Butterfly update...

Part of my job as seasonal ranger is to monitor butterflies on the reserve. This is done by carrying out weekly transects. This involves walking a set route around the reserve covering many different habitat types and counting the number of different species encountered. Transects can only be carried out when strict criteria such as minimum temperature and wind speed are met.
Carrying out butterfly transects allow us to monitor butterflies on a local level as well as to contribute nationally. At the end of the year our records are submitted to Butterfly Conservation and though them our records feed into a larger dataset helping to build up a picture of how species are doing nationally. Analyzing the data allows us to see things such as population declines, increases and distribution trends within individual species.

So far this year’s records are indicating that it has generally been a quiet start for many species on the reserve. Cold and wet weather is thought to be the reason for this.

To find out how this year’s weather has affected butterflies nationally visit the Butterfly Conservation website and read this great article.

Fingers crossed that the weather will be nice for our Moth and Butterfly morning on Sunday the 1st July... further information below.
