coppice with standards A traditional system of woodland management whereby timber trees are grown above a coppiced woodland. It is used in particular as a method of exploiting oakwoods, in which all the trees except a rather open network of tall, well-formed oaks - the standards at about fifty per hectare - are felled, leaving plenty of space for hazels and other underwood to grow and be coppiced at intervals of ten to fifteen years
