calcStrStage: calcStrStage: calculate structural stage for each plot

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

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 automartically assigned those classes in the calculation. Must run importData first.

Usage

calcStrStage(
  park = "all",
  QAQC = FALSE,
  locType = "VS",
  panels = 1:4,
  from = 2007,
  to = 2019,
  output,
  speciesType = c("all", "native", "exotic"),
  ...
)

Arguments

park	Combine data from all parks or one park at a time. Acceptable options are: "all" Includes all parks in the network "APCO" Appomattox Court House NHP only "BOWA" Booker T. Washington NM only "COLO" Colonial NHP only "FRSP" Fredericksburg & Spotsylvania NMP only "GETT" Gettysburg NMP only "GEWA" George Washington Birthplace NM only "HOFU" Hopewell Furnace NHS only "PETE" Petersburg NBP only "RICH" Richmond NB only "SAHI" Sagamore Hill NHS only "THST" Thomas Stone NHS only "VAFO" Valley Forge NHP only
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
locType	Allows you to only include plots that are part of the GRTS sample design or include all plots, such as deer exclosures "VS" Default. Only include plots that are part of the Vital Signs GRTS sample design "all" Include all plots, such as deer exclosures and bonus plots
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.
from	Year to start analysis, ranging from 2007-2019
to	Year to stop analysis, ranging from 2007-2019
speciesType	Allows you to filter on native, exotic or include all species. "all" Default. Returns all species. "native" Returns native species only "exotic" Returns exotic species only

Value

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

Examples

importData() #imports using default odbc
stage_df <- calcStrStage(park = 'FRSP', from = 2015, to = 2018)
