Boreal Chorus Frog
Barely the length of your thumb, but the voice of early spring — this tiny treefrog fills mountain meadows with its rasping trill while ice still edges the ponds.
Meet the Boreal Chorus FrogUtah Frogs & Toads
Utah is famous for red rock canyons, salt flats, and open desert — not exactly the landscape you'd picture teeming with amphibians. And yet, 16 species of frogs and toads call this state home, from the alpine meadows of the Uintas to the canyon pools of the Colorado Plateau to the wetlands threading through the Great Basin. Water finds a way, and where water goes, frogs follow.
This site is a field-guide-style reference for anyone who wants to know what's calling from that muddy pond, which toad just crossed the trail, or why amphibian populations in Utah deserve our attention. Start exploring below, or jump straight to the full species list.
Utah's Four Frog Families
Utah's 16 species sort neatly into four major groups. Knowing which family you're dealing with narrows an identification down fast.
- True Frogs (Ranidae) — 4 species. Sleek, long-legged, and almost always found close to permanent water. This family includes the native Columbia Spotted Frog and the invasive American Bullfrog.
- Treefrogs (Hylidae) — 3 species. Small, often cryptically colored, with adhesive toe pads built for climbing. The Boreal Chorus Frog can be heard singing before valley snow has fully melted.
- True Toads (Bufonidae) — 5 species. Warty, terrestrial, and remarkably drought-tolerant. True toads range from sagebrush flats to pinyon-juniper country and are often the amphibians hikers encounter furthest from standing water.
- Spadefoots (Scaphiopodidae) — 4 species. Utah's most enigmatic frogs. Spadefoots spend most of their lives underground, emerging explosively after monsoon rains to breed in temporary pools. Blink and you'll miss them.

Four Species Worth Meeting First
If you're new to Utah's amphibians, these four will give you a feel for the remarkable range on offer.
Canyon Treefrog
Perfectly camouflaged against sandstone, this frog lives in the rocky stream canyons of southern Utah and is often heard long before it's ever seen.

Utah's most cold-adapted true frog, the Spotted Frog breeds in snowmelt streams and is one of the state's most important Species of Greatest Conservation Need.
Meet the Columbia Spotted FrogGreat Basin Spadefoot
A master of disappearance — this spadefoot can spend ten months underground, then breed, lay eggs, and raise tadpoles in a temporary pool before it dries up.

Utah's amphibians are distributed unevenly across a state that spans five distinct ecoregions. Knowing the terrain doubles your chances of a good encounter.
- Uinta Mountains & High Plateaus: The richest area for species diversity. Look for Columbia Spotted Frogs, Boreal Chorus Frogs, and Western Toads in beaver ponds, fens, and slow mountain streams.
- Colorado Plateau canyon country: Canyon Treefrogs and Red-spotted Toads occupy the rocky seeps and perennial stream pockets carved into sandstone.
- Great Basin valleys & wetlands: Spadefoots dominate the open desert, while the marshy edges of Great Salt Lake and Bear River refuge host a surprising number of species during wet years.
- Wasatch Front foothills: More accessible to most Utahns — Woodhouse's Toads breed in warm, shallow ponds, and Boreal Chorus Frogs colonize almost any seasonal wetland.

Identify Frogs by Sound
You'll often hear Utah's frogs long before you see them — a rattling trill drifting across a mountain meadow, a deep jug-o-rum booming from a reservoir, or a rapid bleating chorus erupting from a rain-filled ditch after dark. Each species has a distinctive call, and learning those calls is one of the fastest ways to know what's out there.
Our frog and toad call identification guide covers every Utah species, with audio descriptions, the seasons and times of night each species calls, and tips for distinguishing similar-sounding species. Whether you're standing at a pond in the dark or reviewing a recording on your phone, the guide will help you sort out what you heard.
A Word on Conservation
Amphibians are in global decline, and Utah is not insulated from that trend. Three threats stand above the rest here:
- American Bullfrog invasion. Introduced to Utah for aquaculture and as a novelty, the bullfrog is now established across much of the state. It outcompetes, eats, and displaces native frogs wherever it gains a foothold.
- Chytrid fungus (Batrachochytrium dendrobatidis). This waterborne pathogen has driven amphibian population crashes worldwide. It's present in Utah and a confirmed threat to several native species.
- Habitat loss and drought. Wetland drainage, livestock impacts on riparian zones, and longer, more severe droughts are shrinking the permanent water sources that native frogs need to reproduce.
Several Utah species — including the Columbia Spotted Frog and the Relict Leopard Frog — are listed as Species of Greatest Conservation Need under Utah's Wildlife Action Plan. Read the full picture on the conservation and threats page.
Help Count Them
Professional biologists can't be everywhere. Citizen science observations are genuinely useful data — and finding a frog you've never seen before is its own reward.
Two programs make it easy to contribute:
- iNaturalist — photograph any frog or toad you encounter and upload it. Your observations are reviewed by the community and flow into biodiversity databases used by researchers. Every record from a Utah wetland matters.
- FrogWatch USA — a structured monitoring program run by the Association of Zoos and Aquariums. Volunteers visit local wetlands repeatedly during breeding season and record what they hear. Training is free and the protocol is straightforward.
Before you head out, read the field tips for finding frogs — the right timing and technique make all the difference. If you want to identify what you're hearing at the water's edge, the frog call guide is an essential companion. And if you want to know exactly what species might be calling at your local pond, the complete Utah species list is a good place to start.
