23 <br />4. Specifications for RestorationActivities <br />Thefollowing specificationsare general recommendations for how to conduct the types of work that could be done in the sitesof concern in this <br />document. Contracted work should further tailorthese specificationsto the work areasthey are being applied to. <br />Activity Park Management Specification <br />General notes on <br />activities <br />x Target Species are noted in the park-specific recommendation sectionswith example species listed to show the types of vegetation to <br />which each activity is geared. <br />Woody tree /shrub <br />initial removal <br />Example target species: Buckthorn (Rhamnus cathartica and Frangula alnus), amur maple (Acer ginnala), and black locust (Robinia <br />pseudoacacia) <br />x Mechanical harvest is to be carried out only during winter, when frozen soil conditions exist and at least 4” of snow cover exist on site. <br />All mechanical harvest operations will occur from December 1 – March 15. <br />x All stumps shall be cut as close to the ground as possible with a height above ground of 3 inches or less. <br />x All stumps will be treated accordingly to ensure no resprouts. See herbicide specifications for stump treatment. <br />x All trees harvested from the project area must be removed from the site. Trees can either be hauled directly off site or ground and <br />hauled off site. <br />Woody tree / shrub <br />control and <br />maintenance <br />Example target species: Buckthorn (Rhamnus cathartica and Frangula alnus), amur maple (Acer ginnala), and black locust (Robinia <br />pseudoacacia) <br />Cut and stump treat <br />x Brush near save trees, or in areas inaccessible to forestry mowers including sloped sections, will be cut by handheld tools (e.g. chain <br />saws or brush cutters). <br />x Cut/Slash will be allowed in those areas identified and it would not be conducive to forestry mowing, burning or hauling to a chipper. <br />Cut/slash material will need to be bucked up and dispersed so it makes ground contact. <br />x In areas of low density, cut material can be bucked up in pieces no longer than 4’, with no branches coming off the ground at <br />>45degrees, and dispersed in wooded areas not more than a single layer of material in depth and otherwise not impeding access and <br />mobility; and/or piled and burned. <br />Basal bark treatment <br />x Preferred treatment method for black locust under 4” dbh is to basal bark around the tree with an oil based triclopyr ester formulation <br />during appropriate weather conditions. <br />x Preferred treatment method for black locust over 4” dbh is to frill cut around the tree and treat the frill cut with Transline during <br />appropriate weather conditions.
