Botanical project in Belhus Woods Country Park___________________ Mrs Mary Smith 33 Gaynes Park Road, Upminster, Essex RM14 2HJ Tel: 01708 228921 Belhus Woods Country Park is a substantial area of land (about 250 acres, or 100 hectares) owned jointly by Essex and Thurrock Councils and managed by Essex and forms part of the Thames Chase Community Forest. It lies just North of Aveley on the Thames flood plain, so the soil is based on various young alluvial deposits including sand and gravel. Most of the Park was in the old Belhus estate, with large gardens laid out by Capability Brown as a young man, but not much of that remains. The M25 cuts across it now, and only the part West of the motorway is in the present Park. Some of the woodland is over 200 years old, and is rich in plant, fungal and invertebrate species. Much of Warwick Wood (a detached part of the Park, West of Aveley Road) is ancient woodland and its insect life has been the subject of an interesting article in a recent issue of this magazine. Recently, lakes have been made from sand and gravel pits, and large areas of grassland have been added from arable farmland; the Park is still growing as further areas of gravel extraction are being landscaped ready for recreational use. Some woodland is left alone with minimal management (removal of invading Sycamores), while another section is coppiced 15 Essex Field Club Newsletter No. 33, September 2000
