The amphibian monitoring program first started in 2023 and is to better understand, detect and record amphibians that live in Esquimalt Gorge Park. Understanding the amphibians that inhabit the park can aid in future restoration, habitat enhancement, outreach, interpretation, community connections, and understanding the biodiversity of the park. The main study subject of the monitoring program is the Northern Pacific Treefrog (Pseudacris regilla). 

The Northern Pacific Treefrog can change colours. Their main colours are green to brown, however, they can have bronze, blue, and yellow colouration and stripes or splotches of colours on their back. The dark mask that runs nose to shoulder and their distinct circular toe pads are two key identifying characteristics. 

Staff and volunteers monitor amphibians rain or shine, and amphibians typically love the rain! The sound of the male Northern Pacific Treefrogs’ breeding call can be heard on warm and rainy spring nights after sunset. 

If you see a frog in the park, take a photo and upload it to iNaturalist! Do not touch or hold amphibians because anything on our hands, including our natural oils, sunscreen, lotions, and makeup can be extremely harmful to them. Amphibians rely on their skin to breathe and drink water.
