Southwest Forest Management
Forests in the Southwest are ecologically important for their watershed, wildlife, and rangeland functions. Economically, forests are valued for the natural resource and recreational opportunities they provide. These functions and values are important to stakeholders who have for several centuries depended on natural resources for food, fiber, and shelter. In light of this multiple-use significance, forest resilience is of great interest to land managers charged with stewardship responsibilities. However, following a century of fuel buildup in the absence of frequent fire due to fire suppression, current fire regimes in many southwestern forest are characterized by low frequency, high-severity crown fires.
In light of the frequency, size, severity, and media coverage surrounding recent stand-replacement crown fires across the western United States, the pendulum of forest management has swung in a new direction. A new paradigm of restoration and fuel reduction management has arrived. The solution to reducing the risk of large-scale crown fires throughout the West is widely believed to lie in surface an aerial fuels reduction. Managers, an increasingly educated public, and students are interested the effects restoration and fuel reduction treatments have on fire severity, succession, hydrology, wildlife habitat, and even the local economy. Land managers are also interested and challenged in deciding how to allocate limited budget funds between post-fire rehabilitation and pre-fire restoration treatments. Increased knowledge, availability of information, and training opportunities to guide forest management decisions are desired and have been requested.

Wildlife Management in New Mexico
People encounter wildlife at home, work and while engaged in recreation. Wildlife may represent significant opportunities and challenges for people. New Mexico's farmers, ranchers and urban citizens need information detailing basic ecology, human health issues related to wildlife, animal biology and management, habitat management, wildlife damage management and wildlife enterprise development. Further information regarding basic ecology, management and human health issues regarding commonly encountered wildlife is needed by youth and adults. Educational programs needed for urban and rural residents often differ in the types of information people need regarding wildlife damage management, wildlife enterprises, and wildlife ecology and management. Objectives of this are:
- to provide wildlife damage management education and demonstration relevant to urban and rural environments,
- to provide education related to diversification or income through wildlife enterprises, and
- to provide general wildlife ecology and management education for youth and adults in rural and urban settings.

Title: Extension Brush & Weed Specialist
Office Phone: 575-646-4948
I started in mid-January 2016 as the Ext Rangeland Brush & Weed Specialist for NM. My experience with invasive plants began on our farm in western Idaho where we raised beef and dairy cows. Later, college and work experience would continue my relationship with invasive plants. I studied rangeland related coursework at Treasure Valley Community College, Eastern Oregon University, Oregon State University, and Brigham Young University. My research work during graduate school focused on brush and weed ecology and management. I had the opportunity to work with several plant species especially juniper, pinon, cheatgrass, medusahead, bluebunch wheatgrass, and squirreltail. I practiced my training as a licensed professional pesticide applicator for Washington County in Idaho where thistles were a common target among other noxious weeds.
My natural resource work continued as a rangeland management specialist for the Natural Resources Conservation Service in southern Idaho. I served the public by working with private landowners to develop resource management plans and apply best management practices to conserve natural resources. Some of the improvement projects I worked on included revegetation, livestock water development, fencing, confined animal feeding operations, rotational grazing plans, irrigation systems, wetland restoration, wildlife habitat, and biological weed control. I listened to local landowner concerns and engaged the public at soil and water conservation district meetings and cattleman association meetings.
Most recently, I worked as an NMSU Assistant Research Professor (postdoctoral) under direction of the USDA Agricultural Research Service, Jornada Experimental Range. I led development of the Chihuahuan Desert Rapid Ecoregional Assessment funded by the Bureau of Land Management. In these landscape assessments, we synthesized current scientific understanding of the ecological structure and function of the ecoregion and the effect of ecological drivers (e.g., invasive plants, climate change, grazing, human use, urban and industrial growth, fire, and restoration practices) on the condition of several ecosystems and wildlife species. We used conceptual models, structured decision making, geospatial layers, and narratives to discuss the ecology and management of the ecoregion and address land management questions.
