Ancient trees

Cassiobury Park has a large number of mature and veteran trees, including a Cedar of Lebanon, which is over 100 years old, and several veteran Oaks. We will be launching our free printable tree trail map in the near future.


About half of Cassiobury Park is wooded (the wooded area is also known as Whippendell woods).

Managing the park for wildlife

When trees die or branches fall we leave the wood in place if safe to do so, as it provides excellent homes for wildlife.

Wild flower meadow

Several areas of Cassiobury Park are left to grow as meadows during the summer and part of the community garden area was reseeded with a special wildflower mix in 2015.

Local nature reserve (LNR)

The area next to the river Gade has been designated as an LNR due to its value as a home for wildlife.

The area is maintained by volunteers from the Friends of Cassiobury Park, the Herts and Middlesex Wildlife Trust and TCV Green Gym.

Watch Lesley Davies, Chief Executive of the Trust, talk about our LNR:

Site of Special Scientific Interest (SSSI)

The Whippendell woods is a SSSI due to the fact it has never been continuously wooded for hundreds of years and contains rare species of plants and fungi.

The River Gade runs through Cassiobury Park

It is full of aquatic life including fish.
