Spotlight on Climate: Climate change, wildflowers and pollinators

Spotlight Logo

In 1973 several of us, who were graduate students or friends at the Rocky Mountain Biological Laboratory (RMBL) in Gothic, CO, decided to collaborate on a study of wildflowers. We had been studying bumble bee and hummingbird pollinators and realized that to understand them we needed to understand the changing variety and abundance of their wildflower food sources across the flowering season.

We started carefully counting wildflowers in several different habitats, and 52 years and 6-7 million counted flowers later, we know we have 130 different species, we know when each species comes into bloom (flowering phenology), how long they flower, and how many flowers they make.
