Ecology of the California Red-legged Frog Workshop

Check back soon for updates regarding the 2018 California Red-legged Frog Workshop, or read more about what the 2017 workshop entailed below. 

The Conservation Partnership will hosted its 13th consecutive California red-legged frog workshop April 19th and 20th in Alameda County. California red-legged frog specialists
Trish Tatarian, MSc.  and Greg Tatarian, Wildlife Research Associates, joined us again in 2017 as instructors for the workshop. The workshop was comprised of day and night-time field sessions in small groups to allow for a more interactive experience with the presenters and species.  Class size was limited to 24 participants, with each night-time field session limited to 12 participants. The classroom session was held at the Martinelli Event Center, 3585 Greenville Road, Livermore, and the field sessions were held at the Los Vaqueros Reservoir and Watershed.  Instructors demonstrated 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 (under Important Information) the required and suggested equipment for the workshop field sessions. This is especially important as suitable binoculars and SPECIFIC FLASHLIGHTS ARE HIGHLY RECOMMENDED FOR THE TRAINING, and it MAY TAKE TIME to locate one.

Workshop Price

$475 – Includes breakfast and lunch. Confirmed registration is on a first-come, first-served basis, upon receiving payment, through our online registration portal. Information on required equipment can be found below.

Tickets are on sale now through EventBrite!

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 20th
8 am to 2 pm –
Overview of the ecology 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 19 OR April 20: 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.
