1. Assess landowner’s goals regarding land use and subsequently, their acceptance, use and adaptation of alternative policies, policy instruments and/or technologies available to them. 2. Estimate the economic and financial impacts of alternative natural resource, environmental and agricultural programs and technologies on land - based firms and associated sector and regional economies. 3. Develop decision support systems and other policy instruments that will allow landowners and policy makers to more efficiently mitigate risks associated with rangeland management and to more efficiently achieve societal and landowner goals and objectives.

Pestman is a ranch-level, web-based decision support system (DSS) that integrates two primary analytical tools. These tools provide for 1) projecting forage and livestock production over several years into the future for specific sites/plant communities under specified alternative brush/weed control practices/programs and 2) analysis of firm (ranch) level economic/financial consequences of alternative brush/weed control practices/programs. Currently, the web based system has been developed for Texas and New Mexico and has undergone extensive testing by external experts and potential users. Planned enhancements include facilitating user entered herbicide costs and the capability of analyzing control alternatives for specified mixed brush species. Use Mail surveys and focus group meetings to assess landowner attitudes concerning participation in incentive-based programs designed to encourage land use practices that enhance various ecosystem services like surface and ground water supply, wildlife habitat, carbon sequestration and forage production for livestock. Quantify the impacts of Ashe Juniper removal and management on rangeland water yield, wildlife habitat and forage production for livestock in selected regions of Texas. Specific land uses, production practices and costs and returns budgets for land based enterprises will be documented along with costs of brush control and other restoration practices. Use PHYGROW (a hydrologic-based, rangeland forage production simulation model) ; fire behavior simulation models and real-time, spatially specific satellite generated weather data to continue enhancement of the Burning Risk Advisory Support System for grazinglands (BRASS-G). The BRASS-G system is designed to characterize fire fuel conditions and provide advisories regarding spatially specific suitability conditions for prescribed burning and wildfire risk. Use PHYGROW to continue enhancement of Forage Risk Assessment Management System (FRAMS) to provide web-based decision support to grazingland-based livestock producers. FRAMS includes components to assist producers in monitoring and mitigating herd nutrition, monitoring forage production and matching forage demand with supply, analyzing reproduction alternatives and nutrition - reproduction interaction and assessing economic trade-offs regarding herd management. Continue enhancement of crop insurance programs for Pasture and Rangeland (Forage Loss) utilizing a Seasonal Growth Constrained Rainfall Index and a NDVI Index in the United States. The programs allow for calculation of a percent deviation from normal rainfall (NDVI) and correspondingly, forage production and provides the basis for different levels of insurance coverage and the trigger mechanism to define a basis for claims. The programs allow users in spatially specific areas to obtain coverage for the specific type and value of forage growing on their land and offers them alternatives as to the amounts of forage loss they want to insure against.
