Bristlecone pine has weathered many climate changes. They’ve been getting punched in the face their entire species history and even, in some ways, thrive in the face of adversity. But whether they can make those adjustments in their range fast enough to keep up with climate change, that’s the question.
Access data review.
The purpose of the Data Product Review website is to provide a place where people can work through a review process of various LANDFIRE data products and a method for submitting feedback and suggestions on a number of LANDFIRE data products in a guidebook structure. The site is based on a content management platform with structured content for a dynamic web experience. The feedback and suggestions will be reviewed both within and external to LANDFIRE and potentially improve future mapping updates and remaps.

The Forest Health in Oregon: State of the State 2020 conference was February 26-27 at the LaSells Stewart Center on the campus of Oregon State University in Corvallis, OR. Geared to foresters, forest managers, woodland owners, students, and others with an interest in forest health, the conference provided a blend of current information and practical applications on how to manage a healthy forest.
Access data.
The dataset provides an estimate of 2018 herbaceous annual percent cover predicted on May 1st with an emphasis on annual grasses. The pixel values range from 0 to 100 with an overall mean value of 8.32 and a standard deviation of +/-11.93. The model’s test mean error rate (n = 1670), based on nine different randomizations, equals 4.9% with a standard deviation of +/- 0.15. This dataset was generated by integrating ground-truth measurements of annual herbaceous percent cover with 250-m spatial resolution eMODIS NDVI satellite derived data and geophysical variables into regression-tree software. The geographic coverage includes the Great Basin, the Snake River Plain, the state of Wyoming, and contiguous areas.

Presenter: Sarah McCaffrey
Description: Fire management in the United States is currently facing numerous challenges. While many of these challenges involve questions about how to increase pace and scale of fuels treatments and adapt to longer, sometimes year-round, fire seasons and more frequent extreme fires, there is also a need to adapt wildfire communication efforts to changing fire management needs and practices. This presentation will discuss insights from two decades of fire social science research about a range of topics to consider in improving wildfire communication including issues with conflation of language (prevention is not mitigation), when more rather than less complex explanations may be merited, and the need to account for how fire fits in everyday lives. The presentation will draw from general Communication, Natural Hazards, and Risk Communication theory, as well as specific fire social science research findings, about topics and approaches that are more or less likely to resonate with the public.

This study examines the drought fire relationship, specifically the correlations between water balance deficit and annual area burned, across the full gradient of deficit in the western USA, from temperate rainforest to desert. In the middle of this gradient, conditional on vegetation (fuels), correlations are strong, but outside this range the equivalence hotter and drier equals more fire either breaks down or is contingent on other factors such as previous year climate. This suggests that the regional drought fire dynamic will not be stationary in future climate, nor will other more complex contingencies associated with the variation in fire extent. Predictions of future wildfire area therefore need to consider not only vegetation changes, as some dynamic vegetation models now do, but also potential changes in the drought fire dynamic that will ensue in a warming climate.

This report evaluated the nesting and brood-rearing microhabitat factors that influence selection and survival patterns in the Great Basin using a large dataset of microhabitat characteristics from study areas spanning northern Nevada and a portion of northeastern California from 2009 to 2016. The spatial and temporal coverage of the dataset provided a powerful opportunity to evaluate microhabitat factors important to sage-grouse reproduction, while also considering habitat variation associated with different climatic conditions and areas affected by wildfire. The summary statistics for numerous microhabitat factors, and the strength of their association with sage-grouse habitat selection and survival, are provided in this report to support decisions by land managers, policy-makers, and others with the best-available science in a timely manner.

This synthesis reviews current knowledge of pinyon and juniper ecosystems, in both persistent and newly expanded woodlands, for managers, researchers, and the interested public. We draw from a large volume of research papers to centralize information on these semiarid woodlands. The first section includes a general description of both the Great Basin and northern Colorado Plateau. The ecology section covers woodland and species life histories, biology, and ecology and includes a detailed discussion of climate and the potential consequences of climate change specific to the Great Basin and Colorado Plateau. The history section discusses 20,000 years of woodland dynamics and geographic differences among woodland disturbance regimes and resilience. The ecohydrology section discusses hydrologic processes in woodlands that influence soil conservation and loss; water capture, storage, and release; and the effect that woodland structure and composition have on these processes. The final section, restoration and management, covers the history of woodland management, the different methods used, the advantages and disadvantages of different vegetation treatments, and posttreatment vegetation responses. We also discuss successes and failures and key components that determine project outcomes important for consideration when restoring ecosystem function, integrity, and resilience.
