Wisconsin's State Natural Areas Program was created in 1951 and was the first state-sponsored programo of its kind in the United States. It was developed with guidance from early conservationists such as Aldo Leopold, Norman C. Fassett, Albert Fuller, and John Thomas Curtis.

In ecology, crypsis is the ability of an animal or a plant [1] to avoid observation or detection by other animals. It may be part of a predation strategy or an antipredator adaptation . Methods include camouflage , nocturnality , subterranean lifestyle and mimicry .
Professor Lawrence Martin created a schema for dividing Wisconsin into geographical regions in his work "The Physical Geography of Wisconsin". [1] [2] Western Upland; Eastern Ridges and Lowlands; Central Plain; Northern Highland; Lake Superior Lowland; Three of these geographical provinces are uplands and two are lowlands.
The Crex Meadows Wildlife Area consists of marshes, wetlands, brush prairies, and forests. Crex Meadows is located near the village of Grantsburg, Wisconsin , in Burnett County . Its 30,000 acres (120 km 2 ) are home to 270 species of birds and 600 species of plants.
Experiments on blue jays suggest they form a search image for certain prey.. Visual predators may form what is termed a search image of certain prey.. Predators need not locate their host directly: Kestrels, for instance, are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example.
The coloration of the Papuan frogmouth Podargus papuensis, its outline disrupted by its plumage, its eye concealed in a stripe, is an effective anti-predator adaptation. Disruptive coloration (also known as disruptive camouflage or disruptive patterning ) is a form of camouflage that works by breaking up the outlines of an animal, soldier or ...
Studies evaluating the role of crypsis on herbivory measure leaf quality, such as nitrogen and protein levels, water content, etc. [4] Ehleringer et al. examined nitrogen levels, as an indicator of protein status, of mistletoe and their host (Acacia, Cassia, Casuarina, Ceriops, and Eucalyptus) to determine if mimicry reduced herbivory in the plant.
Black Earth Rettenmund Prairie is a Wisconsin Department of Natural Resources-designated State Natural Area featuring one of the few remaining dry-mesic prairies in Wisconsin, situated on a low Driftless Area knob and ridge. Despite the prairie's relatively small size, 130 native prairie plant species have been documented on the site.
