Plenary Speaker

Place-Based Regeneration: An Agricultural Process

“Place-Based Regeneration: An Agricultural Process” is grounded in the work of White Buffalo Land Trust at the 1,000-acre Center for Regenerative Agriculture at Jalama Canyon Ranch. Located in California’s Central Coastal ecoregion, we explore our work through hands-on experiences with livestock management, perennial agroforestry, and watershed restoration. This presentation delves into the unique characteristics of our place, the time in which we work, and the fabric of our community. We examine the specific opportunities and challenges we’ve encountered, and how these shape our practices, desired outcomes, and monitoring methods. By sharing the principles that have guided our work and the insights we’ve gained, we aim to deepen the understanding of regenerative processes that lead to soil health, enhanced water cycles, promoted biodiversity, and improved human and community well-being.

After earning my Veterinary degree, I specialized in Food Animal and Preventative Medicine, achieving a board certification from the American Board of Veterinary Practice. As a Fulbright Fellow in India, I worked on zoonotic infectious diseases of cattle and water buffalo. As an Intern and affiliate faculty member, I trained veterinary students in Clinical Practice and Production Medicine while earning an Epidemiology MS and creating a Contract Research Organization, Dairy Research & Technology, LLC (DR&T), to conduct over a dozen Clinical Trials for FDA and USDA approval. DR&T continues to conduct discovery and development work for human and veterinary biologics. As Research Director for PanTheryx, Inc., I developed intellectual property and conducted in vitro and in vivo studies in collaboration with universities for several, successful infectious disease programs for Clostridium difficile, norovirus and rotavirus. Our Food for Special Dietary Use, DiaResQ, provides patented passive immune prophylaxis and therapy for infectious diarrhea globally. As CSO for the Bridge Institute Global BioShield project in collaboration with CSU Infectious Disease Research Institute, we created a natural intranasal polyclonal antibody to prevent SARS COV2 infection in humans. With my husband, award winning veterinarian and nutritionist, Dr. Arden Nelson, we provided education to veterinary and producers around the world and owned and operated a certified organic, grassfed, specialty farm.

Tracy Shane is a university researcher and educator who initiated the Drone Rangers as a group of researchers and students focused on understanding the uses of drones in grassland and rangeland management and engaged in education and outreach in this area of study. With her Drone Rangers team, Ms. Shane focuses on answering questions such as: how effective are specific grazing treatments for achieving management objectives; how much do targeted grazing treatments reduce fine fuels and alter wildfire behavior?; and, which emerging technologies are cost effective for improving grazing management? As a certified professional in rangeland management, Ms. Shane has been working with livestock producers and in the field of range management for 24 years.

Plenary Speaker

Drone technologies for forage and grazing management

During this workshop/presentation, participants will learn about innovations in drone-based technologies for improving management of forages and grazing management. Topics covered include: improvement of estimates of available forage, identification of species/functional groups, and tracking management success. This presentation will also touch on how to get started with drones and identifying appropriate sensors for the data that livestock producers want to collect.

Dave Shields along with his wife Ginger and children operate Pastured Life Farm in O’Brien Florida. Born and raised in Jacksonville, Florida, Dave’s first career was in IT & Network Services, culminating in the building and operation of a data center and network infrastructure & security consulting businesses.

After growing tired of the corporate hustle, with no agrarian background, in 2007, Dave and his wife decided to relocate their family to the rural farmlands of Florida. For the first couple of years, Dave and his family embarked upon many animal operations while Dave telecommuted to work.

After years of management, and through the careful implementation of their pastured poultry program, Pastured Life Farm now produces a wide variety of pasture-based proteins. Today, their farm provides direct farm to consumer products to thousands of customers in Florida.‚Äč

Innovation and Moving the Needle Forward

As stakeholders in a democracy with around 161 million people registered to vote, pushing any issue forward begs us to ask what the best way for going about it is. In a 161 million person democracy, organizations embrace mass media and technologies able to communicate and build bases widely. As a national organization informed and seasoned in building bases, we not only want to communicate and build bases widely, but also build resilient bases, from whom strong leaders can emerge. How does one do this with social media and mass media technology? Finally, at Young Farmers we believe in innovative policies that speak to a 161 million person democracy, and in a culture to ground this work in, a culture that can host such an effort.

Country Natural Regenerative Ranching Director
Dan Probert has spent his entire life in the Cattle Ranching business. Growing up on a ranch in Eastern Oregon, Dan moved to the central coast of California and started his own ranching enterprise in 1982. Dan moved back to Eastern Oregon in 1994 where he now ranches near Joseph Oregon. Dan also manages the resources on cow/calf and yearling operations in central Oregon and Washington.
The past 25 years Dan has been involved with the Country Natural Beef Cooperative first as a member then as its Production coordinator and served as its Executive Director for 5 years. Dan currently holds the title of Regenerative Ranching Director for Country Natural Beef. CNB is a cooperative of family ranches that has been in existence since 1986. Currently CNB is 100 members strong and markets 65,000 animals per year to companies like Whole Foods, New Seasons Markets, and Sysco. Dan also was on the board of the Global Animal Partnership animal welfare board for 10 years.
Currently, Dan is working with Country Natural Beef ranchers, Sustainable Northwest and Northway Ranch Services to build and implement a regenerative ranching program that will involve more than 100 ranchers across the west. The program seeks to bring sustainable ranching practices to the forefront and document the continued success of regenerative ranching practices implemented on their lands.

Partnership on the Prairie

The focus of the presentation will be to talk about our collaboration with The Nature Conservancy, Country Natural Beef, Sustainable Northwest and other groups that we work with to acheive mutual outcomes on our ranch onthe Zumwalt Prairie. Also highlighting the good work that Country Natural Beef is doing beyond our ranch in working with over 90 ranches in the west to create a regenerative program that focuses on continuous improvement.
