In forest tree breeding, the genetic makeup of seeds and seedlings used in forest cultivation is improved through plant breeding methods. The goal is to increase tree growth and improve their quality – without forgetting their resistance to climate change and damage. At the Kolmiokuusikko (Triangle Spruce) site, forest tree breeding, gene resource conservation, and the impact of climate change on forest growth are illustrated. Individual sites offer condensed information along with links to various materials, such as videos and English content.

Forest Tree Breeding. Forest tree breeding is a continuous activity where the same measures (selection, testing, and crossbreeding) are repeated from one tree generation to the next. By using genetically improved forest propagation material, forest growth can be enhanced by up to 25 percent. At this site, you can learn more about breeding methods, explore a field experiment, and hear an information brief on vegetative propagation research.

Genetic Diversity. How does genetic diversity help tree species survive in a changing environment? At this site, you can learn about the conservation of forest tree genetic resources through a video.

Climate Change and Forest Growth. The impact of climate change on forest growth is being studied through extensive and long-term experiments. In the provenance experiments located behind the board, the success of spruce trees from different geographical origins in Punkaharju is compared. Some of the tree provenances are under real-time monitoring; you can explore the daily and growing season development of tree growth through the virtual park’s observation station.
