A walk in the woods
Our forest preserves in Kankakee County have some of the best wildlife viewing around. I went on two of the last nighttime moonlight outings that Jean led and was excited about what we heard and saw. Now, some might watch a scary movie or find a TV show interesting, but I would much prefer reality for a real adventure. As Forest Gump might say, "you never know what youíre going to git".
At Gar Creek Prairie, the coyotes howled and sent shivers up my spine. A recent attack chronicled in the Daily Journal on a pet owner made me glad my pet dog, Jasmine, was not along. Later in the dark, a screech owl whinny was heard. I thought I would try a Barred Owl hoot to attract my favorite night flier. Instead, a buck in rut grunted back and started running towards us. You could hear the antlers hit the branches as it got closer. Now, this got my hairs up on the back of my neck. A coyote is small, a buck is not. It came within a few yards and passed by unseen in the dark. You need your hearing to tell what is happening.
Another time in the dark at the Waldron Arboretum, we met a barking German Shepherd. Not knowing what to do, we froze. The owner was there and called out for his canine to be quiet. I donít know if running would have helped, but I was ready to tell my feet "donít fail me now!"
At Gar Creek Prairie the beavers are active well into night and a tail slap on the water has surprised me on more than one occasion. Woodcocks are also night fliers. One year they displayed over the prairie, the "peent" call and diving antics could just be herd and seen in the dimming light.
Daylight brings out the real avian performers in spring. Orioles, bluebirds, catbirds, and too many sparrow species to name call on the Gar Creek Prairie. It helps if youíre with others to point out what youíre missing. Thatís why I like the hikes on our nature preserves. Come and see itís so. Put the VCR to record that nature program and go for a walk in the woods.

Tracking Journal - Animal Tracks and Sign
A complete squirrel track on a maple leaf, a raccoon track on the only dollar sized patch of mud on a trail, the back foot of a woodchuck, the shine of a heavily used fox trail and the golf ball, full of teeth marks, that it tried to eat. The tracks of deer in the grass coming from the swamp then through the yard. The repetition of cat tracks.
The black logs, littered with travel, leaving their mud imprints and toes everywhere. The mice whose ability to reveal its wandering is limited only by your eyes and senses. The fresh coyote tracks, running parallel with the swiftly moving tracks of fleeing deer. The hairs of many animals on a mound of dirt made just right for peering. The scat on a log. The chew on a briar. The energy of a rub on a small pine.
The pointed toes of the rabbit. A broken hickory nut. The ankle high broken twig, the scratches on bark. The call of the first chorus frog. The sun through the bent branches of the trees, the wind in my face and the greetings of a chickadee. And tomorrow ...................
The Kankakee River and its Tributaries
The first section of this article is from portions of the Illinois Department of Natural Resources publication, "Kankakee River Area Assessment, volume 5; Early Accounts of the Ecology of the Kankakee River Area". Descriptions of the pre-settlement landscape of the Kankakee River Basin can be found in the accounts of early French traders and missionaries who used the river as a travel route between the Great Lakes and the Illinois River, as well as later surveyors, hunters and settlers in the Kankakee River Basin.
Restoration - Army Corps Recommendations
The second portion of this article is from the Illinois River Basin Restoration Comprehensive Plan from the Army Corps of Engineers. The engineers and restoration ecologists have put their best efforts in setting forth a plan to not only arrest the decline of Illinois River and its tributaries, but to restore and improve the watershed. The default, should no restoration plan be implemented, is continued deterioration of watershed quality, with all of the related consequences.
The next step in the process is for citizens to discuss the need for stewardship with their state and federal representatives so that the best plan is implemented and funds are appropriated to go forward with the restoration projects. The Army Corps plan calls for a 50- year period. With care and understanding, humans are capable of helping to restore balance to a damaged landscape much faster than were nature left on her own.

