4 | Metadata | tag_2012 | unique identification number from 2012 tagging | |||||||||||||||||||||||
5 | Credits: data for 1991-2000 collected by Dr Aaron M. Elllison, 1998 - 2018 collected by Dr Leszek A. Bledzki, 2019 - 2021 collected by Dr. Jenica M. Allen | tag_2018 | unique identification number from 2018 tagging; these numbers are currently in use | |||||||||||||||||||||||
6 | Quadrat (plot aproxymately 25 x 25 m): North, Middle, South located on the top of the Prospect Hill | species | common name of the tree species | |||||||||||||||||||||||
7 | Note that each Quadrat (plot) is not perfectly square; marked by stakes in the field | latin_name | scientific name of the tree species | |||||||||||||||||||||||
8 | Maps are of unknown provinance | comments | any notes for the tree, year of notation not always included | |||||||||||||||||||||||
9 | Each measured tree has a metal tag with a unique tag number (trees have been re-tagged multiple times, latest re-tag in 2018; 2018 tags are currently in use) | year_added | the first year a tree was tagged and measured | |||||||||||||||||||||||
10 | Tag numbers prior to 2012 are included in the 'Tags & Plots' worksheet, but have not been quality controlled | year_of_mortality | the year that a tree was discovered dead | |||||||||||||||||||||||
11 | Each measured tree has a stripe of orange marking paint at dbh level | current_status | the current mortality status of an individual tree | |||||||||||||||||||||||
12 | All trees identified with common name and scientific name (provenance of IDs is unknown) | height2010_m | height of tree measured in 2010 (meters) | |||||||||||||||||||||||
13 | Dead tree are no longer measured and are shown under "curent_status" as "dead" | dbh1991_cm | diameter at breast (DBH) height of tree (centimeters) measured in 1991 | |||||||||||||||||||||||
14 | New tree are measured when they reach DBH=5 cm | 1991_flags | quality control indicator for 1991 DBH measurement | |||||||||||||||||||||||
15 | Tree Height is shown in meters (methods used to measure height are unknown) | dbh1992_cm | diameter at breast (DBH) height of tree (centimeters) measured in 1992 | |||||||||||||||||||||||
16 | Tree DBH is measured in cm once each year at the end of the growing season (late November - December) | 1992_flags | quality control indicator for 1992 DBH measurement | |||||||||||||||||||||||
