Dr. Jeff Wilkinson is a herpetologist with more than 20 years of research experience in the phylogenetics, biogeography, taxonomy, natural history, and ecology of reptiles and amphibians. He is authorized under HTH’s 10(a)(1)(A) permit from the U.S. Fish and Wildlife Service to handle California red-legged frogs and California tiger salamanders throughout their ranges, and he is a Level II surveyor for the blunt-nosed leopard lizard. In addition, Jeff possesses a current scientific collecting permit for reptiles and amphibians in California, including species of special concern and the threatened California tiger salamander.

Jeff has conducted impact assessments andspecies-specific surveys, and relocated and monitored numerous reptile and amphibian species, including the Alameda whipsnake, San Francisco garter snake, giant garter snake, blunt-nosed leopard lizard, California red-legged frog, foothill yellow-legged frog, mountain yellow-legged frog, western spadefoot toad, California tiger salamander, Santa Cruz long-toed salamander, and western pond turtle. Jeff also has:

  • Designed mitigation and monitoring programs for the California red-legged frog and the California tiger salamander in Alameda and San Mateo counties and for the western spadefoot toad in San Luis Obispo County
  • Supervised a significant translocation of foothill yellow-legged frogs in the upper reaches of Coyote Creek in Santa Clara County
  • Served as the senior herpetologist on a large development project in Alameda County, for which he supervised a large survey, translocation, and monitoring program over several years
  • Translocated approximately 800 adult frogs and 3000 tadpoles and estimated population sizes for red-legged frogs in three conservation areas using mark-recapture techniques over a 3-year period
  • Managed a team for a 3-year survey of the blunt-nosed leopard lizard in California Valley, San Luis Obispo County, and surveyed for and translocated adult western spadefoot toads from an impact site to a mitigation site for a large solar power project

Jeff is also a research associate at the California Academy of Sciences, conducting research and publishing peer-reviewed papers on various reptiles and amphibians, including the California red-legged frog and mountain yellow-legged frog.

Jeff received a Ph.D. in zoology from Texas Tech University and M.S. and B.S. in zoology from Brigham Young University.