SIGNIFICANCE OF THE ILLINOIS RIVER BASIN
The Illinois Riverís significance was recognized by Congress in WRDA of 1986 as a "nationally significant ecosystem" as part of the Upper Mississippi River System. A 1995 report by the U.S. Department of the Interior lists large streams and rivers as an endangered ecosystem in the United States, with a documented 85 to 98 percent decline since European settlement. The Illinois River is one of a small number of world-class river floodplain ecosystems; where biological productivity is enhanced by annual flood pulses that advance and retreat over the floodplain and temporarily expand backwaters and floodplain lakes.
The predevelopment Illinois River floodplain was a complex mosaic of prairies, forests, wetlands, marshes, and clear water lakes. In the main stem river floodplain, the main channel threaded through a variety of connected and isolated backwater lakes, bottomland forests, prairies, marshes, and swamps.
The productivity of the predevelopment system was demonstrated by the millions of migratory birds that stopped to rest and feed on their migrations or stopped to nest in the floodplain marshes. The fishery was reputed to be vast and exceptionally large fish catches were common. At the turn of the century, the river produced 10 percent of the nationís catch of freshwater fish. The Illinois River system also supported more freshwater mussels per mile than any other river on the continent. The forests supported a higher diversity of trees, many that produced fruit and seeds. Todayís flora and fauna are but a remnant of these historic levels, but they still include some of the richest habitat in the Midwest, even some unique in North America.
Despite the ecological damage and degradation, the landscape and river system remain surprisingly diverse and biologically productive. The Illinois River basin is a critical mid-migration resting and feeding area of the internationally significant Mississippi River Flyway, utilized by 40 percent of all North American waterfowl and 326 total bird species, representing 60 percent of all species in North America. A survey conducted by the Illinois Natural History Survey in the fall of 1994 found that 81 percent of the fall waterfowl migration in the Mississippi flyway utilized the Illinois River. Twenty-six avian species are state listed as threatened or endangered; one of which is federally-threatened, the Bald Eagle, and four others are Federal species of concern. Many of these species are associated with wetlands or grasslands, and are also sensitive to landscape fragmentation.
The Illinois River system is home to approximately 35 mussel species, representing 12 percent of the freshwater mussels found in North America. Five mussel species are listed by the State of Illinois as threatened or endangered, one of which is a candidate for Federal listing. Fish diversity is similarly high, with 115 fish species found, 95 percent of which are native species. Many of these species require riverine, backwater, and floodplain habitat as part of their life cycle. Eighteen fish species are listed by the state of Illinois as threatened or endangered. Many of these species are endemic to the basin and/or intolerant of high silt levels. A group of aquatic organisms that is particularly representative of the Illinois River is the "Ancient Fishes" such as the paddlefish and sturgeon. The majority of these fish are migratory by nature and utilize a diversity of river habitats, flowing channel habitats, side channels, and backwater areas.
The Illinois River has long been a significant resource to the nation and the State of Illinois. It supported large Native American populations and provided a route for European explorers and settlers, and helped make the Midwest agricultural economy viable as early as the nineteen century. This waterway provides navigation from Lake Michigan and Chicago to the Upper Mississippi River, linking the inland waterway system with the Great Lakes. In 2004, 45 million tons of commodities were transported on the Illinois Waterway. The river and its tributaries provided water for residential and industrial users and also assimilated the wastes of burgeoning metropolitan communities. In Illinois, 90 percent of the stateís population, more than 11 million people, reside in the basin.
Local communities, counties, and non-governmental organizations have demonstrated commitment to the Illinois River, by implementing approximately 40 management plans calling for restoration of all or a portion of the Illinois River Basin. The Nature Conservancy and The Wetlands Initiative have both made major investments purchasing more than 11,000 acres of Illinois River floodplain and adjacent habitats for the purpose of restoration in recent years, adding to the approximately 135,000 acres already in State and Federal ownership in the basin. However, many of the restoration efforts have focused only on small components of the basin without considering the broader basin context, which is the focus of this comprehensive plan.
