Often a primary objective is the elimination of existing vegetation, but this varies depending on the desired objective and the occurrence of existing prairie, wetland, woodland or shoreline plants. Different landscapes require different procedures. What is essential is to put the best combination of steps together to assure the best outcome.
Methods may include spraying, tilling, cutting, burning or planting cover crops. Key to determining the amount and type of required ground preparation is the existing condition and anticipated restoration of a site. Trees, brush, exotic grasses and even some native plants, need to be managed to create optimum planting conditions.
Because many sites, today, have been totally taken over by exotic species, they must be carefully cleared of existing vegetation to prevent soil erosion and protect any surrounding desirable plants.
There are usually several options that can be implemented sequentially to accomplish the job safely and successfully. PRI leads the industry in the development of these techniques and technology.
