So thanks to Doug A. for the news that the current Lord Dunsany (the twenty-first baron, great-grandson of the great writer) is 'rewilding' a sizable chunk of Dunsany Castle's extensive grounds. Hence 700 acres of the 1700 acre pasturage is now growing up with trees and native grasses, providing habitat for a wide range of wildlife, from birds to rare Irish bees to badgers. While the baron has banned not just pesticides but also fertilizer and even paths within the Dunsany Natural Preserve, he has allowed a film shoot for a film he has directed, THE GREEN SEA.
The part of the article that interested me most was the bit about his planting trees:
Partly this moved me because if I had land that's what I'd do with it (mimosa, magnolias, and willows), and partly because the time I got to visit Dunsany Castle back in 1987 the road or drive up to the house was lined with beautiful old trees.* When I praised them, Lord Dunsany (Captain Randal, the nineteenth baron), who was driving, commented that they'd been planted two hundred years before, I think it was, and wd be fully grown in about another twenty years. Americans just don't think in those terms.
Here's the link:
P.S.: One minor correction: while Sir Horace Plunkett is as important as they say, and probably more so, he was not an ancestor of the current baron but his great-grandfather's uncle.
*my memory says chestnuts, but I don't think that's possible, unless Irish chectnuts survived the blight that wiped out the American chestnut.
