    Withdrawn Rationale:

    This guide covers assisting wetland managers by prescribing a sequence of steps for defining and assessing wetland functions. This guide also identifies properties that must be considered in the selection of a wetland assessment procedure to determine whether it will assist in satisfying the requirements of wetland regulatory programs or produce valid design criteria for planned wetlands, or both. This guide can help wetland managers use existing assessment procedures more effectively during the decision-making process. The outcome of the assessment is dependent on many factors including the selected procedure, the sampling design, and assumptions; therefore, decisions and assumptions made should be documented throughout the process. While this guide is developed to assist in satisfying the requirements of wetland regulatory programs, it can also be used in a variety of planning, management, and educational situations.

    Formerly under the jurisdiction of Committee E50 on Environmental Assessment, Risk Management, and Corrective Action, this guide was withdrawn in January 2007 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

    1. Scope

    1.1 This guide covers assisting wetland managers by prescribing a sequence of steps for defining the assessing wetland functions. This guide also identifies properties that must be considered in the selection of a wetland assessment procedure to determine whether it will assist in satisfying the requirements of wetland regulatory programs or produce valid design criteria for planned wetlands, or both. This guide can help wetland managers use existing assessment procedures more effectively during the decision-making process. The outcome of the assessment is dependent on many factors including the selected procedure, the sampling design, and assumptions; therefore, decisions and assumptions made should be documented throughout the process. While this guide is developed to assist in satisfying the requirements of wetland regulatory programs, it can also be used in a variety of planning, management, and educational situations.

    1.2 The guide is not intended for use in assigning values to wetland functions in terms of economic (for example, dollars) or other value units. However, the information that is gathered while assessing wetland functions may be useful in meeting this objective when used in conjunction with other information (for example, see Refs (1) and (2)).

    1.3 This guide applies to assessment procedures designed for application at the ecosystem scale. It does not address the less commonly used landscape level models or the use of wetland assessment procedures for cumulative impacts analysis (3-5).

    1.4 Limitations-This guide does not include a standard wetland assessment procedure or models for assessing function. This guide has been written primarily to complement and to aid in the selection of current procedures. There are several procedures for quantifying wetland functions and each has been developed for specific purposes. The suitability of a procedure depends on assessment objectives, wetland type, availability of applicable models given the wetland type and objectives, and policy of local decision makers. There are continuous efforts to develp new and improved methods that could override any one recommended standard practice.

    1.5 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.

    1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
