At the dawn of the 20th century, most of Illinoisï¿½ 26,000 miles of stream sand rivers has sinuous courses with associated rich marshes and swamps. The stream banks were lined with protective vegetation that reduced the likelihood of bank failures and heavy erosion. Since then, agriculture and development have drastically reduced the health of our streams. The Streams Campaign is working to identify focal species and promote actions that improve habitats and reduce stressors for these species. Measuring progress
Goals and Actions
1. Develop and promote upland agricultural practices that decrease the energy, sediment load,
temperature, and pollutant load of drainage waters
a. establishment of native perennial vegetation on highly erodible soils
b. use of buffer vegetation at land-water transitions
c. wetland enhancement and restoration
d. conservation tillage or no-tillage practices
e. precision nutrient applications
f. limiting livestock access to streams
g. water control structures on subsurface tile drains for seasonal use
h. continued protection of stream waters and groundwater from nitrates, bacteria and
other contaminants derived from livestock waste
2. Develop and promote practices that decrease the energy, sediment load, temperature, and
pollutant load of drainage waters from developed (urban, suburban) lands
a. wetland enhancement and restoration, and other tools for flood water retention; use
retention facilities to hold floodwaters for an adequate length of time
b. minimizing impervious surfaces
c. zoning guidelines to promote smart growth and minimize effects on environmentally sensitive
lands (e.g., highly erodible soils)
d. maintenance and improvement of wastewater treatment facilities
e. appropriate nutrient applications on landscaped vegetation
3. Protect, restore and enhance near-stream and in-stream habitats and processes
a. restore and manage grassy buffers, wetlands, riparian forests, and flood plains
b. restore tributary streams to reduce head-cutting and sediment transmission to large rivers
1. buffer and restore channels of the Vermilion (Wabash), Embarras, and Little
Wabash rivers and their tributaries to benefit the high diversity of aquatic Species in
Greatest Need of Conservation in the Wabash River Natural Division
2. restore and manage the Wabash River, the largest unchannelized andunimpounded
river in Illinois
3. buffer and restore channels in 8-10 small headwater stream segments >5miles to
support listed fishes and mussels in each the Northeastern Morainal, Grand Prairie, Rock
River Hill Country, Wisconsin Driftless, and Illinois River and Mississippi River Sand
Areas natural divisions
c. re-meander channelized streams; provide technical assistance, publish and market to drainage
districts best practices that reduce erosion and improve habitat while lowering costs
d. re-establish and maintain connectivity of the main stem, main stem-tributary, channelfloodplain,
and channel-backwater on rivers and streams where appropriate
e. restore normal flood-pulse and hydrologic patterns
1. remove the dramatic water level changes associated with operation of wicket dams
2. reduce low-water fluctuations where possible, concentrating on the months of May
3. reduce peak flows by 2 to 3 percent for 2- to 5-year recurrence storm eventsï¿½this
will help to reduce peak flood stages and reduce high-water fluctuations along the river
f. dredge sediments where necessary
g. compact sediments to improve substrate conditions for aquatic plants, fish, and wildlife
h. restore and rehabilitate backwaters to a diversity of depths (5% >9 feet, 10% 6-9 feet,
25% 3-6 feet, and 60% <3 feet)
i. remove unnecessary dams and fit necessary dams with effective fish passage structures
j. restore and maintain side channel habitats
k. regulate reservoir releases to assure seasonal inundation of oxbows and backwaters
and to maintain the integrity of floodplain forests
4. Restore populations of imperiled and extirpated aquatic animals
a. maintain populations at all currently-occupied locations and re-establish populations
at 50% or more of historic locations where suitable habitat persists or can be restored.
The recovery of aquatic endangered and threatened animals will depend on restoration
and enhancement of existing aquatic habitats, such as pools, riffles, and lateral
wetlands. It will be necessary to re-create wetland habitats for amphibians and dragonflies.
1. protect and enhance Round Pond for the river cooter and other reptile species
2. protect the Vermilion River (Illinois), lower Fox River and tributaries for benefit of
listed redhorse species

