Our ash trees are dying, but don't despair: catastrophes are natural events in the lives of trees
The 17th-century jobbing journalist, whimsical gardener and discreet royalist John Evelyn is most often credited with popularising the idea of trees as property, as status symbols, models of order, heritable goods, investments with a guaranteed growth rate. His book Sylva, or a Discourse of Forest-Trees and the Propagation of Timber in His Majesty’s Dominions (1664) was publicly commissioned in response to a largely imaginary naval wood shortage, but its hidden agenda was to provide a manifesto for a tree-farming bonanza, a wood rush. Evelyn, plucking figures from the air, boasted to the king that his book had been “the sole occasion of furnishing for your almost exhausted dominion with more than two millions of timber trees”, or maybe just one million, he suggested in the second edition. But plantation fever was really ignited in the next century, by German forest science. Forstwissenschaft was steering the growing of timber towards a mathematically precise system, with the trees (increasingly conifers rather than “hearts of oak”) spaced and organised for maximum productivity.
