The Harvard Forest LTER studies how forests in New England respond to natural and human disturbance and environmental change at spatial scales ranging from individual sites to the entire region. The proposed work will focus on two specific aspects of this larger mandate. First, researchers will investigate the causes and consequences of the unexpected and widespread death of oak trees on the southern New England coast. This work will be integrated with ongoing studies of similar decline in hemlock and beech trees across New England and will address the scientific and management challenges associated with the decline or loss of important ecological species. Second, a wireless (radio) network will be installed on the Prospect Hill Tract at the Harvard Forest. The wireless network will make it possible to collect data in real time from a wide range of scientific projects in the forest so that equipment may be monitored and controlled remotely and so that selected data may be posted online as it is collected.At a regional scale, the decline or loss of species caused by multiple stresses, including invasive pests and disease, climate change, and urban and suburban development, is a growing problem for scientists, policy makers, and land managers across the nation. The proposed work will shed light on the mechanisms and impacts of such events for critical tree species. At the landscape scale, recent advances in sensor, network, and wireless technologies now make it possible to conduct measurements over broad areas and at high sampling rates in a way that was unthinkable just a few years ago. The proposed wireless network at Harvard Forest will support a wide range of new studies, in effect creating an 'outdoor laboratory and classroom' for researchers and students at Harvard Forest, in the LTER Network, and in the larger scientific and educational community.

哈佛森林LTER研究新英格兰地区的森林如何在从个别地点到整个地区的空间尺度上对自然和人为干扰以及环境变化作出反应。拟议的工作将侧重于这一更大任务的两个具体方面。首先，研究人员将调查新英格兰南部海岸橡树意外大面积死亡的原因和后果。这项工作将与正在进行的有关新英格兰铁杉和山毛榉树木类似衰退的研究相结合，并将解决与重要生态物种的衰退或丧失相关的科学和管理挑战。第二，将在哈佛森林的展望山路上安装一个无线（无线电）网络。无线网络将使人们能够从森林中广泛的科学项目中实时收集数据，以便对设备进行远程监测和控制，并在收集数据时将选定的数据发布到网上。在区域范围内，物种的减少或消失是由多种压力造成的，包括入侵的害虫和疾病、气候变化、城市和郊区的发展，这对全国的科学家、决策者和土地管理者来说是一个日益严重的问题。这项工作将阐明这些事件对关键树种的机制和影响。在景观尺度上，传感器、网络和无线技术的最新进展现在使得在大范围内以高采样率进行测量成为可能，这在几年前是不可想象的。拟议中的哈佛森林无线网络将支持广泛的新研究，实际上为哈佛森林、LTER网络以及更大的科学和教育界的研究人员和学生创造一个“户外实验室和教室”。
