January 2009 TREE SHRUB SITE PREPARATION 0B PRACTICE INTRODUCTION 1B USDA, Natural Resources Conservation Service―Practice Code 490 2B TREE/SHRUB SITE PREPARATION pests, hinder needed equipment operation, Tree/shrub site preparation is the treatment of areas or create undue fire hazard to encourage natural regeneration of desirable trees Control of erosion and/or runoff and shrubs or to provide optimum site conditions Cost-effectiveness of chosen method for planting or direct seeding of desirable woody species. Protection of cultural resources, springs, seeps, wetlands, and other unique areas PRACTICE INFORMATION 3B Impacts on wildlife habitat This practice applies to understocked areas, areas planned for tree planting following harvest, areas COMMON ASSOCIATED PRACTICES 4B where a land cover change to woody plants is Tree/Shrub Site Preparation is commonly used as desired, or areas having undesirable vegetation that part of a Conservation Management System and inhibits or competes with preferred woody species. typically precedes Tree/Shrub Establishment (612). Other associated practices may include Upland The purpose of the practice is to prepare the land Wildlife Habitat Management (645), and for establishing a stand of desirable woody Windbreak/Shelterbelt Establishment (380). vegetation by controlling undesirable vegetation, removing slash and debris, or altering site For further information, refer to the practice conditions. Application of this practice requires standard in the local Field Office Technical Guide consideration of: and associated practice specifications and job Protection of existing desirable vegetation sheets. Treatment of remaining slash and debris so it does not harbor harmful levels of The following page identifies the effects expected to occur when this practice is applied. These effects are subjective and somewhat dependent on variables such as climate, terrain, soil, etc. All appropriate local, State, Tribal, and Federal permits and approvals are the responsibility of the landowner and are presumed to have been obtained. Users are cautioned that these effects are estimates that may or may not apply to a specific site.

The diagram above identifies the effects expected to occur when this practice is applied according to NRCS practice standards and specifications. These effects are subjective and somewhat dependent on variables such as climate, terrain, soil, etc. All appropriate local, State, Tribal, and Federal permits and approvals are the responsibility of the landowner and are presumed to have been obtained. All income changes are partially dependent upon market fluctuations which are independent of the conservation practices. Users are cautioned that these effects are estimates that may or may not apply to a specific site.
