The economic and environmental threats posed by non-native forest insects are ever increasing with the continuing globalization of trade and travel; thus, the need for mitigation through effective biosecurity is greater than ever. However, despite decades of research and implementation of preborder, border, and postborder preventative measures, insect invasions continue to occur, with no evidence of saturation, and are even predicted to accelerate. In this article, we review biosecurity measures used to mitigate the arrival, establishment, spread, and impacts of non-native forest insects...

Vehicular emissions comprise a main source of air pollutants, especially particulate matter (PM), which contains toxic compounds. Brazil has been restricting vehicular emissions for more than 30 years to minimize the impacts of fleet vehicles, but despite the restrictive legislation, several Brazilian cities still suffer from the effects of atmospheric pollution. The adoption of nature-based solutions (NbS) is being hailed as a sound alternative for improving urban air quality. In this sense, trees are a true reflection of the NbS concept since they can directly decrease PM levels by...

Aims. Canadian goldenrod (Solidago canadensis) invasion is degrading the coastal shelterbelt forests of subtropical China, but few studies have quantified the role of this invader in structuring understory plant diversity and soil properties. Methods. Understory species richness, Margalef index, Pielow index, community stability index, soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP), C:N ratio, pH, bulk porosity (BP), and aeration porosity (AP) were assessed by deriving three categories of goldenrod invasion in coastal shelterbelt forests of Zhejiang, China, that is,...

Researchers have documented that vacant lot greening can reduce communitylevel crime and violence. Busy Streets Theory (BST) suggests that residents who are involved in the greening process can help to improve physical environments and build social connections that deter crime and violence. Yet few researchers have explored how community engagement in the greening process may affect crime and violence outcomes. We applied BST to test the effects of communityengaged vacant lot greening compared to vacant lots that received either professional mowing or no treatment, on the density of...

Context. Public-private partnerships are needed to conserve landscapes, waterscapes, and seascapes. Landscape conservation design (LCD) translates shared objectives into spatial priorities to guide conservation efforts and foster collaboration among partners at the landscape level. Objective. We examined LCD projects in the eastern United States to identify implementation and coordination challenges and propose solutions that facilitate integration across projects in instances when coordination and continuity of conservation efforts is paramount. Methods. We apply a scale dynamics approach...

Serious games are designed to achieve specific educational or other practical purposes beyond pure entertainment. These games take many different forms—from card decks to massive multiplayer online games—and have proliferated across diverse fields. This note introduces IMPACT: Forestry Edition, a serious board game designed to help forestry professionals and stakeholders think more broadly, critically, and creatively about the future of forestry. We describe the game and feedback from beta testing and discuss the advantages and potential drawbacks of gaming methods. A "print and play"...

The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), a wood-boring beetle native to Asia, is the most damaging invasive forest insect pest to have invaded North America (Herms and McCullough 2014). It was likely introduced in the mid-1990s (Siegert et al. 2014), but was not discovered until 2002 near Detroit, Michigan (Haack et al. 2002; Poland and McCullough 2006). In EAB’s native range in far eastern Russia, northern China, Japan, and Korea, it is generally only a pest of non-native ash or indigenous ash species (Fraxinus spp.) that are stressed by other...

Nonresponse in national forest inventories primarily occurs in forested areas due to accessibility issues or where hazardous conditions exist. As with all surveys, nonresponse has the potential to impart empirical bias into sample-based estimates and care should be taken to minimize any effects. A less-studied aspect is the effects of nonresponse when estimating change between two points in time. In this study, potential bias in change estimates was evaluated using imputed values for nonresponse inventory plots to compare differences between response and nonresponse means. Analysis of...

The United States of America has a remarkable forest resource—more than 765 million acres of planted and natural forest land and an additional 58 million acres of woodlands. These lands provide clean water, clean air, wildlife and fish habitat, recreational opportunities, and for nearly four centuries have been the foundation for economic development. This atlas introduces the reader to a trove of information also available online at the forest atlas website, https://forest-atlas.fs.usda.gov.Evolving from the first inventory of U.S. forests in the 1870s, the Forest Inventory and Analysis...

Este documento fue elaborado por el Instituto de Ciencias Climáticas Aplicadas del Norte en colaboración con el Centro Climático de Bosques del Norte del Departamento de Agricultura de los Estados Unidos de Norteamérica. La Guía rápida se desarrolló como punto de acceso para la planificación a la adaptación al cambio climático para profesionales de recursos naturales. Es paralela a una guía de adaptación desarrollada específicamente para fideicomisos de tierras en colaboración con “Land Trust Alliance”, Guía rápida de planificación a la adaptación para fideicomisos de tierras, pero se...
