,. ~ . <br />There maybe absinth wormwood associated with the gravel pit and/or adjacent lands. <br />An inspection for absinth wormwood has not been done in the area of the gravel pit. <br />The wetland area needs to be monitored for oxeye daisy infestations. Oxeye daisy is <br />known to infest wetlands and riparian azeas. Canada thistle will also be on the perimeter <br />of the wetlands. <br />Every precaution should betaken when treating weeds near wetlands. Only herbicides <br />labeled for use near wetlands should be used. <br />IV. Management Actions -Integrated Plant Management (IPM) <br />Integrated plant management is a strategy using a comprehensive, interdisciplinary <br />approach to manage noxious weeds. The purpose of integrated plant management is to <br />achieve healthy and productive natural and agricultural ecosystems through a balanced <br />program. <br />The following control methods are standard components of an IPM program. While <br />these methods may be used singularly, they aze usually most effective when used in <br />combination. <br />A. Prevention <br />Prevention, early detection, and eradication of new noxious weed plants are the most <br />effective means of integrated plant management. Prevention is best accomplished by <br />ensuring that new weed species' seed or vegetative reproductive plant parts aze not <br />introduced on to the mining or wetland site. To do this, the following actions will be <br />taken: <br />Revegetation: <br />o Revegetate access roads and the perimeter of the pit to prevent noxious weeds from <br />becoming established. Seed utilized for revegetation will be certified weed free, <br />based on availability. A drill will be used to plant the seed where terrain allows; <br />otherwise the seed will be broadcast or hydroseeded. Seeding will be done in late <br />fall. <br />o Hydroseeding-the seed will be sprayed on first and then the mulch will be sprayed <br />on. This process ensures good soil to seed contact resulting in a successful seeding <br />project. <br />o Hay bales used for erosion control and/or mulch will be certified weed free. <br />o The slope on the west side of the pit will be revegetated to prevent further <br />erosion. The challenge will be getting enough top soil to stay on the slope to <br />provide a bed for the seed to become established and stabilize the bank. It <br />maybe necessary to use an erosion control blanket in addition to the <br />vegetation. <br />
