Late last month, we held a Prescribed Fire on Working Landscapes workshop near Colfax, culminating in a small broadcast burn on the Edwards Family Tree Farm. As we prepared to ignite the burn, our instructor emphasized that the dry winter and early spring had resulted in fire conditions that were more like early June than late March. Last night, after I finished working in the office, I decided to try to burn some brush at our home place near Auburn. The message on the Placer County Burn Information line indicated that burning was suspended through tomorrow due to elevated fire danger. In early April. I guess it's time to start preparing our ranches for another fire season.
Wildfire preparations can more complicated for commercial livestock operations than for typical homeowners. In addition to creating a fire-safe space around homes, we also need to protect livestock and ranch infrastructure. Many ranches have livestock in multiple locations, and many of these leased pastures are simply pastures; there is no landlord or caretaker on site. Often, the number of livestock at a particular location may be more than can be easily evacuated in case of wildfire. Finally, access during a fire may be difficult due to law enforcement road blocks and priority for fire equipment. Here are a few of things we do to get ready for fire season.
Assessing the Threat
What is at risk in our operation? Do we have livestock in multiple locations? What is access like? At a minimum, our wildfire preparation efforts address the following:
- Create defensible space around home(s), barns and other infrastructure.
- Are there any access issues at any location where you have livestock? Single lane roads can be especially problematic. Do you have alternative access points?
- If you rely on dry forage for fall grazing, are there steps you can take to protect this forage from fire?
- Are there potential animal health issues associated with smoke and other indirect wildfire impacts?
Developing and Implementing a Wildfire Plan
Our ranch wildfire plan has several components:
- Protecting buildings, infrastructure and information: We remove flammable vegetation from within 100 feet of houses and other buildings. This also includes other critical infrastructure like propane tanks, wells, equipment sheds, barns and corrals. We also make sure we have protected critical legal documents and insurance information. Check CalFire's suggestions for putting together an emergency supply kit (http://www.readyforwildfire.org/Emergency-Supply-Kit/).
- Protecting forage: Like many operations, we stock our rangeland pastures conservatively to ensure a supply of fall forage. In some areas, we try to create fuel breaks to protect this forage from wildfire through targeted grazing. Disking or grading around the perimeter of pastures, or at least adjacent to potential ignition sources, can also reduce the threat. The width of any fuel break depends on the fuel type, topography/slope, and potential flame lengths that a fire might generate.
- Protecting livestock: We try to plan ahead for how we might move livestock out of harm's way in the event of a wildfire. That said, we have too many animals to evacuate on short notice; leaving animals in pasture (or “sheltering in place”) might be our best option. Fortunately, we've never had to do this. If you need to leave animals in place, be sure they have enough feed and water for several days. Will the livestock have water if the power goes out? Be sure to take down temporary fences or other hazards that may injure livestock as the fire moves through the property. Prepare for any post-fire health problems (like respiratory infections or other injuries) as well.
- Water supply: Water is critical for protecting our properties and for keeping livestock healthy. Do you have adequate water supplies for wetting down your buildings and facilities, or for directly fighting fire? If you have to pump water, do you have a backup system in case you lose power? Can you provide stock water if the power goes out? You may want to consider investing in a backup generator and/or additional water storage.
- Escape routes: Ideally, we try to have at least two routes in and out of our ranch properties. In addition, we try to think about at least two alternatives for moving livestock to safety in the event of a fire - this means loading and unloading facilities, a plan for gathering livestock, and a clear understanding of the road system near your pastures. Narrow roads can be problematic for navigating with stock trailers, especially when fire equipment is also inbound.
- Backup: Obviously, many of us can't be on hand 24 hours a day, seven days a week to respond to a fast-moving fire (especially when livestock are grazing on multiple properties). We work with friends, neighbors or colleagues to have a backup plan to evacuate or otherwise protect your livestock. Consider meeting with your neighbors to go over key livestock facilities, evacuation plans and access routes. Be sure to check in with these backup resources in the event of fire.
- Communication plans: I try to keep phone numbers for the other ranchers in our area on my phone, and I try to keep track of who runs the cows or sheep next door. During fire season, many ranchers text or call neighbors when they see smoke. Consider formalizing these calling trees.
- Situational awareness: During fire season, I constantly watch for smoke, especially when I hear fire equipment or aircraft. We carry a shovel or other fire tool and 5 gallons of water in our pickups and pay attention to where ranch visitors park – a catalytic converter on dry grass can be disastrous. I also check local news websites or alert services (like www.yubanet.com).
