Chiapas: Tree abundance in tropical montane forest plots

Description

Tree abundance in 224 0.1-ha plots in three montane cloud forest regions of Chiapas, Mexico.

Usage

data(Chiapas)

Format

The Chiapas data set contains data for 375 tree species (columns) from 224 0.1-ha plots (rows). The first column is a factor with three levels with the name of the region.

Details

This data set characterizes tree communities from tropical montane cloud forests in three regions of the state of Chiapas, Mexico: El Triunfo Biosphere Reserve in Sierra Madre (100 plots), the Highlands (38 plots), and the Northern Mountains (86 plots). For these plots, incidence records were based on trees exceeding 5 cm in diameter at breast height. Data were obtained from the BIOTREE-NET website (www.biotreenet.com). Species names were standardized and typographical errors were corrected using The Plant List through the Taxostand package (Cayuela et al. 2012). Distance between regions ranged from ca. 50 kms (the Highlands and Northern Mountains) to ca. 250 kms (El Triunfo and Northern Mountains).
