Site types that use this protocol

Terrestrial

Semi-natural and managed vegetation is often very sensitive to the main drivers of environmental change, ie climate, pollutants and land use practices.

The vegetation protocol is sub-divided as follows:

  • Baseline Survey (VB).  Whole site survey with up to 500 systematic 2m x 2m plots. Species presence related to the National Vegetation Classification (NVC)

  • Coarse-grain sampling (VC).  50 random 2m x 2m grid plots surveyed every nine years.  Species presence recorded in each of the 25 40cm x 40cm cells of the plot. Where plots fall in woodland, seedlings, dbh, height and dominance are recorded within a surrounding 10m x 10m plot (Woodlands (VW)).

  • Fine-grain sampling (VF).  At least 2 10m x 10m plots randomly selected within each NVC type surveyed every three years.  Species presence recorded in 40cm x 40cm cells.

  • In addition:    linear features (VH), permanent grass (VP) and cereals (VA)

For details of these elements of the protocol see the Vegetation (V) protocol document (link above).

Our field activities

SEPTEMBER

This is the last of the busy months in terms of field work at terrestrial sites as the season for monitoring butterflies, frogs, grazing animals and bats draws to an end. In rivers and lakes we sample diatoms for the third time in the year. The usual year-round measurements are also made.
