Student’s Bat Box Project Aims to Fill Data Gap
FOR IMMEDIATE RELEASE
As part of what will become a culminating undergraduate research project, Loeblich is constructing 10 plywood houses to be placed at the University Farm and Big Chico Creek Ecological Reserve. She’s using power tools and other equipment in the Department of Art and Art History’s workshop under the guidance of shop technician David Barta.
When completed, the 100-bat-capacity structures will be installed at the top of 20-foot poles with special listening equipment that will collect data on the animals’ species and numbers and patterns in feeding, breeding and migrating.
Loeblich plans to share her research with area farmers and others to educate the community about bats and their potential uses in the area’s economy. Since bats feed on disease-spreading insects like mosquitos and moths, she said, they could be used to replace harmful chemical pesticides in farming and other applications.
“Northern California is one of the top agricultural producers in the world,” she said. “You’d think we’d have more data by now, but it’s just not there.”
Loeblich said that each night, bats eat their weight in insects – about 50 grams worth, or up to 1,000 insects per night. But each farming season, myriad bats die from pesticide overdoses.
Most California bat species are sensitive or threatened, she said, and some are on the endangered species list.
“Most people don’t know anything about bats as a species, or they associate them with vampires,” she said. “Only three species are actually vampires, and only one of those preys on humans. Bats are really important to California’s economy and environment.”
The $8,000 research project is being funded through an award from the Associated Students Sustainability Fund and two smaller campus research awards. Loeblich also received a $50 gift card from Home Depot, which she used to purchase materials.
The majority of the funding is going toward purchasing acoustic equipment – boxes with microphones. Because bats eco-locate at frequencies higher than humans can hear, special equipment is needed to pick up their sonar signals. Bats’ individual frequencies can be used to identify their species and gather data on their size, prey, sleeping habits and more.
Last week, Loeblich completed the time-consuming task of using a table saw to cut shallow grooves into the sides of dozens of planks to be used for the boxes’ inner walls. The grooves will act like a ladder and give the clawed bats something to cling to in the houses.
Taking a break from her work, the Yuba College transfer student and U. S. Air Force veteran surveyed the wooden planks around her and smiled.
“My junior high shop teacher told me I’d never go anywhere or do anything with shop,” she joked. “I wish he could see me now.”
