Did you know springs support more than 20% of the endangered species in the United States?
Despite being small areas compared to lakes or oceans, springs are really diverse! However, springs are also one of the most threatened ecosystems: the Springs Stewardship Institute reports that a lack of information and attention to springs has resulted in over 90% of springs lost in some areas.
Earlier this year, Kathryn Wertz’s 6th graders at Sinagua Middle School, Kesava’s 4-6th graders at Haven Montessori, and the Centennial Forest Outdoor Leadership Academy with Manager Cheryl Miller got the chance to contribute to springs research. Students traveled to different springs, defined as emerging groundwater, and measured water quality, water flow, identified plants and animals, and collected information on the source and extent of the spring. Afterwards, they discussed why springs might be threatened: human water use, livestock grazing, mining, or pollution are just some of the threats to our springs. “Use less water!” “Practice leave no trace principles!” and “stay on the trail!” rang out when prompted for suggestions on how we could become stewards of the springs.
These data collected help support a large forest restoration project in northern Arizona. The Four Forest Restoration Initiative is a collaborative effort across 2.4 million acres, to bring natural fire regimes, plant and animal diversity, and healthy forests back to the area. The project focuses on thinning small diameter trees, small prescribed fires, and also protecting water in the forests.
Springs are critical water sources for the diversity of animals that call forests home, and also for a variety of plant life. When forests become overcrowded (a healthy acre of forest should have about 30 trees or less, whereas now we might see 300 trees/acre), all those trees send deep roots down to suck up the available water. By thinning some of the trees, we will hopefully raise the water table, and provide access to surface water for the other species. The trees that are left to grow also have more space, more nutrients, and an easier time staying strong and healthy. A win-win for everyone!
Not only did these students collect important information that will be useful for forest management, but they also proved to be capable and enthusiastic citizen scientists! We can’t wait to do it again! Thank you to Joseph Holway from the Spring Stewardship Institute, Cheryl Miller from Centennial Forest, and Grand Canyon Trust for helping make this project a success. Thank you also to Arizona Game and Fish Department and the Heritage Fund for providing financial support to help get students outside doing real life STEM!
Teachers can apply for field trip funding through the Arizona Game and Fish Heritage Grant program. Link to the Heritage Grant site above and/or download the pdf here! The grant proposal is due by October 31, 2017.
