| Status and distribution of the bobcat (_Lynx rufus_) in Illinois | |
| 2000 Transaction of the Illinois State Academy of Science (93): 165-173 | |
We compiled data from a variety of hunter and trapper surveys and sighting records (n = 3,123) to provide a current record of bobcat (Lynx rufus) distribution and relative abundance throughout the state. A subset (n = 2,212) of these data was used to analyze regional and annual trends in abundance. Bobcats were sighted in 99 of 102 Illinois counties, and trends from multiple types of surveys suggested that abundance increased throughout the state during the 1990s, especially in the 16 southernmost Illinois counties. There were >30 reported sightings of bobcats from each of 17 counties which we defined as indicative of a high resident bobcat population. Counties with the most overall sightings were Union, Jackson, and Johnson. Only DeKalb, Piatt, and Stark counties had no sightings during the study period. We concluded that the bobcat was widely distributed in Illinois and no longer warranted classification as "threatened" as defined by the Illinois Endangered Species Protection Board. |
