Variables
Variables (legacy): 

Year

  • Label: Year
  • Definition: Year sampling was performed
  • Type: Date/time
  • Date format: YYYY
  • Missing values: None specified

,
Species

  • Label: Tree Species
  • Definition: A coded indicator of the tree species associated with the sample. Coding pattern combines the first two letters of the genus and species. For example, Acer Rubrum (red maple) is coded ACRU.
  • Type: Code list
  • Codes:
    • ACRU = Acer rubrum
    • ACSA = Acer saccharum
    • BEPA = Betula papyrifera
    • PIST = Pinus strobus
    • POGR = Populus grandidentata
    • POTR = Populus tremuloides
    • QURU = Quercus rubra
  • Missing values: None specified

,
[YEAR]_DBH(0.1_inch)

  • Label: [YEAR]_DBH(0.1_inch)
  • Definition: Year-wise tree dbh measured to 0.1 inch
  • Type: Physical quantity
  • Unit: inch
  • Maximum: Not specified
  • Minimum: Not specified
  • Precision: 0.1
  • Missing values: None specified

,
Acronym

  • Label: Acronym
  • Definition: Standardized code for individual species. See "MichiganPlants" file for code definitions.
  • Type: Nominal
  • Missing values: None specified

,
Count.saplings

  • Label: Count.saplings
  • Definition: The species-wise count of trees above 1 foot tall, and below 4.5 feet tall
  • Type: Nominal
  • Missing values: None specified

Methods: 

In 1969, 1973, 1978, 1983, 1988, and 1998, DBH values for every tree above 4.5 feet tall were recorded. In years except 1979, 1983, and 1988, the species-wise counts of saplings >1 ft tall were also recorded (except plot 105). NEED VERIFICATION FROM BVK RE: SAMPLING METHODS.
