With wildfire season in full swing in California and elsewhere in the West, many ranchers are increasingly concerned about the safety and well-being of their livestock. Many - if not most - commercial-scale producers in the Sierra foothills and higher elevations operate on multiple parcels with multiple landowners. Accessing livestock in an area under evacuation orders due to wildfire - or any other large-scale disaster, for that matter - can be problematic. Commercial-scale operations typically have more animals than can be evacuated in a single load, making sheltering-in-place the only viable option. But livestock that are sheltered-in-place need care - water, feed, medical attention, etc. - making access for ranchers critical.
Over the last 6 months, I've been working with a committee of ranchers from Placer, Nevada, and Yuba Counties, along with the Agricultural Commissioners from each county, to create a Disaster Livestock Access Pass Program. The geographic focus of this effort mirrors CalFire's administrative region - and reflects the on-the-ground reality that many ranching operations cross county boundaries. We've patterned our local program on similar efforts in Butte, Santa Barbara, and San Luis Obispo Counties. We hope to develop a similar program for Sutter County in the coming months.
For the purposes of this program, a commercial livestock operator is defined as an owner of livestock consisting of 50 head of livestock (including in utero, e.g., 25 bred cows), 100 poultry or rabbits, or 50 beehives or more that reside in Placer, Nevada, or Yuba County for at least a portion of the year, or a person who, through an agreement with that owner of livestock, has authority and is responsible to oversee the care and well-being of the owner's livestock.
To receive a Livestock Access Pass, qualified producers must complete an application survey and attend a 4-hour training session which will include information on fire behavior, the incident command system, and ranch-scale fire preparations. We will be holding training sessions in Auburn, Browns Valley, and Nevada City.
I've prepared a comprehensive Producer Information Packet, which is available on my website. If you'd like me to email you a packet, please contact me at dmacon@ucanr.edu.

Short- and Long-term Stock Water Strategies
On a day that started with a long-overdue rainstorm here in Auburn, I received word that USDA Secretary Tom Vilsack had declared a drought disaster in 50 of California's 58 counties – including Placer, Nevada, Sutter, and Yuba. The announcement doesn't come as a huge surprise for anyone who's been grazing livestock on annual rangelands this winter, but the official designation does come with the possibility of emergency assistance through the Farm Service Agency (click here for a directory of local FSA offices).
While ranch drought management is fundamentally about creating flexibility to balance demand (that is, the number mouths we have grazing) with supply (the amount of grass we have available), my own experience suggests that drought presents a complicated set of problems. Our forage demand changes with our production calendar – the lactating ewes we're grazing today need more forage than they did back in November. And quantity isn't the only variable that concerns us – lactating ewes also need high quality forage from a nutritional standpoint. Drought can impact both.
Drought impacts, then, are more complicated that below-average rainfall, obviously. Rain and forage production are related, but on our annual rangelands, the timing of the rain is nearly as important as the quantity. We'll likely end up with an inch of rain out of the series of storms we've enjoyed this week – enough to keep our grass growing.
As I was moving sheep this morning, however, I checked the small seasonal creek that runs through several of our winter pastures. It hasn't flowed all winter, and this most recent shot of rain wasn't enough to get it started. Talking to ranchers throughout my four counties, I would say that the soil profile never really filled enough to get the creeks running – or the stock-ponds filling – anywhere in the foothills. Operations that saved dry feed for the fall couldn't access some of it for lack of stock water. Now that the grass is growing, some ranches still don't have enough stock water to use the forage.
With sheep, we're used to hauling drinking water – even on large scale operations. Most cattle producers don't have the equipment to move water to their livestock, however – the quantities required, and the remoteness of some operations, can make this difficult. I spoke to a water truck operator this morning who said he's starting to get calls from foothill ranchers about hauling stock water – a sure sign that conditions are extremely dry. This particular owner-operator can move 3,400 gallons at a time – and he charges $100 per hour plus the cost of the water (for example, a single load of water delivered to Lincoln would cost around $350).
How long would a load of water last? Obviously, stock water demand depends on air temperature, stage of production, and even hide color. Developing a water budget based on stage of production and air temperature can help provide a more accurate estimate of stock water demand for a specific group of cattle (see the chart below).

