Good news and bad news for the Stort

Winter Programme

 I’ve just had this dismal news crop up.

Please raise awareness where you can and look out for any potential sightings yourself!  This might be on the news too (the last Alert species was).

It’s possible you may have a higher chance to see a hornet as the autumn sets in, as young Queens look for a suitable hibernating and nesting site.

Please see attachments for facts.

The bad news is that the “Killer Shrimp” has been identified in the backwater at Roydon. This is yet another invasive species which outcompetes our native fauna, probably including damselflies! It seems to be travelling upstream and the eggs well be carried on the hulls of narrowboats.
