California red-legged frog specialists
Trish Tatarian, MSc. and Greg Tatarian, of Wildlife Research Associates, will provide their expertise again in 2018 as instructors for this sought-after workshop. The workshop is comprised of one classroom and daytime field session, plus a night-time field session in small groups to allow for a more interactive experience with the presenters and species.  Class size is limited to 24 participants, with each night-time field session limited to 12 participants.

The classroom session will be held at the
Martinelli Event Center, 3585 Greenville Road, Livermore, and the field sessions are held at the Los Vaqueros Reservoir and Watershed.  Instructors will provide a lecture-style session with information about the taxonomy, phylogeny, distribution, bilogiy, population, habitat, movements, population biology, threats, management and regulation of the CA red-legged frog.  In the field, instructors will  demonstrate decontamination techniques, detecting frog eye shine, and capturing, handling, sexing, and measuring tadpoles and adult frogs.

Workshop Objectives

This is a great opportunity to receive training in species identification, field sampling techniques, and the habitat requirements of the California red-legged frog (CRLF). Workshop information will be useful for evaluating CRLF habitats, assessing potential impact from projects within the range of CRLF, conservation planning, and those who provide educational outreach to agricultural producers.  Intended audiences include biological consultants, land managers and planners, researchers, and resource agency personnel
