Goat grazing as a wildfire prevention tool: a basic review

Raffella Lovreglio (1)Corresponding author, Ouahiba Meddour-Sahar (2), Vittorio Leone (3)


The general response of most countries to the problem of an increasing number of fires and burned areas has generally been to strengthen fire suppression capacity ([18]). France, Greece, Italy, Spain and Portugal spend a total of 2500 million Euros annually in the fight against forest fires, 60% of which allocated to cover costs related to suppressing fires, while only 40% is invested in activities targeted to prevention ([24]).

Despite the high investment to improve fire suppression resources, mainly through expenditure on important aerial fleets, such as in Spain, Greece or Italy, the phenomenon continues to be characterized by an aggressive trend, with a progressively reduced interval between dramatic years.

Wildfires occurring during prolonged and severe heat waves (such as in 2003 and 2005 for Portugal, 2006 for Spain, 2007 for Algeria, Italy, Spain and Portugal, 2010 for Russia, 2012 for all the Mediterranean countries including Algeria) demonstrate that a different approach must be considered for tackling the problem of forest fires. This means a shift from the short term policy, which is mainly based on huge investments for suppression measures, to a long term preventive policy ([7], [62]).

The key purpose of fire prevention measures is to reduce the number of fires through hazard reduction, education, and law enforcement. Improving prevention strategies seems mandatory if a further reduction in the mean yearly burnt area is to be pursued ([78]).

Fuel treatment and wildfire minimization 

An appropriate approach to wildfire prevention must be aimed at both lessening the possibility of a fire occurring and minimizing its spread should one occur. This can be achieved through fuel treatments for biomass reduction, which are paramount to wildfire abatement ([67]). To reduce fire damages, an infrastructure of roads and water supply should be constructed, firebreaks and fire detection systems established, an immediate and efficient intervention of ground crews ensured, but above all, fuel treatments should be timely executed ([49]).

Fuel treatments are a key factor to decreasing wildfire risk ([68]): they target different fuel components in order to achieve both forest structures and fuel characteristics which are able to reduce the likelihood of fire spread.

Fuel treatments are mainly aimed at eliminating the vertical and horizontal continuity of fuels, in order to disrupt the vertical progression of fire (passage from surface fuels to ladder fuels to canopy fuels), and its horizontal progression, especially from crown to crown ([82], [31]).

Activities aimed at reducing surface fuels (low vegetation, woody fuel, shrub layer) decrease the chances of surface fires igniting ladder fuels and canopy fuels ([76], [25]).

The range of possible treatments to modify forest fuels is rather wide, varying from pruning ([48]) to thinning, to mechanical thinning, to fuel mastication ([36]) to prescribed fire ([50], [25], [61], [77], [3]) to grazing ([39], [79], [78], [57]).

As an alternative to some techniques, a few of which are often perceived as aggressive according to public opinion - such as prescribed fire ([45], [89]) or herbicides - the use of grazing animals could be an efficient method for controlling shrub encroachment and reducing the risk of fire through the elimination of dangerous fuel ladders, as represented by the continuity of grasses and shrubs which enable rapid fire propagation and which permit the transition from high intensity running fires to crown fires ([76], [25]).

All these practices can collectively be targeted as “preventive silviculture”; their main target is crown fire avoidance by treating surface fuels and promoting low density and vertically discontinuous stands ([68]); this also helps to modify fire behavior sufficiently so that some wildfires can be more easily suppressed ([31]). Preventive silviculture manages Mediterranean forests by enhancing their capacity to protect themselves from fires by “creating discontinuities, avoiding very extensive, monospecific surface areas and creating a patchwork of different inflammability levels that disturb the fire” ([90]).

The purpose of this article is to emphasize the importance and the role of grazing, mainly by goats, as a prevention tool against wildfires. Goats can help to mitigate the devastation caused by wildfires by consuming fuels with their specific grazing/browsing habits and thus reducing horizontal and vertical continuity of fuels.

