Impacts
Western Region Arid Southwest Crop Losses Work Group These data and this Work Group serve to address any Federal, regional, state, and local requests for information on the impact of insects or insecticides on our key crops. During this project term, we responded to 10 information requests, and used Crop Pest Losses data in about one third of our responses. Formal responses are posted on the Arid Southwest IPM Network website at http://ag.arizona.edu/apmc/Arid_SWPMC_Info_Requests.html. What makes these data unique with respect to pesticide (and IPM) policy is that we are directly measuring the "intent" of each insecticide input. That is, stakeholders are asked to identify the specific intent or intended target or targets of their management decisions and inputs. So in addition to rich quantitative data, we also have unique qualitative insights into the decision-making experience of the pest manager. These insights help guide our existing and new programs of IPM research, implementation and outreach. These data are useful in evaluating changes in grower practices and implementation of our IPM programs over time, and facilitating quick responses to the ever-changing needs of grower communities. Ongoing dialog with stakeholders through annual Crop Pest Losses workshops helps us quickly evaluate and respond to emerging pest management issues. For example, in 2011 we were able to quickly evaluate the impact of a new invasive insect pest, bagrada bug, on broccoli yields, quality and insecticide use. This information forms the basis of developing a response plan this new pest. Adopting IPM in Oregon Schools Two Oregon school districts are adopting IPM plans which include strong landscape management components. Pesticide use at all three schools was reduced. Outdoor harborage for indoor pests was reduced. A number of landscape IPM techniques were adopted by demonstration schools. For example, a high threshold of acceptance was created for playground weeds (kept low by foot traffic); vegetation is being planted around trees to outcompete weeds; and grounds staff are attempting to weed whack prior to seed production.

Impacts
This work group was established to encourage collaboration among universities, state agencies, federal agencies, industry, and advocacy groups working to encourage and enhance successful implementation of IPM in schools in the western region. To accomplish this, the group developed an inventory of programs and resources, worked to increase networking and communication and to improve access to and sharing of resources, and identified IPM implementation challenges and barriers. The group developed a school IPM (sIPM) assessment tool, completed a state-by-state inventory of sIPM resources among nine represented states, and succeeded in establishing productive collaborations among previously isolated programs. Original membership has continued to increase, and almost all the states in the western region are now represented. Conference calls, personal communications, and regular emails have facilitated discussions on future collaborative efforts and potential funding opportunities and fostered partnerships among emerging and ongoing sIPM efforts. Impacts and potential impacts include: Schools districts increasing their adoption of lower risk pesticides and precision application technology and equipment Schools providing/increasing staff training in implementing IPM tactics An increase in the number of schools, districts, and agencies that implement IPM plans A reduction in exposure of children and others to pests and unnecessary pesticides in schools, improving health and the learning environment Schools using cost- effective IPM practices Western IPM Center Work Group on Weather Systems Encompassing climatologists, entomologists, meteorologists, plant pathologists, and economists, this group's purpose was to further science-based principles and procedures for the acquisition, utilization, analysis, and distribution of weather and climate data for IPM management decisions. Collaborators also aimed to increase user confidence and utilization of weather data and pest, disease, and crop phenology models to enhance IPM management decisions in crop, rangeland, forest, horticultural, and urban environments. Collaborative research has resulted in the implementation of interpolated weather forecasts, including a "virtual weather station" system that uses interpolated data. Improved weather analysis and forecast models resulting from work group activities were used to develop fire weather forecasts in 2008. Many of the activities of the workgroup have culminated in the improvement of delivery of weather information at two Web portals, http://uspest.org/wea/ and http://weather.wsu.edu/. The latter provides data and analyses for the National Plant Diagnostic Network and presents data from more than 13,000 weather stations across the United States in a publically-accessible form. The work group is recognized as a leader in interpolation and delivery of weather, forecast, and pest model data; has set new standards and guidelines for weather-driven IPM; and has developed new methods for estimating parameters needed for pest models.

