Coppice With Standards

Coppice with standards and coppice forests are the result of silvicultural systems widely applied until the mid-twentieth century, mainly for fuel production. Similar to energy plantations in Scandinavia and Germany the above-mentioned systems are characterised by a short rotation. The present paper tries to show that, owing to efficient logging methods, energy wood can be produced from coppice and coppice with standards forests so cheaply that it proves to be highly competitive compared to oil. The economic value of coppice and coppice with standards was calculated on the basis of models and compared to high forest cultivation. Contrary to high forests, the coppice with standards system is cost-covering on poor, well developed and easily accessible sites.

Shoot And Root Biomass

We studied the growth responses of boreal Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies L. Karst.) and silver birch (Betula pendula Roth) seedlings to simulated climate warming of an average of 1.3 °C over the growing season in a controlled field experiment in central Finland. We had six replicate plots for elevated and ambient temperature for each tree species. The warming treatment lasted for the conifers for three growing seasons and for the birch two growing seasons. We measured the height and diameter growth of all the seedlings weekly during the growing season. The shoot and root biomass and their ratios were measured annually in one-third of seedlings harvested from each plot in autumn. After two growing seasons, the height, diameter and shoot biomass were 45%, 19% and 41% larger in silver birch seedlings under the warming treatment, but the root biomass was clearly less affected. After three growing seasons, the height, diameter, shoot and root biomass were under a warming treatment 39, 47, 189 and 113% greater in Scots pine, but the root:shoot ratio 29% lower, respectively. The corresponding responses of Norway spruce to warming were clearly smaller (e.g., shoot biomass 46% higher under a warming treatment). As a comparison, the relative response of height growth in silver birch was after two growing seasons equal to that measured in Scots pine after three growing seasons. Based on our findings, especially silver birch seedlings, but also Scots pine seedlings benefitted from warming, which should be taken into account in forest regeneration in the future.
