Wolf Mitigation Budgets

Abstract

Wolf conflicts with livestock can be devastating for ranchers. Researchers, ranchers, state and Federal officials, NGO’s and others have worked hard to develop non-lethal mitigation practices that can reduce conflicts, thus allowing more harmonious coexistence. However, almost nothing has been published about the expected costs to apply these practices across varying landscapes. Costs vary substantially across terrains, ecosystems, climatic zones and ranch settings. To that end, we created an Excel tool to allow producers to develop customized enterprise budgets for turbo fladry, mortality management, ranger riders, guard dogs, and night penning. In addition, all of these cost budgets start with a representative example. We present the representative examples here and discuss how any individual might adjust those costs to reflect their own unique situations.

Gray wolves in their natural habitat

Introduction

Wolves sometimes target livestock as they hunt for food, leading to conflicts with ranchers. Finding ways to protect livestock is therefore essential as society seeks to enhance wolf populations in several U.S. states. Fortunately, by implementing effective deterrents, such as non-lethal predator control methods, proper fencing, and herd management strategies, producers can reduce losses while minimizing use of lethal control. There are several effective non-lethal and proactive strategies to help prevent wolves from killing livestock.

  • Physical barriers, such as reinforced fencing and fladry (flags attached to fences that deter wolves), can help keep wolves away from livestock.
  • The use of guard animals, especially dogs, but also including llamas and donkeys, can provide excellent protection particularly in large open landscapes.
  • Human presence, such as range riders who patrol grazing areas, also discourages wolves from approaching herds.
  • Additionally, noise-making devices, lights, and other scare tactics can serve as temporary deterrents.
  • Modifying grazing practices by keeping livestock in closer, well-monitored groups can help reduce risk.
  • Removing livestock carcasses, particularly from areas with other livestock that might attract predators, can further reduce the risk of wolf attacks.

By using or combining these methods, ranchers can reduce conflicts while promoting or tolerating coexistence with wolves.

Many U.S. states with wolves provide financial and technical help for ranchers that includes non-lethal prevention. There are several good publications with detailed descriptions, such as (Oregon Department of Fish and Wildlife, 2022; Lance, Primm, & Inman, 2023; Stone, S. A., 2016). Examples can be found throughout this publication, especially in the Appendix.

Despite several good publications about these practices, there is little published about what they cost. Knowing about potential practice costs could be valuable for those considering adopting them or to those wishing to provide financial assistance for their adoption. Producers can use this information to compare different systems that they want to consider and to evaluate whether they are worth their cost compared to the savings provided through a reduction in livestock losses.

We prepared this document to provide information about current costs to adopt a variety of non-lethal practices, including turbo fladry, electrified night penning, carcass removal, range riding, livestock guardian dogs and deterrents. Of course, costs vary substantially depending on the size of the operation, local laws, labor rates and availability, building materials, and other factors. To help better target estimates, we provide free access to an Excel file where anyone can tailor the information to represent their own unique circumstances (Excel file A).

Users may also want to consider making adjustments directly from values printed in this report without using the Excel file. Advice for making adjustments and references and links to other documents with more information are provided in the Appendix.

Enterprise Budgets

On the following pages we provide enterprise budgets with cost estimates for each practice.  We support these budgets with detailed information and notes in the Appendix.  Since everyone’s situations are different, we also offer information to help users make adjustments that customize costs to meet their own unique needs. We found that many circumstances can affect costs, but in most cases, a user will know whether they apply to their situation. For example, some producers may want to account for an increase in the cost of maintaining electric fence or fladry if they need extra labor because of deep snow or difficult terrain.

To account for annualized costs, each budget utilizes a “useful life” to incorporate practices that use materials that can be reused from year to year. The process to annualize these costs is amortization in which a lump sum value is portioned into yearly amounts based on the item’s useful life, the interest rate, and the original cost (much like a mortgage to pay interest and principal over a given amount of time). In the case of these budgets, a standard interest rate of 4% is assumed, however, this can be adjusted in the excel file.

