avoca {ecotraj}

Avoca permanent plot dataset

Description

Example dataset with data from 8 permanent forest plots located on slopes of a valley in the New Zealand Alps. The study area is mountainous and centered on the Craigieburn Range (Southern Alps), South Island, New Zealand. Forests plots are almost monospecific, being the mountain beech (Fuscospora cliffortioides) the main dominant tree species. Previously forests consisted of largely mature stands, but some of them were affected by different disturbances during the sampling period (1972-2009) which includes 9 surveys.

Format

Three data items are included:

avoca_strat

An object of class stratifiedvegdata (see function stratifyvegdata from package 'vegclust') with structural and compositional data.

avoca_sites

A vector identifying sampled sites of each element in avoca_strat.

avoca_surveys

A vector identifying surveys of each element in avoca_strat.
