Weald Country Park, just north-west of Brentwood, is an attractive mix of semi-formal parkland with large areas of woodland and the remnants of the 'tree pasture' of a deer park. This is scattered with massive oak and hornbeam pollards, some of which are probably more than 500 years old.
The woodland to the north positively shimmers with bluebells in spring, particularly where conifers have recently been removed. Golden saxifage, an unusual ancient woodland plant, grows in Foxdown Wood, which escaped conifer planting.
Such a variety of habitats attracts a wide variety of birds. Great crested grebes and moorhens breed on the lakes. Nuthatches and woodpeckers are often seen in and around the woods. Flocks of seed-eating birds such as goldfinches and siskins can sometimes be seen feeding on the ground or in the lakeside alders. Little owls can be seen hunting in the early evening.
