BBOWT's Reserves Surveying Programme -
surveying and monitoring habitats and species on our nature reserves

To manage our nature reserves to their full potential we need to assess the condition of the habitats on site, and have a record of all the species present and how their populations are changing over time.

A rigorous programme of surveying and monitoring was launched in 2002 to standardise BBOWT's approach and collect quantitative data using repeatable methodologies.

The Reserve Survey Programme aims to:

  • Establish species presence/absence, species population trends and assess the condition of habitats
  • Direct the management of reserves by reviewing the success of previous habitat management work and help plan for future management strategies
  • Direct future surveying and monitoring programmes
  • Inspire, train and involve volunteers

At the beginning of each year the Biodiversity Team plans more than 200 surveying projects for the forthcoming spring and summer survey season. Much of this survey work is carried out by a fantastic 'army' of experienced volunteer surveyors. Each surveyor is an expert in the identification of at least one species group.

How to become a BBOWT Volunteer Wildlife Surveyor

The Ecology Team is always on the lookout for new wildlife surveyors. If you are able to confidently identify one or more species groups (e.g. butterflies, dragonflies, birds or plants) and would like to help with the Reserves Surveying Programme, please contact Colin Williams, Ecology Officer (Monitoring), on 01865 775476 or at  colinwilliams@bbowt.org.uk for more information.

Please note the survey allocation period for each year’s survey season is in February and March. By mid-April all of the planned survey work has been allocated and surveyors have begun their survey work. If you miss this deadline, please still get in touch as you can be added to the surveyor list for the following year.

If you are keen to get involved but don’t think your identification skills are quite good enough yet, there may be the opportunity to accompany a BBOWT volunteer surveyor during their survey work. We can also recommend courses you may be interested in attending.

2017/18 wildlife news from our reserves

Hawfinch

The autumn and winter of 2017/18 witnessed the largest national invasion of hawfinches. Not surprisingly several have been seen on BBOWT nature reserves. A rather confiding individual was spotted in the car park at Thatcham Reedbeds during the annual staff and trainee birdrace!

Brown hairstreak egg

In early January 2018 a hardy group of 25 surveyors braved the cold weather to check several hedgerows on the Upper Ray Meadows for brown hairstreak eggs. After four hours of searching the blackthorn in the hedgerows a total of 63 eggs were found. This was more than double the number found on the last check in 2011.

Bittern

Birdwatchers have been flocking to Calvert Jubilee over the winter to enjoy some great birds on offer from the hide. Bitterns and occasionally bearded tits have been performing well in the reedbed below the hide. As a bonus an otter has also been spotted by a fortunate few visitors.

Your wildlife sightings on BBOWT nature reserves

As well as the more formal Reserves Surveying Programme, we are also always keen to receive any ad hoc wildlife records.

If you have wildlife records collected on BBOWT nature reserves that you would like to share with us, please contact data@bbowt.org.uk.

We share biological records with our local record centres, which helps to inform local and national decision-making that may impact on biodiversity and conservation.

Please submit any records that are not from BBOWT nature reserves directly to BMERC if the records were in Buckinghamshire, or to TVERC if the records were in Oxfordshire or Berkshire.

If you've seen some interesting wildlife when you've been out and about, you can let us know via Twitter, including @BBOWT in your tweet.

Water voles, American mink and otter sightings

If you've seen a water vole, American mink or an otter anywhere in Berks, Bucks or Oxon, please email your sighting to watervole@bbowt.org.uk,  including the date and location of the sighting (with a grid reference if possible).
