Morden Bog was featured on the BBC Springwatch programme in 2010; it is where Simon King was using fantastic slow motion photography to film a hobby catching dragonflies.
Morden Bog is exactly what it says on the label - a bog. Much of the area is really not suitable for casual walkers and much of the wildlife interest lies within the bog. However, there is lots outside the bog to interest the amateur naturalist and is well worth a visit, especially in summer. However, in winter some unusual birds frequently turn up, great grey shrike, for example.
The site is designated as a National Nature Reserve and with good reason! In the boggy areas are several very scarce plants including marsh clubmoss and it has an outstanding selection of insects including bog bush-cricket and several species of dragonfly and damselfly.
Bleak in winter, a picture in late summer; but well worth a visit any time.
