American bullfrogs wreaking havoc in Fraser Valley watersheds

Fraser Valley Conservancy helping folks to ID native frogs around them and improve habitat

The American bullfrog has the potential to wreak havoc on Fraser Valley ecosystems, according to the Fraser Valley Conservancy.

The voracious bullfrogs can easily gobble up at-risk native frogs, and other wetland creatures with abandon across the Fraser Valley.

The FVC is getting the word out and asking residents who find frogs on their properties from Langley to Hope to let them know.

“Maybe the sheer size of this adult female we found in Chilliwack can paint a picture for you,” according to the recent post by Fraser Valley Conservancy (FVC).

Part of the problem is that bullfrog populations are often spread by humans.

“Bullfrogs are common in some areas of the Fraser Valley,” according to the FVC’s info sheet, ‘What’s the deal with bullfrogs?’

The large frogs are known by their deep ‘barrum-barrum’ call at night, and have been found in Sardis Park in Chilliwack, Mill Lake Park in Abbotsford, but not the Cheam Wetlands near Agassiz, according to examples given by FVC.

“The best thing you can do to help our native creatures is to improve the habitats where they live.”

Folks should never move amphibian eggs, tadpoles, or adults from one pond to another. Once they are established and breeding they are incredibly hard to remove.
