Monks Wood Nature Reserve


A visit to Monks Wood Nature Reserve will take you to the largest piece of ancient woodland in Cambridgeshire. In fact, it is so big that it is easy to get lost, especially if you venture off the main pathways, known as "rides" which criss-cross the wood. Ask me how I know. 

We rarely meet anyone else in the wood, perhaps because of the limited parking available nearby, or maybe because it is not very well known even though it has been here hundreds of years.

Given its age, it is surprising that Monks Wood didn't receive its National Nature Reserve status until 1953.  Ten years later, scientists built a research station beside the wood to study the flora and fauna of the area. Back then you had to have a permit to enter the wood, and these were in short supply. Although a permit is no longer required, many people don’t realise this.

So, what is in store for you in the woods? 

There is room for the kids to let off steam along the meandering mown "mazes" of the wider rides. These serpentine routes have a purpose and are not created by drunken mower drivers! They allow ground cover plants to grow at different rates. If you return after the next cutting, you will find the maze has changed.

Leave the main rides and take the narrow, wilder pathways to discover ponds (there were 16 back in 1973, but many dried up) and a multitude of wildlife. 

Wildlife in Monks Wood Nature Reserve

Beetles, butterflies, and other bugs

The reserve is famous for being one of the top sites for beetles in the UK, with over 1000 species recorded. These include...

  • the rhinoceros beetle, complete with a single horn on its head
  • yellow and black longhorns who can grow up to 20mm long
  • various ground beetles that don't even have common names 
  • I also mustn't forget the ladybird, as they are also beetles.

Watch out for caterpillars, moths or butterflies depending on when you visit. The butterflies you could find include marbled white, speckled wood, white admiral, silver washed fritillary, purple hairstreak, black hairstreak, common blue, brown argus and brimstone.

A close inspection of the plants and trees in the wood may reveal shield bugs, with their intricate colours and patterns, some looking like little jewelled scarabs. My identification skills are not good enough to name them all. 

I am more knowledgeable about dragonflies, and have been lucky enough to see broad bodied, scarce and four spotted chasers at Monks Wood Nature Reserve and look forward to finding others on our next visit.

Then of course there are the oak bush crickets, dark bush cricket, speckled bush cricket .... I could go on ... but you get the idea.

Other curious bugs include...

  • the yellow and black scorpion fly with a tail that looks like a sting and a long “beak”
  • the long-necked snakefly, considered living fossils by some 
  • and the harmless crab spider whose front legs resemble a crab's claws

I find it fun to photograph creatures that are new to me, so I can attempt to identify them later. Research into the critter in the photo below that skittered across the path in front of my feet revealed that it was a glow worm larvae, for example. 

This place really is an Aladdin's cave for the entomologist!

Reptiles and amphibians 

Besides bugs, you might come across reptiles and amphibians such as frogs, great crested newts, grass snakes and lizards.

You can find the creatures above in rotten wood piles, left specifically to provide them with homes, on the trunks of trees or even under loose bark, in and around the ponds and just walking around on the ground. Keep your eyes peeled.


If you prefer to look up, instead of at the ground, there is also plenty of bird life in the bushes and trees. You might hear them before you see them, especially when the trees are in leaf.

In the spring, if you are extremely lucky, a nightingale might serenade you. But more common birds that could be in residence at various times of year include the green and great spotted woodpeckers, whitethroat, lesser whitethroat, goldcrest, chaffinch, jay, treecreeper, and bullfinch.

Redwing and fieldfare are regular winter visitors, and you might even see a brambling with them.


Muntjac deer

During your walk, you might also encounter a muntjac. These deer are about the size of a large dog, standing at about half a meter tall. They are a non-native species, and can cause damage to trees and plants, so many people consider them a pest. For this reason, certain areas of the wood have deer fencing in place to keep them out. 

You might also see brown hares, rabbits and foxes in the fields and clearings. 

Wildflowers found at Monks Wood Nature Reserve

One reason for visiting the woods in spring is to enjoy the glorious carpet of bluebells. Before the deer fencing arrived, the bluebells were in danger of disappearing, but they hung on and seem to be making a comeback.

Look out for primroses and wood anemone in the spring. 

As the year moves into summer, wild orchids show up around the wood. The scientists catalogued various types until 2003, but I am not aware of a survey being done since then. I saw a photo of a lovely greater butterfly orchid taken in 2017.

Another eye-catching bloom in June, if you are lucky enough to locate it, is grass vetchling with its crimson flowers. 

Have you planned your visit yet?

I dithered with making a page about Monks Wood Nature Reserve. It is so peaceful and interesting that in a way I want to keep it to myself! But a good thing is best when shared, eh? If you pop along, don't forget to comment below to let us know what goodies you found in the woods.
