calc_veg_plot: aggregate vegetation parameters by plot and year

In inbo/forrescalc: Calculation of Aggregated Values on Dendrometry, Regeneration and Vegetation of Forests, Starting from Individual Tree Measures from Fieldmap

aggregate vegetation parameters by plot and year

Description

This function calculates for each plot (subplot in case of core area) and year the total coverage and the number of species in the vegetation layer. Year refers to year of the main vegetation survey (source is table "data_vegetation"), and will in some cases differ from the year of the spring flora survey.

Usage

calc_veg_plot(data_vegetation, data_herblayer)

Arguments

data_vegetation	dataframe on vegetation with variables ...
data_herblayer	dataframe on vegetation in the species level ('herb layer') with variables ...

Value

dataframe with columns plot, subplot, date, year (year of main vegetation survey, possible deviating year of spring survey not taken into account), number_of_tree_species and min/max/mid cover of the different vegetation layers (moss, herb, shrub, tree), the waterlayer and since 2015 also of the soildisturbance by game.

Examples

library(forrescalc)
# (add path to your own fieldmap database here)
path_to_fieldmapdb <-
  system.file("example/database/mdb_bosres.sqlite", package = "forrescalc")
data_vegetation <- load_data_vegetation(path_to_fieldmapdb)
data_herblayer <- load_data_herblayer(path_to_fieldmapdb)
calc_veg_plot(data_vegetation, data_herblayer)