Grazing problems 

In the Mediterranean countries grazing has generally been perceived as negative due to experiences of frequent overgrazing and the use of fire for pasture renewal, both of which can cause the onset of desertification. The combination of wildfires and overgrazing is the main cause of rangeland degradation and desertification in Mediterranean European and in most M.E.N.A. (Middle East and North Africa) countries. On the contrary, if properly managed, grazing can play a positive role in fire prevention while preserving species diversity through the replication of the ecological effects of the wild relatives of livestock ([57]); for this reason it is less likely to elicit a negative public response than the use of prescribed burning, herbicides or thinning.

Grazing is probably the most ecologically sound technique for creating discontinuities in fuels, mainly at the shrubby layer, and disrupting fuel ladders. For this reason it is officially considered as a wildfire prevention tool in many countries such as Italy (article 3 of Law 47/1975, now repealed; many regional laws also include grazing by cattle, sheep and pig as appropriate preventive measures).

As a matter-of-fact, until relatively recent times grazing by domestic animals was considered among the major causes of the destruction of the Mediterranean forests, with goats being singled out for their predilection for woody forage ([22]). Fuel reduction via prescribed herbivory has now become an acceptable and generalized tool, although as little as 15 to 20 years ago the use of livestock was not officially considered an appropriate tool for fuel reduction (e.g., [75] for California).

The goat is the most suitable species for this purpose because of its browsing ability. On the other hand, in the Mediterranean countries the goat has always been considered a detrimental species, negatively called the “razor of the globe” by Cavara ([16]) who coined this image to indicate that goats are destroyers of forests, since they can easily climb young trees and eat all the leaves from branches, or eat all the leaves off seedlings.

A similar image of the “razor of the forests” was adopted by von Mayddel ([91], [92]) who considered goats responsible for damage and degradation of established plants as well as for the destruction of regeneration ([63]).

In the early XIX century some European authors ([6], [33]) provided their own so-called evidence of the negative role of goats, and even accused them of producing environmental catastrophes and evil consequences. This popular assumption has been very hard to dispel ([60], [81], [12]). The controversy surrounding the goat is associated with several interactions with the environment and alleged resource degradation (Fig. 1). Such criticisms are not unique, and can apply to other herbivores, but with goats the allegations are more severe because of their unique mouth parts, selection of feeds, ability to adapt to varying forage quality, their capacity to use coarse grazing and shrubs to their advantage ([20]) and their ability to use forage resources that cannot be utilized by other ungulates such as sheep or cattle ([65]).

Fig. 1 - A herd of goats freely browsing in a public forest in the Tizi-Ouzou wilaya (Algeria). Trees in the background are badly pollarded for fodder. The presence of geophytes (mainly Asphodelus microcarpus Salzm. & Viv.) is an indicator of incipient overgrazing pressure on the ecosystem.

It is often argued that grazing, with goats as the main catastrophic agents, has been a major contributor to deforestation, perhaps even more so than agricultural clearances ([70], [72], [37], [38]).

More likely, because goats are often among the last species able to feed on poor range condition, they are frequently blamed for the damage done by many decades of abuse by other classes of livestock ([32], [71]).

The damaging effect of overgrazing may actually be evident in forests with relatively closed crowns and lack of understorey shrubby vegetation, where goats are forced to browse tree seedlings, young trees or branches of the older trees, thus preventing the regeneration of the forest while at the same time trampling the forest floor and its soil ([70], [51]).

Environmental degradation is also associated with the ownership of goats by landless pastoralists and transhumant who live in poverty and are able to survive only because of the goats. Such situations are not uncommon, especially in the more marginal areas of Asia (e.g., Pakistan, India and China), Africa (e.g., Tanzania and Sudan) and Latin America (e.g., Mexico and Peru - [20]).

Only in recent times has it been realized that goats are not the real culprits but the continuous, uncontrolled overgrazing for which humans are responsible. A threat to forests comes therefore from irrational and uncontrolled goat grazing ([20]): it is the mismanagement of goats, rather than their mere presence, that has resulted in damage to Mediterranean forests in the past ([70], [72], [83]).

