Nonindigenous forest insects and pathogens affect a range of ecosystems, industries, and property owners in the United States. Evaluating temporal patterns in the accumulation of these nonindigenous forest pests can inform regulatory and policy decisions. We compiled a comprehensive species list to assess the accumulation rates of nonindigenous forest insects and pathogens established in the Un...

Forest certification programs provide standards for multiple aspects of forest management, including the use of chemicals for mitigating competition and forest pests. The three most common programs in the United States—the American Tree Farm System, the Forest Stewardship Council, and the Sustainable Forestry Initiative—all address chemical use. To evaluate relative impacts under different cert...

Tree species distributions associated with rainfall are among the most prominent patterns in tropical forests. Understanding the mechanisms shaping these patterns is important to project impacts of global climate change on tree distributions and diversity in the tropics. Beside direct effects of water availability, additional factors co-varying with rainfall have been hypothesized to play an im...

reported that the decline in forest growth could lead to annual US timber market losses from $2.3 billion to $3.8 billion. [1] Governments and the private sector also spend substantial amounts on research and development of technologies to monitor, detect, and control invasive pests. Annual expenditures by the US federal government on all agricultural pests increased from $500 million in the mi...

We present and analyze a nonlinear dynamical system modelling forest-pests interactions and the way they are affected by acidic deposition. The model includes mechanisms of carbon and nitrogen exchange between soil and vegetation, biomass decomposition and microbial mineralization, and defoliation by pest grazers, which are partially controlled by avian or mammalian predators. Acidic deposition...

E ective forest management is crucial to maximising the economic bene ts obtained from forests. However, the arrival of novel pests and pathogens may have a negative e ect on timber values. We argue that management strategies should be calibrated to consider the e ect of disease and in this paper explore the optimal rotation length of a single rotation, even-aged, plantation forest under varyin...