Turbo Fladry

Turbo fladry is a practice that employs a string of nylon flags that are incorporated into electric wire. Wolves are considered neophobic animals, which means they fear things that are unfamiliar. The waving of the bright flags in the wind discourages wolves from approaching the area surrounded by fladry. For turbo fladry to remain effective and wolves to not become habituated to the flagging, experts advise that fladry should not be used for more than a couple of months at a time and only on smaller pieces of property like calving or lambing pastures. The budgets below are for Turbo Fladry. Fladry without electrification (not shown) can save money but is thought to be less effective.

Fladry and electrified fladry can be important tools for small areas, a few acres or less, and only for short periods of time (2 months or less). Weather events, especially wind and snow) can have a big influence on the effectiveness of fladry products by creating situations where sections of the fladry are either on the ground, covered or the flags coil around the holding wire. These situations create gaps and wolves will take advantage of gaps resulting in entry into protected areas as well as opportunities to overcome fear of the product. Therefore, regular maintenance of the fladry fence is very important and with big events may create significant efforts to repair and maintain the product.

**For the purposes of this enterprise budget, materials included will only be those that go directly into the electric fencing and that remain in the field, as well as labor costs. General equipment like gloves, voltmeter, post pounder, etc. that are likely to already be in the possession of a rancher or farmer are treated as fixed costs and excluded from the budget.

Night Penning Livestock

Another option for securing and protecting livestock is by night fencing/penning using various forms of temporary electro net or poly wire. This practice works by keeping livestock in a secure location surrounded by electrified fencing during the night when predation is most likely to occur. This practice can be used in conjunction with other practices such as fox lights, sound alarms or livestock guardian dogs. Guidelines for night penning are included in the “The Electric Fencing Producer Tool Kit” published by the Western Landowners Alliance (Collins et al., 2024) who supported the foundation of this budget sheet.

This document accounts for two different methods of approaching calculated annual costs. The first is the ‘Perimeter Method’ which asks directly how many feet of fencing a producer is interested in and calculates costs from there. The second method, the ‘Quantity of Sheep Method’, which asks the producer how many sheep they plan to pen and from there calculates how many feet of fencing would be required to fulfill the assumption that each sheep has their own 25 square feet of space.  We give equivalent examples below using both methods.  This method can also be used for cattle, but we only provide information for sheep.

The use of transitory night pens across open rangeland areas is not a common tool employed widely, thus there is not a lot of internal industry knowledge about how to best employ this strategy in a variety of situations. Thus, it is likely that producers that decide to employ this tool will have to be creative in when, where, and how this technique is used. For example, grazing that occurs in wilderness areas or other areas where vehicle use is prohibited, creates challenges for transport of materials through such landscapes. Training the livestock to do this practice is a critical endeavor to help optimize the effectiveness of this practice. Ideally training can occur early before livestock are allowed into remote grazing landscapes.

**Pen is assumed to be circular in shape but is often square.

Quantity of Sheep Method

The first method, shown above, asks producers their desired preference for perimeter length of electrified penning and the budget sheet will autofill based on that input. The second method asks a producer how many sheep they have in their flock and then assumes that each sheep should require 25 square feet of space. This was based on the reports of several individual ranchers and organizations that recommended 16-25 square feet per animal. However, this number can be adjusted based on the preference of the producer in the adjustment questions.

Range Riding

Range riding is a wolf-livestock conflict reduction practice that employs skilled riders to monitor livestock and predator interactions. Range riding involves increased human presence on rural rangelands by implementing consistent monitoring of predator presence, implements predator hazing when necessary and monitors the health and behavior of the herd to reinforce group resilience. Range riders can be current ranch operation owners or employees, or they can be contracted out from federal and state wildlife programs and other NGOs. The range riding season typically spans 6 months to coincide with the cattle grazing season from the beginning of May to the end of October, however this may alter slightly depending on the region and needs of the location.

