Spring and Fall Leaf Phenology from Coweeta LTER Soil Moisture Sites SM1 & SM2, Coweeta Hydrologic Laboratory, Otto, NC, 2003-2015

Spring vegetative bud break, leaf elongation, fall leaf color, and leaf senescence are monitored at the two scaffold towers located at Project 1040 soil moisture microclimate sites 2 and 4. We have identified a variety of species at the elevation extremes within the Coweeta basin for this yearly monitoring project.

本年度监测项目针对春季营养芽萌发、叶片伸长、秋季叶色变化及叶片衰老四类指标开展观测，监测点位设置于1040项目土壤湿度微气候（soil moisture microclimate）站点2号与4号处的两座支架塔（scaffold towers）上。本项目已在考伊塔盆地（Coweeta basin）内的海拔极值区域识别出多种物种。
