In Rāzna National Park, Dainis Tučs, a nature conservation specialist, emphasized the importance of light in fostering life within the forest ecosystem. He pointed out that the coniferous forest, primarily composed of spruce, is monotonous and has suffered from neglect, leading to the encroachment of broadleaf trees that block sunlight, thereby stifling the forest floor's growth. This underbrush issue creates a rather lifeless environment devoid of diverse plant species.

Contrary to traditional logging motivations, which typically focus on wood extraction, the current efforts in the park are dedicated to cultivating a healthier and more biologically varied forest. Tučs noted the presence of beautiful oak trees and giant trees that could thrive over hundreds of years, demonstrating the potential for a future forest rich in diversity. The work conducted covers a 14-hectare area adjacent to valuable habitats, aimed at allowing rare species to gradually establish themselves in the rehabilitated forests.

This initiative prioritizes removing trees that overshadow and inhibit the growth of the forest floor, specifically targeting spruce and other obstructive species. Only oaks are retained in the understorey to allow light to penetrate. Tučs explained that this careful thinning will eventually lead to a more vibrant ecosystem, as the removed branches will decompose and enrich the soil. The meticulous management near existing biotopes further ensures that essential mosses and lichens can thrive, supporting a diverse range of flora and fauna in this rejuvenated habitat.
