Ranching and California's Drought – A Workshop and Webcast

On November 7, 2014, we brought the U.S. Drought Monitor authors and the California State Climatologist to UC Davis to talk about 1) how the U.S. Drought monitor is updated weekly; and 2) how local expert knowledge, real time ranch impacts, and other relevant data can be used to inform the U.S Drought Monitor. We also shared new information on California Ranchers’ perceptions and experiences with drought, new livestock feeding strategies during drought, and seasonal weather forecasts for California. >>See Video and Presentations

Managing For Drought

Having a drought strategy is pertinent to the sustainability of any ranch enterprise, especially when faced with a winter that has thus far produced below normal precipitation following an extremely dry water year. We have provided info to help prepare for the various stages of a drought.

Ranchers' Perspectives and Management Strategies for Drought

Contact — Leslie Roche

Background. Over the past two years, we have been conducting a statewide mail survey and interviews of California ranchers in part to 1) improve connections between ranchers' and researchers' knowledge bases to identify strategies to adapt to challenges like drought; and 2) compile and share the knowledge and expertise of experienced ranchers. Information on the mail survey can be found in Lubell et al. 2013, and information about the rancher interviews conducted can be found at the California Ranch Stewardship Project.

Preliminary Results. In 2011, we asked 509 California ranchers, "If another drought were to begin this year, how severely would this impact the economic viability of your operation?" Nearly three-quarters of respondents (n=477) indicated the impact to their operations would be as severe or worse than past droughts, while only 12% indicated the impact would be less severe than in previous droughts. In recent in-person interviews across California, 76% (n=60) of ranchers stated they expected to see impacts to their operations if drought conditions persisted into the coming year—and 35% of those interviewed expected devastating impacts to the viability of their operations. Several ranchers interviewed noted that a statewide severe drought would exacerbate the effects of earlier consecutive droughts in their regions.

Impacted more Severely than Expected by Last Drought


(n= 477)

Lost grazing capacity


Reduced winter forage availability


Lost Profit


Lower calf weaning weights


Reduced reproduction rates


Shortage of livestock drinking water


In the statewide mail survey, nearly all ranchers (99%; n=443) reported that they had employed reactive drought strategies—using at least one or a combination of management practices in response to drought. A majority of ranchers (64%; n=443) also reported that they utilized proactive drought strategies—using at least one or a combination of practices to prepare them for potential future drought.

Strategies to Manage for Drought Impacts


(n= 443)


Employ conservative stocking rates


Incorporate pasture rest into grazing system


Incorporate both cow-calf and stockers for flexibility


Grass bank/Stockpile forage


Use 1-3 month weather predictions to adjust stocking


Add other livestock types for flexibility



Reduce herd size


Purchase feed


Apply for government assistance programs


Wean early


Rent additional pasture


Move livestock to another location


Earn off-ranch income


Sell retained yearlings


Place livestock in a feedlot


Allow livestock  condition to decline; maintain herd size


Add alternative on-ranch enterprise


Rancher experience and knowledge (i.e., number of generations ranching, number and quality of information sources, and education level) positively influenced ranch goal setting—specifically, prioritization of forage production goals—and the management toolbox (i.e., number of active conservation programs, number of key practices used, and diversity of forage resources). Goal setting and the management toolbox had direct positive effects on adaptive strategies for drought impact management—including the number of proactive and reactive drought management practices used, and having an in-place drought management plan.

Conceptual Model linking Experience Knowledge Management Goals to Drought Adaptation

Next Steps. We are currently wrapping up analysis of the survey responses and are developing research papers and extension education products. We are continuing to interview ranchers across the state.

Estimating Cost of Replacing Forage

"Calculations take into account the forage productivity of the site, the reduction in productivity due to a disturnbance, the RDM standard necessary to protect the site, the grazing efficiency of grazing livestock, and the number of acres affected. In addition, the final worksheet in each file calculates the cost of replacing lost forage with comparable hay." >>More



Q&A: Tax Options for Drought Sales of Livestock

" If a producer is forced to sell livestock, in excess of normal levels, due to shortages of water, feed or other consequences of drought, the income tax on the gain from the sale of those animals may be postponed. " >>More




Weather-Related Sales of Livestock

" There are two provisions in tax law which attempt to cushion producers from the consequences of adverse weather-related livestock sales. Under the first provision, livestock held for draft, breeding or dairy purposes and sold due to adverse weather are provided a two-year reinvestment period... The second provision, which applies to all livestock (other than poultry), allows cash basis taxpayers whose primary trade or business is farming to defer receipt from sales in excess of normal business practices due to weather-related conditions that result in a disaster declaration area." >>More

Top 10 Drought Management Tips for Ranchers

" 1. Adjust stocking rates to match drought-induced reductions in forage yield, in order to avoid longterm damage to the base forage resource. Several feasible options exist to effectively reduce stocking rates on pastures. Consider early weaning to reduce the quantity and quality of feedstuffs needed to meet cow nutritional requirements.

Limit Feeding Concentrate Diets to Cows

" In years when hay and forage production is low due to drought, hay prices often escalate and in severe cases, forage of any kind may be hard to come by. In situations like this, some producers should consider limit feeding concentrate diets to cows. Depending on the price of grain, nutrients to maintain and grow cattle may be cheaper to purchase through concentrate feeds rather than roughage. " >>More



Evaluating a Early Weaning Drought Management Strategy

" It can be challenging to cost effectively lease pasture, feed energy, or sell cows just to buy them back when forage production improves. Early weaning, especially when combined with one or more of the other options listed, can be a useful tool to manage forage supply while minimizing the need to feed energy or dramatically liquidate cattle.
