The Glen is in the heart of Cumbernauld.
It is the most valuable are of woodland in this area and provides much needed breathing space for the townspeople. .Split into two areas,Cumbernauld Glen and Vault Glen are both abundaant in native flora and fauna. Used extensively as a place to relax and enjoy the peace and quiet.

Land Management
The 15ha site consists mainly of woodlansds of the Flemings and Burns Estate,
plantations of both conifer and mixed woodland which were planted by the Developement Corporation in the 1960's.
This recent planting was undertaken on land previously used for agriculture.Oats ,Barley and Potatoes were grown here,as well as sheep and cattle grazing.
There are also areas of scrub and grassland in the Glen.The Red Burn and Bog Stank streams run through the site.

The whole of the Glen is now regarded as public open space. In recent years the trust has started the hard work of removing invasive species like Rhododendron and non-native tree regeneration mainly Beech and {Sycamore}.Small areas of Conifer stands have been felled and native trees planted. Much of the formal grassland has been converted into hay meadow.
Nature conservation is the key objective. The trust aims to enhance the biodiversity of the Glen by
encouraging native trees and wildflowers. A slow but worthwhile process.
Flora and Fauna
The ancient woodlands within the Glen are of high wildlife importance. The ground vegetation reflects the age of the site. Vast carpets of wild Hyacinth flower abundantly from May to June. By Summer, Bracken and Broad Buckler fern with large area of Honeysuckle and Bramble to be seen.
Creeping soft grass and wood sorrel are frequent.

Oak and sycamore are the dominant tree species of the glen, with less frequent ash and elm with beech being rare. Rowan and hazel are the most common understorey trees with elder being found closer to the valley floor. Here the wildflowers change with dogs mercury, wood anemone and lesser celandine becoming more common. This is clearly seen around the old limekilns in Vault glen.

Wild angelica, meadowsweet, creeping buttercup and opposite - leaved golden saxifrage are common to the wet flushes found throughout the woods.

Badgers can be seen foraging for food in the glen, Families of roa deer and foxes are also resident in the area. Grey squirrels are now sadly dominant within these woods, with the last sighting of a red squirrel being in 1982.

Many small mammals live in the undergrowth, such as field voles, wood mouse, pygmy and common shrews.

A special feature of the glen is the high density of breeding birds, Green woodpeckers, siskins, jays, blackcaps and garden warblers are a common sight.

The jays are significant for their role in the regeneration of oak trees. Green woodpeckers and wood warblers
{both very scarce locally} also breed in the glen. Grey wagtails and dippers can be seen by the red burn.

Past Times

The glen is awash with historical references.The remains of Red Comyns castle,13th

century,can be found next to the parkland. It was burnt down by Robert the Bruce in 1297.

The land was then gifted to the Flemings who were allies of Bruce.

They built themselves a castle on the site were Cumbernauld House now stands. A 16th century dovecote stands next to the main path in the glen.

Least, not forgetting that the ancient woodland and surrounding land was used by King James V as a royal hunting ground. So for an enjoyable walk, come to cumber auld glen and let history come alive.
