About this file
This document is an informational guide about the Yosemite Toad, a federally threatened species found in terrestrial habitats above 6,400 feet elevation. The guide provides detailed facts about the toad's lifecycle, habitat, and critical conservation considerations, including that they live 12-15 years, mature slowly (3-5 years for males, 4-6 years for females), and spend most of their lives in dry environments like rodent burrows, rock crevices, and around decaying stumps.
The document offers specific guidelines for minimizing habitat disruption, such as avoiding walking across sandy areas with lupine, checking for rodent burrows before parking or turning vehicles, not piling materials near old stumps, and carefully relocating toads only when absolutely necessary. If a toad is encountered, the guide recommends documenting the sighting by taking a GPS point, clear photographs of the animal and habitat, and noting environmental conditions. The document emphasizes the importance of preserving micro-habitats and preventing unintentional barriers to toad movement, providing visual examples of toad locations in various environments.

YOSEMITE TOAD (FEDERALLY THREATENED) TERRESTRIAL HABITAT INFORMATION
• Yosemite toads can live 12-15 years
• They don’t mature until 3-5 yrs (males) or 4-6 yrs
(females)
• They can move 0.78 miles or farther from a breeding meadow and are found above 6,400 ft. elevation.
• Toads move around during the day and night, especially during summer rain events
• Toads hibernate underground from early October through May and emerge as the snow melts
• Toads spend most of their lives in dry terrestrial habitats in rodent burrows, under rock or log crevices, or in burrows around old decaying stumps
Watch Outs/To Do’s Toads can be under logs or rocks, in burrows located in areas like open spaces or along roads.
• To minimize impacts to toads and habitat please:
o Don’t walk across open sandy areas with lupine.
o Don’t park or turn vehicles around in open sandy areas unless you check that no rodent burrows are present.
o Avoid walking through areas with lots of rodent burrows.
o Don’t pile materials on or within 15 ft of old stumps.
o Don’t scatter cut materials that would create a dispersal barrier to toads.
o Flag and avoid the micro habitats where you find a toad in your work area.
• If you find a toad, please do not disturb it unless it is an emergency to move it out of harm’s way. With clean hands (no bug spray/lotion/sunscreen residue), relocate to an area in the direction the individual was traveling out of harm’s way.
• Document sightings by:
Take a GPS point (make sure you know your units (NAD 83)) Take a clear photo of the animal if possible Take a photo of the overall habitat where found Note anything unusual and general comments about the encounter (i.e. time, weather)
