Scientists Pioneer New Monarch Butterfly Habitats on Mexican Volcano

Efforts to establish fir forests at higher elevations aim to counteract climate-induced habitat loss.

Researchers are planting sacred fir seedlings on Nevado de Toluca to create new overwintering sites for monarch butterflies as climate change threatens their current habitats.
The project involves 'assisted migration,' moving fir seeds from the Monarch Butterfly Biosphere Reserve to higher altitudes where future climates are expected to be suitable.
Initial results show that while seedlings face challenges at higher elevations, a significant portion have survived for at least three years, indicating potential long-term viability.
Monarch butterflies have already begun forming colonies in colder areas outside their traditional overwintering sites, suggesting a natural search for new habitats.
Conservationists emphasize that establishing new habitats should complement ongoing efforts to preserve existing butterfly reserves.
