joinTreeFoliageCond: compiles live tree foliage data


This function compiles live tree foliage condition data into a wide format with one row per tree visit and a column for each foliage condition type. Must run importData first. Abandoned plots and incomplete visits are excluded from function.


  park = "all",
  from = 2006,
  to = as.numeric(format(Sys.Date(), "%Y")),
  locType = c("VS", "all"),
  panels = 1:4,
  speciesType = c("all", "native", "exotic", "invasive"),
  canopyPosition = c("all", "canopy"),
  dist_m = NA,
  valueType = c("midpoint", "classes")



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 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 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 filter on native, exotic or include all species.


Default. Returns all species.


Returns native species only


Returns exotic species only


Allows you to filter on tree crown class


Returns all canopy positions


Returns only dominant, codominant, and intermediate crown classes. Since only live trees are assigned crown classes, this also only returns live trees.


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.


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


Default. Returns cover class midpoints


Returns the text coverclass definitions


returns a wide dataframe with one row for each live tree visit and foliage conditions as columns.
