data_v4 {MLFS} | R Documentation |
This is simulated data that reassemble the national forest inventory data. We use it to show how to run examples for predicting tree mortality. Mortality occurs in the middle of a simulation step, so all variables have the preposition 'mid'
data_v4
A data frame with 6855 rows and 41 variables:
year in which plot was visited
a unique identifier for plot
a unique identifier for tree
identifier for species group
status of a tree: 0 (normal), 1(harvested), 2(dead), 3 (ingrowth)
species name
slope on a plot
plot elevation
plot northness, 1 is north, 0 is south
a proxy for site index, higher value represents more productive sites
monthly precipitation sum
monthly mean temperature
basal area of individual trees in m2 in the middle of a simulation step
basal area increment in the middle of a simulation step
upscale weight to calculate hectare values in the middle of a simulation step
tree height in meters in the middle of a simulation step
crown height in meters in the middle of a simulation step
tree volume in m3 in the middle of a simulation step
Basal Area in Large trees the middle of a simulation step
Total stand basal area the middle of a simulation step
The number of trees in a stand the middle of a simulation step
