Workshop on the Biology & Management of the
California Red-legged Frog
April 22 and 23, 2015       


The Alameda County Conservation Partnership and Los Vaqueros Reservoir & Watershed are pleased to host this workshop for the 11th consecutive year, co-sponsored by the San Francisco Bay National Estuarine Research Reserve Coastal Training Program. California red-legged frog specialists Trish Tatarian, MSc.  and Greg Tatarian, Wildlife Research Associates, will be the instructors. The workshop includes day and night-time field sessions 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 Center, 3585 Greenville Road, Livermore, and the field sessions will be held at Los Vaqueros.

Personal vehicles are required for traveling to the site; a liability waiver is required (see below under Important Information to complete) upon registration. Instructors will demonstrate decontamination techniques, detecting frog eye shine, and capturing, handling, sexing, and measuring tadpoles and/or adult frogs. Please review the Equipment list and Criteria for Selecting Light Sources and Binoculars documents below below (under Important Information) regarding the field sessions and the required and suggested equipment. This is especially important as suitable binoculars and SPECIFIC FLASHLIGHTS ARE HIGHLY RECOMMENDED FOR THE TRAINING, and it MAY TAKE TIME to locate one.

$450 – Includes breakfast and lunch. Confirmed registration is on a first-come, first-served basis, upon receiving payment, through our online registration form below. Information on required equipment can be found below.

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 (CRF). Workshop information will be useful for evaluating CRF habitats, assessing potential impact from projects within the range of CRF, 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. Please note: regulatory topics will not be covered in detail.

Workshop Agenda

April 23rd
8 am to 2 pm –
Overview of biology and management of the California red-legged frog. Demonstration of equipment, frog identification, and PIT-tagging and radiotracking techniques.

2 pm to 6 pm – Field Site Instruction
Habitat requirements, corridors, pond designs, metapopulation dynamics, tadpole identification, and survey techniques. Personal vehicles required to travel to field site and liability waiver required.

April 22 OR April 23: 8 pm to 12 am – Night Field Session (choose one of two sessions) 
Night-time survey techniques. Trish and Greg Tatarian will demonstrate USFWS survey methodology, as well as catching, handling, sexing, and measuring of adult frogs. Students can then practice these methods at various ponds.

Please note: this workshop is not intended to satisfy all requirements to obtain CRF permits from the U.S. Fish and Wildlife Service. Please contact the agency for further information if obtaining a Federal permit is your goal.


Trish Tatarian has conducted over 10 years of telemetry research on California red-legged frog populations at various locations between the coastal populations and the Sierran populations, identifying movement parameters, terrestrial habitat requirements and chytrid infection rates per site. She's also a CEQA/NEPA consultant who works with private developers, State and federal agencies as a general ecologist, specializing in special-status amphibian, bird and mammal surveys.

Greg Tatarian - partner with Trish in Wildlife Research Associates, established in 1991, has worked for many years alongside Trish, conducting California red-legged frog surveys, assessments, radio telemetry studies, chytrid sampling and construction monitoring. Greg is a bat specialist, and holds a California Scientific Collection Permit and MOU with the California Department of Fish and Wildlife for bat research and surveys involving radio-telemetry, banding, genetic sampling, mist-netting and harp-trapping. Greg has extensive experience with bats in buildings, bridges, and other man-made structures, as well as natural habitat.
