“We’re trying to get [bat boxes] out into the community so that we can support local bat populations by giving bats somewhere safe to sleep that’s free from predators and disease,” Taryn Muldoon, a second-year biology student at Acadia University, told CBC’s Mainstreet on Friday.
The bat population in the Annapolis Valley has been decimated over the last 10 years after a fungal infection called white-nose syndrome appeared in Canada.
The fungus grows on any exposed skin on the bat and replaces muscle fibres and blood vessels, which causes tissue and electrolyte loss — killing the bats.
“We’ve lost the majority of the bats that hibernate here in the province,” Andrew Hebda, the retired curator of zoology at the Nova Scotia Museum of Natural History, said in the interview with Mainstreet.
Hebda’s been studying bats since the 1970s.
“We estimated that 25 years back, we had approximately 200,000 bats over wintering here. We figure it’s probably in the vicinity of around 10,000 now,” he said.
“In Nova Scotia, we estimated [bats] were consuming in excess of 60 metric tons of insects every single year and that’s a lot of insects — things like mosquitoes, small midges and small moths,” he said.
That’s why Muldoon and Zackery Pate, a third-year environmental sustainability student at Acadia, launched the Annapolis Valley Bat Box Project.
The students, along with volunteers, have started building wooden bat boxes to serve as refuge for the population.
Quest for the best bat box
Pate, who came up with the idea, said the boxes will also provide more data about the winged mammals.
“We took a look at a few [types of boxes] and we have more in the works … it’s really about gathering the data once these are out and really analyzing what makes a bat box, a good bat box,” he said.
The boxes must serve as a roost for bats to digest all the insects they eat at night, and also a place to stay warm and sleep during the day.
Muldoon said the team is trying to get instruments installed in some of the boxes to measure the temperature and humidity required for the bats.
“Education is a huge component of this project, because one really important way to support bats is engaging people about bats and the issues that they face and how amazing they are,” she said.
With that in mind, the team created a two-hour educational webinar with bat experts, conservationists and those who help wild animals from across North America.
“That has been very important and that’s something that we’re still striving to move ahead with as we distribute the boxes,” Muldoon said.
The webinar is expected to be available on their Facebook page next week. Those interested in watching the webinar can email the team directly.
So far, the team has built 30 bat boxes which will be distributed throughout the Annapolis Valley.
Bat boxes can be requested by contacting the Annapolis Valley Bat Box Project.