Goat feeding habits 

Goats exhibit very peculiar feeding habits: their nimble lips and very prehensile tongue permits them to graze on very short grass and to browse on foliage not normally eaten by other domestic livestock, which all combines in an excellent nutrient conversion efficiency for the production of milk (about 45% - [39], [28]).

Goats are facultative browsers; they prefer to feed at eye level and upward and then feed on forage from the top of the plant down ([34], [41]). They move freely from plant to plant, removing foliage from select portions of plants. Foliage meals are dictated by quality factors that ensure adequate protein and energy levels. Unlike larger ruminants, there is little fouling or treading of forage ([41]).

Goats are often considered to prefer feeding more on shrubs than on grass; they really take a wider variety of plants than other classes of livestock but selectively feed if there is a choice ([32], [94]).

Goats feed on a variety of shrubs, some of which are useless for other domestic species, exhibiting a relevant capacity for transforming otherwise useless crude fiber into noble proteins; they are therefore the best adapted species for the consumption of all Mediterranean shrubs ([32]), providing for an exception of those with high aromatic oil content which are less palatable (Rosmarinus officinalis, Lavandula stoechas, etc. - [57]). Because of their unusual preferences for the leaves and terminal twigs of woody plants, goats have been exploited as an alternative to herbicides and mechanical cutting against encroaching herbaceous weed and brush species, provided the targeted plants are palatable.

Thanks to their inquisitive nature and tolerance of high tannin material, goats may eat unpalatable weeds and wild shrubs that may be poisonous, but they are often not affected by poisonous compounds or anti-nutritional factors if a sufficient number of other plant species are available. Because goats prefer to consume a very varied diet, the detrimental effects of poisonous compounds found in certain plants can be diluted ([54]).

The propensity of goats to stretch upwards on their hind legs allows them to commonly browse up to a height of 2 meters in areas where trees and hanging vines are present ([53]). Reports that browsing goats are able to reduce tree growth and slow down woodland expansion in aspen stands, until individuals reach an escape size of 1.5 m in height ([4]), is confirmed by the findings of other authors ([23] for eastern Cap Region in South Africa, [26] for Mexico).

The types of vegetation present influence the foraging position or posture of goats, most notably the use of a bipedal stance and aerial positions. Goats will only use a bipedal stance if trees are present and will only adopt aerial foraging positions if the trees present are climbable ([29]).

Here stays the goat’s main role in wildfire prevention, as they easily consume grasses or forbs before they are classified as the 1h and 10h time-lag (a fuel’s time-lag is proportional to its diameter and is loosely defined as the time it takes a fuel particle to reach 2/3’s of its way to equilibrium with its local environment) dead fuel categories described in the literature ([19]). In other words, goats reduce the availability of dead fuels with a diameter of <2.54 cm and the availability of small live fuels (terminal twigs of woody plants such as shrubs and trees), both of which are the main propagators of fires as components of the lower layer of the fuel ladder. The grazing of goats can impact the amount and arrangement of these fuels by ingestion or trampling ([64]).

Grazing at moderate levels has been shown to change wildfire behavior, by slowing its spread, shortening flame length, and reducing fire intensity, although it does not significantly reduce the risk of fire ignition ([84]). In the vicinity of urbanized areas, grazing can prevent or minimize expansion of shrublands which have much greater fuel loading and pose greater fire hazard than grasslands ([84]).

Grazing can directly reduce the frequency and intensity of fire by removing fine fuels and amplifying the heterogeneity of fuel continuity, and indirectly by causing a shift in plant community composition to less-productive and more-ephemeral species ([27]).

In Mediterranean areas, where shrubland often prevails, co-grazing with sheep, cattle and horses, which have mainly grazing habits, could greatly improve grazing of grass thus further reducing fuel load. Since goats, cattle, and sheep prefer different forages, in many pasture situations these species do not compete for the same food ([14]).

