as
"stepping stones" that promote connectivity and movement of wildlife between natural areas. (adapted
from Ecology of Greenways, Smith et. al.) The natural, sequential change of species composition of a
community in a given area. (from Principles of Conservation Biology, G. Meffe and C. Carrol et. al.)
xeric
Refers to a habitat characterized by dry conditions rather than mesic (moderate) or hygric (wet)
conditions. (from Dictionary of Ecology, Hanson, Herbert C. 1962Philosophical Library, N.Y., 382 p.)
