(Continued) Back into the Wild North American River Otter Once common in Illinois, habitat degradation and unregulated harvests caused populations of River Otter to decline dramatically by the mid-1800s and by the early 1900s they were considered rare in Illinois. Although, they were protected from hunting and trapping beginning in 1929, sightings were still uncommon. In 1989 otters were listed as state endangered, and IDNR developed recovery strategies that included reintroducing them into suitable habitats. More than 300 wild otters obtained from Louisiana were released into Wabash, Kaskaskia and Illinois River basins in 1994 -1997. Biologists American Black Bear closely monitored their population growth, and by 2004 they were American Black Bears were once common in Illinois but due to removed from state endangered status. By 2009 the state’s otter excessive, unregulated hunting were extirpated by 1870. There is population was estimated to be at least 11,000 individuals. currently no known resident population of black bear in Illinois. River otters currently live in every county in There are no plans to reintroduce black bears into Illinois, but Illinois, including McHenry County. Because the potential exists for individuals from Wisconsin and Missouri they are primarily nocturnal, sightings are not populations to travel into Illinois. If black bears enter McHenry common but signs of their presence like otter County, they would very likely be coming from Wisconsin. The scat, slides and footprints in mud and snow current Wisconsin population is estimated to be over 24,000 can be found in riparian zones. individuals with a higher density in the northern third of the state Pictured right: District trail cameras captured a family and lower densities southward.

While these success stories are encouraging, our work is not done— We need to continue our e昀昀orts to preserve critical habitat for all species and promote healthy ecosystems. At a time when pesticide use is higher than ever, both in agricultural and home garden use, let’s not forget our less charismatic wildlife species that need our help, especially insects. Both omnivores and carnivores depend on insects to eat and to feed lower trophic level prey for higher trophic level species such as raptors. Insects are critical food sources for nesting birds to feed their young. The loss of insects impacts all wildlife species. The loss of pollinator insects also reduces the viability of some plant species. Mosquito fogging is marketed to kill mosquitoes without mentioning the impacts to other insects with this non-target, general insecticide. We may have forgotten the lessons learned in Rachel Carson’s “Silent Spring” but if this trend towards eliminating 6 insects continues, we will have no choice but to respond before it is too late.
