The first aim of the Great Fen is:
To create a new, resilient, fenland landscape which delivers major wildlife benefits and achieves high standards of sustainability.
In order to ensure that the project is actually delivering these benefits for wildlife it is essential to monitor what is there now and to record new species as they arrive. The purpose of monitoring is to:
This involves answering some of the following questions.
How far these questions can be answered varies from species to species, and a range of techniques and equipment needs to be used. For example, for many species of birds it is possible to answer the first four questions by walking across the project area in the early morning once a month and counting which birds are seen or heard - and you need a team of birdwatchers using binoculars. However, Water Voles are rarely seen but their presence can be inferred by looking for signs such as their droppings and burrows, so you need a team of trained volunteers to survey a sample of wet areas and ditches, sometimes wading and sometimes working from the bank or a boat. For species of deer, cameras can be used (see Chinese Water Deer), for bats you need bat detectors, while some groups of species can only be identified using a microscope (see, for example, Bryophytes).
The wardens of the two National Nature Reserves (NNRs), Woodwalton Fen and Holme Fen, have been monitoring wildlife for many years, but it has been particularly important to extend the monitoring programme as the new parts of the Great Fen area come into restoration.
The following list of monitoring that is carried out by staff and volunteers on the Great Fen. If you would like to find out more about becoming a monitoring volunteer for future surveys, please contact Henry Stanier, the Great Monitoirng and Research Officer.
