Cary spongy moth larval data

The Forest Response to Stress and Damage (frequently referred to as FORSTAD) and long term forest monitoring project began in 1992 to study how mixed-oak forests respond to multiple forms of environmental change. The research took place at Cary Institute of Ecosystem Studies in the Hudson Valley of New York. FORSTAD included several sub-projects including (1) air pollution and nutrient cycling dynamics, (2) spongy moth population dynamics, (3) small mammal dynamics and (4) vegetation dynamics. This dataset is a contribution to the Cary Institute of Ecosystem Studies, and is part of the Long term monitoring of forest ecosystems: Cary spongy moth dynamics.To understand the impacts of spongy moth, a non-native forest pest, every stage of the spongy moth life cycle was monitored. This included counts of spongy moths in each life stage as well as the effects of the caterpillar’s consumption of forest trees. The measurements included spongy moth egg mass density and fecundity, egg mass hatch and parasitism, late instar larval density, pupal density (at high density), canopy photos to estimate defoliation, visual estimate of defoliation, mechanisms of moth release, including white footed mouse and chipmunk removals in 1995, 1997 and 1998, larval &amp; pupal persistence, pupal predation, natural pupation and pupal viral analysis.The data included here are spongy moth larval density data collected at each of the FORSTAD grids and North Canoe Hill. Some of the data were collected prior to the onset of the FORSTAD project.<b>File list:</b>Spongy_Moth_Larval_Density_Metadata_public.pdf - contains complete project metadata, personnel, methodology, and definitions for data variables in all data files.FORSTAD_North_Canoe_Hill_Larval_Data_1995_1998.csvFORSTAD_Red_Exp_Larval_Data_1995_1998.csvFORSTAD_Red_Control_Larval_Data_1992_1998.csvFORSTAD_Green_Exp_Larval_Data_1995_1998.csvFORSTAD_Green_Control_Larval_Data_1995_1998.csvFORSTAD_Yellow_Exp_Larval_Data_1995_1998.csvFORSTAD_Yellow_Control_Larval_Data_1992_1998.csvFORSTAD_ Larval_Summary_Data_1995.csvSee Related Materials for more data from the spongy moth sub-project.

森林胁迫与损伤响应（Forest Response to Stress and Damage，常简称为FORSTAD）长期森林监测项目于1992年启动，旨在探究混交栎林对多种环境变化的响应机制。本研究的实施地点位于纽约哈德逊谷的卡里生态系统研究所（Cary Institute of Ecosystem Studies）。FORSTAD包含4个子项目，分别为：（1）空气污染与养分循环动态；（2）舞毒蛾（spongy moth）种群动态；（3）小型哺乳动物动态；（4）植被动态。

本数据集为卡里生态系统研究所的共建数据，隶属于“森林生态系统长期监测：卡里舞毒蛾动态”项目。为明确外来森林害虫舞毒蛾的危害，项目对其生命周期的各个阶段开展了全面监测，监测内容涵盖各生命阶段的舞毒蛾种群数量统计，以及其幼虫取食林木造成的影响。具体监测指标包括：舞毒蛾卵块密度与繁殖力、卵块孵化率与寄生率、高龄幼虫密度、高密度种群下的蛹密度、用于评估落叶程度的冠层照片、落叶程度目视估算、舞毒蛾种群调控机制（含1995、1997及1998年对白足鼠和花栗鼠的移除实验）、幼虫与蛹的留存率、蛹捕食率、自然化蛹情况以及蛹病毒分析。

本次发布的数据为在所有FORSTAD样地以及北独木山（North Canoe Hill）采集的舞毒蛾幼虫密度数据，其中部分数据采集于FORSTAD项目启动之前。
