Adaptive Decision-Making for Sustainable Working Rangelands
Insights from rancher and rangeland manager decision-making
Rangelands span diverse ecosystems, representing a majority of the world’s land resources, and therefore hold great ecological, economic, and social value. In California, rangelands cover ~50% of the state, and are often at the nexus of wildland, agricultural, and urban landscapes. These working landscapes support a broad range of ecosystem services—including food and forage production, water resource protection, biodiversity, and wildlife habitat. Therefore, the long-term sustainability of these lands and the services they provide is not only critical for ranchers and rangeland managers but also for the broader public.
Ranchers and land managers hold unique, place-based experience and knowledge about the challenges and opportunities to support sustainable working rangelands. Teaming up with scientific, management, and agency partners, we have conducted over 1,000 surveys and interviews with ranchers and land managers across California and beyond to gain deeper insights into the factors shaping sustainable rangeland management.
Research Highlights
Working with partners across California and beyond, we have surveyed and interviewed ranchers and land managers to gain insights into key factors shaping rangeland decision-making, perspectives on effective management practices, and ranching information sources.
Sustaining working rangelands: insights from rancher decision-making
The California Rangeland Decision-Making Survey revealed substantial variation in ranch structure and management goals, underscoring the difficulty of applying uniform practices and policies. To support long-term sustainability, rangeland policy-makers should engage local leaders, social networks, and trusted organizations.
On-ranch grazing strategies: context for the rotational grazing dilemma
Debate has long persisted on the effectiveness of rotational grazing systems for conservation and agricultural goals. In a survey of California and Wyoming ranchers, we found that while two-thirds use rotational grazing and report benefits, intensive rotational strategies are less widely adopted. The focus of much grazing research on intensive rotational strategies contrasts with the extensive rotational practices commonly used on ranches. This study underscores the need for enhanced communication and participatory research between scientists and ranchers to align research with on-ranch management practices.
