The Fondation québécoise pour la protection du patrimoine naturel is surveying bats in Portneuf, Quebec, to protect five threatened species [1].

This effort is critical because bat populations are facing an existential threat from white-nose syndrome. The disease has already killed more than five million bats [1], disrupting local ecosystems and threatening the survival of several species.

Researchers are utilizing ultrasonic devices to track and census the animals. Because bats communicate and navigate using high-frequency sounds beyond human hearing, these specialized tools allow biologists to identify which species are present in the region without disturbing the animals. The data collected helps the foundation identify critical habitats that require formal protection.

Field activities for this census occurred during the summer of 2025 [2]. These efforts build upon a longer history of regional study, as young biologists began conducting observations in the area in 2019 [3].

By mapping the current distribution of the five targeted species [1], the organization aims to create a conservation framework that can mitigate further losses. The focus remains on identifying the most vulnerable colonies to ensure that protection measures are applied where they are most needed, specifically in the Portneuf region.

White-nose syndrome continues to be a primary driver of population decline. The fungal infection affects bats during hibernation, causing them to wake up prematurely and exhaust their energy reserves. With millions of deaths already recorded [1], the census serves as a vital baseline for recovery efforts.

“The disease has already killed more than five million bats”

The use of ultrasonic technology in Portneuf represents a shift toward non-invasive monitoring to protect biodiversity. By quantifying the impact of white-nose syndrome and identifying the specific locations of the five threatened species, the FQPPN is moving from general observation to targeted habitat preservation, which is essential for preventing local extinctions of these mammals.
