FAGUS: Retained Carbon in Beech Trees

Description

The carbon retained by leaves measured in kg/ha is recorded for forty-one different plots of mountainous regions of Navarre (Spain), depending on the forest classification: areas with 90% or more beech trees (Fagus Sylvatica) are labeled monospecific, while areas with many species of trees are labeled multispecific.

Usage

FAGUS

Format

A data frame with 41 observations on the following 3 variables:

• plot (plot number)

• carbon (carbon retained by leaves measured in kg/ha)

• type (a factor with levels monospecific and multispecific)