Range riding is proving to be a popular tool for minimizing risk on large open range grazing systems. An important question surrounding the practice of range riding is whether the range riders focus on managing the livestock or managing the wolves. This is an important distinction because each strategy requires different skill sets. The reality is that an effective range rider will focus on both livestock and predator but how much time is spent on each endeavor will depend heavily on the goals of the producer, the context of the grazing scenario, and the abilities of the range rider. It is therefore important for those considering this practice to identify their priority and then find personnel well suited to those priorities.

**Factors used for these calculations can vary significantly. These include forest cover, terrain, range rider skills, carnivore activity, safety precautions, scope of rider duties, etc. Also, additional equipment, such as drones, can add costs.

Carcass Removal

A practice that involves separating a deceased carcass or bone pile from an active ranching operation and properly decomposing the remains so that they can be reused for fertilizer or further carcass composting. Livestock carcasses as well as aged bone piles can act as an attractant for predators such as wolves. Thus, relocating carcasses to off-site centralized facilities can help in limiting the presence of wolves.   The largest variable in these costs is probably size.  Costs go down as the size goes up, which has led some producers to create cooperative efforts.  A simpler version of this system does not include composting, as carcasses are disposed of in alternate places such as landfills. 

Creating successful carcass management projects can be a benefit by having multiple producers from an area work together to share costs of this practice. For example, having a truck and driver that routinely services an area can help reduce costs because of economy of scale. In creating such a communal endeavor, it is important to keep in mind the importance of privacy so that carcasses are not identified to any particular producer.

Livestock Guardian Animal

Livestock guardian dogs can be a useful conflict reduction measure for wolf-livestock predation. The practice utilizes large dog breeds that have historically been bred to protect domesticated animals such as livestock. Unlike pet dogs, livestock guardian dogs (LGDs) are bonded and cohabitate with their livestock, acting as a full-fledged member of the flock or herd. These dogs serve as an extra layer of protection to livestock by conducting perimeter patrols, marking territory, barking/alerting and fighting or chasing predators.   

The use of guard dogs as a practice for reducing predation risk has a long history in the U.S. and other places around the world and is generally a well accepted practice. However, for producers that are unfamiliar with wolves, the use of guard dogs in these situations can create new challenges. The typical breeds (i.e., white dogs) used for protection against predators like coyotes and black bears may not be as suitable for use with wolves or may require a different configuration of individuals to enhance their effectiveness. Wolves bring new challenges because they are large and more effective predators and can create large packs. Questions about the optimal number of dogs and the type of breeds are important to consider. New breeds of guard dogs that are bigger or have more aggressive behavior toward predators may seem appealing but in areas with lots of recreation can create new problems as well. The number of guard dogs also is a cost/benefit exercise because of increased costs associated with more dogs but also because of the social dynamics of having multiple dogs in one area. Finding the optimal balance is an important endeavor and consideration.

Deterrent Devices

Fox Lights – A predator deterrent that is meant to mock the light that would come from someone walking around patrolling with a flashlight. Depending on the brand purchased, the fox lights will flash blue, white and red light periodically in specific sequences. A sensor automatically turns the light on at night and off at dawn and can be seen from approximately 2 kilometers away.  

Solar Sound Alarms – A predator deterrent device that typically has a sensor to detect the motion of unwanted animals that reach a range of 16-26 feet of a specific location. When triggered, the alarm will emit a 130 dB sound alarm and strobe light. These alarms can be either solar or USB charged.  

Game Cameras – Unlike a traditional deterrent device, a game camera will not deter predators in the moment, but reviewed footage can give insight into predator movement and frequency allowing better opportunity to more effectively employ other deterrents and practices.  

Disclaimer and other considerations:

**None of these devices are being promoted as a paid partnership of any kind.

**The annualized cost range of each device is calculated assuming a five-year life span of each of these devices with a 4% interest rate. **There likely exist products that lie in a price range outside of these estimated ranges depending on sales, year sold, changes in manufacturing, etc
