Anyone visiting public lands such as National parks, forests, wildlife refuges or other publicly accessible natural areas has likely used a vault toilet. Convenient, durable and relatively easy to maintain, vault toilets are a staple at trail heads, picnic areas and roadside pull-offs across the country. They help to manage human waste in these natural areas, which see more and more visitation each year. But visitors may be surprised to hear that vault toilets present an unexpected entrapment hazard to wildlife.

Vault toilets mitigate odors from the underground storage tank by venting air through a pipe in the roof. This pipe, while malodorous and uninviting to us, can look enticing to animals that nest, roost or otherwise utilize cavities in trees and rocks, such as birds and small mammals. When the animals enter the vent and tumble into the tank below, they’re often unable to escape and sometimes perish in the dark, damp, confined space.

Thankfully for wildlife, there is a tidy fix for this messy problem. The Teton Raptor Center, widely credited as being among the first groups to address this issue, teamed up with staff from the U.S. Forest Service to create screens that fit over the vent pipes, keeping wildlife out while maintaining proper air flow. In 2011 the Teton Raptor Center launched a public-awareness campaign called the Port-O-Potty Owl Project; they’ve since helped to distribute and install thousands of these screens on vault toilets on public lands. Friends of Malheur is currently looking to raise money to purchase these screens for the four vault toilets currently installed at Malheur Refuge.

These screens are inexpensive, easy to install and immediately resolve the issue of animal entrapment in vault toilets. For the four screens required at Malheur Refuge, FOMR needs just $200. Please help us reach this goal and ensure that the Refuge’s vault toilets don’t pose unnecessary risks to wildlife.
