![]() We are involved in several studies aimed at learning more about bullfrog invasion dynamics and whether bullfrog removal at sites where the two species co-occur could benefit Oregon spotted frogs.Įxplore the science pages in the tab above to learn more about American bullfrog research at FRESC. Many of the flowering shrubs are excellent choices for garden borders and wildlife gardens. They include plants of all statures, from towering trees to creeping groundcovers. Bullfrogs are much bigger than Oregon spotted frogs and tend to live in the same habitats. Plants native to the Pacific Northwest are some of the most attractive plants for gardens anywhere in the world. Oregon spotted frogs are susceptible to competition and predation by bullfrogs. In the western United States, bullfrogs have the potential to slow recovery of the Oregon spotted frog, a Threatened species under the Endangered Species Act. To help control the spread of invasive bullfrogs and protect local food webs, land and resource managers need information on when and where bullfrogs are invading and interacting with native species. After introduction, bullfrogs are capable of thriving and quickly reproducing in a wide range of habitats. Bullfrogs are usually introduced into new habitats through human activities like the pet trade or bait for recreational fishing. They can also spread disease in areas where they have invaded. Plants are arranged by the soil moisture needs, starting with the wettest. These large frogs compete with smaller species for food and space. You get the best results by putting the right plant in the right place, but these plants cut you more slack than most. They are frequently linked to population declines of native species, including smaller native amphibians. American bullfrogs are native to eastern North America but have been widely introduced around the world. ![]()
