In 1664 English writer, gardener, and diarist, John Evelyn published Sylva, or a Discourse of Forest-Trees, and the Propagation of Timber in His Majesty's Dominions. . . .To Which is Annexed Pomona, or an Appendix Concerning Fruit-Trees. . .also Kalendarium Hortense; or Gardeners' Almanac. . . .
Sylva was a protest against the destruction of England's forests to fuel her glass factories and iron furnaces. The work was influential in establishing a much-needed program of reforestation in order to provide timber for Britain's burgeoning navy. This program had a lasting effect on the British economy.
Sylva also bears the distinction of being the first official publication of the Royal Society, which had been permitted to publish in 1662. The first edition contained two appendixes, "Pomona" and "Kalendarium Hortense"; the second of these, a gardening calendar, was often reprinted separately, and proved to be Evelyn's most popular work.