Impacts
Biodiversity Working for Farmers Tour: A tour conducted on three ecologically-rich farms in Oregon's Willamette Valley brought regional policy makers, conservationists, and industry personnel together with farmers and researchers to highlight the importance of agricultural biodiversity. Tour leaders led discussions on impacts of on-farm biodiversity, which include increased native pollinator populations, biological pest management, farm resiliency to environmental degradation, and regional contributions to local agricultural sustainability. Participants agreed on the need for increased communication to identify new policy opportunities to support conservation and promotion of on-farm biodiversity and to fund the participatory research and technological development that supports its implementation on a regional level. Shortly after this event, the tour was mentioned and had an important impact in Congressional testimony on pending food safety legislation. School Integrated Pest Management-A Change Agent Practicum: Through classroom instruction and on-site inspection and evaluation of a school facility, the 2-day practicum, held in Denver, Colorado, informed state and tribal officials (community "change agents") about pest management strategies in schools. Participants gained knowledge to support and promote implementation of IPM in their own state or tribe and to facilitate partnering with in-state and regional IPM experts. Seventy percent of the practicum's participants indicated they would change their current practices as a result of attending the event, and 100% said they would like to attend more advanced training on school IPM. National IPM Evaluation Group (NIPMEG) Subcommittee: NIPMEG's National IPM Evaluation Subcommittee has developed a Web site that is home to 16 IPM Logic Models. These models were developed by the subcommittee and peer reviewed by many IPM Coordinators, researchers, and other specialists. The models are an IPM planning and evaluation tool, using as examples the objectives stated in the National Roadmap for IPM. This is the culmination of a huge effort involving participation by Regional EPA Strategic Agricultural Initiative Programs, USEPA, Regional IPM Centers, USDA-NIFA, USDA National Sustainable Agriculture research and Education Program, and American Farmland Trust. The logic models are referenced by USDA in many of their competitive grant Requests for Applications. There have been three video conferencing workshops to assist people in the use of logic models and how to utilize the information found on the Web site. The models can be found at http://www.ipm.gov.

Progress 09/15/08 to 09/14/09

Outputs
OUTPUTS: Six western states were funded to participate in the Information Networks program, providing responses to USDA and USEPA on pest management and pesticide use questions. Personnel from these networks collaborate with a diverse group of stakeholders, including extension IPM coordinators. They identify critical issues in their states and the region. They aid in identifying appropriate individuals to whom IPM tactics use surveys, crop profiles, and Pest Management Strategic Plans should be addressed. Each participating state is required to maintain a web site with links to local pest management programs, materials and state programs. All states funded may be accessed through the WIPMC website: http://www.wripmc.org/ Eight different Work Groups were funded. These issue based work groups addressed a broad array of agricultural, urban and natural systems issues for one to two years. Six research and/or extension grants were issued. These projects covered a number of needs identified by western stakeholders. Four Special Projects were funded to address new, emerging or emergency issues. These brought experts together to develop plans for solving the problems. Two Pest Management Strategic Plans were supported by the WIPMC.

