Purpose of Review

Increased availability of current forest resource information provides an opportunity to evaluate the continued concerns about forest sustainability in North America. The purpose of this study is to assess and discuss the current state and trends of North American forest resources, sustainable forest management, and their implications for forest sustainability.

Recent Findings

Recent information indicates that forest sustainability in North America is not under threat. Forest area, inventory, and carbon stocks have been increasing while wood harvest has been declining. Large expanses of forest resources are covered by management plans, and many forests are certified. The areas of concern include forest fires and bark beetle infestations in primarily public forests in the western USA and Canada, and continued loss of forest cover in Mexico.

Summary

Despite progress made in gathering information on forest resources, evaluating forest sustainability remains challenging. Practicing sustainable forest management is made difficult by unfavorable market conditions and the ensuing lack of funding, challenges in developing and implementing forest management plans, and uncertainties including potential impacts of climate change, population growth, and changing markets.

可持续森林管理的当前观点：北美

审查目的

当前森林资源信息可用性的提高为评估北美地区对森林可持续性的持续关注提供了机会。本研究的目的是评估和讨论北美森林资源，可持续森林管理的现状和趋势，及其对森林可持续性的影响。

最近的发现

最新信息表明，北美的森林可持续性并未受到威胁。森林面积，库存和碳储量一直在增加，而木材采伐却在下降。经营计划涵盖了大片森林资源，并且许多森林都经过了认证。令人关注的领域包括美国西部和加拿大的主要森林中的森林大火和树皮甲虫侵扰，以及墨西哥森林覆盖率的持续下降。

概要

尽管在收集有关森林资源的信息方面取得了进展，但评估森林可持续性仍然具有挑战性。由于不利的市场条件，随之而来的资金短缺，制定和实施森林管理计划的挑战以及不确定性，包括气候变化，人口增长和市场变化的潜在影响，难以实施可持续森林管理。
