sumStrStage: calculate structural stage for each plot


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.


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



Combine data from all parks or one or more parks at a time. Valid inputs:


Includes all parks in the network


Acadia NP only


Marsh-Billings-Rockefeller NHP only


Minute Man NHP only


Morristown NHP only


Roosevelt-Vanderbilt NHS only


Saint-Gaudens NHS only


Saratoga NHP only


Weir Farm NHS only


Year to start analysis, ranging from 2006 to current year


Year to stop analysis, ranging from 2006 to current year


Allows you to remove or include QAQC events.


Default. Only returns visits that are not QAQC visits


Returns all visits, including QAQC visits


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.


Allows you to only include plots that are part of the GRTS sample design or include all plots, such as deer exclosures.


Only include plots that are part of the Vital Signs GRTS sample design


Include all plots, such as plots in deer exclosures or test plots.


Allows you to include only complete sampling events or all sampling events


Default. Only include sampling events for a plot that are complete.


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.


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