CHAPTER 3 OBJECTIVES Nine objectives are being implemented to achieve the wetlands goal The action items identified to achieve these objectives are outlined in Chapter 6 Most of the Objectives and Action Items have remained the same since the First and Second Editions of the Strategy because the lnteragency Wetlands Committee recognized the validity ofthese objectives and the need fortheir continued implementation Two goals were combined in this edition based on their shared focus on information gathering Several action items were removed from this edition as they have been completed Removed action items are summarized in Appendix K The nine objectives currently being implemented are below 1 Characterize the state s wetlands resource base more completely and identify the critical functions of the major types of wetlands in each physiographic province Planning regulatory and restoration program managers need to understand the critical functions of major types of wetlands in order to better understand the need for and methods of maintaining and enhancing these critical functions In order to allocate scare program and nancial resources intelligently the State must consolidate existing information and collect additional information to complete an accurately located and characterized inventory of its wetland resources Furthermore planning regulatory and restoration program managers need to identify and understand the critical functions of major types of wetlands in orderto maintain and enhance these critical functions 2 Identify and prioritize unique exceptionally high quality or scarce wetland community types and sites for acquisition or other equally effective protection Certain unique highquality wetlands deserve a higher level of protection because ofthe public benefits and ecological functions they provide Examples of exceptional wetlands include wetlands that provide habitat for a threatened or endangered species or ecosystem wetlands that represent a rare type in Tennessee and wetlands that are of special value because of their function As a result of implementation ofthe Strategy unique wetlands are now being identi ed acquired or othenNise protected before development conversion or other adverse changes in land use are proposed 27 A systematic review and analysis of existing data and literature on Tennessee wetlands has yielded a database of candidate acquisition sites The acquired information can now be used by several state federal and non pro t programs to establish priorities and allocate available resources for acquisition or less than fee protection 3 Identify priority wetlands restoration sites in each river corridor and explore appropriate restoration methods for each wetland type including the restoration of natural flood plain hydrology This objective is intended not only to target suitable sites for restoration but to identify opportunities to restore the biological integrity of river corridors at the landscape level including consideration of corridors continuity and patch size Identification should be site speci c and representative of landscape types The candidate sites should be organized according to hydrologic units watersheds or existing basin authorities The process should also identify prime farmland recognize its value for agricultural production and considerthis factor in assigning priority as a restoration site The behavior of water the hydrologic regime is the engine that drives wetlands function Our understanding of the natural hydrology of oodplains and the interactions ofrivers lakes and aquifers with associated wetlands is incomplete and should be systematically addressed by a cooperative research program tailored to meet state wetlands information needs Projects including demonstration of techniques for restoring or maintaining natural oodplain hydrology should also include sufficient monitoring and follow up work to permit an assessment of the effectiveness and transferability ofthese techniques A demonstration restoration project will begin in 1998 at Stokes Creek to evaluate the effectiveness of current restoration techniques Both baseline and postproject monitoring data will be used to evaluate the success of this demonstration As our understanding grows every opportunity to restore natural meandering watenNays without arti cial levees should be pursued It is not the intent of this objective to ll in existing canals or to dredge all streams to historic elevations Restoration work should be targeted to those instances where a river system is attempting to reestablish a stable equilibrium and a relatively small intervention would reinforce or enhance the natural process and restore hydrology 4 Restore 70000 acres of wetlands by the year 2000 This objective calls for the restoration of approximately 10000 acresyear from 1993 through 2000 or about a 10 gain in the acreage reported by Hefner and Brown 1984 It should be clearly understood that the objective targets restoration of marginal cropland to a functional wetland it does not seek to affect prime agricultural land Prime candidate restoration sites overlap but do not coincide with priority acquisition sites Restoration projects should be designed and carried out by each agency according to its mission 28 Information will be shared and work coordinated by TEPO and IWCTWG 5 Achieve no overall net loss of wetlands acreage and functions in each USGS hydrologic unit While individual projects may result in gains in some wetlands and offset losses in others the result of the full array of programs will be no further loss of function in any hydrologic unit Priority is given during this edition of the Strategy to collecting adequate data to measure progress toward achieving this goal Many state agencies generate or collect data on wetlands functions related to their specific programs such as waterfowl habitat or water quality However there is currently no single state agency or program specifically charged with the continuing responsibility to compile all available qualitative and quantitative data on Tennessee wetlands or to collect new data where it is lacking Nor is any agency directed to establish a clearinghouse and archive to assess the status ofthe state s wetlands resources and monitor trends over time An additional permanent staff member will be needed to develop and administer a permanent program to receive compile collect and correlate wetlands data to carry out periodic status trends analyses and to prepare reports 6 Increase the level of benefits to landowners The majority of Tennessee wetlands occur on private land It is critical that landowners understand and bene t from the functions wetlands provide on their land Enhancing these bene ts will encourage voluntary wetland protection Education technical assistance and incentive programs may achieve this objective The sound and productive management of wetlands by private landowners will also assure that the public benefits ofwetlands will be sustained 7 Create more urban riparian areas wetland greenbelts and wildlife corridors The primary threats to wetlands in and near urban areas are land development construction and associated road building As an alternative to development wetlands can become a community asset ifthey are incorporated into an urban green belt plan park or wildlife corridor and dedicated to lowimpact recreational use andor storm water management 7 Increase wetlands information delivery to local governments the public and schools Many critical wetlands decisions are made by local planning commissions and elected officials these decisions are subject to public scrutiny It is important to provide current information on the local wetlands resources to these communities to ensure informed resource management decisions This will be especially important during this implementation phase as local governments work to meet new planning requirements set by the Tennessee General Assembly The State should encourage local communities to protect wetlands functions orto incorporate wetlands and oodplains into conservation 29
