A couple of weeks ago I wrote about a National Trust 'Uncovered' weekend at Sheringham Park in Norfolk. They have two more coming up at different locations, which sound like they're very worth attending if you're anywhere nearby.

In their own words:

• At the Wimpole Estate near Cambridge – on 5-6 October – we'll be holding a weekend to help visitors discover how the farming of our land for food has over time shaped the landscape. Farming and nature are obviously very closely related, and walks/talks during the weekend will cover lots of wildlife-friendly traditional farming practices, like hedge-laying and organic soil management.
  See the full programme for events that weekend.

• At Northey Island in Essex – on 12-13 October – visitors will have the opportunity to discover how the influence of man and the forces of nature are changing the coastline and seascape. Amongst other activities, there will be a 'saltmarsh safari' (where you can find out what’s so special about this rare habitat and the wildlife that depends on it) and lectures on how climate change is affecting the coast.
