Have your heard of BioBlitzes, but never joined one? Have you wanted to get involved in citizen science, but haven't had the time? Well, here's your chance! This year, the Crown of the Continent Research Learning Center (CCRLC) is hosting two events—the Noxious Weed Blitz and the Nocturnal Pollinator BioBlitz.

Loosely defined, a BioBlitz is an event where public participants and scientists work together to document the biodiversity of a specific location.

The Noxious Weed Blitz, provides valuable education to visitors and helps Glacier National Park reduce weed populations along park trails. Our citizen science program will spend the day working with biologists to learn about the identification and ecological impacts of noxious weeds and help in their removal.

The Nocturnal Pollinator BioBlitz will help to close a critical knowledge gap in Glacier regarding the diversity and vulnerability of our nocturnal pollinators (i.e. moths, nocturnal bees, flies). These fascinating creatures are critical to the success of many of our rare plants and provide a major, fat-rich food source for some of our most beloved species (e.g. the grizzly bear). Come join us in discovering, identifying, and cataloging the rich variety of species that call our Dark Sky Park home.

After lunch, staff and volunteers head out to "weed infested" areas to pull noxious weeds.

There are roughly 40 species of known moths in Glacier. The Rocky Mountain Clearwing Moth is just one of many you might encounter during the Nocturnal Pollinator event!
