We pride ourselves on being a Society and social interaction at our meetings is an important part of our philosophy.

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.

First the good news, the uncommon White Legged Damselfly has been spotted along the river between Harlow and Sawbridgeworth.

Out and About

BSNHS makes proposal for a Local Nature Reserve along the Bourne Brook in Bishops Stortford. See here for details.

Proposed local Nature Reserve

Installing a nest basket

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.

Woodcock found in the middle of Bishops Stortford

This dead Woodcock was picked up in the Thorley part of Bishops Stortford on 21st November by JR and MR. It has either flown into something or has been predated. Presumably, it is a migrant bird which has come into the UK from Europe on easterly winds. It may well have been attracted to feed on the Thorley green wedge area.
