The North American Dendroecological Fieldweek (NADEF) is a work-week that teaches the tools of dendrochronology, provides networking opportunities for students and professionals, and expands the benefits of dendrochronological records to new locations. Dendrochronology is the use of tree-rings to reconstruct environmental variables. Trees record everything that effects their growth and, therefore, become useful records of environmental history. Such things as past temperature, precipitation, fire, and insect outbreaks are recorded by the trees for their entire lifetime and can be tapped for this information. Each year, the fieldweeks provide professional development to forty students and researchers interested in learning the tools of dendrochronology. Tree-ring research is only taught as a formal class in a handful of universities in the United States so most students do not have access to this training. During the fieldweek, the participants conduct five unique research projects under the guidance of an experienced dendrochronologist. These five research projects usually include a climate reconstruction, fire history, insect outbreak reconstruction, and stand-age structure analysis. The participants work up the projects from field collection, through laboratory analysis, and the week culminates in the presentation of these research projects to the other fieldweek members and to managers from the local community.With the importance of environmental change issues in today's society, the need for high resolution proxy records of climate and ecological variables is quickly growing and the tools of dendrochronology provide many of these records. This workshop will enable students to learn about the tools of dendrochronology and faculty and professionals to pick up this set of tools that are useful for ecosystem management. Understanding how forests function and what role disturbance plays in the natural balance of these forests if an important goal of today's scientists and forest managers. These fieldweeks provide the tools to study these questions and specifically provide these answers at the field stations where the fieldweek is held. The local managers will gain the results of five tree-ring based research projects on their managed lands.

北美树木生态学现场周（NADEF）是一个工作周，教授树木年代学的工具，为学生和专业人士提供网络机会，并将树木年代学记录的好处扩展到新的地点。 树木年代学是利用树木年轮重建环境变量。 树木记录了影响其生长的一切，因此成为环境历史的有用记录。 像过去的温度，降水，火灾和昆虫爆发等事情都被树木记录了一生，并且可以从中获取这些信息。 每年，fieldweeks为40名有兴趣学习树木年代学工具的学生和研究人员提供专业发展。 树木年轮研究只在美国少数几所大学作为正式课程教授，因此大多数学生无法获得这种培训。 在野外活动周期间，参与者在一位经验丰富的树木年代学家的指导下进行五个独特的研究项目。 这五个研究项目通常包括气候重建，火灾历史，昆虫爆发重建和林分年龄结构分析。 参与者从野外收集到实验室分析，并将这些研究项目介绍给其他fieldweek成员和当地社区的管理人员。随着环境变化问题在当今社会的重要性，对气候和生态变量的高分辨率代用记录的需求正在迅速增长，树木年代学工具提供了许多这样的工具记录 该研讨会将使学生了解树木年代学的工具，教师和专业人员将学习这套对生态系统管理有用的工具。 了解森林如何运作以及干扰在这些森林的自然平衡中扮演什么角色，是当今科学家和森林管理者的一个重要目标。 这些fieldweek提供了研究这些问题的工具，并特别在举办fieldweek的实地工作站提供了这些答案。 当地管理人员将在其管理的土地上获得五个基于树木年轮的研究项目的结果。
