History of the site
Under conditions of climate change restocking is likely to become increasingly challenging and require more intensive silvicultural care. This experiment examines the impact of microclimate on growth and survival of planted Douglas fir trees. Seedlings have been planted on open clearfell sites and under an irregular shelterwood to identify relationships between microclimate conditions and growth and survival of seedlings. The forested compartment comprises of Douglas fir planted in 1927 as an even-aged stand and now managed as a seed stand. The stand was thinned in 2011. There is some natural regeneration of Douglas fir, and the ground vegetation comprised of grasses and mosses. The nearby open restocking area was cleared of dense natural regeneration in 2001 and is now managed as a plantation on ancient woodland site (PAWS). The site was unvegetated and had a large amount of harvesting residue.
