There is increasing interest in thinning of sprouting species to accelerate the formation of tree characteristics important to indigenous cultural practices and wildlife such as large-diameter stems, large branches, broad crowns, and acorn production. We compared responses to three thinning treatments applied to black oak (Quercus kelloggii) resprouting after high-severity wildfire throughout northern California, USA. Basal area increment of the dominant stem was greatest...AuthorsMartin Ritchie, John-Pascal Berrill, Ethan Hammett, Jonathan W. LongKeywordsSourceJournal of Forestry. 122(1): 70-78Year2023
- Given the high costs of constructing, maintaining, monitoring, and sampling paired watersheds, it is prudent to ask “Are paired watershed studies still worth the effort?” We present a compilation of 90 North American paired watershed studies and use examples from the Caspar Creek Experimental Watersheds to contend that paired watershed studies are still worth the effort and will continue to remain relevant in an era of big data and short funding cycles. We offer three reasons to justify this assertion. First, paired watersheds allow for watershed-scale experiments that have produced...AuthorsPaul W. Richardson, Peter H. Cafferata, Salli F.

- The 3rd North American Mass Timber Research Needs Assessment Workshop sponsored by the US Forest Service, Forest Products Laboratory was held September 20-22, 2022. The purpose of the workshop was to convene experts on mass timber and cross laminated timber to develop a prioritized list of research needs for the North American mass timber industry. Invited workshop participants included design professionals, academics, industry leaders, and government employees. The workshop built upon prior mass timber research needs workshops that were conducted in 2015 and 2018.AuthorsSamuel L. Zelinka, Richard Bergman, Marco Lo Ricco, William A.

- Management of forest lands considering multi-functional approaches is the basis to sustain or enhance the provision of specific benefits, while minimizing negative impacts to the environment. Defining a desired management itinerary to a forest depends on a variety of factors, including the forest type, its ecological characteristics, and the social and economic needs of local communities. A strategic assessment of the forest use suitability (FUS) (namely productive, protective, conservation-oriented, social and multi-functional) at regional level, based on the provision of forest ecosystem...AuthorsGoran Krsnik, Keith M.

- Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action1,2. Ongoing developments in taxonomy, threatening processes and research further underscore the need for reassessment3,4. Here we report the findings of the second Global Amphibian Assessment, evaluating 8,011 species for the International Union for Conservation of Nature Red List of Threatened Species. We find that amphibians are the most threatened vertebrate class (40.7% of species are globally threatened). The updated Red List Index shows that the status of amphibians...AuthorsBurhan Tjaturadi, Carlos C. Martínez Rivera, Carlos R. Vásquez Almazán, Celsa Señaris, S. R.

- Widespread declines in breeding bird populations have been documented across North America since the 1970s, and concerns about loss of avian biodiversity are growing. Species with narrow habitat preferences are of particular conservation concern. Connecticut Warblers (Oporornis agilis) breed in forests in central Canada and around the western Great Lakes; throughout much of its breeding range, this species is associated with lowland black spruce (Picea mariana) and tamarack (Larix laricina) forests. Population trends of the Connecticut Warbler indicate it is one of the most rapidly...AuthorsAlexis Grinde, Stephen Kolbe, Kara Snow, Brett Howland, Gerald Niemi, Robert A.

- Management and conservation efforts that support the recovery and protection of large rivers are daunting, reflecting the complexity of the challenge and extent of effort (in terms of policy, economic investment, and spatial extent) needed to afford measurable change. These large systems have generally experienced intensive development and regulation, compromising their capacity to respond to disturbances such as climate change or wildfire. Functionally, large river and basin management require insights gained from social, ecological, geophysical, and hydrological sciences. This multidiscip...AuthorsRebecca Flitcroft, Luke Whitman, James White, Rose Wallick, Laurel Stratton Garvin, Cassandra Smith, Robert Plotnikoff, Michael Mulvey, Tobias Kock, Krista Jones, Peter Gruendike, Carolyn Gombert, Guillermo Giannico, Andrew Dutterer, Daniel Brown, Hannah Barrett, Brian Bangs, Robert M.

- This study conducted a cradle-to-grave life-cycle assessment (LCA) of engineered wood flooring manufactured in the eastern United States. System boundaries in this study included the following information modules: raw material extraction (A1), raw material transportation (A2), product manufacturing (and packaging) (A3), product transportation (A4), installation (A5), product use (B1-B7), and end-of-life (C1-C4). Two disposal options were considered for flooring products at the end of useful life: landfilling and burning. The burning option captures heat, which displaces use of natural gas....AuthorsM.

- White-headed Woodpeckers (Dryobates albolarvatus) are strongly associated with late-successional dry forest types. Callback surveys along transects are typically used to understand their status and trends in response to forest management. However, this survey method has proven to be logistically challenging because of the number of spatial and temporal replicate surveys needed to accurately interpret surveys that yield no detections. Passive acoustic recording units (ARUs) effectively detect certain avian species and may offer a more efficient and effective survey method, but few studies...AuthorsMarie Gaylord, Adam Duarte, Brenda McComb, Jamie RatliffKeywordsSourceJournal of Field Ornithology. 94(4):1.Year2023
