They appear m as if perfectly cut with pruning The Davey Tree The Davey shears. Could it be squirrels? We have had quite a few nesting in that tree. Though otherwise healthy, the tree concerns me as it is very large and spreads over parts of my house. We lost the central limb in Tropical Storm Irene. I have read that silver maples are weak and untrustworthy, but it seems healthy other than the bizarre issue detailed above. A: Most likely the clusters of twigs with leaves are cut by squirrels seek- ing nesting material or a sugar snack. Silver maples shed small branches year-round. The weak-wooded accusa- tions about silver maple are generally because of its propensity for included bark — the bark embedded at joints between branches. This creates weak branch/trunk crotches and leads to failure of large stems during wind and snow storms. Wood-rotting fungi began decaying the trunk after the Black walnut central limb was lost. The tree should be checked by a qualified arborist. nnie a Weighted Walnuts a C ri Q: We have many large, black walnut trees on our property. e Since about mid-summer, they have dropped branches almost weekly. The branches range in length from 10 to 30 feet. The trees seem very heavy with walnuts — more so than in years past. Also, we had a severe drought last year. Are the trees dying? A: It’s probably a combination of the weight of heavy fruit this year and the after-effects of severe drought, which can last four to seven years. Trees will shed foliage to conserve moisture as drought intensifies, but it may take a few years for the branch to fall. Soil-apply a slow-release, low-burn fertilizer and Silver maple water to prevent drought stress. 4 | Winter 2014 AMerICAnforests.org Challenged ölk w er G Cherry i D ü r Q: I live in north Carolina.

  • Urban Forest Assessments Resource Guide
    Trees in cities, a main component of a city’s urban forest, contribute significantly to human health and environmental quality. Urban forest ecosystem assessments are a key tool to help quantify the benefits that trees and urban forests provide, advancing our understanding of these valuable resources. Over the years, a variety of assessment tools have been developed to help us better understand the benefits that urban forests provide and to quantify them into measurable metrics. The results they provide are extremely useful in helping to improve urban forest policies on all levels, inform planning and management, track environmental changes over time and determine how trees affect the environment, which consequently enhances human health. American Forests, with grant support from the U.S. Forest Service’s Urban and Community Forestry Program, developed this resource guide to provide a framework for practitioners interested in doing urban forest ecosystem assessments. This guide is divided into three main sections designed to walk you through the process of selecting the best urban forest assessment tool for your needs and project. In this guide, you will find: Urban Forest Management, which explains urban forest management and the tools used for effective management How to Choose an Urban Forests Ecosystem Assessment Tool, which details the series of questions you need to answer before selecting a tool Urban Forest Ecosystem Assessment Tools, which offers descriptions and usage tips for the most common and popular assessment tools available Urban Forest Management Many of the best urban forest programs in the country have created and regularly use an Urban Forest Management Plan (UFMP) to define the scope and methodology for accomplishing urban forestry goals.

  • 1 Environmental Implications of the American Forest and Paper Association's (AF&PA) Sustainable Forestry Initiative (SFI) Pr
    Environmental Implications of the American Forest and Paper Association's (AF&PA) Sustainable Forestry Initiative (SFI) Program in Comparison with the Forest Stewardship Council (FSC) Program for Forest Certification. June 1999 Sustainable Forest Initiative While the American Forest and Paper Association's (AF&PA) Sustainable Forestry Initiative (SFI) program may represent a start to make necessary improvements in US forest products industry practices, no leading environmental advocacy organizations currently endorse the program or any environmental claims arising from it. Despite SFI's tagline ("Showing the World a Higher Standard"), leading environmental groups are not convinced that the program is, in fact, showing the world an appreciably higher standard at this time. Exemplifying concern about environmental performance under SFI is the participation of The Pacific Lumber Company (Maxxam). Pacific Lumber formally complied with the requirements for SFI according to AF&PA’s annual progress reports for SFI in 1996, 1997, 1998 and 1999. Nonetheless, during this period, Pacific Lumber became well-known for its role in the Headwaters controversy over clearcutting ancient redwoods, and it had 128 citations and approximately 300 violations of the California state forest practices rules since 1995 which resulted in the suspension of its license to practice forestry in the state of California from November 1998 through early 1999. Obviously, the overall rigor of the SFI is called into serious question by such performance. By association, the performance of other AF&PA members is also called into question. The Sustainable Forestry Initiative has been developed and is administered by the American Forest and Paper Association for its members (approximately 200 companies and trade associations representing 56 million forested acres and 90% of US industrial timberlands).

A critical capacity for resilience in institutions is strategic foresight. This article reports on a project of the North American Forest Commission to use Futures Research to enhance the resilience of forest management institutions in North America. The Aspirational Futures Method was used to develop four alternative scenarios for the future of North American forests and forestry agencies: (1) an extrapolation of current trends into the expectable future titled Stressed Forests, (2) a scenario of growing desperation titled Megadisturbances Call for Military Intervention, (3) a high aspiration future titled High Tech Transformation and Cooperation, and (4) an alternative pathway to a highly preferable future titled Cultural Transformation Embraces

  • Ramping up Reforestation in the United States: a Guide for Policymakers March 2021 Cover Photo: CDC Photography / American Forests
    Ramping up Reforestation in the United States: A Guide for Policymakers March 2021 Cover photo: CDC Photography / American Forests Executive Summary Ramping Up Reforestation in the United States: A Guide for Policymakers is designed to support the development of reforestation policies and programs. The guide highlights key findings on the state of America’s tree nursery infrastructure and provides a range of strategies for encouraging and enabling nurseries to scale up seedling production. The guide builds on a nationwide reforestation assessment (Fargione et al., 2021) and follow-on assessments (Ramping Up Reforestation in the United States: Regional Summaries companion guide) of seven regions in the contiguous United States (Figure 1). Nursery professionals throughout the country informed our key findings and strategies through a set of structured interviews and a survey. Across the contiguous U.S., there are over 133 million acres of reforestation opportunity on lands that have historically been forested (Cook-Patton et al., 2020). This massive reforestation opportunity equals around 68 billion trees. The majority of opportunities occur on pastureland, including those with poor soils in the Eastern U.S. Additionally, substantial reforestation opportunities in the Western U.S. are driven by large, severe wildfires. Growing awareness of this potential has led governments and organizations to ramp up reforestation to meet ambitious climate and biodiversity goals. Yet, there are many questions about the ability of nurseries to meet the resulting increase in demand for tree seedlings. These include a lack of seed, workforce constraints, and insufficient nursery infrastructure. To meet half of the total reforestation opportunity by 2040 (i.e., 66 million acres) would require America’s nurseries to produce an additional 1.8 billion seedlings each year.
