This 4-part series provides the tools to evaluate livestock surface water risk & increase forage access under changing climate conditions.
Sufficient and high-quality water is essential for sustainable livestock production on Crown Range in British Columbia. This webinar series will introduce a method for assessing the climate change risks to surface water sources, and explain how to apply this process to water and range use management and planning.
The method uses future evaporation, climate moisture deficit and the flow accumulation model to evaluate future water reliability. Combining this process with forage resource data and other key rangeland characteristics allows you to plan for how climate change will affect water accessibility in areas with high value forage resources.
- The first two sessions will introduce the tools and approaches for assessing risk to surface water
- The third session will focus on application of risk assessment to water development considerations
- The final session provides an overview of three pilot projects that have applied the risk assessment and planning process to water developments on Crown Range in the Cariboo Region
The planning concepts are applicable to all parts of BC.
