- Deforestation and natural resource extraction are well-known threats to biodiversity conservation, environmental justice, livelihoods, ecosystem services and can even result in crimes to, and harassment of, environmental defenders. Such punitive actions against environmental defenders can influence both economic development and forest conservation efforts. Yet, little is known about this nexus and the complex relationships between environmental impacts, such as deforestation, and environmental crimes across space and time in many regions such as Latin America. We explored these complex...AuthorsNicola Clerici, Christina Staudhammer, Francisco J. EscobedoKeywordsSourceTrees, Forests and People. 17(6630): 100610.Year2024
- Herbivorous insects alter biogeochemical cycling within forests, but the magnitude of these impacts, their global variation, and drivers of this variation remain poorly understood. To address this knowledge gap and help improve biogeochemical models, we established a global network of 74 plots within 40 mature, undisturbed broadleaved forests. We analyzed freshly senesced and green leaves for carbon, nitrogen, phosphorus and silica concentrations, foliar production and herbivory, and stand-level nutrient fluxes. We show more nutrient release by insect herbivores at non-outbreak levels in...AuthorsBernice C. Hwang, Christian P. Giardina, Stephen Adu-Bredu, M. Noelia Barrios-Garcia, Julio C.

- The US faces multiple challenges in facilitating the safe, effective, and proactive use of fire as a landscape management tool. This intentional fire use exposes deeply ingrained communication challenges and distinct but overlapping strategies of prescribed fire, cultural burning, and managed wildfire. We argue for a new conceptual model that is organized around ecological conditions, capacity to act, and motivation to use fire and can integrate and expand intentional fire use as a tool. This result emerges from more considered collaboration and communication of values and needs to address...AuthorsAaron Russell, Nina Fontana, Tyler Hoecker, Alyssa Kamanu, Reetam Majumder, Jilmarie Stephens, Adam M.

- Purpose of Review Forests play an essential role in conserving pollinating insects and supporting pollination services in mixed-use landscapes and are particularly important to species that require resources restricted to forests. However, some forests provide higher quality habitat for these organisms than others. The primary objectives of this article are to 1) review how pollinator communities are influenced by changes in forest structure, composition, and age, 2) explore how these patterns differ between conifer and broadleaf forests, and 3) provide recommendations for managers...AuthorsMichael Ulyshen, Kimberly Ballare, Christopher J.

- Mangroves’ ability to store carbon (C) has long been recognized, but little is known about whether planted mangroves can store C as efficiently as naturally established (i.e., intact) stands and in which time frame. Through Bayesian logistic models compiled from 40 years of data and built from 684 planted mangrove stands worldwide, we found that biomass C stock culminated at 71 to 73% to that of intact stands ~20 years after planting. Furthermore, prioritizing mixed-species planting including Rhizophoraspp. would maximize C accumulation within the biomass compared to monospecific planting....AuthorsCarine F. Bourgeois, Richard A.

- Strawberry guava (waiawī, Psidium cattleyanumSabine, Myrtaceae) is a small tree invasive on oceanic islands where it may alter forest ecosystem processes and community structure. To better understand the dynamics of its invasion in Hawaiian rainforests in anticipation of the release of a biocontrol agent, we measured growth and abundance of vertical stems ≥0.5 cm DBH for 16 years (2005–2020) in Metrosideros-Cibotiumrainforest on windward Hawai'i Island. Specifically, we compared the growth and abundance of both shoots (originating from seed or from the root mat) and sprouts (originating...AuthorsJulie S. Denslow, M.

- Reliable estimates of population trends are important for prioritizing and implementing wildlife management actions. Abundance estimates are the most informative metric of population status but are difficult and costly to achieve for rare or elusive species. For bat species that are highly mobile and nocturnal, abundance estimates are usually only possible at their roosts. Although they are relatively easy to census in individual roosts, it is often unclear whether observed trends are representative of broader populations trends. Dual-frame sampling is useful for monitoring wildlife...AuthorsTed Weller, Katrina J. Smith, Shawn C. Thomas, James A. BaldwinKeywordsSourceThe Journal of Wildlife Management. 88(4): 1294.Year2024
- The California spotted owl (Strix occidentalis occidentalis) is an older-forest associated species that resides at the center of forest management planning in the Sierra Nevada and Southern California, USA, which are experiencing increasingly large and severe wildfires and drought-related tree mortality. We leveraged advances in passive acoustic survey technologies to develop an acoustically assisted survey design that could increase the efficiency and effectiveness of project-level surveys for spotted owls, allowing surveys to be completed in a single year instead of in multiple years. We...AuthorsH. Anu Kramer, Kevin G. Kelly, Sheila A. Whitmore, William J. Berigan, Dana S. Reid, Connor M. Wood, Holger Klinck, Stefan Kahl, Patricia N. Manley, Sarah Sawyer, M. Zachariah.

- 1. There are concerns over the effects of increasingly large and high-severity fires that burn outside the local natural range of variation on ecosystem services and biodiversity. 2. Pollinators provide important ecosystem services in the dry forests of the western United States where they depend on open habitat created or maintained by frequent, low- to moderate-severity fire. 3. We investigated the impact of burn severity on pollinator diversity in upland forest and meadow habitat at local (i.e., at the plot scale) and regional (burn severity class) spatial scales in the Sierra Nevada of...AuthorsGina L.

- As wildfires worsen across the globe, there is increased attention on the inequitable distribution of the risks to people. Pre-existing risks and vulnerabilities compound the risk to many populations. Those who bear the worst of these risks are usually underserved and ethnic/racial minority communities.AuthorsAlyssa ThomasSourceOne Earth. 7(6): 956-958Year2024
