Brush Clearing of old field areas: Clearing brush is a key activity early in this restoration process with removal of scattered boxelder and other trees and shrubs. This can take place weeks any time before herbicide/planting and is often best accomplished during fall and winter months. Cut small trees and brush so that no more than 1-3 inches of flat stump sticks up above ground surface. This will make it possible to drive equipment over the stumps and seed in those areas. Also, cutting brush and treating the stumps should be completed prior to the first prescribed fire. With the exception of eastern red cedar, treat tree and shrub stumps within one hour of cutting with a 25-50% solution of a glyphosate or picloram herbicide (trade names are Roundup and Garlon). Treating cut stumps by using a solution in a spray bottle allows for treating only the edge of the stump with minimal risk for damaging any adjacent desirable plants. Treating the stumps with an herbicide is important because it minimizes resprouting. Please note that herbicide application should be conducted while following the manufacturer's safety recommendations, including the use of appropriate protective equipment such as chemical resistant gloves and eye protection. These materials can be purchased at most hardware/home stores. Ideally, brush and tree limbs should be removed from the site or moved to the edge of the field. If necessary, cut brush should be piled and burned later. After drying sufficiently, piles can be burned during most times of the year after the material has had a chance to dry out, but winter is often the best. Snow cover greatly reduces the threat of the fire burning through adjacent grasses as well as reducing the chance for soil sterilization in addition to no need for a burn permit when there is more than three inches of snow on the ground. Control of Existing, Nonnative/V1/eedy Vegetation: Prior to seeding, the existing vegetation should be controlled. Before the herbicide is applied, a perimeter should be mowed around the field to allow for a prescribed burn break. Mowed areas that are to be used as firebreaks should be mowed at least 8-10 feet wide (see section below for more details on the construction of burn breaks). Control of existing herbaceous vegetation is most easily accomplished with the non- specific contact herbicide glyphosate (Roundup) mixed according to label directions (typically 3-6% solution). This activity may be accomplished by City staff, or with Top of the World Park Addition Natural Area Management Plan 17