PROBLEMS AND SYSTEM LIMITING FACTORS
The Illinois River Basin has and continues to experience a loss of ecological integrity due to sedimentation of backwaters and side channels, degradation of tributary streams, increased water level fluctuations, reduction of floodplain and tributary connectivity, and other adverse impacts caused by intensive human development over the last 150 years. While many of the original plant and animal species are still present in the basin, but at reduced levels, the physical habitats (structure) and the processes that create and maintain those habitats (function) have been greatly altered. In total, these alterations have led to a decline in the ecological health to the point where aquatic plants beds have been virtually eliminated from the lower river; macro-invertebrate numbers have declined significantly; the loss of backwaters areas with sufficient depth for spawning, nursery and overwintering habitat is now considered limiting for many native fish; and floodplain, riparian, and aquatic habitat loss and fragmentation is a threat to the population viability of State and federally listed species in the basin. The following areas have been identified as the physical factors that limit system ecological integrity: excessive sedimentation; loss of productive backwaters, side channels, and islands; loss of floodplain, riparian, and aquatic habitats and functions; loss of aquatic connectivity (fish passage) on the Illinois River and its tributaries; altered hydrologic regime; water and sediment quality, and invasive species.
VISION AND GOALS
The vision for the Illinois River Basin, accepted by the Federal, State and local stakeholders involved in the development of the Illinois River Basin Restoration Program, is:
The interagency study team developed the Illinois River Basin system wide ecosystem restoration goals and objectives in direct response to the widely identified system limiting factors. Also included are proposed measures to address the limiting factors and their expected outputs. These goal categories are interrelated and improvements in all areas are needed to substantively improve ecological integrity. As efforts are undertaken across several goal categories, the restoration activities would reverse complex, systemic declines that have degraded the system below some critical thresholds.
Overarching Goal: Restore and maintain ecological integrity, including habitats, communities, and populations of native species, and the processes that sustain them
1. Problem: Excessive Sedimentation
Increased sediment loads from the basin have severely degraded environmental conditions along the main stem Illinois River by increasing turbidity and filling backwater areas, side channels, and islands. Similar problems can be seen throughout the basin where excessive sediment has degraded tributary habitats. The average amount of sediment delivered to the Illinois River each year is approximately 12.1 million tons; of which 6.7 million tons (55 percent) is deposited within the river, its bottomlands, and backwater lakes.
Goa1: Reduce sediment delivery to the Illinois River from upland areas and tributary channels with the aim of eliminating excessive sediment load
Measures. Incising channels would be treated with rock riffle structures, if possible, otherwise using sheet-pile grade control structures. The preferred method of treating bank erosion was assumed to be stone barbs, then stone toe or finally a stone armor blanket if necessary; bioengineering was incorporated in most of the bank erosion stabilization measures. Finally, upland sediment control measures include the construction of dry basins.

2. Problem: Loss of Productive Backwaters, Side Channels, and Islands.
A dramatic loss in productive backwaters, side channels, and islands due to excessive sedimentation is limiting ecological health, connectivity to the river, and altering the character of this unique floodplain river system. The Illinois River has lost much of its critical spawning, nursery, and overwintering areas for fish, habitat for waterbirds (including diving ducks), aquatic species, and backwater aquatic plant communities. On average, the backwater lakes along the Illinois River have lost 72 percent of their capacity.
Goal: Restore aquatic habitat diversity of side channels and backwaters, ... to provide adequate volume and depth for sustaining native fish and wildlife communities.
3. Problem: Loss of Floodplain, Riparian, and Aquatic Habitats and Functions.
Land-use and hydrologic change has reduced the quantity, quality, and functions of floodplain, riparian, and aquatic habitats. Flood storage, flood conveyance, habitat availability, and nutrient exchange are some of the critical aspects of the floodplain environment that have been adversely impacted. Habitat loss and fragmentation are widespread problems that, in the long term, could limit attempts to maintain and enhance biodiversity. In addition, habitat forming disturbance regimes have been altered, affecting habitat and species diversity. An analysis of the main stem Illinois River floodplain cover types reveals a loss of approximately 75 percent of the forest, 81 percent of the grassland, and 70 percent of the wetlands. In addition, nearly 50 percent of the floodplain has been isolated from the river. A similar analysis of the tributary floodplains reveals approximate losses of 16 percent of the forest, 36 percent of the grassland, and 70 percent of the wetlands. Channelization is estimated to impair approximately 1,400 miles of perennial stream within the Illinois River Basin.
