An arboretum area was established in Cedars Park in 2019 in the volunteer Tree Identification Project. These zones are very important in listing tree and memorial data in the park. Visitors have fed back positively, saying that they make it more interesting when deciding where to sit for a picnic.
Zones A, B and C are named after historical features of the grounds.
The woodland walk and wildflower meadows have been omitted, as they are areas of very dense tree population, which makes identification and listing difficult. The arboretum may be expanded in the future to cover the whole park.
Zone A (Deer Park)
From this area westward, there was a deer hunting park at Theobalds Palace, which extended far beyond what is now Cedars Park - it was over 2500 acres in size! King James I built this hunting park in 1607, and Theobalds became his favourite place for hunting.
This area now holds the visitor car park.
The most common trees in this zone are poplars, oaks, maples and ashes.
Zone B (Great Garden)
A section of a large formal area at Theobalds. Sir William Cecil used this garden to host entertainments for Queen Elizabeth I during her visits. It included elaborate flowerbeds, fountains and garden buildings. Bee boles were built into the surrounding walls, and are extant today.
Today, this field is used for picnics, sports and public events.
The most common trees in this zone are hollies, maples and ashes.
Zone C (The Cedars)
A property called The Cedars was built on the grounds in the 1760s. The central building burnt down on 18 September 1913, and today the surviving buildings serve as the cafe, toilets and meeting room. It was also the original name of the park when it opened in 1921, referring to a mature Cedar of Lebanon that stood in the centre of the park.
The most common trees in this zone are maples and limes.
Zone D (Pond Quarter)
Location of the duck pond. It takes up approximately a quarter of the original parkland that was donated in 1919, and is the living 'quarters' of ducks, moorhens and other water birds.
The most common trees in this zone are locusts, yews, hollies, maples and Prunus. There are several very mature London Planes in this area, estimated to be over 400 years old.
