Presbyterian Homes of Arden Hills <br />Preliminary Landscape Management Plan <br />Page 3 <br />number of trees less than 8 inches caliper size will remain as a part of preserved wooded areas on the <br />site. <br />Anticipated changes <br />While the intention is to protect as many trees in the wooded areas as possible, elements of the <br />proposed development may still impact tree resources. Most trees to be retained occur on the <br />periphery of the site, and in areas that will not be impacted by construction activities and will not likely <br />be subject to changes that will adversely affect the vitality of the trees. In essence, those trees indicated <br />to remain have a strong likelihood of becoming a part of the patterns of the landscape after <br />development— subject to their ability to withstand the presence of diseases and other factors that may <br />impact their health. <br />Management <br />In order to protect trees of value that will not be affected by the proposed development or construction <br />activities, and to preserve the long term integrity of woodlands outside of construction areas, <br />Presbyterian Homes proposes to undertake certain landscape management activities. The landscape <br />management strategy is predicated on three primary activities: <br />a. removal of trees and other vegetation that are not viable, that pose a hazard to humans or <br />other trees, that are considered invasive species, that might suffer from disease or <br />uncontrollable infestations, or that would promote the growth of more valuable species or <br />trees; <br />b. maintenance of existing trees, and defining proper maintenance for new trees; and <br />c. planting new trees and other plants that will ensure the long term viability of wooded area as <br />vegetative buffers between the proposed project and nearby homes, while offering habitat for <br />many of the wildlife species that might be found on the site today (or enhancing opportunities <br />for other desirable wildlife species). <br />a. Removal <br />Dead trees. Some trees that exist on the site are no longer living, but have not been removed. <br />This is a common practice for landscapes that include wooded areas similar to those found on <br />the site. Unless a dead tree poses a threat to nearby buildings, cars, or people, they are often <br />left in place, only to fall as they decay. However, if left to decay, they may pose a threat to <br />other more valuable species; in these cases, the landscape management plan encourages their <br />removal. <br />Hazard trees. Hazard trees are those trees that pose a threat to humans or to other trees. In <br />some cases, an entire tree might be removed, but the more common instance would be removal <br />of a limb or some portion of a tree. Hazard trees will be identified and removed as appropriate. <br />Invasive plants. The tree inventory notes the presence of several buckthorn, and visual evidence <br />indicates a significant number of small buckthorn plants. Buckthorn is identified on the State of <br />Minnesota's Invasive Species list as a noxious weed, and efforts will be made to remove it. <br />
