Hugh Firman, Conservation Officer with the Countryside Service sends this invitation to Naturalists in the Calderdale area:
On Wednesday 19th March at 7pm Jon Dunster from Yorkshire Wildlife Trust will be giving a presentation on invasive plant species. Jon has an in-depth knowledge of species of plants which threaten our native flora.
Jon will also discuss how you can become involved in a project he is heading up, which aims to map the distribution of invasive species in the Calder area.
The venue is The Mereside Cafe at Shibden Park. This is the modern cafe at the bottom car park, not the one at Shibden Hall.
