Polanisia jamesii, common name James's clammyweed, is a plant species native to the central part of the United States. It is reported from Minnesota, Wisconsin, Ohio, Indiana, Illinois, Iowa, South Dakota, Nebraska, Colorado, New Mexico, Texas and Oklahoma. It generally prefers sandy, disturbed soils. [4] The species is considered locally endangered within the state of Minnesota. [5] The species is also considered locally endangered within the state of Illinois. [6]
Polanisia jamesii is an annual herb with branched stems, producing pale yellow flowers on a terminal raceme. [7]
Threatened species are any species which are vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment without direct reference to human activity.
The Endangered Species Act of 1973 is the primary law in the United States for protecting and conserving imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation". The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed. It therefore "protect[s] species and the ecosystems upon which they depend" through different mechanisms. For example, section 4 requires the agencies overseeing the Act to designate imperiled species as threatened or endangered. Section 9 prohibits unlawful ‘take,’ of such species, which means to "harass, harm, hunt..." Section 7 directs federal agencies to use their authorities to help conserve listed species. The Act also serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The Supreme Court found that "the plain intent of Congress in enacting" the ESA "was to halt and reverse the trend toward species extinction, whatever the cost." The Act is administered by two federal agencies, the United States Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS). FWS and NMFS have been delegated by the Act with the authority to promulgate any rules and guidelines within the Code of Federal Regulations (CFR) to implement its provisions.
The Blanding's turtle is a semi-aquatic turtle of the family Emydidae. This species is native to central and eastern parts of Canada and the United States. It is considered to be an endangered species throughout much of its range. The Blanding's turtle is of interest in longevity research, as it shows few or no common signs of aging and is physically active and capable of reproduction into eight or nine decades of life.

Wolf Lake is an 804-acre (325.4 ha) lake that straddles the Indiana and Illinois state line near Lake Michigan. It is smaller than it was prior to settlement by European colonizers because of infilling for development around the edges. Despite years of environmental damage caused by heavy industries, transportation infrastructure, urban runoff and filling of wetlands, it is one of the most important biological sites in the Chicago region.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as Critically Endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.

It is also occasional in Florida waterways.
William W. Powers State Recreation Area is an Illinois state park administered by the Illinois Department of Natural Resources on 580 acres (230 ha) in the Hegewisch community area of the City of Chicago in Cook County, Illinois, United States.

Polanisia dodecandra is a species of flowering plant in the Cleomaceae family, known by the common name redwhisker clammyweed or clammyweed, and there are three subspecies of Polanisia. Usually annual, occasionally perennial, Polanisia is native to North America, and is found throughout much of Canada and the United States. It favors full sun, mesic to dry conditions, and barren, sandy or gravelly soils, even highly disturbed areas where there is little other ground vegetation. It looks similar to a close relative, the spider flower (Cleome).
Polanisia is a genus of flowering plants in the family Cleomaceae. Members of the genus are commonly known as clammyweeds. Polanisia jamesii is listed as locally endangered in Minnesota, while P. dodecandra is widespread through much of North America.
The Hackmatack National Wildlife Refuge is a newly established United States national wildlife refuge that will include noncontiguous properties, especially tallgrass prairie patches, wetland properties, and oak savanna parcels, located in the northwestern region of the Chicago metropolitan area and the southern part of the Milwaukee area.
