Usage

pp_raw

Format

A data frame with 19011 rows and 43 variables.

• PPLOT: Permanent plot number

• SPLOT: Subplot number

• SPLOT98: Subplot number before correction in 2010.

• SPCRT: '1' if it is a subplot that got corrected after 1998 basing on BQUDX/BQUDY data.

• BQUDX: Quadrat number along X-axis (North -> West). When missing, same procedure was followed as that for BQCRDX.

• BQUDY: Quadrat number along Y-axis (North -> East). Same qualifications as BQUDX.

• BQCRDX: Distance along X axis (North -> West) within a 2x2 quadrat from center of the plant. Only recorded for 1986 tagged trees, 1987 tagged trees and saplings, 1988 tagged saplings, and 1998 tagged trees and saplings. When missing, and BPCRDX or BPCRDY were available, they were calculated from those variables.

• BQCRDY: Distance along Y axis (North -> East) within 2x2 quadrat. Same qualifications as BQCRDX.

• BPCRDX: Distance along X axis (North -> West) from center of the plant within the whole plot. When missing, this variable was calculated from BPCRDX and BPCRDY, or BQUDX and BQUDY.

• BPCRDY: Distance along Y axis (North -> East) from center of the plant within the whole plot. Same qualifications as BPCRDX.

• CQUDX86: Quadrat number along X axis (North -> West) from center of tree crown collected in 1986 only.

• CQUDY86: Quadrat number along Y axis (North -> East) from center of tree crown collected in 1986 only.

• CQCRDX86: Distance along the X axis (North -> West) with 2x2 meter quadrat from the center of the crown. Collected in 1986 only.

• CQCRDY86: Distance along the Y axis (North -> East) with 2x2 meter quadrat from the center of the crown. Collected in 1986 only.

• CSAP[8788|98]: Indicates if all saplings (by species) in a subplot were tagged ('Y'/'N'). In 2010 census, all species were tagged in all 4 subplots. In 1987/1988 'PIRU' were tagged in all 4 subplots. In 1998, 'PIRU' and 'BECO' were tagged in all 4 subplots.

• TAG: Tree tag number used since 1998. Duplicated tags were marked (add .1 to the duplicated TAG number).

• TAGOLD: Old tag numbers used in 1986, 1987, 1988.

• SPEC: Tree species abbreviation

  • ABBA: Abies balsamea (Balsam Fir)

  • PIRU: Picea rubens (Red Spruce)

  • BECO: Betula cordifolia (Mountain Paper Birch)

  • BEAL: Betula alleghaniensis (Yellow Birch)

  • BEPA: Betula papyrifera (Paper Birch)

  • SOAM: Sorbus americana (Mountain Ash)

  • UNID: Unidentified

  • ”: Missing

• CLASS: Type of sampling location

  • P: Permanent Plot

  • A: Additional spruce 'ears'

  • M: Met station plots.

• YRTAG: Tagging year. For 86, 87, 88, 98 tagged plants, this was derived from CENSUS1/CENSUS2. In 2010, this was derived from merging 2010 data with data collected before.

• YRREC: Year of recruitments. Except the first census year, for trees, this is equal to YRTAG; and for saplings, this depends on YRTAG and whether this subplot was looked for sapling in previous census (CSAP8687 and CSAP98).

• STAT86: 'ALIVE' or 'DEAD'. Status for 1986 tagged trees in regular east side permanent plots and additional spruce ears.

• STAT87: 'ALIVE' or 'DEAD'. Status for 1987 tagged trees in regular west permanent plots, additional spruce ears, and saplings in regular west side plots.

• STAT88: Status for 1988 tagged saplings in regular east and west side permanent plots and re-measurements for 1986 tagged trees. Only new live saplings were tagged in 1988, so STAT88 for them are all equal to 'ALIVE'. STAT88 for 86 trees were created based on DECM88.

• STAT89: Status for previously tagged 'PIRU' trees and saplings, which were created based on DECM collected for winter injury data in 1989.

• STAT98: 'ALIVE', 'DEAD', 'NF', 'PD'. 'NF' means not found, 'PD' means probably dead.

• STAT10: Status for previously tagged plants and newly tagged trees/saplings in regular plots and spruce ears. Some plants that were dead in 1998 were also collected for status in 2010. Possible values are 'ALIVE', 'DEAD', 'NF', 'NFC' (for additional spruce, field crew didn’t bring old data sheet during data collection, which means they didn’t look for specific additional spruces. So if a status was missing (assumed it was not found) for additional spruce).

• YRCA: Year of 'come back alive'. It’s equal to 1988 or 2010. Four plants only. There might be plants that were identified as dead in 1986/1987 but came back alive in 1998.

• YRMORT: Year of mortality. It’s equal to 1986, 1987, 1988, 1989, 1998, 2010, or 2011. When it’s missing, it means until the last year when a STAT was collected, the plant was still alive. This was recorded for as 1986, 1987, and 1998 or missing in mas98.ssd, and was updated after adding in 1988 re-measurement, 1989 winter injury data, 2010 data, and 2011 field check.

• DBH86: DBH measurements collected in 1986 for permanent regular trees (>=5cm) and additional spruce tree on plot 1~15.

• HTTCR86: Height to the top of live crown collected for 1986 tagged trees. This was NOT collected for all trees; some trees weren’t collected for height in 1986 were collected for height in 1987. For plot 14 and 15, Heights were only collected in subplot 2 in 1987.

• CRHT86: Crown height (from base of crown to top) collected in 1986, which is equal to HTTCR86-HTBCR86 (height to the base of the crown).

• CLONG86: The longest width of a tree crown collected in 1986.

• CAZLNG86: Azimuth of the longest portion of a tree’s crown. This was always collected when CLONG86 and CPERP86 were collected except one tree.

• CPERP86: Width in the perpendicular direction of the longest portion of the crown. Not collected for all trees.

• DECM86: Decline status of trees in 1986 (values 1-5).

• HTTCR87: Height to the top of live crown collected for trees and saplings tagged in 1987 (for trees mostly only for PIRU) and some trees tagged in 1986. Note that most tagged trees are missing heights in 1987 (and only a few saplings).

Notes: Some DBH98 were missing. If DBH98 is equal to 0 for a dead plant, it was set as missing. Heights were measured vertically, so a plant that had a leaning length of greater than 1.35 meters may still not have a DBH.

• TOTHT98: Total height measured in 1998 for both trees and saplings. It's the height to the dead top when a tree had a dead top, and it would be larger than HTTCR98 in those cases. When a tree did not have a dead top, TOTHT98 is equal to HTTCR98.
