Presentation Title & Speaker: 'Hedges and hairstreaks - butterfly ecology of the hedgerow' - James Lunt from CPRE Hertfordshire
Time: 19:30 to 20:30
Information James is the CPRE Hedgerow Hero officer for Hertfordshire, with a passion for the countryside. He graduated with a first-class degree in Environmental Biology from the University of Nottingham, where his dissertation focused on hedgerow management. He has worked as a Farm Environment Adviser in Gloucestershire, appeared on BBC Countryfile, and most recently worked at Rothamsted Research. Now a Hedgerow Hero Officer, James is excited to help protect and enhance Hertfordshire's countryside for people and nature.

This talk explores the ecology, history and geography of hedgerows, why they matter, and how good management helps us protect them, optimising their benefit for nature. When properly maintained, they connect wildlife, support farming, build resilience to climate change, store carbon, reduce flooding, and provide vital habitat for butterflies, including species such as the White-letter Hairstreak. Hertfordshire's countryside is shaped by its hedgerows, which reflect centuries of change in the landscape, so join us to learn more about how to value this special feature of the countryside. Details of the project can be found at this link

Presentation Title & Speaker: 'Saving our Insects' - A talk - and a call to action - by Dave Goulson, Professor of Biology at the University of Sussex

Insects are vital, fascinating, weird and wonderful. They are food, pollinators, recyclers, pest controllers, and much more, so we should be deeply concerned that they are in rapid decline.

Dave Goulson will explain the many causes of insect decline, and then turn to the solutions of this crisis. These include fundamentally changing the way we grow food, by rewilding some areas, and by turning our gardens and urban greenspaces into oases for life.

Time: 19:30 to 20:30
Information This is a special joint presentation arranged by the Herts & Middx and Surrey & SW London Branches and will required advance booking through Eventbrite (see below).
