Lahti police investigate resident for illegal tree felling that may have destroyed flying squirrel habitat

Police in Lahti are investigating a resident suspected of illegally felling trees on city-owned land, potentially severing a protected route used by endangered flying squirrels, Yle reports.

The trees were cut down on a recreational greenbelt between a residential property and a lake, an area designated in zoning plans to remain forested and in its natural state. Authorities believe the clearing was done to improve the property’s lake view.

Häme Police’s criminal inspector Teppo Kallio confirmed the case is being investigated as a suspected nature conservation offense, though charges could later be adjusted to a lesser violation. While the felled trees were directly in front of one residential plot, Kallio declined to name the suspect or confirm whether they are the property owner. He noted the case will likely proceed to prosecution.

A local resident, contacted by Yle, admitted to cutting down “a couple of extra trees” on city land after the 2024 Storm Jari had already toppled some. The resident claimed to have discussed the matter with city officials afterward but said they were unaware of the police investigation and had not been contacted by authorities. Yle has no information linking this individual to the criminal suspicion.

The report to police was filed by the Regional State Administrative Agency (now the Permit and Supervision Authority), with Lahden city officials also questioned. City forester Katja Hattunen stated the municipality had removed a few diseased aspens from the area but not from the site under criminal investigation.

Unauthorized tree felling on city land is a recurring issue in Lahti, often driven by residents seeking better views. Most cases come to light only after neighbors or bystanders file complaints. The city is currently examining a second incident where trees were cut on municipal green space—again apparently to enhance lake visibility—along with cases of deliberate branch cutting and partially felled trees left to fall later, posing safety risks.