Goal: Improve floodplain, riparian, and aquatic habitats and functions (Goal 3)
Measures. Potential measures for implementation cover a wide range of practices designed to improve floodplain, riparian, and aquatic habitats, including riffle structures, channelization remeandering, gated levees, wetland restoration (photograph ES-3), plantings (wetland, forest, prairie), and invasive species management.
4. Problem: Loss of Aquatic Connectivity (fish passage) on the Illinois River and Its Tributaries.
Construction of dams on the main stem and tributaries alters the temperatures, flow regime, sediment transports, chemical concentrations, and isolates biotic communities. As a result, aquatic organisms do not have sufficient access to diverse habitat such as backwater and tributary habitats that are necessary at different life stages. Lack of aquatic connectivity (fish passage) slows repopulation of stream reaches following extreme events such as flooding, drought, and pollution and reduces genetic diversity of aquatic organisms. There are seven dams on the Illinois waterway and approximately 467 within the basin where fish passage could be implemented.
Goal: Restore aquatic connectivity (fish passage) on the Illinois River and its tributaries, where appropriate, to restore or maintain healthy populations of native species.
Measures. Fish passage can be accomplished through a variety of techniques. These options include dam removal; rock ramp on the downstream face of the dam to provide a relatively flat 3 to 5 percent gradient; bypass channels; and Denil fishways, rectangular chutes or flumes with baffles extending from the sides and bottoms.
Outputs. The dams found throughout the Illinois River Basin block fish movement, but most dams are partially passable under some conditions. For native fish species, fish passage must be available during the appropriate times of the year or life stages, which is often not the case. Expected outputs would include improved fish access to spawning, nursery, and overwintering areas at appropriate times. Connectivity also allows for re-colonization and improved genetic diversity of populations of native fish and mussels.
5. Problem: Increased frequency and magnitude of water level fluctuations.
Basin changes and river management have altered the water level regime along the main stem Illinois River, stressing the natural plant and animal communities along the river and its floodplain. Land use chutes, the construction of locks and dams (which create relatively flat navigation pools), and isolation of the river main stem from its floodplain have all impacted the water level regime to varying extents. Two of the most critical results from the basin changes and river management, are the increased frequency and increased magnitude of water level fluctuations, especially during summer and fall low water periods. The lack of the ability to mimic natural hydrologic regimes in areas upstream of the navigation dams is also a problem. Increased flow variability has reduced the ecological integrity in tributary areas as well.
|Create 107,000 acres of storage area and 38,000 acres of infiltration area|
|Increase water level management at navigation dams|
|At an appropriate resolution, identify and quantify the land and drainage alterations that contribute to unnatural fluctuations and flow regimes|
|Draw down the pools at Peoria and La Grange for at least 30 consecutive days at least once every 5 years.|
Measures. Reducing peak flows and increasing base flows on the tributaries will be accomplished by increasing the volume of storm water storage in the watershed (through the use of various measures including: tile management, detention structures, and extended riparian areas) and directing storm water runoff to areas where it can infiltrate the soil and recharge groundwater (through the use of various measures including: tile management, filter strips, and grassed fields enclosed with a berm). Many of the detention and riparian areas will function as wetlands. Reducing fluctuations on the mainstem will be accomplished through the following measures including: performing pool drawdowns, installing automated dam gates, and installing new gates at existing dam sites were evaluated.
