View brief.
Pinyon jays present both a conservation challenge and a paradox. While the species has declined, its preferred habitat (pinyon-juniper woodlands) has expanded, and in some areas to a large extent. It seems that population declines are not a function of reductions in habitat amount, but are related to changes in habitat quality. Up to now research on the species has been paltry,
and so details about the trend have only recently begun to surface.
Description: Solving complex environmental problems requires extensive discussions and studies conducted by researchers from diverse disciplines including the natural and social sciences. Solutions to these environmental challenges usually depend on conceptual models of how these systems are linked and the essential processes within them, also known as coupled-human natural systems or socio-ecological systems. This webinar will provide insights on how collaborations can be most effective between natural and social scientists, providing examples from the speaker’s past and current research projects.
Presenter: Melissa M. Baustian, Ph.D. is a Coastal Ecologist with The Water Institute of the Gulf. She has more than 15 years of experience in researching the ecological responses of aquatic ecosystems to nutrient enrichment, eutrophication and hypoxia.

In the op-ed piece, Two Wildfires Everyone Should be Talking About, Wally Covingtion director of the Ecological Restoration Institute and professor of forest ecology at Northern Arizona University, suggests that by acting quickly and at larger scales, forest health can be restored and resiliency be built so that forests are better prepared for whatever changes may occur in the future.

High severity wildfires led to the greatest decrease in cover for all plant functional types, while low severity wildfires caused the least decrease in the functional type cover in most cases, though some variations existed. Furthermore, the impacts of wildfires on vegetation cover were greater in woody (SHR and TREE) types than in herbaceous (AFG and PFG) types. Significant negative correlation existed between percent changes in AFG and PFG cover and SPEI indicating higher prefire soil moisture conditions likely increased fine fuel loads and led to a larger decrease in AFG and PFG cover following wildfires. Significant positive correlation existed between percent changes in SHR and TREE cover and SPEI indicating drier prefire conditions resulted in larger decreases in SHR and TREE cover following wildfires.

Climate change is increasing the frequency, severity, and extent of area burned by wildfires in the U.S., putting more people at risk of exposure to fire itself and to smoke, which can travel thousands of miles and affect the health of millions of people. A.R. “Ravi” Ravishankara (Colorado State University) will moderate a conversation between Sarah Coefield (Missoula City-County Health Department) and Erica Fischer (Oregon State University) about how planners and decision makers are coping with these challenges and working to protect the built environment and human health.

This guide features 40 bird species that utilize sagebrush habitats and includes tips on species identification, biology, and conservation status. Because not all of these species require similar habitat types and not all sagebrush is managed for the same goals, this guide discusses how avian needs can be incorporated into land management plans.

Join us in the heart of New Mexico for the 75th Annual SRM Meeting. The beautiful high desert rangelands, diverse cultures, authentic art, and painted skies of Albuquerque will make for a great meeting.
Webinar recording and additional Q and A.
Federal and state agencies across Utah and the Great Basin have been actively treating pinyon and juniper woodlands to improve wildlife habitat, reduce fuel loads, and achieve watershed objectives. Increasingly these activities have been questioned by stakeholder groups and citizens who are concerned about the unintended consequences of such treatments. This webinar addresses some of the recent criticisms of pinyon-juniper treatment, sharing results of research on woody vegetation removal as well as identifying questions that still need to be answered through research and monitoring.

New technologies may enhance management by enabling quantitative testing of assumptions of vegetation response to climate and management. State-and-transition simulation models can keep track of interactions that are too complicated for us to comprehend using only conceptual models. This tool takes conceptual state-and-transition models to the next level, fostering greater communication and dialogue with stakeholders. Based on the models and climate data used here, increased drought may enhance transitions between vegetative states. It is important to be as explicit and quantitative as possible as to how you expect vegetation states or ecosystem processes to transition between one another.
Access report.
Spot fires caused by wind-blown burning embers are a significant mechanism of fire spread in the wildland and Wildland-Urban Interface (WUI). Fire spread and structure ignition by embers can be characterized by three major processes or mechanisms: ember production, ember transport, and ember ignition of fuel. This study investigates ember production from selected wildland and structural fuels under a range of environmental conditions through full-scale, intermediate-scale, and small-scale laboratory experiments.
