Site Description
UK ECN site. Alice Holt forest lies in the Weald between the North and South Downs in southern England. Alice Holt Forest Park covers 851 hectares of mainly Corsican pine but approximately 140 ha. of original 1820 oak still remain. The ancient forest is now a truly multi-purpose woodland where research, conservation, timber production and recreation co-exist. The target sampling square is located in 90 hectares of 80 year old semi-natural oak woodland. Gault clay dominates the underlying geology. For the past 25 years intensive monitoring has been carried out under a variety of programs at this highly instrumented site. The site is part of a network of such highly monitored forests across both the UK and Europe. The Alice Holt site is owned by the Forestry Commission and is run by Forest Research under the Integrated forest monitoring programme. Collaboration with other research programs is actively encouraged.
