  • Protect Us from Climate Change
    INTRODUCTION This project documents both the existing value and potential of New England’s working forest lands: Value – not only in terms of business opportunities, jobs and income – but also nonfinancial values, such as enhanced wildlife populations, recreation opportunities and a healthful environment. This project of the New England Forestry Foundation (NEFF) is aimed at enhancing the contribution the region’s forests can make to sustainability, and is intended to complement other efforts aimed at not only conserving New England’s forests, but also enhancing New England’s agriculture and fisheries. New England’s forests have sustained the six-state region since colonial settlement. They have provided the wood for buildings, fuel to heat them, the fiber for papermaking, the lumber for ships, furniture, boxes and barrels and so much more. As Arizona is defined by its desert landscapes and Iowa by its farms, New England is defined by its forests. These forests provide a wide range of products beyond timber, including maple syrup; balsam fir tips for holiday decorations; paper birch bark for crafts; edibles such as berries, mushrooms and fiddleheads; and curatives made from medicinal plants. They are the home to diverse and abundant wildlife. They are the backdrop for hunting, fishing, hiking, skiing and camping. They also provide other important benefits that we take for granted, including clean air, potable water and carbon storage. In addition to tangible benefits that can be measured in board feet or cords, or miles of hiking trails, forests have been shown to be important to both physical and mental health. Beyond their existing contributions, New England’s forests have unrealized potential.

  • Forest Dieback/Damages in European State Forests and Measures to Combat It Several EUSTAFOR Members Have Recently Experienced An
    Forest dieback/damages in European State Forests and measures to combat it Several EUSTAFOR members have recently experienced and reported on severe cases of forest dieback, caused by different biotic and abiotic agents. To get a better overview of these events and their consequences, with a view to a possible exchange of experiences among EUSTAFOR members as well as the development of proposals on how to communicate on these issues, the EUSTAFOR Office sent a short questionnaire to SFMOs in Europe. What follows is a comprehensive summary of the key information we received from our members. Results Out of 19 responses, 17 experienced forest dieback/damage to their forests. Only Romania and Ireland reported no forest dieback. However, Coillte (Ireland) is experiencing the problem with certain species, so they answered accordingly. Due to EUSTAFOR’s membership structure in some countries, we received input from more than one organization in that country. For example, in Germany, five different regional forest enterprises responded to the survey and, in Bulgaria, information came from two sources: the governing body - Executive Forest Agency (Ministry of Agriculture and Foods) and from one of the regional forestry enterprises. The reporting period relates to the most current available data. For the majority of the reports, this is 2018-2019. A few members, however, reported data that is a bit older.

Received: 2 June 2020; Accepted: 21 July 2020; Published: 23 July 2020 Abstract: Background and Objectives: Under the Paris Agreement, the European Union (EU) sets rules for accounting the greenhouse gas emissions and removals from forest land (FL). According to these rules, the average FL emissions of each member state in 2021–2025 (compliance period 1, CP1) and in 2026–2030 (compliance period 2, CP2) will be compared to a projected forest reference level (FRL). The FRL is estimated by modelling forest development under fixed forest management practices, based on those observed in 2000–2009. In this context, the objective of this study was to estimate the effects of large-scale uptake of alternative forest management models (aFMMs), developed in the ALTERFOR project (Alternative models and robust decision-making for future forest management), on forest harvest and forest carbon sink, considering that the proposed aFMMs are expanded to most of the suitable areas in EU27+UK and Turkey.

  • Limiting the High Impacts of Amazon Forest Dieback with No-Regrets Science and Policy Action PERSPECTIVE David M
    PERSPECTIVE Limiting the high impacts of Amazon forest dieback with no-regrets science and policy action PERSPECTIVE David M. Lapolaa,1, Patricia Pinhob, Carlos A. Quesadac, Bernardo B. N. Strassburgd,e, Anja Rammigf, Bart Kruijtg, Foster Brownh,i, Jean P. H. B. Omettoj, Adriano Premebidak, Jos ´eA. Marengol, Walter Vergaram, and Carlos A. Nobren Edited by B. L. Turner, Arizona State University, Tempe, AZ, and approved October 1, 2018 (received for review May 8, 2018) Large uncertainties still dominate the hypothesis of an abrupt large-scale shift of the Amazon forest caused by climate change [Amazonian forest dieback (AFD)] even though observational evidence shows the forest and regional climate changing. Here, we assess whether mitigation or adaptation action should be taken now, later, or not at all in light of such uncertainties. No action/later action would result in major social impacts that may influence migration to large Amazonian cities through a causal chain of climate change and forest degradation leading to lower river-water levels that affect transportation, food security, and health. Net-present value socioeconomic damage over a 30-year period after AFD is estimated between US dollar (USD) $957 billion (×109) and $3,589 billion (compared with Gross Brazilian Amazon Product of USD $150 bil- lion per year), arising primarily from changes in the provision of ecosystem services. Costs of acting now would be one to two orders of magnitude lower than economic damages. However, while AFD mitigation alternatives—e.g., curbing deforestation—are attainable (USD $64 billion), their efficacy in achieving a forest resilience that prevents AFD is uncertain.