Writing Down our Plan
Even for ranching operations with few or no employees, writing down our plan can help others (spouses, neighbors, etc.) know what to do and who to contact in case of fire. Our written plan includes the locations where livestock are grazing (which suggests this plan needs to be updated as livestock are moved). Location information includes a physical address and/or map, along with the number and class of animals on site. We also include a description of potential evacuation routes (including locations of loading facilities). Are there safe zones (like dry lots or irrigated pastures) on the property or nearby where animals could be moved if evacuation isn't possible? Is there an onsite caretaker or neighbor we can call in case of emergency? Are there other ranchers who could help us? What are the numbers of livestock haulers who might be available? Click here for a template for completing your own plan!
I share a copy of this plan with other people in our operation – specifically, with my wife and kids, and my partner. This year, I'll plan on sharing this plan with our landlords, as well. Finally, we'll provide a copy (or at least a list of locations where we have livestock) to our local fire, animal control, and law enforcement agencies.
A Future Solution?
As with many other ranching counties in California, Placer, Nevada, and Yuba Counties have been working on formalizing an Ag Pass program designed to help ranchers gain safe access to livestock in emergency situations. Assembly Member Megan Dahle has introduced legislation (AB 1103) that would implement this program statewide. These programs would require ranchers to attend training on fire behavior and the incident command system, and would likely also require a list of properties where livestock may be grazing. If you'd like more information about the Ag Pass idea, contact me at dmacon@ucanr.edu.
As I look back over previous posts to my Ranching in the Sierra Foothills blog, I see that I seem to write about wildfire preparation just about every spring. I guess that's the nature of living with fire - our ranch fire plans are something that we should revisit every year - better to have a plan that we don't use than to need a plan when fire strikes. Stay safe this summer!

Lessons from our first Prescribed Fire on Working Landscapes Workshop
As I wrote in a blog post in February (Working with Fire), at one time, fire and fire agencies were part of the ranching culture of the foothill communities where I grew up. At some point, though, we lost the cultural affinity for – and know-how about – using fire as a tool for improving rangeland conditions and preventing larger, catastrophic wildfires. Fire became the domain of professionals – we simply couldn't trust "civilians" with such a potentially dangerous tool. When I graduated from college and started my career in the early 1990s, very few ranchers were using fire in the foothills.
Last week, we held a Prescribed Fire on Working Landscapes workshop at Edwards Family Tree Farm in Colfax. Nearly 30 ranchers, forest landowners, agency staff, and NGO staff joined us for two days of learning about – and actually using – fire to manage fuel loading. During our introductory webinar the evening before the first field day, my colleague Jeff Stackhouse, from Humboldt County, encouraged us to embrace "cowboy burning." The next morning, our host landowner Allen Edwards told me, “Dan, try to shepherd that fire down to the next check line.” Jeff and Allen made me realize that using prescribed fire, in many ways, is very similar to low-stress livestock handling. This might seem like a stretch, but let me explain!
- Communication is critical! Before we struck the first match, our workshop leader (Chris Paulus, a retired CalFire battalion chief and prescribed fire practitioner) led us in a pre-burn briefing. We discussed our burn plan, our safety measures, and what role each of us would play during the burn. We continued communicating during the burn, and Chris ended the workshop with a post-burn debriefing. Similarly, when we're moving sheep at the ranch – or working cattle at someone's ranch, we try to talk through our plan (even if it's simple) before we get started. Outlining expectations – and what to do when plans change – is vitally important! And we also talk when we're done - identifying the things that worked (and more importantly, the things that didn't) make us better prepared the next time.
- Don't force it – observe behavior and respond as appropriate. My predecessor Roger Ingram, who had a chance to work with legendary stockman Bud Williams, says this about our attitude when working stock:
Old Attitude: “I'm going to MAKE that animal do what I want.”
New Attitude: “I'm going to LET that animal do what I want.”
This shift in attitude requires careful observation of livestock behavior – if we pay attention, the animals will tell us when they're comfortable – and when they're stressed!
Chris taught us to pay attention to what the fire was telling us. A subtle shift in the wind, or a change in fuel type or dryness, changed fire behavior. Chris and Allen prepared the burn unit to help account for these variations – pre-established check lines and the strategic application of just a little water, for example, helped us LET the fire consume the fuels we wanted to impact while protecting the trees we wanted to save.