Impacts
An IPM practicum to inform state and tribal officials (community change agents) about pest management strategies in schools was held in Denver, CO. The event provided the knowledge to support and promote the implementation of IPM in states or tribes, and facilitated partnering with in-state and regional IPM experts. The Orchard Spray Application Technology Workgroup held a regional meeting in Portland, OR on January 13, 20 that drew 20 individuals from university faculty, USDA research, cooperative extension and industry. Important relationships were developed as a result of this meeting. A tower sprayer manufactured by Slimline Manufacturing of Penticton, BC, Canada has been leased by the Univeristy of California for one year. Slimline's owner gave a presentation at the January 13, 2009 meeting. The tower sprayer leased by UC has been demonstrated at two growers meetings in California in 2009 and will be part of research and demonstration projects until spring, 2010. One indirect outcome was the successful SCRI planning grant proposal ($50,000) titled "Development Of A Smart Targeted Spray Application Technology Roadmap For Specialty Crops". The January 13, 2009 meeting funded by the WIPM WG grant faciliated the involvement of California researchers, extension personnel, and stakeholders in the SCRI project. The meeting also facilitated the involvement in the SCRI planning grant of USDA ARS researchers from the USDA Spray Appliation lab in Wooster, Ohio. Since 1998, specialists at several Universities across the High Plains have cooperated in the production and dissemination of research-based pest management information through the High Plains IPM Guide. Despite its success, a major limitation of the Guide is the lack of weed management recommendations. In this project we are 1) coordinating a regional effort of producing and web-publishing weed biology, ecology, impact, and integrated management information on the High Plains IPM website and 2) disseminating the online Guide across a wide audience. A total of 22 authors from several states including Montana, Colorado, Nebraska, South Dakota, Wyoming, Oregon, and California developed 99 fact sheets with information on the biology, ecology, and management of weeds. Using a wiki format, these fact sheets were uploaded into the Bugwood HPIPM web site http://wiki.bugwood.org/Main_Page). We have conducted one Adobe Connect Pro session to train authors to update and modify the fact sheets.

Impacts
Crop Pest Losses and Impact Assessment Work Group coordinated with colleagues in the Texas Cooperative Extension system to organize a Cotton Insect Losses workshop in Lubbock, Texas, attended by 15 local stakeholders. There is interest in initiating cotton losses data collection in West Texas as part of a USDA RAMP grant on areawide management of Lygus, a polyphagous insect pest of many western crops. These data will help monitor changes in pest management practices and their impact over the four year project term. The Workgroup also updated the Cotton Insect Losses website which now features detailed Cotton Insect Losses data and analysis from 1979 through 2006 http://ag.arizona.edu/crops/cotton/insects/cil/cil.html). In 2008, the Work Group created a new home on the Arizona Crop Information Site for data and information related to Vegetable / Melon pest losses. This site provides easy access to stakeholders to the pest losses survey form, presentations, data and publications. These data and this Work Group serve to address any Federal, regional, state, and local requests for information on the impact of insects or insecticides on our key crops. As coordinator of the Arid Southwest IPM Network (another Western IPM Center - funded project), Al Fournier uses these data to respond to Federal pesticide information requests for the crops involved. Dr. Fournier had numerous informal requests for information in 2007 and 2008. Responses are posted on the Arid Southwest IPM Network website at http://ag.arizona.edu/apmc/Arid_SWPMC_Info_Requests.html. The Western Region School IPM Implementation and Assessment Work Group has built a foundation of collaboration and have documented a thorough inventory of existing resources and programs. We seek continued funding of this work groups activities, to further address the goal of the IPM Roadmap with respect to school IPM. Western IPM Center Work Group on Weather Systems conducted collaborative research that was a direct result of work group meetings that has resulted in the implementation of interpolated weather forecasts (e.g. http://pnwpest.org/cgi-bin/risk_model/risk_models), including an initial prototype "virtual weather station" (VWS) system which uses interpolated data. The VWS system, with resolution of 2km, was developed by Fox Weather, LLC and IPPC and is being ground-truthed. Improvements to Fox Weather weather analysis and forecast models as a result of workgroup activities now allow direct down-scaling of coastal effects to 800m resolution. The improved models are being delivered operationally in California, and were used to develop fire weather forecasts in 2008. A PRISM-based climate informed forecast system with a resolution of 800m has been developed and is being evaluated on an experimental basis. Uncertainty analyses are underway with the various weather analysis and forecasting systems. The use of PRISM climatological aided interpolation was demonstrated to reduce errors compared to temporal interpolation of missing data. Threshold-based pest models appear to be more susceptible to errors in interpolation of weather data than simulation type models.
