Why it's Wildland
6.9A small reserve with a remarkable range of habitats: ancient woodland, species-rich grassland, scrub and ponds. Its old coppice stools, medieval field ridges and exceptionally rich pond life reward a slower walk.
Castor Hanglands packs a rare amount of ecological and historical detail into less than 90 hectares. Follow the change from ancient woodland to heath and wet ground, and you may find old cultivation ridges, veteran coppice stools and ponds supporting unusually diverse freshwater life.

The experience
Explore a compact mosaic of ancient woodland, grassland, scrub and wetland. Look for surviving ridge-and-furrow earthworks, old coppice stools, seasonal wildflowers and the wildlife associated with its ponds. Expect muddy or uneven paths, particularly after rain.
Things to do
Trace the medieval ridge and furrow
Look across the grassland of Ailsworth Heath for the ridges and furrows left by cultivation about 800 years ago.
Find the old coppice stools
Notice the gnarled bases, rot-holes and fallen limbs of old coppiced trees; these features provide habitat for fungi, mosses, lichens and insects.
Look for spring woodland flowers
Watch the woodland floor for bluebells, primroses, violets, wood anemones and common spotted orchids.
Watch the scrub for black hairstreak butterflies
Black hairstreak butterflies may be seen around blackthorn scrub, with adults sometimes feeding on privet blossom.
Notice the reserve’s ponds and wet ground
Explore the wetland sections and ponds from permitted paths. The ponds support a notable diversity of aquatic plants and invertebrates; do not enter the water.

Quick Escape: woodland, heath and ponds
- 01
Walk from the limited roadside parking to the reserve; allow about 500 metres for this approach.
- 02
Explore the accessible reserve paths, taking in the woodland and open grassland.
- 03
Pause to look for old coppice stools and the remaining medieval ridge-and-furrow pattern.
- 04
Return the same way, allowing extra time if paths are muddy.
Half day · Half day
Make a Half Day of It: follow the habitat changes
- 01
Take a longer walk through the reserve’s woodland, grassland, scrub and wetland rather than turning back after the first section.
- 02
Look for medieval cultivation ridges on Ailsworth Heath and old coppice stools in the woodland.
- 03
In spring, take time to spot woodland flowers; in early summer, look for grassland plants and butterflies.
- 04
Allow for the muddy, uneven paths and return to your starting point.
Verified history
The reserve’s woodland is thought to be more than 1,000 years old, and woodland in Castor is recorded in the Domesday Book of 1087. The western boundary follows King Street, a Roman road connecting Castor and Bourne. Parts of Ailsworth Heath retain ridge-and-furrow marks from cultivation around 800 years ago; cultivation was abandoned about 1350, after which the heath became common grazing land. In 1953, the remaining woodland and heath were declared one of Britain’s first National Nature Reserves.
Hidden details
A pond of exceptional variety — Freshwater Habitats Trust reports that the main pond has had just under 100 aquatic plant species recorded and 134 invertebrate species recorded in one year. Keep to permitted paths and do not assume pond access or entry is allowed.
The old coppice is wildlife habitat — Rot-holes and decaying wood in old coppice stools support fungi, mosses, lichens and insects—look closely without disturbing them.
When to go
March · April · May · June · Check conditions before setting out; the supplied sources do not identify a preferred time of day.
Spring brings woodland flowers, while grassland flowers and butterflies are more evident in warmer months. Black hairstreak butterflies may be seen around blackthorn scrub in June. Paths can be boggy for much of the year.
Paths may be muddy and uneven, and wetland ground can remain waterlogged. Wear suitable footwear and check conditions before visiting. The reserve advises caution in heavy winds because trees or branches may fall.

The story
Ancient woodland, medieval hunting forest, Roman road and medieval ridge-and-furrow cultivation
Best time to go
Spring to early summer for woodland flowers and grassland plants; June for the black hairstreak butterfly. Autumn and winter can be good for fallow deer.
Visit in spring for bluebells, primroses, violets and wood anemones; early summer brings grassland flowers and the chance of black hairstreak butterflies around blackthorn scrub. A calm, dry spell makes the muddy paths easier to manage.
