  1. Atlas recording is just the start Steve Cham Future challenges for Dragonfly recording

  2. “Practical challenges in the use of biodiversity data” “From records to research” “using distribution data” “Translating volunteer recording in to …conservation action”

  3. Dragonflies in Focus – DiF objectives • To develop a sustainable system for gathering, managing and using information about the status of dragonflies in the UK • To provide access to authoritative and reliable information on dragonflies, in particular through the National Biodiversity Network (NBN) • To put dragonflies more securely ‘on the map’ in the UK, through increased awareness and involvement of the British Dragonfly Society’s membership and of the broader public • To publish a new revised Atlas of UK Dragonflies (which can be used as a focal point for the above developments)

  4. DiF objectives to be achieved by:- • Developing the recording and monitoring programme • Improving the scope and quality of records • Developing, in partnership with local organisations, a national system for collating and managing dragonfly records • Increasing participation by volunteers in a range of surveillance activities • Sharing information with other organisations via the NBN Gateway • Producing clear end-products, within a realistic time scale

  5. Atlas recording is just the start ? 1,089,126 records >98%submitted by volunteer recorders Record cleaner used to verify records coming in to DRN 1996 2014 2030? Index of change !

  7. Progression of recorder effort throughout the new atlas period based on Vice County Diversity Threshold (VCDT)

  8. The County atlas effect Bedfordshire Northamptonshire Surrey Atlas projects motivate and mobilise recorders!

  9. The ‘special project’ effect All VC11/12 Damselfly records Less Southern Damselfly Less Scarce Blue-tailed Damselfly Less ‘The Dells’ records

  10. “There are known knowns, there are things we know that we know. There are known unknowns, that is to say there are things that we now know we don’t know. But there are also unknown unknowns – they are things we don’t know”Donald Rumsfeld “There are things we now think we know but don’t yet know how to interpret them” Steve Cham

  11. Colonising species - mapping the spread

  12. Changes in phenology

  13. Interpretation of distribution data

  14. Accessibility 2-3 hours walking to get to sites. New records from wind farm surveys. ‘Remote’ species

  15. Index of change -data analysis Method A Decline Stable Increase Method B Decline Stable Increase • Frescalo • Mixed model • % recorded 10km • BDS ‘gut’ feel

  23. Challenges with recorders • Variable consistency of recorders - ID skills e.g. Common Hawker • Record cleaner worked well at highlighting the issues • Weather impacts on recording, especially in upland areas • partial lists vs complete lists impact on data analysis • Focussed recording eg RDP failed / Monitoring • ‘Twitchers’ target rare or new species that can lead to bias in data • Recording remote areas, especially in Scotland

  24. What can we implement for the next atlas in 2030!!! Overcoming the ‘new’ challenges • Need a more robust method for analysing change • Making records available / better recording of negative records • Ensuring funding for a data manager • Adapting to change in recording tools / Getting recorders to use new technology e.g. online recording / New apps • Need to train/ guide recorders -more and more demands on the volunteer effort. • There is a place for ad Hoc recording and we have to find a way to maximise it

  25. A great thanks to : • Steve Prentice for providing maps, charts and general support • Colleagues in the DCG and Atlas editorialteam, Brian Nelson, Dave Smallshire and Pam Taylor • Friends at BRC- Helen Roy, David Roy, and Nick Isaacs for support and discussion on data analysis • NBN Trust for support and encouragement from the start • And to all the recorders, wherever they are!
