SPRUCE Manual Phenology Observations and Photographs Beginning in 2010

Periodic observations of the phenology of vegetation bud swell, leaf out, leaf off, flowering, fruiting and the nature of snow cover and ice presence have been assessed by SPRUCE project personnel since 2010. These observations are supplemented by the collection of images from periodic photographs. Annual summaries of vegetation phenology and snow and ice presence are also provided.

Early observations were conducted throughout the S1-Bog with an emphasis on the southern end of the bog. Observations collected since the spring of 2013 have focused on the southern end of the S1-Bog and the plots 2 through 21 of the SPRUCE experiment.  Beginning in 2015 those observations included assessments within the enclosure space surrounding plots 4, 6, 8, 10, 11, 13, 16, 17, 19 and 20.  Newly collected data will be appended annually.
