Skärhållning

Skärhållning is a traditional Swedish farming practice whereby trees are pruned or cut back to maintain a predetermined height, often around 5-7 meters, to prevent shading and promote growth in underlying crops such as hay, oats, and barley. This method has been used for centuries in Sweden to optimize land use and increase agricultural productivity.

Trees used for skärhållning typically include species such as birch, willow, and alder, which are native to the country's boreal forests. The pruning process is usually performed during the winter months when the trees are dormant, allowing farmers to access the areas where the trees are closest to the cultivated fields. Skärhållning is often done by hand, as manually pruning or cutting the trees is more efficient in dense areas.

The primary goal of skärhållning is to create open spaces and allow sunlight to reach the underlying crops, promoting healthy growth and increasing yields. By controlling tree growth, farmers can also prevent the spread of pests and diseases that may affect the agricultural produce. This practice has also been linked to improved soil quality, as the increased sunlight and air circulation promote better nutrient uptake.

Skärhållning is a specific example of silvopastoral systems, which integrate trees into agricultural landscapes to promote ecosystem services and enhance productivity. The practice has become an essential component of sustainable forest management in Sweden, particularly in regions with dense forest cover. Researchers continue to study the benefits and limitations of skärhållning to inform agricultural practices in the region.
