In 2018, as the Camp Fire was still burning in Butte County, a number of University of California colleagues, led by Area Dairy Advisor Betsy Karle, sampled irrigated pasture forage, hay, and corn silage from locations throughout Northern California (including several pastures here in Placer and Nevada Counties). Some of these regions had been impacted by ash fall and wildfire smoke; others had not. Our intent was to learn if ash created any potential toxicity or other health problems for livestock. We were especially interested in looking at heavy metal concentrations.

As we once again find ourselves in smoky conditions, I thought it might be helpful to provide an overview of our findings. For the most part, we did not find any concentrations of metals, minerals, or other compounds that should cause concern for livestock producers. Similarly, Tracy Schohr, who is the Livestock and Natural Resources Advisor for Butte, Plumas, and Sierra Counties, looked at water quality during the immediate aftermath of the Camp Fire. Her results were also unremarkable. Read more here.

The take-home message from our forages study (which I think also applies to water quality) is this:

"While more detailed and controlled studies could provide additional information, these results indicate that forages affected by wildfire ash deposition are likely safe for livestock to consume.

"If you have forages that may be affected by ash deposition, evaluate the concentrations of minerals before formulating a ration [or grazing pastures]. If you're exceptionally concerned about toxicity from contamination and cannot dilute with unaffected feed, isolate and test feed for heavy metals and organic compounds."

I've been fortunate to have the opportunity to get a fair bit of formal education - from my undergraduate days at UC Davis studying agricultural economics to the online coursework I took while obtaining my master's degree at Colorado State University. The certificates that hang on the wall in my office attest to this formal education; my membership in professional societies (like the Society for Range Management and Western Association of Agricultural Economics) gives me access to continued learning. My formal (and continuing) education has driven my intellectual curiosity.

Thankfully, I've also had the opportunity to learn from experience - my own and that of others. Much of what I've learned through my own experiences has been from mistakes that I've made! In many cases, I've learned what NOT to do next time. I've also had the good fortune to learn from others - from mentors (ranchers and colleagues). This informal learning is interesting - while there are times when it confirms what I've learned from books or in classrooms, it often makes me question my formal instruction. And it certainly drives my intellectual curiosity, as well.

Early on during our shelter-at-home experience this spring, my friend Ryan Mahoney, a sheep producer from Rio Vista, approached me with the idea of starting a podcast about sheep production. While Ryan operates at a very large scale (and we have a much smaller operation), we felt like we could both learn from one another. We also felt like taping a podcast would give us something to do every Wednesday afternoon! And so Sheep Stuff Ewe Should Know was born! We've now produced 12 episodes in our first season, covering topics like risk management, the effects of COVID-19 on the sheep industry, and livestock guardian dogs.

Of all the topics we've discussed, though, I think I learned the most from this week's episode. On Wednesday, we interviewed Ryan's grandfather, Richard Emigh, who will turn 91 this summer. Mr. Emigh recounted his lifelong experience in the sheep business - after an hour long conversation, I felt we'd just scratched the surface! He talked about what makes good sheep range, about the value of multi-species grazing (he ran cows and sheep together), and about the need to be creative in today's sheep industry. Personally, my favorite part of the conversation was our discussion about the importance of experience and local knowledge - Mr. Emigh talked about how a good sheepherder knows what his (or her) sheep need to eat at that moment, telling us:

"The best sheepherder gets the most out of the land by getting the most into the sheep." 

As we continue producing Sheep Stuff Ewe Should Know, Ryan and I hope to interview other producers to learn from their experiences. We'll also be talking with experts in animal health, livestock nutrition, marketing, and business management - learning from their experiences, and having fun along the way!

Given California's ongoing shelter at home order, in response to the COVID-19 crisis, most of the ranchers I know are no longer gathering at a local coffee shop to catch up on how the neighbor's calf crop looks! Thanks to the wonders of modern technology, however, I held my first-ever Virtual Coffee Hour for ranchers this morning! We had a great discussion about drought, wildfire preparation, the impacts of COVID-19, and our individual coffee preferences.

Our conversation confirmed that this has been an exceptionally unusual year in terms of forage growth. Some noted that there seemed to be more foxtail and filaree than usual; others said the forage growth was patchy. Everyone felt like the forage on our annual grasslands would mature earlier than usual - possibly signaling an early onset of fire season.

Most importantly, we learned that 60 percent of those on the call prefer black coffee, while 30 percent add cream and sugar. And an astounding 10 percent didn't drink coffee at all!

Our next Ranchers Virtual Coffee Hour will be on Tuesday, May 5 at 6:30 a.m. - register here to get a link:

Last Saturday evening, the Tahoe Cattlemen's Association held it's annual membership dinner. Ranchers from Placer and Nevada Counties sat down to a wonderful tri-tip dinner prepared by the Del Oro High School FFA chapter. But despite the great meal and the enjoyable company, many were understandably concerned about the lack of rainfall. And as with any gathering of ranchers in Northern California this November, drought has begun creeping back into conversations here in the Sierra Foothills. When I jokingly asked who could remember the last time it had rained this fall, there was nervous laughter.

For rangeland livestock producers, drought is a different phenomenon than it is for crop farmers or urban dwellers; the dry spell we've experienced over the last month-and-a-half is no exception. Those of us who graze livestock on annual rangelands in Northern California rely on fall precipitation to germinate our fall/winter forage, and to replenish stock ponds and seasonal creeks for stock water.

