Acadia National Park pitch pine forest data
收藏资源简介:
Here you can find (almost) all data and code associated with my work as a Second Century Stewardship Fellow in Acadia National Park. I sampled pitch pine stands in the park to assess the tree's vulnerability to southern pine beetle. The data come from prism sweeps and hemispherical photos, and I measured dbh of each tree as well. As there is a 100 file limit here on Zenodo, the hemispherical photos cannot be uploaded. However, they are uploaded in our bitbucket repository, which is linked here (https://bitbucket.org/crk1025/acadia-pitch-pine-data-and-code). This repository is linked to my work as a Second Century Stewardship Fellow (https://www.scsparkscience.org). This fellowship is supported by the U.S. Department of Interior National Park Service, Schoodic Institute at Acadia National Park, the David Evans Shaw Family Foundation, and the National Park Foundation. I designed this project with advice from Dr. Jeff Garnas (my PhD advisor) and Dr. Mark Ducey. I personally collected the data when I was a PhD student at the University of New Hampshire, and this work was a chapter of my PhD. Jeff and Mark are coauthors on this work. The holistic dataset is available in the file all_data_joined.csv. The rest of the data in this repository went into the making of this holistic file. The bitbucket repository has all the files organized into folders that may make my workflow easier to understand. Descriptions of data files: all_temp_data.csv contains all temperature data. For more information about our temperature sensors, see the file temperature_logger_location_info.csv in the metadata folder. In point_meta_data.csv you will find information about each sampling point. In raw_tree_data.csv you will find information about each measured tree, including tree species and dbh. Tree species codes are available in the file tree_species_codes.csv in the metadata folder. In spb_mortality_data.csv you will find data pertinent to southern pine beetle survival, including the expected percent mortality at different temperatures. This data comes from Tran et al. 2017 (DOI: 10.1890/06-0512). Descriptions of R scripts: Some scripts are named beginning with a number: 01, 02, or 03. These need to be run in order, so that the outputs from the 01 scripts can go into the 02 script and then 03. The outputs from the 01 scripts can be found in the r_outputs folder. If the name of the script does not begin with a number, this script can be run at any point in the workflow. Each script contains notes about its contents.
