effective methods of controlling salt cedar and Russian olive trees. (2) PROJECT REQUIREMENTS.—The demonstration projects under paragraph (1) shall— (A) be carried out over a time period and to a scale designed to fully assess long-term management strategies; (B) implement salt cedar or Russian olive tree control using 1 or more methods for each project in order to assess the full range of control methods, including— (i) airborne application of herbicides; (ii) mechanical removal; and (iii) biocontrol methods, such as the use of goats or insects; (C) individually or in conjunction with other demonstration projects, assess the effects of and obstacles to combining multiple control methods and determine optimal combinations of control methods; (D) assess soil conditions resulting from salt cedar and Russian olive tree infestation and means to revitalize soils; (E) define and implement appropriate final vegetative states and optimal revegetation methods, with preference for self-maintaining vegetative states and native vegetation, and taking into consideration downstream impacts, wildfire potential, and water savings; (F) identify methods for preventing the regrowth and reintroduction of salt cedar and Russian olive trees; (G) monitor and document any water savings from the control of salt cedar and Russian olive trees, including impacts to both groundwater and surface water; (H) assess wildfire activity and management strategies; (I) assess changes in wildlife habitat; (J) determine conditions under which removal of biomass is appropriate (including optimal methods for the disposal or use of biomass); and (K) assess economic and other impacts associated with control methods and the restoration and maintenance of land. (f) DISPOSITION OF BIOMASS.— (1) IN GENERAL.—Not later than 1 year after the date on which funds are made available to carry out this Act, the Secretary, in cooperation with the Secretary of Agriculture, shall complete an analysis of economic means to use or dispose of biomass created as a result of removal of salt cedar and Russian olive trees. (2) REQUIREMENTS.—The analysis shall— (A) determine conditions under which removal of biomass is economically viable; (B) consider and build upon existing research by the Department of Agriculture and other agencies on beneficial uses of salt cedar and Russian olive tree fiber; and (C) consider economic development opportunities, including manufacture of wood products using biomass resulting from demonstration projects under subsection (e) as a means of defraying costs of control. (g) COSTS.—
