Croxley Common Moor covers 41.9 hectares and has been designated as a Site of Special Scientific Interest as well as a Local Nature Reserve due to the special plantlife and community value.
The moor has over 250 different types of plants in addition to numerous ant hills made by yellow meadow ants and form a series of mounds across the Local Nature Reserve.
These ants make a tasty meal for green woodpeckers which can often be heard 'yaffling' in the background.
During the winter volunteers remove unwanted vegetation that would otherwise turn the open moor into woodland and from around July each year they are helped by a number of cows which lazily graze the moor.

Volunteer Days at Croxley Common Moor
Croxley Common Moor is one of the best sites for wildlife in the country, in particular its wildflowers. To help keep it this way we need your help.
Join the Friends of Croxley Common Moor on the second Sunday of each month at 10am to lend a helping hand. Everyone is welcome and no experience is necessary.
Oxhey Woods Local Nature Reserve is 97.7 hectares of principally, ancient semi-natural woodland in South Oxhey, several areas of which date back towards the last ice age some 10,000 years ago.
The woods contain a range of habitats which make it one of the most important woodlands in the county. Within its bounds can be found spring displays of bluebells, anemones and violets plus the unusual wild service tree.

Volunteer Days at Oxhey Woods
The Oxhey Woods Conservation Volunteers work with the Council and the Countryside Management Service to help keep Oxhey Woods special.
The Oxhey Woods Conservation Volunteers hold regular volunteer days and everyone is welcome to lend a helping hand.
Prestwick Road Meadows Local Nature Reserve is a remnant of old farm meadows in South Oxhey. The ancient hedgerows that separated the fields can still be seen today.
More than 97% of flower rich hay meadows and pastures have been lost since the 1940s and this is one of the few meadows that has survived untouched.
Summer is the best time to see Prestwick Road Meadow in flower, although the seasonal pond can be a hive of activity with tadpoles, frogs, herons, butterflies and dragonflies.

The Withey Beds Local Nature Reserve is 7.7 hectares of one of a few remaining wetlands in Hertfordshire.
This is only the second site in the country to be purchased using a Compulsory Purchase Order based on its wildlife value alone. It is particularly important as it supports a wide range of habitats including wet woodland, marsh, drier grassland and open ditches as well as the River Colne.
Several projects have taken place since 2003 including converting an abandoned WWII pill box into a bat roost, making a living willow hide and installing a barn owl box.
A spider, which has not been reported in Hertfordshire since 1880, has been recorded at The Withey Beds. TRDC has received two prestigious Green Apple Awards for the environmental work that has taken place at The Withey Beds.
