Northern Leopard Frogs are Back at Matheson Preserve!

Northern leopard frogs experienced a surprising resurgence this summer after fires and flood at Matheson Preserve. Learn more about these resilient amphibians!

Northern leopard frogs were historically found throughout Southern Canada, and the northern, Rocky Mountain, and Intermountain regions of the United States.  Learn more

A species of concern in Utah, the northern leopard frog's decline from much of its historic range is likely due to a combination of ecological factors such as pollution, deforestation, and water acidity. Read more

The Matheson Preserve provides a variety of habitats these amphibians need to survive, from slow-moving or still water along streams and rivers to wetlands and permanent or temporary pools.

Between March and June, female frogs lay up to 6500 eggs in a pond where the tadpole can develop to adulthood over the next 2-4 months.  Learn More.

During their development, northern leopard frogs must evade snakes, raccoons, other frogs, and even humans (who eat and conduct groundbreaking medical research on them) to survive.

Once they reach adulthood, these carnivores will eat almost anything that fits in their mouth, including mosquitoes, beetles, ants, flies, worms, smaller frogs (including their own species), and even birds and garter snakes.  See more

This year's re-emergence at Matheson Preserve is "probably due to the wet year we had," said Linda Whitham, Central Canyonlands Program Manager at the Conservancy. Read more in the Winter 2011 issue of Basin, Range & Rimrock (.pdf, 954 kb).
