Plant traits response to grazing
Description
Plant species cover, traits and environmental parameters recorded around livestock watering points in different habitats of central Namibian farmlands. See the Wesuls et al. (2012) paper for a full description of the data set.
Usage
data(piosphere)
Format
piosphere
is a list of 4 components.
- veg
is a data frame containing plant species cover
- traits
is a data frame with plant traits
- env
is a data frame with environmental variables
- habitat
is a factor describing habitat/years for each site
