Morton Forestry Plots: Minirhizotrons and Roots (3.63437)
Date: 2019Type: Dataset
Description:Minirhizotron tubes were installed in 18 Forestry plots covering 13 species around The Morton Arboretum in the early summer of 2018. Beginning in spring of 2019, images are being collected on a roughly bi-weekly to monthly time scale from the tubes using a minirhizotron camera. From these images, the seasonal growth patterns and lifespan of fine roots can be monitored.
Final datasets will be made free and publicly accessible through the Fine-Root Ecology Database (FRED; http://roots.ornl.gov/). Raw data may be made available with reasonable request.
Morton Forestry Plots: Dendrometer Bands and Woody Stems (3.63438)
Date: 2019Type: Dataset
Description:"TreeHugger" Digital dendrometers were installed on 87 trees across the 18 core Forestry Plots in April of 2019. From these, measurements of stem diameter will be recorded every 15 minutes continuously across the year. The measurements have an accuracy of approximately 50 microns, enabling the monitoring of both seasonal patterns of stem growth as well as diurnal patterns of stem shrinking and swelling associated with water loss and gain within the tree trunk.
Raw and cleaned data may be made available from the Root Lab with reasonable request. Final datasets will also be housed at Oak Ridge National Laboratory.
Morton Forestry Plots: Phenocams and Leaves (3.63439)
Date: 2019Type: Dataset
Description:Time-lapse "Phenocams" (Trail Cams) have been installed around the Arboretum targeting the 18 core Forestry Plots. These cameras capture a series of images of the leaf canopy 5 to 24 times each day throughout the year. The recorded images will then be analyzed by the field-specific software, PhenocamW64, which will estimate a greenness index representing the timing of leaf production, senescence, and relative density of tree canopy across the year.
Raw and clean data may be made available from the Root Lab with reasonable request. Final datasets will also be housed at Oak Ridge National Laboratory.
