The Sierra Club Cross Timbers Group is a newly reformed group of the Sierra Club- the nation's oldest conservation group- that will serve residents of Denton and Collin counties. We hold monthly meetings and are planning hiking day trips, speaking engagements from North Texas conservation experts and sustainable businesses, and clean-up events at area lakes, parks, and roadways. Please visit us at our next meeting and learn how you can help preserve the natural world around you in your own community.
