The five stage classes include seeds in the seed bank, new recruits or
seedlings, small vegetative plants with 1 rosette, large
vegetative plants with 2 or more rosettes, and flowering plants.
Stage classes were assigned to census plants
using a combination of status and size data recorded in the
field. See demo(stage.classify)
for more details.
