The salt marsh harvest mouse (Reithrodontomys raviventris) is an endangered species endemic to the San Francisco Bay Area. On September 10, 2019, Dr. Katie Smith (lead instructor) and Laureen Barthman-Thompson (co-instructor) will present a workshop on the biology and conservation of the species. Katie, who works for WRA, has studied the salt marsh harvest mouse extensively and received her Ph.D. from UC Davis. Laureen is a wildlife biologist with the California Department of Fish and Wildlife and has worked on salt marsh harvest mice for over 20 years.


This workshop is being jointly offered by the Coastal Training Programs of the Elkhorn Slough and San Francisco Bay National Estuarine Research Reserves.


Workshop Format

The workshop consists of a daytime classroom session mixed with three field trips throughtout the day on Tuesday, September 10, 8:00 am - 6:00 pm. The classroom session will take place at the Rush Ranch Nature Center. The field trips will take place in the Rush Ranch vicinity, with specific locations TBD. Field trips will happen in the morning, mid-day, and in the afternoon, interspersed between classroom sessions.


Workshop Objectives

  • Gain a better understanding of the biology of salt marsh harvest mice
  • Provide insights into management concerns, techniques, and solutions
  • Improve field biology skills, and in particular learn about conducting site assessments
  • Provide an opportunity for practitioners to network


Topics Addressed

  • Taxonomy and species identification
  • Biology and life cycle of the species
  • Population distribution
  • Habitat requirements and assessment
  • Population movement
  • Threats
  • Regulatory issues


Field Training Practicum

Participants will receive  training on habitat requirements and habitat assessments of the salt marsh harvest mouse. Katie and Laureen will lead participants through field discussions about how plant species and structure are important to salt marsh harvest mouse, high tide refuge, microhabitat use, differences between tidal and diked wetland habitat, sea level rise and tidal restoration concerns.


* Please Note - the field component of this workshop is now different from our original announcement


*Very Important*

It is important to note that no component of this workshop should be construed to apply to attendee’s ability to obtain permits for salt marsh harvest mouse; if you are interested in how workshop activities might be used for permitting, you are encouraged to contact your agency permitting representative.