well-vegetated streams supporting unique fish communities
5. restore coolwater streams, particularly within the Apple and Rock River watersheds
b. reintroduce native species into stream habitat where decimating factors have been
eliminated and natural recovery is unlikely
c. collaboration among the Illinois Endangered Species Protection Board, Illinois Department
of Natural Resources, U.S. Fish & Wildlife Service and other agencies, organizations and
institutions on recovery plans and actions for rare and declining species
5. Prevent and control invasions of detrimental exotic species
a. implement Rapid Response plans for the Great Lakes basin and Mississippi River
basin, covering all of Illinois

including all Grade A and B Illinois Natural Areas Inventory sites, in all natural divisions within
which they occur
7. Fill information gaps and develop conservation actions to address stresses
a. understand baseline conditions of system functioning and sustainability, against which
change can be measured
b. identify and address system-wide limiting factors for representative native species or
communities, including, but not limited to, altered natural disturbance regimes (hydrology,
connectivity, etc.), excessive sedimentation, reduction and fragmentation of aquatic and
riparian habitat (habitat patch size, habitat spacing, lateral and longitudinal connectivity),
water and sediment quality problems, and invasive species
c. develop flow standards for all rivers
d. evaluate drainage maintenance procedures in Illinoisï¿½ rivers to protect important remnant
habitats and avoid stream bed erosion

Mussel Project ï¿½ Freshwater mussels are one of the fastest declining taxonomic groups of organisms in North America, yet few consistently collected mussel-community data sets exist in Illinois. With State Wildlife Grant funding, we have collected baseline mussel data in conjunction with existing basin surveys on wadeable streams and other high priority locations in Illinois. To date, over 1050 sites in Illinois have been sampled and the results have been summarized in basin reports.
Coolwater Streams ï¿½ Temperature is one of the primary factors that determine the distribution of aquatic species. Although the predominant aquatic organisms in Illinois favor warmwater conditions, some coolwater obligate species are present (e.g. mottled sculpin and brown trout), which indicates the presence of cool streams. The goal of this study was to survey those cool streams and characterize stream thermal types to develop rapid methods (surrogates) for identifying stream temperature.
Temperature and stream characteristics (both biotic and physical) were collected at more than 350 stream locations and approximately 37% of those were identified as cool. Four fish species (mottled sculpin, brook stickleback, longnose dace and brown trout) were classified as coolwater obligates. Estimation of groundwater inputs to a stream, baseflow conditions and hyporheic temperature profiles were physical features that related to stream temperature. Using collected temperature information, we were able to construct a model that predicted temperature in streams throughout the state, and this model is 78% accurate at placing a stream into the correct thermal category. The combination of model outputs and identified characteristics can be used to classify stream temperature throughout the state.
Fish Species in Greatest Need of Conservation - Within the Wildlife Action Plan, fish Species in Greatest Need of Conservation (SGNC) are evaluated using information from the IDNR and INHS fish databases and a small number of experts. The goal of this study was to reevaluate status of these species by incorporating new data. Specifically, this study reconstructed fish SGNC tables (Appendix I and II of the Plan) using more recent data from a larger body of sources, included opinions from additional experts and evaluated the species in a quantitative and repeatable manner. These revisions will be included in the Action Plan revision, which will be completed in 2015.
Each fish SGNC was reevaluated using the eight listing criteria in Appendix I by analyzing data from seven fisheries databases, 31 fisheries experts and pertinent literature. Emphasis was placed on assessing trends in abundance and distribution. Stresses (Appendix II) were reevaluated with expert opinion and literature. This new evaluation process resulted in changes to 35% of listing criteria in Appendix I and 73% of stress assessments in Appendix II, largely because efforts were made to complete missing information in the original Plan appendices. An additional product of this study was the completion of distribution maps for all fish SGNC.
