Why is the Oregon spotted frog at risk?

This frog is highly aquatic, usually found close to a source of water. Adults overwinter in ponds, seeps, rivers and streams, preferring areas where the water does not freeze, but they also overwinter under ice. Overwintering frogs are not necessarily torpid; they may be active all winter, even under the ice.

What are some interesting facts about the Oregon spotted frog?

Oregon spotted frogs eat mostly insects. Tadpoles eat algae and detritus (organic material) in the aquatic environment. These frogs are communal breeders that return to the same breeding areas each year. They require breeding sites in shallow water with short vegetation and full sun exposure.

What is the critical habitat for the Oregon spotted frog?

The Columbia spotted frog and Oregon spotted frog were the same species (“spotted frog”) until genetic analysis revealed they were two different species. While they have subtle color variations, they are morphologically indistinct. Therefore, geographic locality is used to determine species.

How many Oregon spotted frogs are left?

The decline of the Oregon spotted frog across its range is attributed mainly to the historical loss of wetland habitat; the continued degradation of aquatic habitats due to altered hydrology, introduction of non-native plant and animal species, loss of disturbance processes that maintained open-water habitat and

What are some interesting facts about the Columbia spotted frog?

Here we are designating approximately 65,038 acres (ac) (26,320 hectares) (ha)) and 20.3 river miles (mi) (32.7 river kilometers (km)) in 14 units as critical habitat in Washington and Oregon for the Oregon spotted frog.

How big is the Oregon spotted frog?

Oregon spotted frogs are nature's unsung stewards of biodiversity! Occupying a critical position in the food chain, their presence helps maintain a balanced ecosystem while preventing the unchecked proliferation of certain species.

How many Oregon spotted frogs are left?

Oregon spotted frogs have relatively short hind legs and extensive webbing between the toes of the hind feet. Sexually mature females range between 60 and 100 mm snout-vent length and males range between 45 and 75 mm (Licht 1975).

What are some interesting facts about the spotted marsh frog?
