The 'Fauna, Flora and Geology of the Clyde Area' lists the notable Clyde Area trees at Eglinton in 1901, showing that the estate at the time had one of the foremost collection of significant trees in southern Scotland. Tree removal for sale as timber was one of the first acts of the new owners of the estate when it was sold in the late 1940s, however many had already been removed in 1925 by Neill of Prestwick and Howie of Dunlop, both being timber merchants.
