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

"SARA"

Saratoga NHP only

"WEFA"

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

dist_m

Filter trees by a distance that is less than or equal to the specified distance in meters of the tree to the center of the plot. If no distance is specified, then all trees will be selected. For example, to select an area of trees that is 100 square meters in area, use a distance of 5.64m.

valueType

Allows you to return cover class midpoints (numeric) or coverclass ranges (text)
