What have the YES! youth contributed that is sustainable?
In concert with their partners, scientists, and managers, YES! participants transplanted endangered Huachuca water umbel plant into one of the Cieneguita habitat ponds in 2013, and it has already spread to two other Cieneguita ponds—and that’s great news for this plant that looks somewhat like small green spaghetti strands and supports aquatic fish and frogs.
At Cottonwood Tank, a restored pond for Chiracahua leopard frog habitat, over 200 frogs were counted at the last census and signage explains the importance of aquatic habitats and species to stakeholders that visit Las Cienegas.
Participants also expanded the YES! Program to include a Volunteer Day, initiated monitoring and other activities that other youth can do, and through their positive interactions with scientists mentors, have recruited more partnerships to work with youth.

YES! 2016: Sacaton Study Area and Restoration
YES! 2016 was another highly successful year, with 11 high school students participating and two past students participating as interns for the summer. Students spent the summer delving into the management and restoration issues affecting Las Cienegas National Conservation Area (LCNCA). New this year was an introduction to the importance of phenology networks, data collection, and the search for locating an historic orchard at LCNCA.
For the third year in a row, students chose to work at the Gardner Sacaton restoration site. Past summers had implemented different techniques to mitigate soil erosion, planting of salt-tolerant sacaton, and fencing off an area to control grazing affects. This summer, students decided to focus work within the fenced section of the restoration site. Larger salt-tolerant sacaton starts were planted in clusters, both adjacent to existing mature grasses and in open eroded areas to test success rates. Working with Jason Field, University of Arizona soil ecologist, students also transplanted bio-crust from healthy ecosystems into the fenced area. Students systematically designed study plots in order to best determine transplant rates and establishment of healthy crust.
YES! 2015: Sacaton Study Area and Restoration
Students assisted by several scientists and volunteers:
Removed unwanted vegetation from an historic structure to prevent fire spread.
Completed a sacaton vegetation community restoration project by setting up a long-term study area to evaluate restoration techniques such as placing rock structures, fencing, ground scarification, and replanting. Students learned to grid and map, set up photo points for monitoring, and work with a local rancher to assist them.
Successfully ran a volunteer day to complete their restoration work. YES! students were responsible for leading the day’s events and managing all volunteers.
YES! 2014: Soil Erosion and Invasive Species Removal
Twelve students in nine sessions assisted by several scientists and volunteers:
Completed a sacaton vegetation community restoration project—they purchased five tons of rock and placed them strategically to reduce erosion and increase moisture and seed retention for the grasses; they placed downed mesquite limbs for erosion control and to prevent off road access by vehicles. Students purchased five more tons of rock for habitat improvement on another frog pond.
Successfully ran a volunteer day to complete their restoration work at the Cieneguita wetlands. Youth led 23 other volunteers in removing invasive species (cattails and bulrush) and transplanting spike rush to out-compete the non-native plants in two habitat ponds. YES! students were responsible for leading the days events and managing all volunteers.
Students completed an initial design and allocated funding an interpretive sign for the sacaton erosion project and funding smaller conservation signs for the Cieneguita habitat ponds.
YES! 2013: Cieneguita Ponds
Nine students focused on improving the Cieneguita ponds for aquatic species of animals and plants. They learned to identify a variety of grasses, sedges, and other native desirable plants.
Almost 50 Huachuca water umbel plants were transplanted to one pond and logs were added to protect small fish. Students developed our first volunteer day at the site, transplanting over 150 plugs of native grasses and removing dirt piles. Two television crews filmed their work and reported the story.
YES! 2012: Native Frog Habitat at Cottonwood Pond
In 2012, YES! was piloted with seven students, mainly from the Empire High School in Vail or connected with the Ironwood Tree Experience (formerly with Prescott College).
Seven students focused their efforts at improving Cottonwood Tank pond for future leopard frog reintroduction. They mapped the study area, propagated deer grass and planted, purchased rocks for stabilizing bank and water tank, laid out placement of fencing, established photo monitoring points, and designed educational signage for the site.
