The quadrat data were analysed using statistical methods such as TWINSPAN Hill and sorted into distinct communities and sub-communities based on species composition. Environmental data collected e. The aim was to provide comprehensive coverage of the country England, Scotland and Wales and later the methods were extended to Northern Ireland Cooper et al.
The aim was also not just to focus on rare or interesting vegetation types but to include nearly all natural, semi-natural and artificial habitats excluding only short-terms grassland arable leys. To gain support from a wide range of academics and practitioners it was also important that the final classification should be more than a list of communities for mapping and inventory.

It was important for the classification to help understand how vegetation works and how particular communities are related to climate, soil and management factors and how they change from place to place zonation and how they change through time successional dynamics. The structure of each volume is similar starting with a general introduction to the NVC and with keys to help determine vegetation types from your own quadrat data and then the main part of each volume is a set of community accounts.
Each community account is written with the same format, so once you get used to using the NVC you know exactly where to look for different bits of information:. The objective here is to delimit vegetation areas stands which are relatively uniform in species composition and structure.

It is not quite as esoteric and mysterious as it sounds but it does take good visual skills and practice and experience to achieve. Spend time walking the site to get a feel for the whole range of variation in the vegetation and then delimit areas which seem to be related in terms of species and structure. If in doubt sub-divide areas. The surveyor chooses ideally a minimum of 5 quadrats from each homogenous stand, the selection is subjective i.

Boundaries are where one vegetation type stops and another starts. NVC sampling needs to avoid boundaries where possible because these will not conform to NVC types by definition. In some sites, e.
In other cases there may be more than one community and the boundaries are obvious e. In other cases there may be more than one community but the boundaries between them may be much more diffuse with one type passing almost imperceptibly into another. In these cases it is necessary first to identify one more or less homogenous vegetation type and then to walk first in one direction and then another direction and work out how and where the changes between types occur.
The job then is to sample just the homogenous areas of the main vegetation types and avoid the diffuse boundaries.
