The plan shall be prepared by a qualified wetland biologist and ehall include a planting plan which uses native species found in the adjacent eatablished wetland areas. To the maximum extent possible, cuttings from wetland vegetatton on site shall be used for propagation of mitigation plants. The monitoring plan shall contain a • hypothesis anJ clearly stated goals and criteria; the plan ehall monitor vegetation miz and caverage, wildlife usage, hydrology, � water qua11.'.y, hydric soils, and invertebrates.
