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.

Usage
