substrate data from Mt Moosilauke

This data is the 'long' version of the raw master file. There is a single year column, and all the variables that vary by year are now each in a single column. This dataset contains both plot-level and individual-level data. The two complementing datasets in this package (segplants and segplots)are the same as this, only the plot-level and individual-level variables have been separated (and are linked by a plot identifier 'PID').

segdata

An object of class data.table (inherits from data.frame) with 23680 rows and 45 columns.

Plot-level:
- PID: Plot identifier, this is determined by unique combinations of CONTNAM and STPACE.
- CONTNAM: Contour name
- STPACE: Beginning pace of a segment.
- ELEVCL: Elevation class
- ASPCL: Aspect class
- SOILCL[1-2]: Soil class
- HISTO: Soil type.
- SPODO: Soil type.
- INCEP: Soil type.
- MINER: ?
- ROCK: Soil type
- PHISTO: Soil type.
Individual-level:
- ID: Unique plant ID
- SPEC: Species abbreviation.
- HT: Height of plant (cm).
- STMLEN: Stem length (may differ from HT for plants that are leaning significantly).
- YEAR: Year
- YRTAG: Year a plant was initially tagged.
- ALONG: Distance from the start of the segment to a plant (cm?).
- DISUPDN: Distance up/down from segment baseline to a plant (cm?).
- YRMORT: Year of mortality
- STAT: Status of plant (live or dead)
- DECM: Decline class
- TAG: Tag assigned to plant in field (not unique in dataset).
- CHECK: ???
- CII: Crown illumination index
- PALONG: Keeper's pace from the start of the segment to the seedling/sapling, which is accurate to +/-1 pace. Similar to ALONG used in 1998/1999, but in units of 'pace'.
- SGDPS: Segment displacement from the contour in paces ('U'=up, 'D'=down). Note that these can vary across years.
- SGLEN: Segment length (m). Note this can vary between years.
- NOTE: Notes from the field.
- Data for Seedlings Only:
  - SUB: Substrate seedling was growing on.
  - SUBON: Underlying substrate (ie. the substrate under SUB).
  - BRHT: Browsing height
  - SDSP[1-2]: The first/second species where tagging of seedling ceased before the end of the segment. See also NSDSP[1-2] and DSDSP[1-2].
  - NSDSP[1-2]: Total counts of species in SDSP1/SDSP2.
  - DSDSP[1-2]: Distance from beginning of segment to where tagging ceased in a segment for species defined in SDSP1/SDSP2.
  - HRB[1-3]: Abbreviations of the three species of herbs, shrubs, or trees with the highest cover in the 50cm radius circle around a seedling. If it was a shrub ACSP or ACPE, it was recorded as 'ACSP_SH' or 'ACPE_SH'.
  - NFCVR: Percent cover in herb layer in a 50cm radius circle centered on the seedling, excluding the focal seedling.
  - TCVR: Total percent cover in herb layer (including herb, shrub, tree species <= 1m) including the seedlings in a 50cm radius circle centered on the seedling. This was collected for 1988 tagged seedlings.