Is hauling water worth the expense? If you've saved forage – or if you have spring forage that you can't use for lack of stock water, it's worth putting pencil to paper. Based on the costs outlined above, here's an estimate of the cost of hauling enough water for 100 pairs on springtime annual rangeland in the Lincoln area - it's not cheap!
Number of Cattle (cow-calf pairs) |
100 |
Water Demand/Animal Unit/Day |
17 gal |
Total Water Demand/Day |

Total Water Demand/Month |
51,000 gal |

Loads of Water / Month |
15 |
Cost/Load |
$350 |
Cost/Month |
$5,250 |
Cost/AUM |

Assumptions
- Water hauling charges are $100/hour plus the cost of the water
- The haul for this example is from Auburn to Lincoln, with water purchased in Wheatland
- Cattle are grazing springtime annual rangeland
- Average daily high temperatures are 70-80F
From a longer term perspective, developing alternative stock water supplies and storage systems is critical for drought flexibility. The Natural Resources Conservation Service can provide technical assistance and perhaps even cost-share funding to help pay for these types of projects (click here for a directory of local NRCS offices).

Here in Auburn (on December 17, 2020), we received 0.64" of rain overnight. After a late start to the rainy season (and to germination on our annual rangelands), any rain is welcome at this point. But last night's rain continues an interesting (and potentially troubling) trend - our storm total was about 60 percent of what forecasters predicted earlier in the week. Similarly, last weekend's storms delivered less moisture than predicted. Our seasonal total (since October 1) is just over 4 inches; our average seasonal total here in Auburn over the last 20 years is over 11.5 inches - in other words, we've received just 36 percent of our "normal" precipitation so far.
On the positive side of all of these numbers, we have received enough rain to keep the grass that germinated last month going for a month or more. For our small sheep operation, we'd established a key date of December 31 for implementing more drastic drought measures (like buying more hay or selling sheep). With 1.89 inches of rain this month, and with the forage we've saved due to our conservative stocking rate and diligent grazing planning, we should make it through lambing without much added expense.
But the pattern remains concerning. I've noticed over the last several years that precipitation forecasting has become more accurate. While the exact timing of storms remains difficult to predict with down-to-the-minute accuracy, forecasters have become more adept at predicting storm totals several days out. That this year's storms seem to be falling short of predictions suggests that forecasting remains an inexact science.
Obviously, rainfall on our annual rangelands does more than grow forage. Many operations rely on run-off to recharge seasonal creeks and refill stock ponds. Without stock water, some producers won't be able to use the forage they saved from last spring (or they'll need to haul water). In the medium-term, the lack of snowfall in the high country portends a challenging summer for those of us who rely on irrigated pasture. Fortunately, our local water districts entered the winter with adequate carry-over in their reservoirs, but a lower-than-average snow pack is definitely concerning!
So while while our operation has made it through the first critical date of our drought plans, we're not out of the woods yet. After lambing is over in late March, our next major decision point will be weaning. We usually wean the lambs in mid/late June - sometimes as late as early July. In order to save forage on our annual rangeland for next fall, we may wean and sell our lambs early, allowing us to graze dry ewes on irrigated pasture into midsummer (which reduces our forage demand). I suspect our next decision date will be sometime in mid/late April.
I won't reiterate how difficult 2020 has been on a variety of fronts - drought just seems like one more crisis on top of a crisis-dominated year. I would encourage you to check out the Rangeland Drought Information Hub on the UC Rangelands website, however. You'll find a variety of resources for responding to drought conditions. From my perspective, the best time to start planning for drought is while it's raining. The second best time to start planning for drought is now!

