A hidden wildlife gem nestling in the Chilterns hills, rich in wildlife that will lift your spirits whatever the season.
From April 10th to 21st there will be a road closure at Bix. Road access during this period will be from Middle Assendon only.
High up in the Chiltern hills, Warburg Nature Reserve is a remote and magnificent place, rich in exciting plants and animals all through the year.
The flower-rich grasslands in the valley bottom give way to extensive woodlands rising up the valley sides. It is the richest BBOWT site in the three counties for orchids. From April right through to August orchids can be found in all of the habitats, including fly orchid and bird's-nest orchid. Warburg Nature Reserve even has its own microclimate with exceptionally cold temperatures on winter nights.
The reserve is home to an incredible range of habitats sheltering thousands of species, and each season there is something interesting to experience.
This is my favourite wild place to come for a walk - you can't match it.
In spring, the woodland is awash with spectacular bluebells and wood anemones.
In May and June the reserve has a dawn chorus second to none. The wide sunny rides and open glades of chalk grassland are full of summer flowers, including pyramidal orchid and swathes of aromatic wild marjoram and thyme. These are followed by autumn and Chiltern gentians and glorious colours throughout the tree canopy, while down below, an incredible 900 species of fungi grow. In winter, you can enjoy magical frost along the valley bottom.
Oddities and rarities
In July you can see the yellow bird's-nest, a strange leafless plant that grows in some of the darkest parts of the beech wood. Warburg Nature Reserve is also wonderful for rare butterflies. Oaks provide food for purple hairstreak caterpillars, while the silver-washed fritillary lays its eggs in bark crevices above violets on the ground below.
Nature Detectives Trail
It's free, it's fun and it's great for all the family!
From the Interpretation Centre families can pick up a special backpack that includes games, trail notes and spotter sheets for wildlife as tiny as beetles and as big as red kites. Children can follow the trail through the woods, the wildlife pond and the grassy glades at their own pace.
Sustainable charcoal is now available to buy at Warburg Nature Reserve.
