(b) The objective of the plant materials activity is to select or develop special and improved plants and techniques for their successful establishment and maintenance to solve conservation problems and needs related to:
- (1) Controlling soil erosion on all lands;
- (2) Conserving water;
- (3) Protecting upstream watersheds;
- (4) Reducing sediment movement into waterways and reservoirs through the stabilization of critical sediment sources, such as surface mined lands, highway slopes, recreation sites, and urban and industrial development areas;
- (5) Stabilizing disposal areas for liquid and solid wastes;
- (6) Improving plant diversity and lengthening the grazing season on dryland pastures and rangelands;
- (7) Managing brush on mountain slopes with fire-retarding plant cover to reduce the possibility of fires that threaten life and property, or result in serious sediment sources;
- (8) Improving the effectiveness of windbreaks and shelterbelts for reducing airborne sediment, controlling snow drifting, and preventing crop damage from wind erosion;
- (9) Protecting streambank, pond, and lake waterlines from erosion by scouring and wave action;
- (10) Improving wildlife food and cover, including threatened and endangered and pollinator species;
- (11) Selecting special purpose plants to meet specific needs for environment protection and enhancement;
- (12) Selecting plants that tolerate air pollution agents and toxic soil chemicals;
- (13) Selecting plants that mitigate odor, Particulate Matter (PM)-10, and PM-2.5;
- (14) Testing plants for biofuels and other energy-related activities; and
- (15) Evaluating plants and techniques to combat invasive plant species and for reestablishment of desirable species after eradication.