In the meantime, how are you going to cope?
Having lived (and ranched) through California's 1000-year drought from 2012-2015, I often find myself recalling the autumn of 2013. Believe it or not, we had a germinating rain on September 3 - I measured 0.75" of rain here in Auburn. Just under three weeks later, we received another inch of rain. The combination was enough to get our grass started! But a fellow rancher - I can't remember who - told me never to trust a grass year that started before Halloween. October turned dry and November turned cold and dry - between October 1 and December 31, we measured just over two inches of rain. The grass that had looked so promising in late September was gone by New Year's Day 2014. My rancher friend was correct.
The Sierra Foothills typically experience a prolonged dry spell from late spring through early fall - part of living in a Mediterranean climate. Every autumn, I look forward to the first germinating rain - the storm that is the dividing line between brown grass and green grass on our annual rangelands. Weather forecasts from two weeks ago suggested that we'd get this storm last weekend; reality proved otherwise, and our weekend was cool but dry. And the most recent California drought map indicates that our normal dry spell has intensified into moderate-to-severe drought.
Looking back at 35 years of monitoring data from the UC Sierra Foothill Research and Extension Center (SFREC) in Browns Valley, I see a record of uncertainty and variability. The earliest germinating rain at SFREC was recorded on September 2, 2000. The latest occurred just two years later, on December 12, 2002. Over the last 35 years, the first germinating rain of the fall occurred around October 21. But in 29% of the last 35 years, a germinating rain hasn't arrived until after November 1.
Why does this matter? As most ranchers will know, we usually reach a point in mid-December when the days are too short and the temperatures (both air and soil) are too cool to support grass growth, regardless of soil moisture. I call this our winter dormant period - the timeframe where we have to get buy on the grass that grew from germination to dormancy (and last year's dry grass). If germination happens in mid-October, and we get follow-up rains, this means we have 45 days worth of growth at least. If germination happens a month later, we don't have much grass.
Because of this uncertainty and variability, most of us are conservative in our stocking rates - we keep the number of breeding animals we know we can sustain through a dry fall. Many of us use supplemental protein to be able to utilize the dry forage we saved from the previous spring. Others try to match our production cycle to the forage cycle, calving or lambing when we're likely to have adequate high quality forage.
As I think back on my experiences in 2013-2014, I think there is a difference between short-term drought and long-term drought. Our preparation strategies, like a conservative stocking rate and fitting our production calendar to the forage, help us deal with both. Response strategies, however, can be ramped up as the severity of the drought escalates. Buying supplemental feed, for example, might help bridge a dry fall; buying replacement feed to get through a dry two or three years is a recipe for bankruptcy. Similarly, deciding not to buy in stockers or feeder lambs in a dry fall is a short-term solution; selling breeding animals or replacement females is a more drastic step that might be necessary in a long-term drought.
One of the most important lessons I learned in the last drought is that we constantly need to be thinking about how much forage we have ahead of us, and talking about key decision dates. At the moment, we have enough dry grass to get through the end of January (provided we give the sheep supplemental protein). At that point, our ewes will be entering the last third of their gestation period - and their nutritional demands will start ramping up. We typically give the ewes their pre-lambing vaccines during the third week of January. If we're still dry at that stage, we'll have some difficult decisions to make. In the meantime, I'll keep doing my rain (and germination) dance! Don't worry - I won't post video!

Like many of you over the last several weeks (and indeed, over the last several years), I've read heartbreaking accounts of ranchers losing livestock in this latest round of devastating wildfires. I've talked to neighboring ranchers who helped friends evacuate livestock, and who moved their own animals to safe zones. And I've constantly watched the horizon for new smoke, and the sky for fire planes and helicopters. I've wondered what we can do as a ranching community to address our unique concerns and needs in the face of increasingly dangerous wildfires.
According to the California Fire Safe Council,
“Fire Safe Councils are grassroots, community-led organizations that mobilize residents to protect their homes, communities, and environments from catastrophic wildfire. A local Fire Safe Council is often sparked by a catalyst – perhaps a recent fire or a group of neighbors eager to spread a fire-safe message – then embraced by the community, which turns that initial interest into a committed group that finds ways to empower the residents to do their part to make the community safe.”
Most of these local Fire Safe Councils are formed by geographically related communities – counties, towns, or neighborhoods. But what about communities of interest? What about the ranching community? Our needs, when it comes to preventing and responding to wildfire, can be very different than a residential homeowner's needs.
Ranching in the Sierra foothills is unique. Many of us operate on multiple parcels, some leased, others owned. These ranches are dispersed throughout the community – they may be surrounded by residential communities or public lands. Some of us still take livestock to the high country, while others rely on irrigated pasture during the summer months. Many of us have livestock at multiple locations.
Because these ranches are grazed (or in fire terms, because the fine and ladder fuels are modified), ranches may provide areas where fire behavior changes – where firefighters can attack a fire directly. Ranches that include irrigated pasture may provide additional firebreak benefits. Some ranches have ponds or other water sources that maybe helpful to firefighting efforts.
Rancher needs during a wildfire may also differ from the surrounding communities. Unlike backyard livestock owners, commercial ranchers often have more livestock than can be evacuated by a single truck and trailer – making evacuation difficult even with enough warning. Ranchers with leased pasture may have difficulty accessing property and livestock during an emergency due to roadblocks. And ranchers typically have first-hand, on-the-ground knowledge – and oftentimes equipment – that may be helpful in the initial response to wildfire.
All of this brings me to an idea:
What if we created a Rancher's Fire Safe Council?
What if we formalized our efforts to inventory the equipment and expertise that could help protect ranch lands and the surrounding community? What if we formalized our relationships with CalFire, law enforcement, and other emergency services? What if we could train ourselves (and our neighbors) on things like safe evacuation and fire behavior? What if we formally became a resource for protecting our ranches and our communities?
I'd like to invite you to a meeting to explore this idea in more detail. And please feel free to invite other ranchers to participate. I envision this group being comprised of commercial producers – ranchers who have more livestock than could be evacuated in a single trailer, who are raising livestock as a business.
