Because significant natural community and species diversity is found in the area, it has been designated a state Resource Rich Area. This report is part ofa series ofreports on Illinois Resource Rich Areas where a public private partnership has been formed. These assessments provide information on the natural and human resources of the areas as a basis for managing and improving their ecosystems. The determination ofresource rich areas and development ofecosystem-based information and management programs in Illinois are the result ofthree processes -- the Critical Trends Assessment Program, the Conservation Congress, and the Water Resources and Land Use Priorities Task Force. Background The Critical Trends Assessment Program (CTAP) documents changes in ecological conditions. In 1994, using existing information, the program provided a baseline of ecological conditions. I Three conclusions were drawn from the baseline investigation: I. the emission and discharge of regulated pollutants over the past 20 years has declined, in some cases dramatically, 2. existing data suggest that the condition of natural ecosystems in Illinois is rapidly declining as a result of fragmentation and continued stress, and 3. data designed to .monitor compliance with environmental regulations or the status of individual species are not sufficient to assess ecosystem health statewide. Based on these findings, CTAP has begun to develop methods to systematically monitor ecological conditions and provide information for ecosystem-based management. Five components make up this effort: 1. identifY resource rich areas, 2. conduct regional assessments, 3. publish an atlas and inventory ofIllinois landcover, 4. train volunteers to collect ecological indicator data, and . 5. develop an educational science curriculum which incorporates data collection 1 See The Changing l/Iinois Environment: Critical Trends, summary report and volumes 1-7. iii At the same time that CTAP was publishing its baseline findings, the Illinois Conservation Congress and the Water Resources and Land Use Priorities Task Force were presenting their respective findings. These groups agreed with the CTAP conclusion that the state's ecosystems were declining. Better stewardship was needed, and they determined that a voluntary, incentive-based, grassroots approach would be the most appropriate, one that recognized the inter-relatedness ofeconomic development and natural resource protection and enhancement. From the three initiatives was born Conservation 2000, a six-year program to begin reversing ecosystem degradation, primarily through the Ecosystems Program, a cooperative process of public-private partnerships that are intended to merge natural resource stewardship with economic and recreational development. To achieve this goal, the program will provide financial incentives and technical assistance to private landowners. The Rock River and Cache River were designated as the first Ecosystem Partnership areas. At the same time, CTAP identified 30 Resource Rich Areas (RRAs) throughout the state. In RRAs where Ecosystem Partnerships have been formed, CTAP is providing an assessment of the area, drawing from ecological and socio-economic databases to give an overview ofthe region's resources -- geologic, edaphic, hydrologic, biotic, and socio-economic. Although several ofthe analyses are somewhat restricted by spatial and/or temporal limitations ofthe data, they help to identify information gaps and additional opportunities and constraints to establishing long-term monitoring programs in the partnership areas. The Mackinaw River Assessment The Mackinaw River begins near Sibley in Ford County and runs west to meet the lllinois River south ofPekin, Illinois. The boundaries ofthe Mackinaw River Area Assessment, as well as the Mackinaw River Ecosystem Partnership area, coincide with the boundaries ofthe Mackinaw River Basin. This area is situated along the roughly 125-mile river in the counties of Tazewell, McLean, and Woodford, with small sections in Mason, Livingston, and Ford counties. The Basin has 15 subbasins (identified by the Illinois Environmental Protection Agency) which cover approximately 1,138 me (728,495 acres). The land in the Panther Creek and the "middle" Mackinaw River subbasins, an area totaling 124,740 acres, was designated a state "Resource Rich Area" because it contains significant natural community diversity. The Mackinaw River Ecosystem Partnership was subsequently formed around this core area ofhigh quality ecological resources. This assessment is comprised oftwo volumes. In Volume 1, Land Cover Inventory provides an overview of the land cover in the region; Geology discusses the geology, soils, and minerals in the assessment area; Water Resources discusses the surface and groundwater resources; and Living Resources describes the natural vegetation communities and the fauna ofthe region. In Volume 2, the Socio-Economic Profile discusses the demographics, infrastructure, and economy ofthe area, focusing on the three counties with the greatest amount ofland in iv t 1 S08IIe 1:2700000 Dr.ln.go bllline from 1:24000 .cal.
