- New approaches to managing climate change uncertainty rely on integrating innovative forest management practices with adaptive management techniques and robust decision-support strategies. Forest management alternatives for a changing climate can enhance ecosystem health and sustainability while ensuring the flow of ecosystem services, such as water, wildlife, biodiversity, recreation, and ecosystem resilience. Ideally, these methods will help reverse the decline in ecosystem function from associated ecological disturbances, such as drought, wildfire, insects, diseases, or invasive...AuthorsCarlos Rodriguez Franco, Deborah S.

- Soil physical and chemical properties play important roles in mass loss during soil-block tests but the relationship between soil properties and the decay caused by brown-rot and white-rot fungi remains unclear. The objective of this study was to investigate the soil effects on the decay resistance of pine (Pinus spp.) and poplar (Liriodendron tulipifera L.) blocks. The properties of soil from nine different sources (six from Idaho, one from Mississippi, one from Wisconsin, and one from Oregon) were characterized for soil texture, sieved bulk density, water-holding capacity, pH, organic...AuthorsChi-Jui (Barry) Kuo, Mark Kimsey, Deborah S.

- We (Jacobs et al. 2021) analyzed an extensive 21- year data set of Chinook Salmon Oncorhynchus tshawytscha redd locations to (1) explain covariation between redd occurrence and environmental variables in the Middle Fork Salmon River (MFSR) and (2) leverage these relationships to predict changes in Chinook Salmon spawning habitat distribution under future climate scenarios. We have since discovered a small but consequential error in the process we used for applying future climate scenarios to our redd occurrence model in pursuit of our second objective: to predict the response of Chinook...AuthorsGregory R.

- Climate change threatens biodiversity through global alteration of habitats, but efficient conservation responses are often hindered by imprecise downscaling of impacts. Besides thermal effects, warming also drives important ancillary environmental changes, such as when river hydrology evolves in response to climate forcing. Earlier snowmelt runoff and summer flow declines are broadly manifested in snowdependent regions and relevant to socioeconomically important cold-water fishes. Here, we mechanistically quantify how climate-induced summer flow declines during historical and future...AuthorsDaniele Tonina, James A. McKean, Daniel J. Isaak, Rohan M.

- Lewis flax (Linum lewisii) is widely distributed across western North America and is currently used in native ecosystem restoration. There is also growing interest in de novo domestication of Lewis flax as a perennial oilseed crop. To better understand this species and facilitate both restoration and domestication, we used common gardens to assess biogeographical variation in a variety of seed and growth traits from 37 flax accessions, consisting of 35 wild populations from the Intermountain West region, the pre-variety germplasm Maple Grove (L. lewisii) and the cultivar ‘Appar’ (L....AuthorsPeter Innes, Andre Gossweiler, Scott L.

- Fire regimes in North American forests are diverse and modern fire records are often too short to capture important patterns, trends, feedbacks, and drivers of variability. Tree-ring fire scars provide valuable perspectives on fire regimes, including centuries-long records of fire year, season, frequency, severity, and size. Here, we introduce the newly compiled North American tree-ring fire-scar network (NAFSN), which contains 2562 sites, > 37,000 fire-scarred trees, and covers large parts of North America. We investigate the NAFSN in terms of geography, sample depth, vegetation, topograph...AuthorsDavid W. Huffman, Jose Iniguez, Kurt F. Kipfmueller, Stanley G.

- The remote sensing of fire severity and burned area is fundamental in the evaluation of fire impacts. The current study aimed to: (i) compare Sentinel-2 (S2) spectral indices to predict field-observed fire severity in Durango, Mexico; (ii) evaluate the effect of the compositing period (1 or 3 months), techniques (average or minimum), and phenological correction (constant offset, c, against a novel relative phenological correction, rc) on fire severity mapping, and (iii) determine fire perimeter accuracy. The Relative Burn Ratio (RBR), using S2 bands 8a and 12, provided the best corresponden...AuthorsAdrian Israel Silva-Cardoza, Daniel Jose Vega-Nieva, Jaime Briseno-Reyes, Carlos Ivan Briones-Herrera, Pablito Marcelo Lopez-Serrano, Jose Javier Corral-Rivas, Sean A.

- Beginning in 1973, the National Silviculture Workshop (NSW) purposely brought together USDA Forest Service scientists from Research and Development and forest managers from the National Forest System to meet face-to-face to build a science and management partnership in silviculture. Recently, scientists from universities and other partners have joined this annual gathering. The 2022 NSW theme is “Foundational Concepts in Silviculture: Emphasis on Reforestation and Early Stand Improvement.” In 2022, the workshop is scheduled to take place in Kellogg, Idaho and is being jointly hosted by the...AuthorsTerrie B.

- Recent increases in area burned, combined with poor natural regeneration in some areas, have promoted concerns about widespread forest losses throughout the western U.S. Postfire reforestation is one strategy commonly employed by land managers and land owners to facilitate forest recovery, but the area in need of planting only becomes larger each year. The Southern Rockies Reforestation Tool (SRRT) is a simple web-mapping tool that was developed to help prioritize sites for postfire reforestation. This tool can be used to develop maps of fire severity and seedling suitability for ponderosa...AuthorsKyle Rodman, Paula J.

- We used historical and contemporary survey data to assess the dynamics in two old-growth forests at Savage Mountain, Maryland, versus secondary forests from the surrounding landscape of the northern Allegheny Mountain Plateau (AMP). This is the first published compilation of witness trees from western Maryland. The oldgrowth forests on Savage Mountain, Maryland, are presently dominated by mixed oak (Quercus spp. L.; 42%), red maple (Acer rubrum L.), and black birch (Betula lenta L.). Witness trees (1620-1825) from Savage Mountain were dominated by mixed oak (55%), hickory (Carya spp.;...AuthorsMarc D. Abrams, Brice Hanberry, Charles M.
