ylläpitokarsintaa

Ylläpitokarsintaa refers to a silvicultural practice in Finnish forestry that involves the selective removal of trees within a stand. The primary goals of ylläpitokarsintaa are to improve the growth of the remaining trees, enhance timber quality, and maintain the health and vitality of the forest. This process is typically carried out in young or middle-aged stands before they reach their full economic potential.

The selection of trees for removal in ylläpitokarsintaa is based on several criteria. Dominant trees that are healthy and have good potential for future growth are usually left standing. Conversely, suppressed trees, those with defects such as poor form, disease, or damage, and overcrowded trees are often targeted for removal. This selective thinning helps to reduce competition for resources like light, water, and nutrients, allowing the favored trees to grow larger and faster.

Ylläpitokarsintaa can also contribute to the ecological objectives of forest management. By removing diseased or damaged trees, the spread of pests and pathogens can be limited, improving overall forest health. The removal of some trees can also increase light penetration to the forest floor, promoting the growth of understory vegetation and enhancing biodiversity. The timing and intensity of ylläpitokarsintaa are carefully planned to balance economic benefits with ecological considerations, ensuring the long-term sustainability of the forest.