  • 4 Air Pollution Impacts on Forests in a Changing Climate
    GLOBAL ENVIRONMENTAL CHANGES 4 Air Pollution Impacts on Forests in a Changing Climate Convening lead author: Martin Lorenz Lead authors: Nicholas Clarke and Elena Paoletti Contributing authors: Andrzej Bytnerowicz, Nancy Grulke, Natalia Lukina, Hiroyuki Sase and Jeroen Staelens Abstract: Growing awareness of air pollution effects on forests has, from the early 1980s on, led to intensive forest damage research and monitoring. This has fostered air pollution control, especially in Europe and North America, and to a smaller extent also in other parts of the world. At several forest sites in these regions, there are first indications of a recovery of forest soil and tree conditions that may be attributed to improved air quality. This caused a decrease in the attention paid by politicians and the public to air pollution effects on forests. But air pollution continues to affect the structure and functioning of forest ecosystems not only in Europe and North America but even more so in parts of Russia, Asia, Latin America, and Africa. At the political level, however, attention to climate change is focussed on questions of CO2 emission and carbon sequestration. But ecological interactions between air pollution including CO2 and O3 concentrations, extreme temperatures, drought, insects, pathogens, and fire, as well as the impact of ecosystem management practices, are still poorly under- stood. Future research should focus on the interacting impacts on forest trees and ecosystems. The integrative effects of air pollution and climatic change, in particular elevated O3, altered nutrient, temperature, water availability, and elevated CO2, will be key issues for impact research. An important improvement in our understanding might be obtained by the combination of long-term multidisciplinary experiments with ecosystem-level monitoring, and the integration of the results with ecosystem modelling within a multiple-constraint framework.

  • Predicting Forest Dieback in Maine, USA: a Simple Model Based on Soil Frost and Drought
    687 Predicting forest dieback in Maine, USA: a simple model based on soil frost and drought Allan N.D. Auclair, Warren E. Heilman, and Blondel Brinkman Abstract: Tree roots of northern hardwoods are shallow rooted, winter active, and minimally frost hardened; dieback is a winter freezing injury to roots incited by frost penetration in the absence of adequate snow cover and exacerbated by drought in summer. High soil water content greatly increases conductivity of frost. We develop a model based on the sum of z-scores of soil frost (December–February) and drought in summer (May–September) that accurately predicts timing and severity of dieback on sugar maple (Acer saccharum Marsh.), Betula spp., Fraxinus spp., and red spruce (Picea rubens Sarg.) in Maine, USA, during 1920–1995. Discrepancies between predicted and actual dieback relate largely to tree popu- lation dynamics. Extraordinary levels of dieback on Betula during 1935–1950 occurred under low stress but in mature pop- ulations; under high climate stress during 1951–1975, younger surviving Betula proved resistant and showed little dieback. Severe dieback in Acer stands during 1975–1995 may relate to extensive partial cutting, leaving stands open to frost and high water tables. Widespread use of forwarder feller/buncher and wheeled skidders after 1960 commonly left hummocky, irregular surfaces subject to pooling and accelerated frost penetration. Silvicultural applications include modifying harvest- ing practices to minimize frost complications and use of the model to track and map climatic risk to avoid conditions and locales subject to dieback. Re´sume´ : Les racines des feuillus nordiques sont peu profondes, actives en hiver et a` peine endurcies au froid; le de´pe´ris- sement est le re´sultat de dommages aux racines dus au gel hivernal qui pe´ne`tre dans le sol a` cause d’un couvert nival in- suffisant et ces dommages sont aggrave´s par la se´cheresse estivale.
