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

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.

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.

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

"invasive"

Returns species on the Indicator Invasive List

canopyForm

Allows you to filter on canopy species only or include all species.

"all"

Returns all species, including low canopy species.

"canopy"

Default. Returns canopy-forming species only

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. This feature is currently hard-coded in the function.

units

Allows you to choose which metric to calculate: basal area or stem density

"density"

Default. Returns stems/ha

"BA"

Returns basal area in sq.m/ha

"both"

Returns noth stem density and BA/ha.

Value

returns a dataframe with one row for each plot and either density, BA or both in 1cm size classes.
