During selective cutting, leave pollen-producing plants to grow

Habitat	Function	Type of work
Forest	Living environment	Pre-commercial thinning

In order to maintain biodiversity and ensure ecological coherence, forest management shall maintain the structural elements of habitats (e.g. trees from the previous felling period, old-growth trees and stumps, flatwoods, hardwoods, hollow trees, trees with burn marks, shrub species and species of trees that are not very common in the forest), also taking into account their potential impact on forest health, timber quality, ecosystem condition and human safety.

Description of the action

In younger forests, leave nectar- and pollen-producing trees, shrubs, and herbaceous plants (especially fireweed and raspberry) to grow on old extraction roads and open edges of clear-cut areas, where they will also be able to form flowers in the future. Leave them in an extent that does not hinder the growth of the target tree species.

Why?

Nectar- and pollen-producing herbaceous plants, trees, and shrubs bloom and bear berries, providing food for insects, birds, and mammals. In the first few years, forest renewal maintenance should be done in corridors (about 1 meter wide) to allow many flowering plants to remain. Growing plants also provide shade and moisture for target trees.