- Movement is good! When I first started riding horses or training sheep dogs, my natural tendency when things started moving too fast was to shut down all movement. A standing horse couldn't buck me off; a dog in a lie down wouldn't chase the sheep. As I gained more experience, though, I realized that we all made progress (me, dogs, and horses alike) when we were moving. I could begin to shape behaviors and improve communication by working through those times when we were all responding to one another.
My entire previous experience with prescribed fire was with pile burning – where movement of fire is undesirable! Last week, I learned about broadcast burning – about how to keep fire moving across the landscape safely. Chris and Allen showed us how to use simple techniques, like moving fire with a pitchfork and burning pine needles. By burning down-slope and into the wind (a backing fire), we were able to keep fire safely moving through the acre-plus demonstration site.
- Never stop learning! As I've gained more experience in handling livestock (and working my border collies), I've realized how much I don't know. Stockmanship, I think, requires a lifetime of observing and learning. Getting my first hands-on experience last week with broadcast burning was similar; I am realizing how much more there is to know about fuel types, burn conditions, terrain and topography, timing, etc. – we barely scratched the surface. Like stockmanship, prescribed fire requires both an intellectual understanding of the tool AND hands-on experience in a variety of settings.
Most importantly, last week's burn seemed simple, thanks to Chris and Allen. Most of us who were on site wore cotton or wool work clothes, sturdy boots, and work gloves. We had a variety of hand and power tools (fire rakes, McLeod hoes, pitchforks, backpack pumps, chainsaws, and leaf blowers), plus a pick-up bed water tank and trash pump for extra water. Chris brought a unique combination of professional knowledge and landowner practicality to the burn. While Chris is definitely an advocate for “good” fire, he's also sympathetic to the concerns and questions that landowners have about returning fire to the tool box. I'm looking forward to learning more!

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 |
1700 gal |
Total Water Demand/Month |
51,000 gal |
Water Truck Capacity |
3400 gal |
Loads of Water / Month |
15 |
Cost/Load |
$350 |
Cost/Month |
$5,250 |
Cost/AUM |
$53 |
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).

I've known Doug Joses and his family for more than a quarter century. The unofficial mayor of Mountain Ranch (in Calaveras County) Doug has spent his entire life ranching in the Sierra foothills – raising cattle, sheep, and Angora goats. Several years ago, Doug related his experience during the Butte Fire (which devastated portions of Amador and Calaveras Counties in 2015). He also talked about his experience using fire to improve rangeland productivity in the 1970s and 1980s – he and his neighbors used fire regularly to control brush and improve forage quality for livestock and wildlife. I wasn't old enough to realize it, but fire was part of the ranching culture of the foothill communities where I grew up.
At some point, though, we lost the cultural affinity for – and know-how about – using fire as a tool for preventing larger, catastrophic wildfires (and for improving rangeland conditions). Fire became the domain of professionals – we simply couldn't trust ranchers – or our communities, really – with such a potentially dangerous tool. When I graduated from college and started my career in the early 1990s, very few ranchers were using fire in the foothills.
Perhaps landowners need to “take back” the work of using fire. Last month, I had the opportunity to observe (I would like to say “help,” but I really didn't do very much) a small broadcast burn in a patch of nonindustrial timber land near Colfax. The 2-acre site was part of a larger, multi-landowner shaded fuelbreak that included portions of Allen Edward's property. This particular patch had been masticated to knock down the brush that had regrown after the 2001 Ponderosa Fire (which Allen's previous fuel reduction work had helped to stop).
Of the various methods for reducing fuel loads, only fire and grazing actually remove fuel – mastication, mowing, herbicide treatments, etc. modify the fuel profile, but the fuel itself remains in place. The wood chips and brush scraps leftover from the mastication on this site were still flammable.
The key takeaway for me from the burn at Allen's was that fire – like grazing – can be an iterative process. A single burn – like a single graze period – won't necessarily convert a fire-prone site to a fire-safe site. Last week's burn consumed fuel on the surface, but not the deeper material that had been moistened by previous rainfall. Allen also emphasizes that two-thirds to three-quarters of the cost of the burns he's conducted so far were incurred “before we ever struck a match,” adding, “without the mastication, hand clearing, and pruning, a fire would destroy most of my trees.”