In some cases, the integration of different treatments represents the best strategy. Livestock cannot effectively control mature brush plants that either grow higher than the animals can effectively graze or which have large diameter limbs. As a solution, underburning and/or cutting can be used to eliminate the large-diameter, 100-hour brush fuels, and grazing can be used as a follow up treatment for controlling resprouting species or shifting the species composition to herbaceous plant fuel material ([64]).

The goat has a strong ability to adapt its feeding behavior to the chemical characteristics of food: several studies report selection by goats between diverse plant species, or between individuals of the same plant species according to nutritional quality or the concentration of chemical defenses ([5]).

Under natural conditions, goats range over a large area, grazing and browsing selectively. Under confined conditions, however, goats will become heavy browsers of trees and shrubs, and less discriminating in their grazing habits, due to the reduced supply of available herbage ([35]).

Goats are not pure browsers: the yearly diet of goats is very variable, as an average about 60 percent shrubs, 30 percent grass and 10 percent forbs ([70]) and almost always contains high proportions of lignified components whenever woody species are presents within the pasture, with a wide range of percentage (62-94% - [65]).

Lopez-Trujillo & Garcia-Elizondo ([52]) observed that grasses are selected in a low proportion by goats, even in shrubland reseeded with grass. Papachristou ([73]) reported a greater rate of biting by goats when available forage was primarily browse vs. non-browse plant species; Nastis & Nolan ([66]) reported that goat diet under different brush cover was mainly based on browsing (53-65.6%) followed by grass (13.1-22%) and forbs (16.5-20.3%).

Goat and fuel break management: first experiments 

If confined behind a strong fence, goats browse all the available foliage including all woody plants as well as all herbaceous vegetation ([32]); this is the basis for the use of goats as a brush clearing tool for the construction of firebreaks ([8], [9], [15], [86]).

In Europe the first experiment of controlled grazing for a brush clearing action dates to the ’80s in France, where the Forestry Services of Gard wanted to clear a space to serve as a fire-break. A local goat-breeder proposed to clear the area using his goat herd at a considerably lower price than a traditional land-clearing team.

The area was divided into pens of 0.5-1 ha, each enclosed by metal fences. The pens were opened one after another, with a stocking density (number of animals per unit area of land at any one point in time; can be expressed as animal units/ha) of 100-200 animals per ha. The goats were allowed into the pens for only 4-6 hours a day. In six months a firebreak of 100 x 1000 meters was created. The goats ate 2300 kg of edible dry matter per ha out of the available 2900 kg, getting 60-75% of their food requirements by grazing and an increase of up to 10 percent of their live weight per month ([70]).

Further experiments were carried out in Languedoc Roussillon region (1985-2005) on a total area of 27 049 ha but the area reduced to a few tens of hectares in 2005 due to budgetary problems ([22]).

In Spain, farmers that take part in wildfire prevention programs make their livestock graze intensively in the fuel break areas defined by Forest Services. In exchange, they receive money and/or in-kind remuneration. In Comunitat Valenciana (eastern Spain), a payment of € 22 ha-1 yr-1 is given to farmers who concentrate their livestock in fuel breaks for a minimum of 130 days. A minimum stocking rate (number of animals per unit area of land over a specified period of time; can be expressed as AUMs/ha - differs from Stocking density by incorporation of time) of one cow, three goats or five sheep per hectare must be maintained; the payment can be increased by some € 20-40 ha-1 yr-1 if water or a fence are necessary ([80]).

Similar programs are currently under way in Aragon (3500 hectares of firebreaks) and Andalucía, where the payments per hectare currently range from € 42 to 90, depending on the grazing difficulty (steepness, type of vegetation and distance to animal housing - [79]).

The reduction of shrubs by grazing goats intensively within the firebreaks is less costly than other alternative treatments; in addition, the presence of goatherd and dogs constitutes a deterrent to arsonists and ensures early detection ([79]). We have no knowledge of similar projects in other countries of the EU, where goat grazing for wildfire prevention purposes is still in an experimental phase ([95]).

On the contrary, in the USA, where goats have been used for vegetation management for over a hundred years ([39]), their use in wildfire prevention has been considered a relative success, since they are environmentally friendly and the most cost-effective, nontoxic, nonpolluting solution available.

