Agricultural Wetland Banking
Agricultural wetland banking is a subset of the overall wetland banking system. The "ag bank" is solely for replacing wetlands impacted on agricultural lands for agricultural purposes. It cannot be used for projects that convert agricultural land to a non-agricultural use or projects that convert non-agricultural land to agricultural land. A summary of the differences between the ag bank and other banks ("regular bank") is provided as follows.
The use of the ag bank is governed by the following Memorandum of Understanding (MOU) between BWSR and the Natural Resource Conservation Service (NRCS). This MOU also establishes a Wetland Conservation Act (WCA) exemption for agricultural activities on agricultural land that is subject to the Swampbuster provisions of the federal farm program. This exemption is authorized in this manner per WCA rules 8420.0420 Subp. 2 G.
The bank service area restrictions do not apply to agricultural wetland banks established prior to the effective date of the MOU. The following file lists the banks that are "grandfathered in" and applicants are allowed to purchase credits from them for use within any <80% pre-settlement area without an increase in replacement ratio.
The following documents provide information and guidance on site selection, evaluation, review and crediting for establishing agricultural wetland banks.
BWSR has developed a web calculator Ag Bank Evaluation Tool Web Calculator for the above Ag Bank Evaluation Tool. Answers to the questions should be entered into the tool for calculation of resulting functional level scores.The tool and resulting scores should be used in conjunction with the above Ag Bank form Previously Restored Wetlands Guidance dated 4/19/12.