Most importantly, last month's burn seemed simple. All of us who were on site wore cotton or wool work clothes, sturdy boots, and work gloves. We had a variety of hand and power tools (fire rakes, McLeod hoes, pitch forks, backpack pumps, chainsaws, and leaf blowers), plus a pick-up bed water tank and trash pump for extra water. Chris Paulus, a retired CalFire battalion chief who is leading this effort in Colfax, brought a unique combination of professional knowledge and landowner practicality to the burn. While Chris is definitely an advocate for “good” fire, he's also sympathetic to the concerns and questions that landowners have about returning fire to the tool box.
As I've talked with Allen and Chris, a new idea is forming. Like any new “tool,” landowners and managers need time to get comfortable with actually using fire on the landscape. We've used our 2-day grazing academies (started by my predecessor, Roger Ingram) as a way to help ranchers get comfortable with managed grazing systems. What about a prescribed fire academy, where landowners can get real-world experience using fire to reduce wildfire danger, improve forage production, and enhance wildlife habitat. Stay tuned!

15 years of experience with lameness in sheep
During the first half-decade we tried to raise sheep commercially, we battled a variety of foot issues. Seems like we had just about every problem a sheep producer could face - foot scald, foot rot, you name it. We trimmed feet 3-4 times a year. We tried foot baths of all sorts. We treated infected sheep with antibiotics and topical sprays. We vaccinated every ewe twice a year. And we culled any sheep that didn't respond to treatment or prevention.
Our experience with lameness mirrored that of most sheep producers who've dealt with the problems. Trimming 3-4 times a year was a significant labor expense. Treating sheep with antibiotics was expensive, too. Sheep that were limping simply didn't perform as well as sheep that weren't- which translated to lower reproductive rates and lighter lambs. Since we often had our sheep grazing along public roads, the public perceptions associated with limping sheep or sheep that are grazing on their knees was a persistent a constant problem, as well.
Fortunately, we kept decent records about the sheep we treated for lameness. When the 2014 drought forced us to sell ewes, chronic foot problems were among of our culling criteria. And since that time, our lameness issues have been greatly reduced. In the last seven years, we've only trimmed feet during our pre-lambing vaccinations - just once a year.
This January, I invited our new UC Davis Sheep and Goat Extension Veterinarian, Dr. Rosie Busch, to join me on vaccination and foot trimming day (in a thinly veiled attempt to get some help!). Dr. Busch and I have been talking about putting together a video with the latest information on foot rot and food scald, and we thought this would be a good chance to get some real-world photos and video footage. In anticipation of our work day, she searched the literature for the most current approach to managing foot health.
Dr. Busch took the time to explain the various causes of lameness - knowing what we're dealing with is critical to developing a treatment plan. The information below is adapted from the Veterinary Ireland Journal.
- Foot Scald: Symptoms include moist, painful inflammation of skin between the digits. No lifting of hoof. In adult sheep, scald is often early foot rot and probably should be treated as such (see below). Antibiotic sprays or foot baths are sufficient treatments in lambs.
- Foot Rot: Starts between digits but progresses to under-run hoof. Foot rot has a distinctive smell. Infected sheep will spread infection. Chronic cases have misshapen hooves. Treat with injectable antibiotics and consider vaccinating the entire flock.
- Contagious ovine digital dermatitis (CODD): Very painful and invasive. Lesions start at top of hoof. Rapid spread to under-run hoof wall. Treat with injectable antibiotic and antibiotic spray together. Antibiotic foot baths are another treatment option.
You might notice that foot trimming doesn't appear on the list of treatments. In fact, the journal article says,
"Foot trimming was long recognised as an appropriate management technique for sheep until considerable research suggested that routine trimming can increase levels of lameness. More recently, it was shown that even trimming the hooves of lame sheep may lengthen the time it takes for them to heal."
All of which brings me back to our experience this year. I had started to reduce the amount of trimming we were doing last year. With Dr. Busch's direction, we trimmed feet on just 9 ewes out of the 115 that came through the corrals this year. We found no active foot rot; rather, we trimmed any feet that had conformation problems. We also recorded the ear tag numbers of each ewe that was trimmed. In at least one case, the ewe's foot conformation was so bad that we marked her to cull when we wean our lambs. The other ewes who were trimmed will be tracked in subsequent years. Foot health, it seems, is actually better when we do less!
Watch for our video in the next several months!
