Pledge Summary

Thornton, Colorado, is a City of approximately 140,000 residents in the north Denver metro area, running south to north paralleling the beautiful Colorado Front Range. Thornton Mayor Jan Kulmann is committed to saving the monarch butterfly and other pollinators with the signing of the Mayors’ Monarch Pledge. She looks forward to continuing her engagement with residents in developing additional pollinator habitat throughout the City. To improve Monarch life cycle success, Mayor Kulmann has encouraged intentional maintenance practices designed for the restoration of pollinator habitat. These practices include reduction of pesticide use near milkweed in targeted locations and the innovative Naturally Thornton program, converting turfgrass into sustainable and native grasslands. In addition, Mayor Kulmann actively supports the citizen driven Monarch Fly Way initiative, which links City appropriate breeding habitat into a single unified habitat corridor, characterized by appropriate maintenance and public education.
