History of the site
This site is situated in the Forestry Commission`s National Arboretum at Westonbirt. It is located on two former experimental sites: a larch progeny trial, and a trial of elms established to test for resistance to Dutch elm disease. Both areas were clear felled the year before planting. Because of constraints imposed by the position of existing paths, the new planting is in four fenced areas. A replicated trial testing both REINFFORCE and other species is planted out in a single enclosure on the old elm site, and the REINFFORCE mandatory species are planted on three fenced enclosures on the former larch site. We chose this site because Westonbirt Arboretum attracts 300000 visitors a year, and the new REINFFORCE site is an important opportunity for interpreting messages to both professionals and the general public about the impacts of climate change.
