BSsucc: Secondary succession data

Description

Functional group abundances (herbaceous annual, herbaceous perennial, woody) from one of the fields in the Buell-Small long term succession study (http://www.ecostudies.org/bss/). Data are based on visual estimates of percent cover, using annual means of each species, which are then summed for each functional group.

Format

A data frame with 147 observations on the following 3 variables.

variable

plant functional type; a factor with levels Annual, Perennial, Woody

value

a numeric vector