The use of goats herds is documented in US military camps, such as Camp William (Utah National Guard training field), where no prescribed burning nor herbicides can be employed ([11], [59]), and in the town of Oakland where a budget of 1 750 000 US$ is allocated to wildfire prevention using goats ([93]).

Los Angeles, Laguna Beach and the Scripps Ranch community of San Diego have also brought the animals in to clear overgrown areas and assist with wildfire prevention ([10]).

Intensive grazing at the urban interface can create effective firebreaks, as was accomplished near Carson City, Nevada. A fenced corridor around the city was grazed resulting in the removal of 71 to 83% of fine fuels ([85]).

In hills around Menlo Park, Oakland, Los Altos, and Berkeley, California, goats have reduced fuel loads in areas too steep for manual labor or mowers. They remove vegetation without disturbing roots or facilitating erosion ([85]).

More recently, the use of goat grazing is reported throughout other areas of the USA (e.g., Atlanta, Chicago and San Francisco airports; Auburn, CA; Boise, ID; Laguna Beach, CA; Santa Barbara, CA). Goat-powered fuel reduction costs between US$ 400-500 per acre (4046.85 m2 equivalent to about 40% of one hectare), nearly one-third of the cost of more labor-intensive methods of brush clearing ([88]). Domestic livestock grazing (without further details about species) is also a prevention measure officially mentioned within the Catastrophic Wildfire Prevention Act, S.14799, 113th Congress, re-introduced 08.01.2013 by the USA Congress ([30]).

Probably the most popular example of wildfire prevention by goats is by Google, in their headquarters of Mountain View campus, in west California; the success of such a low-tech “green mowing” initiative resonates well with the well-publicized global ideal of carbon footprint reduction, underlining that goats are an effective method of nearly carbon-neutral weed control. Since 2009, the presence of 200 goats with their kids and a goat herder, helped by a nice Border collie, delight Google people and public opinion, for goats in many people’s eyes are more pleasing to watch than lawn mowers ([1], [10], [43]).

Goats have also got the green lights from PETA (People for the Ethical Treatment of Animals) which has hired goat to mow its lawn ([43]).

In Europe, an interesting study case is Matadepera, in the Barcelona Metropolitan Region, where a flock of 200 goats and sheep is being used as a prevention tool by the municipality to control sprouting and to maintain a low fuel load within the coppiced stands ([69]) at a yearly cost of € 20.000.

Use of goats for wildfire prevention 

For wildfire prevention purposes goats cannot merely be put out to eat a plant: the proper choice of season of grazing, livestock density, social structure of herd, grazing time per day, type of fencing, size of pens define an appropriate prescribed grazing system, in strict analogy with prescribed burning ([85]).

Prescribed grazing, prescribed herbivory ([75]) or targeted grazing can be defined as the application of a specific kind of livestock at a determined season, duration, and intensity to accomplish defined vegetation or landscape goals ([47]).

Grazing is a complex tool with many plant and animal variables, including: (I) the species of livestock grazed (cattle, sheep, goats, sometimes horses or a combination); (ii) the animals’ previous grazing experience (which can affect their preferences for certain plants); (iii) time of year as it relates to plant physiology (animal consumption is directed by the seasonal nutrient content); (iv) animal concentration or stocking density during grazing; (v) grazing duration; (vi) plant secondary compounds; and (vii) animal physiological state ([64]).

The use of grazing as a wildfire prevention tool can either be treated as a short-term measure to reduce flammable vegetation (type of plant species and type and amount of biomass to be eliminated: leaves? twigs? stems?) or a long term measure to change vegetation composition by depleting root carbohydrates in perennials and reducing the soil seed bank for annual plants.

The main objectives of wildfire prevention through grazing are to change fire behavior through the modification of the fuel bed, fuel loading, percent cover, and ladder fuels.

