sumStrStage: calculate structural stage for each plot

Description

This function calculates structural stage metric from Ecological Integrity Scorecard, which assigns Pole, Mature, Late Successional, or Mosaic (i.e., none of the above) to each plot based on the percent of live basal area of canopy trees in pole, mature and large size classes. Plots must be closed-canopy forest to be classified for this metric. Therefore plots classified as Woodlands (ACAD only) or Early successional (SARA only) in the field are automatically assigned those classes in the calculation. Must run importData first.

Usage

sumStrStage(
  park = "all",
  from = 2006,
  to = as.numeric(format(Sys.Date(), "%Y")),
  QAQC = FALSE,
  panels = 1:4,
  locType = c("VS", "all"),
  eventType = c("complete", "all"),
  ...
)

Arguments

park	Combine data from all parks or one or more parks at a time. Valid inputs: "all" Includes all parks in the network "ACAD" Acadia NP only "MABI" Marsh-Billings-Rockefeller NHP only "MIMA" Minute Man NHP only "MORR" Morristown NHP only "ROVA" Roosevelt-Vanderbilt NHS only "SAGA" Saint-Gaudens NHS only "SARA" Saratoga NHP only "WEFA" Weir Farm NHS only
from	Year to start analysis, ranging from 2006 to current year
to	Year to stop analysis, ranging from 2006 to current year
QAQC	Allows you to remove or include QAQC events. FALSE Default. Only returns visits that are not QAQC visits TRUE Returns all visits, including QAQC visits
panels	Allows you to select individual panels from 1 to 4. Default is all 4 panels (1:4). If more than one panel is selected, specify by c(1, 3), for example.
locType	Allows you to only include plots that are part of the GRTS sample design or include all plots, such as deer exclosures. "VS" Only include plots that are part of the Vital Signs GRTS sample design "all" Include all plots, such as plots in deer exclosures or test plots.
eventType	Allows you to include only complete sampling events or all sampling events "complete" Default. Only include sampling events for a plot that are complete. "all Include all plot events with a record in tblCOMN.Event, including plots missing most of the data associated with that event (eg ACAD-029.2010). This feature is currently hard-coded in the function.
...	Other arguments passed to function.

Value

returns a dataframe with structural stage and metrics used to assign stages to plots.

Examples

## Not run: 
importData()
stage_df <- sumStrStage(park = 'MABI', from = 2016, to = 2019)

## End(Not run)
