#' Data from broadleaved woodlands across Great Britain, 1971
#'
#' 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).

#' @format A list that includes two data frames. The first (\code{"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.
#'
#' \describe{
#'   \item{Site}{The site identifier (103 in total)}
#'   \item{Easting}{The Easting of each site (British National Grid)}
#'   \item{Northing}{The Northing of each site (British National Grid)}
#'   \item{Nplots}{The total number of plots surveyed per site}
#'   \item{pH}{The average soil pH across the site}
#'   \item{SOM}{The average soil organic matter across the site (%)}
#'   \item{Rainfall}{The average annual rainfall in mm}
#'   \item{SummerMaxTemp}{The average maximum temperature in summer in deg Celsius}
#'   \item{WinterMinTemp}{The average minimum temperature in winter in deg Celsius}
#' }
