SmartRiver Survey
We have now collected samples from the river Chess and the River Hamble. We should receive the results of the survey in the next few weeks and that will tell us more about riverfly species and diversity in these two chalk streams.
Stay tuned!

Extended Riverfly on the Chess.
By comparing data before and after restoration, the monitoring helps understand how well the stream is doing. Extended riverfly provides more detailed data by monitoring 33 species.
We are running a free training day on the 14th October: https://bit.ly/45cXSN8

Autumn is here!
Today the sun is perpendicular to the equator, and daytime and night time are of approximately equal duration.
Autumn is often celebrated with festivals, music, dancing, and communal gatherings.
Look around you, do you see nature changing colours already...?

Why monitor Water Voles?
🔍Regular surveys help us:
📶Track population health
🔴Spot threats early (like invasive mink)
🍃Improve river habitats
🎯Measure the success of restoration projects
