## [1] "No anomalous measurements at the moment."
This repository contains dendrometer bands data for the SCBI ForestGEO plot. There are two sets of measurements:
- Biannual dendrometer bands - dendrometer bands on >500 trees measured at start and end of growing season: 2010 - present
- Intra-annual (i.e. biweekly) dendrometer bands - dendrometer bands on >150 trees measured around every 2 weeks during growing season: 2011 - present
This data exists in two forms:
- Raw data based on field collection forms.
- Post-processed
data
in the
scbi.dendroAll_YEAR.csvfiles. This is the data to be used for analysis.
Whenever raw data is pushed to GitHub, GitHub Actions continuous
integration follows the steps in
.github/workflows/QA_QC_checks.yaml,
which automatically 1) takes the raw data and produces the
post-processed data and 2) performs data QA/QC
To learn how to address both 1) code scripting and 2) data collection errors identified by GitHub Actions, watch this screencast training video.
- Biannual dendrometer bands - In 2010, 243 bands were initially installed, additional bands were installed in 2011 and currently more than 515 stems of various DBH (5.5-152 cm) are being monitored. Protocols for band installations and remeasurement are published here (original protocol; latest protocol).
- Intra-annual dendrometer bands - Since 2011, ~155 stems of DBH ranging from 6-148 cm are monitored biweekly during the growing season each year.
- field_forms and raw_data are pulled from the year’s master file via R-scripts
- maps are generated based on the current list of trees with dendrobands.
- data recorded in the field are entered in raw_data and immediately merged into the current year’s master file using an R script.
A dataset for each year of collection is found in the data folder. Each year has a master data set that includes both biannual and intra-annual surveys (with a file name format “scbi.dendroAll_YEAR.csv”)
In the interest of keeping survey data entry simplified, each type of survey (biannual and intra-annual) has its own .csv for data entry for the current year. This is where the current year’s data will be entered during the growing season (March – November). When the growing season is finished and the November biannual survey is complete, data should be transferred to the scbi.dendroAll_YEAR.csv via joining/merging in R. 1. Metadata for these individual forms are consistent with the scbi.dendroAll_YEAR.csv metadata (the master).
A summary of tree species by survey type per year (ie. dbh range) are available here.
Some relevant data on dendrometer banded trees (geographic location, date started/end, mortalitity year, etc) is available here dendro_trees.csv.
Collection of these data is a collaboration between the Anderson-Teixeira and McShea labs. These data formerly lived on the McShea V: drive (V:/SIGEO/DENDROMETRY/Dendrobands), and are now managed in this GitHub repository by the Anderson-Teixeira lab. Access is provided to any McShea lab member via SCBI-ForestGEO-guest, the password for which is stored in the V: drive.
