Abstract/Contents: | "Vegetation management is a major component of the operational programs of both railroads and power company utilities. Railroads are required to maintain a vegetation-free zone along and within the track line. This is accomplished using a combination of pre-emergence and postemergence herbicide applications. Glyphosate is used extensively along with residual herbicides such as imazapyr and diuron. Vegetation is also maintained along the railroad easement, where a 12-inch height maximum is required. Many vegetation management schemes in this area are designed to promote bermudagrass (Cynodon dactylon). Mowing is used in residential areas, but chemical species control is employed whenever possible. Side-trimming of woody brush and trees along easement corridors is also chemically controlled with fosamine. The use of aerial application with helicopter is increasing due to logistical issues with personnel and downed track time. Vegetation management in power line rights-of-way has changed dramatically over the last 10-15 years. Prior management focused on periodic vegetation removal when conditions became critical to proper power transmission. Since then, vegetation is managed to promote grasses, forbs and low-growing, low density shrub species. Aggressive mechanical removal is employed as the initial step, followed by a broad-spectrum herbicide application the following year. Vegetation management is typically on a 3-4 year cycle, but this depends on regrowth rate and species. Mechanical control is gradually being replaced by chemical control methods due to cost effectiveness and selectivity. Aerial applications are not employed; all herbicides are applied on the ground via backpack sprayers, tractors, ATV's, etc. Side trimming and removal of danger trees remains a major concern, especially with the 2004 hurricane season. Substation vegetation control is entirely chemical based, utilizing a combination of pre-emergence and post-emergence herbicides. Nearly all vegetation management is contracted to private sources. There is an increasing level of herbicide selection and vegetation decision-making process is being regulated to the contractor, resulting in performance-based contracts that require >95% control. In addition, mowing and herbicide contracts are being combined into an overall vegetation management system." |