Outputs. In regard to tributary flows, regimes with reduced peaks and increased baseflows would provide more desirable levels of ecosystem function than currently occur. Within the tributaries, improved aquatic species survival is anticipated including, fish and macroinvertebrate populations. Like the tributary systems, two types of benefits were identified for the main stem: reduced fluctuations and area exposed by drawdown. In particular, the reductions in sudden water level rises in the summer is considered a critical element in restoring aquatic plant populations and reductions in rapid winter drops would protect native fish and other aquatic organism populations.
6. Water and Sediment Quality.
Water clarity is the primary factor limiting submersed aquatic plants. During periods of high turbidity, aquatic plant growth is limited, since suspended sediments interfere with light penetration into the water. In addition to turbidity, the quality of the sediments, particularly in the main stem, may limit macroinvertebrates such as fingernail clams. Water resources in the Illinois River Basin are also impaired due to a combination of point and non-point sources of pollution.
Goal: Improve water and sediment quality in the Illinois River and its watershed
Measures. Separate measures were not identified for the sole purpose of water and sediment quality restoration. However, benefits would result from reductions in sediment, nutrient processing in restored floodplain and riparian areas.
Outputs. It is expected that water quality would continue to improve somewhat in the future because of improved waste and storm water treatment practices and local conservation efforts, and that improved water quality would translate into improvements in other ecosystem components. However, future gains would be less dramatic than in the past without also working on the other limiting factors.

I did something a few weeks ago, that I hadn't done in many years. I collected a species from the wild and took it into my home. From a bordering ditch, I collected the tiny tadpoles of the early breeding chorus frogs. I wasn't sure why, for in an earlier day this would not have been unusual at all as I thought every order of animal was happy to share my living space with me.
From snakes to rats, hawks to ferrets, fish, rabbits, lizards, skunks......no species was spared from my observing and intruding glare as they were forced to share my residence with me. But that was long ago, a simple acknowledgement is usually all that is required now, but this time it was different. I collected their tiny sperm like bodies and put them into an old aquarium, making constant trips to the ditch to provide them with the fresh water they were accustomed to. Soon, I built them a small brooding pond next to the fish pond for them to wean in. They seemed happy and were growing larger and all was good. The other day I went to the ditch and noticed that the county had shoveled the ditch clean to allow the runoff to flow back into the swamp, leaving the banks filled with the bodies of most of the remaining tadpoles, and I then guessed that this is why I felt the need to collect these creatures after so many years. Great huh, ah the joy of positive intervention......
Until the other morning when I noticed a relatively tame buddy, (song sparrow), doing some collecting of his own from my newly built frog pond. The circle continues...........
We watched the Carolina Anoles down at my favorite spot this weekend. A male sitting low on a tree next to us, posturing with his red neck appendage to a female who had just walked across me to get next to him. Both of them bobbing their heads to each other in a beautiful and amorous display of courtship. The bird filled sounds of the wetland filling the air, a cool breeze flowing through the thick reeds. Suddenly the spell was interrupted by the squawk of one of the usually secretive blue jays, who quickly plucked a helpless anole from the crook of a tree overhead. The circle continues.........
The Tiger Salamander, growing up to 33 cm in length, is the largest terrestrial salamander native to Illinois. Its habitat is forests, woodlands, pastures, orchards, prairies and cultivated fields. The adults live on terra firma; in burrows, under logs, rocks or other cover. They are active at night, especially after a rain and during winter and breeding migration.
The Tiger Salamander persists, but is not abundant in areas disturbed by agriculture or development. As Illinois is one of the most highly modified environments in the world, like many other species, even though the Tiger Salamander is tolerant of disturbance, it is losing critical habitat. It is better able to persist than many other amphibians and reptiles of Illinois, as long as there are suitable breeding ponds remaining.
Fish-free ponds are required for breeding and larval life. During February Ė April, females attach eggs to twigs, leaves and plant stems under water in jelly-covered clusters of 20 Ė 50 eggs. Larvae grow rapidly and become significant pond predators. Larvae transform in late summer or autumn. Adult salamanders feed on beetles, centipedes, slugs, worms, and other invertebrates.
