Landscape Tree Inventory and Management Plan for the United Company Corporate Campus, Bristol, Virginia
MetadataShow full item record
The United Company’s corporate headquarters resides on 65 acres in a residential area just east of downtown Bristol, Virginia. The main office complex on the south side of campus is accented by a mixed landscape of trees, shrubs, and lawns. In 2008, foresters with Virginia Cooperative Extension and Virginia Tech were contracted to develop a landscape tree management plan for the corporate campus. A complete tree inventory was conducted in summer 2008 to assess campus tree composition and maintenance needs. The inventory provided the basis for developing the management plan, which describes the priorities, goals, and objectives that should guide landscape tree management on the United Company corporate campus over the next decade and beyond. The inventory enumerated 630 landscape trees consisting of 67 different species. Flowering dogwood, yellow-poplar, and eastern white pine were the three most abundant species, each accounting for about 15% of the total population. The campus landscape is dominated by mature and geriatric trees. Despite the “graying” of the tree population, it is in fair to good condition overall. Structural defects that may threaten tree stability were commonly observed in the inventoried trees. Fortunately, most of these defects were mild to moderate and do not pose a significant threat to the landscape. However, critical defects were observed in several trees and should be attended to immediately. An assortment of disorders that may threaten tree health were also observed in campus trees. Prevalent disorders included trunk wounds, soil compaction, buried root collars, and inadequate mulching. These disorders can threaten tree health and should be addressed through a systematic tree maintenance program. In this paper, general recommendations for tree planting, maintenance, and removal are provided based on the primary goal of attaining a safe, attractive, and sustainable campus forest. In addition, specific management recommendations are provided for 11 critical-priority trees, 8 notable trees, and 3 prevalent species groups. Finally, an appendix has been assembled at the end of this report to provide definitions on common tree care terms and guidance on common tree care practices.
