2000-2001 Illinois Trapper Report
A stratified random sample of 892 persons who purchased a 2000 resident Illinois trapping license was surveyed after the furbearer trapping season. The U.S. Postal Service was successful in reaching 857 of the licensees, 621 (72%) of whom returned usable questionnaires. Trapping license sales declined 9% from 1999 (2,345 licenses) to 2000 (2,126 licenses). Trappers had traps set for an average of 23.4 days during the 2000-2001 season, and they harvested an estimated 96,480 furbearers (down 18% from the 118,326 harvested in 1999-2000). Data are provided for temporal distribution of trapping activities, types of traps used, participation in trapper education programs, and fur hunting by trappers. The opinions of trappers as to changes in furbearer populations and trapping effort are also presented, as is a profile of personal characteristics of trappers.
2001-2002 Illinois Trapper Report
A stratified random sample of 894 persons who purchased a 2001 resident Illinois trapping license was surveyed after the furbearer trapping season. The U.S. Postal Service successfully reached 858 of the licensees, 619 (72%) of whom returned usable questionnaires. Trapping license sales increased 25% from 2000 (2,126 licenses) to 2001 (2,668 licenses). Trappers had traps set for an average of 29.8 days during the 2001-2002 season, and they harvested an estimated 184,562 furbearers (up 91% from the 96,480 harvested in 2000-2001). Data are provided for temporal distribution of trapping activities, types of traps used, participation in trapper education programs, sources of furbearer and trapping information, and fur hunting by trappers. The opinions of trappers as to changes in furbearer populations are also presented, as is a profile of personal characteristics of trappers.
2002 Illinois Light Goose Conservation Action Survey Report (2002)
Harvest of light geese during the 2002 Illinois Conservation Action was estimated at 17,875 geese, a decrease or 18,955 geese from the 2001 harvest of 36,830. Participation increased to 5,107 hunters during 2002 compared to 4,665 hunters during 2001. Hunters spent an estimated 31,204 days afield during 2002, a decrease of 1,430 from the 32,634 days hunted during 2001. Unplugged shotguns were the method used most often (67%); however electronic calls and hunting after sunset were also used by more than 50% of hunters (62% and 54%, respectively). As with hunters responding to the 2001 survey, hunters who did not participate in the conservation action reported no geese in the area and no place to hunt as well as not interested as the main reasons they did not hunt light geese.
2002-03 Illinois Trapper Survey Report [HR-03-02]
A stratified random sample of 770 persons who purchased a 2002 resident Illinois trapping license was surveyed after the furbearer trapping season. The U.S. Postal Service successfully reached 741 of the licensees, 551 (74%) of whom returned usable questionnaires. Trapping license sales increased 15% from 2001 (2,668 licenses) to 2002 (3,073 licenses). Trappers had traps set for an average of 28.1 days during the 2002-2003 season, and they harvested an estimated 193,072 furbearers (up 5% from the 184,562 harvested in 2001-2002). Data are provided for temporal distribution of trapping activities.
An Assessment of Metals Distribution and Transport in Groundwater Beneath the Diked Sediment Disposal Area, DePue Wildlife Management Area, Illinois [RR-110]
Potential toxic metal (Zn, Cd, Pb, Cu) contamination of groundwater at the periodically flooded DePue Dredged Sediment Disposal Area (DSDA), was assessed through the collection of groundwater and soil samples and water level data, geochemical modeling, and leaching and microcosm experiments. The median Zn concentrations in groundwater at three locations were between 2 and 5 mg/L. There was no evidence that contaminated groundwater has migrated offsite. Based on lake-sediment and soil data, the order of decreasing mobility in the site groundwater was Zn > Cu > Cd > Pb. Small amounts of Zn and Cd (< 2%) were leached from soil samples inside the DSDA in leaching experiments. About half of the dissolved Zn and Cd from groundwater samples can be accounted for by leaching, suggesting desorption was a major control for Zn and Cd. Chemical equilibrium calculations indicated that several reactions, including CdCO3 precipitation, coprecipitation of Zn with CaCO3, and sorption to ferric oxide, may retain the metals in the subsurface. Aqueous Zn concentrations were greatest in aerobic microcosms, lowest in sulfate-reducing microcosms, and intermediate in iron-reducing microcosms. Zinc would thus be expected to be most mobile in DePue soils during the early stages of flooding, when the soils are saturated but before conditions become anaerobic.
Asian Carp Rapid Response Workgroup to host Press Conference Call on Friday, November 13 (2009, November 12) [1576**09]
Press Release: The Illinois Department of Natural Resources and the Asian Carp Rapid Response Workgroup will host a conference call to talk about operational plans on the Chicago Sanitary and Ship Canal.
Cahokia Creek/Holiday Shores Lake watershed TMDL Report (2007, August) [IEPA/BOW/07-019]
This report documents the analysis and findings of the TMDL development for water segments within this watershed. Illinois is required to identify water bodies that do not meet water quality standards and to determine the Total Maximum Daily Load for pollutants causing the impairment.
Chicago Sanitary and Ship Canal to Close for Fish Barrier Maintenance (2009, November 13) [1583**09]
Press Release: A section of the Chicago Sanitary and Ship Canal is planned to be closed to all traffic, weather permitting, beginning December 2 for a period of four to five days. Fish toxicant to be used to prevent Asian carp from moving past barrier toward Lake Michigan.
Concentrations and Potential Toxicity of Metals and Ammonia in Peoria Lake Sediments and Pore Waters (covers Sampling period: April and October 2000) [RR-103]
The concentrations and potential toxicity of several heavy metals (cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn)) and ammonia in sediments and pore waters of Peoria Lake to 30 cm depth have been characterized.
Environmental Education Resources for Teachers
Environmental education covers a broad range of topics from recycling and pollution to natural resources and wildlife. Environmental education programs target all ages from preschool children to graduate students. This guide focuses on resources for teaching K-12 students about the environmental effects of pollution and waste and strategies for improving the environment. It also includes some industrial chemistry resources. This reference guide includes links to classroom activities, background and policy information, standards, and reference sources that teachers can use to develop their own environmental education lesson plans. Because the scope of the topic is so broad, this is not meant to be an exhaustive list. Rather, it is designed to give you some places to start looking for resources. Information to help you continue your research at your local library is included at the end of the guide.
