College students create wildlife habitats in a Wild Campus program

Students prepare to plant oak seedlings.
Put together a group of hard-working, do-good college students who care about environmental issues, and you end up with a really “Wild Campus.” At UC Davis, students formed the student-run Wild Campus organization two years ago to conserve wildlife in the greater UC Davis area.

Working with campus experts (such as faculty and staff in the Department of Wildlife, Fish and Conservation Biology) and local environmental and conservation organizations, the volunteer students are improving the habitats for local wildlife and engaging the public in hands-on activities.

This is an extraordinary program that gives the students real-world environmental management skills, along with leadership opportunities and communications experience. Professor John Eadie, Department of Wildlife, Fish and Conservation Biology at UC Davis, said of the Wild Campus program, “Hands-on activity is a huge part of the educational experience.”

Students plant tules in Putah Creek.
In the UC Davis Putah Creek Riparian Reserve, the students are establishing wildlife habitat areas and monitoring populations of amphibians, birds, fish, insects, mammals, and reptiles. They will record the changes over the course of time. Recent work in the riparian reserve (aka “the living classroom”) has included planting native oak seedlings, and installing tule plants to provide protection for the Western Pond Turtle, a species of concern.

A past project — Build a Wild Home Day — involved working with the UC Davis Arboretum on a successful public outreach program to build bird and bat boxes for installation on campus. (Great photos of this program are on the group’s Facebook page.)

The Wild Campus organization has a large cadre of eager and dedicated students who are improvising and making the most of limited resources. However, they are in need of donated field equipment (used equipment is fine) and financial contributions.

Visit the Wild Campus website and Facebook page for a feel-good look at what these ambitious students are doing to improve the environment, along with ways you can help them succeed.

Wireless networks could improve state water forecasting

A new wireless data collection system deployed at Duncan Peak, located near the town of Foresthill on the Middle Fork of the American River basin, is part of a new water information system for California. This extensively distributed sensor network will allow for better characterization on the amount of water stored in the snow and the soil throughout the watershed.

This wireless system is part of the research being conducted by University of California researchers as part of the Sierra Nevada Adaptive Management Project (SNAMP) to investigate the impacts of fuels treatment projects on water quality and quantity and how water is routed through catchments. Information collected from these wireless systems includes measurements of snow depth, temperature, relative humidity, soil moisture, and solar radiation. The data will also be integrated into models which will extend the results to areas where no measurements are being made.

Using one base station to log all the measurements and broadcast out over the landscape, it connects wirelessly to sensors up to 350 feet away, a distance that can be extended multiple times by placing “hoppers,” or signal relays, between the sensors and base station. This ‘mesh network’ insures multiple readings so no data is lost during transmission. Twenty more base stations are planned for instillation in the American River Basin.

The wireless system is made possible by the development of ultra-low power radios that can run on two AA batteries for up to two years and which can transmit data over long distances using the same technology as a home internet wireless network. This mesh radio network comes from DUST Networks.  Researchers Steve Glaser and Branko Kerkez from UC Berkeley, working with Prof. Roger Bales at UC Merced, have also installed a sensor network at their Critical Zone Observatory research site near Shaver Lake to monitor the same hydrologic variables as in the SNAMP sites. If the wireless system drops out due to extreme conditions, such as a snow storm or other malfunction, no problem! Each sensor also logs to a USB stick, from which the data can also be easily retrieved.

More precise estimates on water storage within a basin will lead to increasingly accurate predictions of water availability for use in hydropower, irrigation, habitat and household consumption.
