sumStrStage: sumStrStage: calculate structural stage for each plot

Description Usage Arguments Value Examples

View source: R/sumStrStage.R

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.

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.

Value

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