As an example, Chapman & Reid ([13]) report that in a mixed shrubland in Nevada, using a stocking density of 1.1 Animal Unit Month (AUM) per acre for 30 days in May, 73% of the forage was eaten, ground litter was reduced by about 60%, and vegetation height was reduced by approximately 75%. Fire experts estimated this would decrease the rate of spread of a fire by about 75% and reduce the likely height of the flames from 6’-10’ (182-305 cm) down to about 2’-3’ (61-92 cm).

In any case, grazing for wildfire prevention requires skilled herders. Also, the problem of the social stigma attached to goats and goat herders still remains ([32]). Perhaps that stigma comes from the distinctive odor of active breeding male goats ([2]).

Goats must be confined in pens of an area of approximately 0.9 hectares which are enclosed by a traditional metal fence, electrified netting or por-wire polywire fence. An electrified fence must be energized by low impedance battery-powered fence energizers, which send a pulse of electricity through the wires, eliminating the possibility of overheating. Solar panels can be used to keep batteries charged. Predators, if any, can be discouraged by electric fencing ([17]).

Goats require better fences than sheep or cattle to ensure their containment, namely sheep and goat net wire which has a wider space between the vertical stays.

In order to maximize fuel reduction, a high stock density is necessary when a complete elimination of biomass is required ([17]).

Existing data indicates there are two ways in which grazing impacts the fuel load; removal of vegetation and hoof incorporation of fine fuels. Tsiouvaras et al. ([87]) report that in a California Monterey pine and eucalyptus forest in the fall at a stocking rate of 113 Spanish goats per acre for 3 days, the brush understory was reduced by 46% and 82% at 20 inches and 59 inches in height respectively.

Goat grazing not only broke up the sequence of live fuels (horizontally and vertically up to 59 inches), but also reduced the amount of 1-hour dead fuels by 58.3%, although the 100-hour fuels remained constant.

The litter depth was also reduced as much as 27.4% (from 2.9 inches before to 2 inches after grazing). Animal trampling which crushed fine fuels and mixed them into the mineral soil thus reduced the chance of ignition.

Lindler et al. (1997 in [42]) reported that goats stocked at 7 per acre for 3 weeks in the summer in a ponderosa pine forest were estimated to remove 15-25% of the vegetation, depending on the plant species present and the length of stay in the pasture. The same authors reported that a stocking rate of 37 goats per hectare in a California pine forest is required to effectively treat understory brush.

The high stock density in such a small space creates many trails, which act as mini-fuel breaks that help break up the continuity of available fuel ([59], [44], [56]).

Dogs are a main part of the system, even though their barking may not be welcome in some areas such as in the wild land-urban interface. They help to contain livestock and move animals into and out of paddocks and into the trailers for their transport ([1]).

Pros and cons: a reduced SWOT 

We can summarize current knowledge about goats as wildfire prevention tools as reported in Tab. 1 ([74], [55], [46], [58], [57]).

Tab. 1 - Strength-weakness points of goats use in fire prevention.

Summary and conclusion 

Prescribed goat grazing has the potential to be an ecologically and economically sustainable management tool for the local reduction of fuel loads, mainly 1h and 10h fine dead fuels and smaller diameter live fuels. These fine dead fuels can greatly impact the rate of spread of a fire and flame height, both of which are responsible for fire propagation ([74], [64], [57]).

Far from being a simple technique, prescribed goat grazing is more complex than simply putting a goat out to eat a plant; it requires careful evaluation of the type of animals and planning of timing. The technique also requires further research, since information about grazing for fuel reduction is anecdotal and there is only limited scientific information currently available, mainly for the Mediterranean area ([64], [44]).

The economically sustainable use of prescribed herbivory could be used for ([85], [21], [40]):

  • maintenance grazing of fuel breaks with mixed goat-sheep flocks;
  • high impact browsing where prescribed burns are not possible (high cost service);
  • specialized impact browsing in timber plantations (medium/high cost service);
  • follow-up on burned areas (short term).

Goats are the most cost-effective, non-toxic, non-polluting solution available; they are greatly appreciated by the general public and they are an environmentally friendly and effective method of nearly carbon-neutral weed control which deserve further attention and applied research.
