woodland exploitation again increased during the napoleonic era in the early 19th century, probably because of the high prices that oak was commanding at this time. replanting and management of the oak forests was promoted at this time. there was a large-scale felling of oak trees at ross island in 1803, glena in around 1804 and tomies in 1805. tomies was then replanted with three-year-old oak and glena was coppiced. these activities have increased the relative abundance of oak in the park in the past 200 years. as most of the oak trees in the woods today are around 200 years old, it is likely that the majority of them were planted, and the oakwoods that have never been disturbed by humans are restricted to a few isolated pockets in remote areas such as mountain valleys.
