Life history of Bufo boreas boreas on the Colorado Front Range. The boreal toad (Anaxyrus boreas Boreal toad is one of two subspecies of the Western toad (Anaxyrus boreas, formerly Bufo boreas), which is found throughout much of western North America (Stebbinsp. map 32).

The subject of this Species Status Assessment (SSA) Report is the. serve toad populations. Boreal Toads (Bufo boreas boreas) are declining throughout much of their range in western North America (Corn ); documenting their movement patterns may prove integral to understanding and arresting the declines.

Studies of toad movements often. Boreal toads escape threats by jumping into a body of water and diving all the way to the bottom. Habitat. The Boreal toad lives in high elevations between 5, to 10, feet. They live in many different aquatic habitats and are often found away from water.

Boreal Toad (Bufo boreas boreas) Conservation Plan. The boreal toad (Bufo boreas boreas) shows declines in population size and distribution across its range in western North America. The population in the Southern Rocky Mountains (Wyoming, Colorado, and New Mexico) is particularly vulnerable to extinction during declines as it is geographically isolated from all other populations of boreal Size: 3MB.

Boreal toads (Bufo b. boreas) are widely distributed over much of the mountainous western United States. Populations in the Southern Rocky Mountains suffered extensive declines in the late s through early s (Carey, ). At the time, these mass mortalities were thought to be associated with a bacterial infec-tion (Carey, ).

Evol., –, discussed mtDNA phylogeography and provided evidence that (1) nominal Anaxyrus boreas is a complex of species that do not conform to the current arrangement of subspecies, Anaxyrus boreas boreas and Anaxyrus boreas halophilus; (2) nominal Anaxyrus boreas is paraphyletic in terms of mtDNA haplotypes with respect to Anaxyrus.

Moreover, understanding movements can be essential to predicting the population-level effects of some ecosystem alterations (e.g., habitat alteration, creation of barriers to movements, or introduction of predators along travel corridors) and to planning habitat restoration that will conserve toad populations.

Boreal Toads (Bufo boreas boreas Cited by: The boreal toad (Bufo boreas boreas) is one of two subspecies of the western toad found in the western United States (Figure 1).
