Assessing New England Family Forest Owners\u27 Invasive Insect Awareness

Family forest owners in the United States have underscored the need for forest insect pest (FIP) information, and numerous Extension programs have been developed to meet pest information needs. We developed the Pest Awareness Index to illustrate the heterogeneity of familiarity, knowledge, and experience regarding three FIPs (hemlock woolly adelgid, emerald ash borer, Asian long-horned beetle) in four New England states. Using mail survey data of family forest owners, we calculated an index from three components and provided comparisons based on region and actual insect presence. The differences in the index across these domains have implications for measurement and delivery of Extension programs

Science and society: The Role of Long-term Studies in Environmental Stewardship

Long-term research should play a crucial role in addressing grand challenges in environmental stewardship. We examine the efforts of five Long Term Ecological Research Network sites to enhance policy, management, and conservation decisions for forest ecosystems. In these case studies, we explore the approaches used to inform policy on atmospheric deposition, public land management, land conservation, and urban forestry, including decisionmaker engagement and integration of local knowledge, application of models to analyze the potential consequences of policy and management decisions, and adaptive management to generate new knowledge and incorporate it into decisionmaking. Efforts to enhance the role of long-term research in informing major environmental challenges would benefit from the development of metrics to evaluate impact; stronger partnerships among research sites, professional societies, decisionmakers, and journalists; and greater investment in efforts to develop, test, and expand practice-based experiments at the interface of science and society

How Family Forest Owners Consider Timber Harvesting, Land Sale, and Conservation Easement Decisions: Insights from Massachusetts, USA

Ten million family forest owners own 35 percent of US forestland. Although one owner\u27s action may be insignificant, many owners\u27 decisions across the landscape and over time can together affect the forest ecosystem. By analyzing survey data from Massachusetts, this paper examines the thought processes of family forest owners when considering timber harvesting, land sale, and conservation easement decisions, all having great potential to shape the future of individual properties and forest landscape. Some factors (e.g., attitudes towards forestland and desire for and experience of cooperation) were important for engaged and unengaged owners, some factors (e.g., attained education level, age, and absenteeism) were irrelevant, and some factors (e.g., acreage and information sources) had mixed effects depending on the decision and landowner engagement level. The results suggest the need to avoid any one-size-fits-all approach, differentiate landowners based on their engagement level, and tailor outreach efforts to address the interests and concerns of particular audiences

Urban forestry priorities of Massachusetts (USA) tree wardens

As part of a survey we sent to tree wardens (individuals responsible for public trees) in communities in Massachusetts, USA, we examined which urban forest management tools and activities were most important to tree wardens themselves. Tree wardens generally agreed that inter-departmental communication and Chapter 87 (a state law promulgating the powers of a tree warden) were more important than having a qualified tree warden, an advocacy/advisory group, or a management plan (measures recognized by the USDA Forest Service in the Community Accomplishment Reporting System). Nearly all tree wardens prioritized removing dead and hazard trees. We discuss management implications of our results, paying particular attention to the importance of state laws in supporting urban forest management

The influence of land use and climate change on forest biomass and composition in Massachusetts, USA

Land use and climate change have complex and interacting effects on naturally dynamic forest landscapes. To anticipate and adapt to these changes, it is necessary to understand their individual and aggregate impacts on forest growth and composition. We conducted a simulation experiment to evaluate regional forest change in Massachusetts, USA over the next 50 years (2010–2060). Our objective was to estimate, assuming a linear continuation of recent trends, the relative and interactive influence of continued growth and succession, climate change, forest conversion to developed uses, and timber harvest on live aboveground biomass (AGB) and tree species composition. We examined 20 years of land use records in relation to social and biophysical explanatory variables and used regression trees to create ‘‘probability-of-conversion’’ and ‘‘probability-of-harvest’’ zones. We incorporated this information into a spatially interactive forest landscape simulator to examine forest dynamics as they were affected by land use and climate change. We conducted simulations in a fullfactorial design and found that continued forest growth and succession had the largest effect on AGB, increasing stores from 181.83 Tg to 309.56 Tg over 50 years. The increase varied from 49% to 112% depending on the ecoregion within the state. Compared to simulations with no climate or land use, forest conversion reduced gains in AGB by 23.18 Tg (or 18%) over 50 years. Timber harvests reduced gains in AGB by 5.23 Tg (4%). Climate change (temperature and precipitation) increased gains in AGB by 17.3 Tg (13.5%). Pinus strobus and Acer rubrum were ranked first and second, respectively, in terms of total AGB throughout all simulations. Climate change reinforced the dominance of those two species. Timber harvest reduced Quercus rubra from 10.8% to 9.4% of total AGB, but otherwise had little effect on composition. Forest conversion was generally indiscriminate in terms of species removal. Under the naı¨ve assumption that future land use patterns will resemble the recent past, we conclude that continued forest growth and recovery will be the dominant mechanism driving forest dynamics over the next 50 years, and that while climate change may enhance growth rates, this will be more than offset by land use, primarily forest conversion to developed uses.Organismic and Evolutionary Biolog

Measuring urban forestry performance and demographic associations in Massachusetts, USA

The United States Forest Service measures successful management of the urban forest by the number of communities that have achieved some or all of four parameters described by the Community Accomplishment Reporting System. The four parameters address whether a community has: (1) a management plan, (2) professional staff, (3) urban forestry ordinances/policies, and (4) an advocacy/advisory organization. We surveyed tree wardens in the Massachusetts communities to determine how many communities met each parameter, as well as other indicators of urban forest management. Nearly all responding communities met 1 performance parameter, but only 15% met all 4 parameters. Communities with greater population were more successful in achieving the parameters than those with smaller population
