Data from broadleaved woodlands across Great Britain, 1971

bunce71.Rd

This is the tree and environmental covariate data from a series of sites across broadleaved woodlands in Great Britain surveyed in 1971. It contains both measures of 45 tree genera measured over 103 sites and environmental data from each site. Environmental data includes the average soil pH and organic matter of each plot plus the average annual rainfall, maximum summer temperature and minimum winter temperature from 1941-1970. All climate variables were calculated based upon the HadUK-Grid climate data (Met Office et al., 2022). For more information on the sites see Wood et al. (2015).

Usage

bunce71

Format

A list that includes two data frames. The first ("abund") has 103 rows and 45 columns. Each column is a genus and each row is a site. The site identity is marked in the rownames of the data frame. Every entry is given as the number of plots that each genus appears in across the site. The second data.frame has 103 rows and 9 columns, as described below.

Site

The site identifier (103 in total)

Easting

The Easting of each site (British National Grid)

Northing

The Northing of each site (British National Grid)

Nplots

The total number of plots surveyed per site

pH

The average soil pH across the site

SOM

The average soil organic matter across the site (%)

Rainfall

The average annual rainfall in mm

SummerMaxTemp

The average maximum temperature in summer in deg Celsius

WinterMinTemp

The average minimum temperature in winter in deg Celsius