This year, some parts of the Sierra foothills received a germinating rain in mid/late September. We actually had green grass on some of the annual rangelands where we graze our sheep near Auburn. Unfortunately, since October 1, we've measured just 0.02 inches of rain here at the UCCE office in Auburn. The warm temperatures and dry north winds we had in October pulled moisture out of the soil; the grass that got started in September has mostly died. PG&E's public safety power shutoffs and an unusually abrupt end to irrigation water deliveries in Placer and Nevada Counties have left many ranchers scrambling to provide drinking water to their livestock.

I find that the drier the autumn weather, the more frequently I check the weather apps on my phone. As I write this today, there is no rain in our forecast through November 22. Daniel Swain, who writes the California Weather Blog, suggests that we may finally see some wet weather in Northern California at the end of November. The long-range outlook from the National Weather Service, however, remains bleak - a 40 percent chance of below average rainfall in California through January.

While these forecasts can be depressing, I also know that conditions can change rapidly (and counter to what the weather experts predict). From October 2013 through the end of January 2014, for example, we measured less than 4 inches of rain in Auburn; in February 2014, we received almost 9 inches! More recently, in December 2017 we

received less than an inch of rain; the next month brought more than 7 inches (and 2018 forage production set records in the foothills). From a practical standpoint, perhaps the best drought strategy is to hope for the best, but plan for the worst!

Given the lack of green forage on our annual rangelands at the moment, and the lack of stormy weather on the horizon, what does planning for the worst look like? What actions should we be taking now to reduce the impact of both short-term and long-term drought?

Develop a Forage Budget: Most of us stock our grazing land conservatively - we try to manage our grazing during the spring and summer months to make sure we have fall feed. But do you know how much feed you actually have this fall? Do you know how many days of grazing you have before your fall feed is gone? Since the 2013-14 drought year, we've kept track of our forage supply and demand (or carrying capacity and stocking rate). Rather than use the standard unit of an Animal Unit Month (or AUM, the amount of forage consumed by a 1000-lb cow and her calf in one month), we track sheep days per acre. Granted this measurement is very specific to OUR sheep, but it gives us a useful estimate of our specific supply and demand. In the last two weeks, we've analyzed our winter pastures and determined that without forage growth, and with our current sheep inventory, we'll run out of feed in mid/late January. This is not a happy discovery, obviously, but it does help us focus on our options for addressing this shortfall.

Increase Forage Supply: You may have heard the adage, "Don't feed your way out of a drought" - you may have even heard it from me! And while feeding hay quickly becomes prohibitively expensive, there may be other ways to increase forage supply. In our case this fall, a friend offered us 40 acres of alfalfa stubble for the sheep. Instead of moving to our winter pastures this weekend, we'll save that forage for late December. Other options might be talking with a neighbor about an ungrazed property, or even hauling stockwater to an under-utilized portion of your own ranch. Obviously economics come into play here, too - is hauling water or building fence more expensive than feeding hay? That question will be answered differently for every operation!

Decrease Forage Demand: Selling animals is never an easy decision. One of the most difficult days in the 15 years we've raised sheep commercially was the day in January 2014 when I sorted off bred ewes to haul to the auction - we were out of forage and weren't sure when it would rain again. That said, giving some thought to the animals you could sell - or those you'd keep at all costs - helps make that decision easier. This year, we've prioritized the following animals for sale if the dry weather persists:

1. Open/cull ewes
2. Older rams
3. Excess feeder lambs
4. Replacement ewe lambs
5. Old/thin bred ewes

Given the cost of hauling sheep to the auction, we want to make sure we have more than one or two; that said, when the sheep come off the alfalfa next month, the cull ewes, older rams, and excess feeder lambs will be sold. We'll save forage for the bred ewes and the replacement ewe lambs.

Selling breeding females is a more difficult decision for us. We can't simply go to the auction when it starts to rain and purchase bred ewes that fit our system and our forage resources; indeed, we're still recovering from selling sheep in 2014. And selling an asset (a ewe lamb or a heifer, for example) means we forego the future income she'd produce. We need to compare the money we'll save in the short term (by not having to buy feed) with the income we'll lose by selling breeding animals. There are a number of more sophisticated economic analysis tools we can use to consider these types of decisions.

Develop Stock Water Infrastructure: Fall stock water is often a limiting factor for many rangeland operations. If ponds haven't filled and creeks aren't running, pastures can't be grazed. While long term solutions (like drilling wells or installing water tanks and troughs) may be expensive and time consuming, short term solutions (like hauling water) may allow us to access additional forage resources. For example, in the winter of 2014-2015, I managed the cattle at the UC Sierra Foothill Research and Extension Center in Browns Valley. As you might recall, that winter was also exceptionally dry. In January, we realized we had more than 20 acres of grass growing along the road system on part of the facility - grass that was outside of our pastures. By hauling water to portable troughs placed on the road, we were able to graze this otherwise unusable forage. And we were able to give the regular pastures a much-needed rest. Hauling water, in other words, bought us time (and forage).

Because ranches are also businesses, we need to consider the financial, economic, and tax consequences of our drought strategies, as well. The UC Rangelands Drought Information Hub has a number of outstanding resources on these topics, as well as links to long-range forecasts. And I'm happy to help you walk through these considerations on your own operation - we can develop a forage budget, talk about water development, and discuss other drought management strategies. In the meantime, remember that staring at your weather app and cursing the weather forecast (as I have done) are not effective drought strategies!
