joinCWDData: joinCWDData: compile coarse woody debris data.

In KateMMiller/forestMIDNarch: Package for importing, joining and querying MS Access based MIDN forest database tables.

Description

This function combines calculates CWD volume for each plot. Must run importData first. Note that plots in Deer Exclosures are not sampled for CWD and will not be returned.

Usage

joinCWDData(
  units = c("ha", "acres"),
  park = "all",
  from = 2007,
  to = 2019,
  QAQC = FALSE,
  locType = "VS",
  output,
  ...
)

Arguments

units

Calculates CWD Volume based on different units. "ha" Default. Returns CWD volume as cubic m/hectare "acres" Returns CWD volume as cubic ft/ acre

Value

returns a dataframe with CWD volume for each plot, one with cubic m/ha and cubic ft/acre

Examples

importData() #imports using default odbc
# Compile CWD data for FRSP for most recent survey and return in ft^3/acre
cwd_data <- joinCWDData(park = 'FRSP', from = 2015, to = 2018, units = 'acres')

# Compile CWD data for all parks (default) for most recent survey and return in m^3/ha (default)
cwd_data <- joinCWDData(from = 2015, to = 2018)
