Any time of year is a good time to go to the Dorset Wildlife Trust Reserve at Kilwood; there is always lots of interest to see. The very best time, however, is the last week in April or the first week in May when the woodland floor is the most amazing sight. There are acres of ramsons (or wild garlic) that make the most wonderful white carpet. almost like snow, and I have to say that it is one of the most memorable floral sights I have ever seen, even outstripping bluebell woods.
Up until a hundred years or so ago this area was subject to extensive clay extraction but nature has reclaimed and recolonised the remnants of the industrial past. There is now lots of natural interest, especially around the deserted clay pits which now form wildlife ponds. The spoil heaps too are rich in species. Expect the unexpected at Kilwood!
The recovered clay working is only part of the story of Kilwood. To get to the main woodland where the ramsons and bluebells are you atrt with a walk down a country lan e with hedgerow on either side. You then pass the clay workings and come to rough pasture where the working horses once ate their lunch (and tea, supper, breakfast, etc!). Pressing on you come to hazel coppice and damp woodland before the reward, the oak and beech woodland where the ramsons can vbe found in spring.
One small word of warning. As the soil is clay it can get very wet and muddy so even in summer make sure you start out with sturdy, waterproof footwear.
