We are currently looking to recruit Volunteer Butterfly Transect Surveyors across our Yorkshire Wildlife Trust Reserves, particularly:

• Wheldrake Ings (North Yorkshire)
• Ashberry (North-east Yorkshire)
• Fen Bog (North-east Yorkshire)
• Askham Bog (North Yorkshire)
• Staveley (North Yorkshire)
• Brae Pasture (North-west Yorkshire)
• Spurn Point (East Yorkshire)
• Sprotbrough Flash (South Yorkshire)

Butterflies have rapid life cycles and often a high sensitivity to environmental conditions, meaning they are uniquely placed to act as indicators to environmental changes. As a result, butterfly surveys are a key ecological monitoring program on Yorkshire Wildlife Trust reserves. Collecting data on the species present, as well as the abundance of these species over time, allows us to identify trends. These trends help to inform us on how best to manage reserves, for example:

•  If data shows a species is in decline; we can investigate what may have caused this and consider what actions might be needed to halt or even reverse it e.g, habitat creation, or changes in management practices.
• If data shows a species is thriving; this may prompt research into why that might be and if there are lessons we can take and apply at other reserves.

Additionally, the data collected through the butterfly surveys is shared with Butterfly Conservation through entry into the UK BMS (United Kingdom Butterfly Monitoring Scheme) database, making an important contribution to a national monitoring initiative. The result of this important work is a knowledge base that, amongst other things, informs government policies addressing environmental issues.

Butterfly surveying is a great way to learn about and enjoy nature, get some exercise, and fill your lungs with fresh air! So, whether a life-long butterfly enthusiast or someone who has only recently come to appreciate their beauty and importance, we would love to hear from you.
