Prescribed Fire & Patch Burn Grazing
"The grass is at times green and short and at other times tall and white… nothing but bare prairie, which becomes confused in the distance with the smoke of burning grass."
- Washington Irving, 1832, From A Tour on the Prairies
Historically, frequent wildfire burned parts of the prairie, attracting bison, elk, deer & pronghorn to the nutritious regrowth.
Today, patch burn grazing with cattle & goats mimics this providing quality forage & wildlife habitat diversity.

Prescribed Fire & Patch Burn Grazing
Patch Burn Grazing Pasture
What is patch burn grazing?
Burning: each year _ of the pasture is burned in the spring.
Grazing: cattle can graze any of the three patches and have access immediately after fire.
Effects: cattle focus grazing on the recently burned patch. This provides rest to other patches without requiring additional fence.

Prescribed Fire & Patch Burn Grazing
In 1965, 4.6 million goats existed in the Texas Hill Country, and juniper encroachment and wildfires were managed. Over the last fifty years that number has dropped to less than 1 million, and the total amount of wildfires and juniper have increased at an alarming rate. However, a new solution has presented itself in the form of pyric herbivory or �herbivory promoted through the use of fire�. The Prairie Project has established demonstration ranches throughout Texas, Oklahoma, Nebraska, and Kansas to ensure this knowledge is passed along to producers, resource managers, agribusiness leaders, and the public who are also fighting the battle against woody plant encroachment.

Rate of Wildfire Spread is Slower with Prescribed Burning + Grazing.
Wildfire Conditions: 25mph wind, 5% fuel moisture
Prescribed Burn Only VS Prescribed Burn + Grazed.

Wildlife Management
Do Wild Grazers Prefer Recent Burns?
Pyric Herbivory: Instinctual foraging driven by high-quality regrowth after recent fire.
- Shifts use by wildlife and livestock.
- Provides rest to unburned areas and waterways.
- Creates habitat variability for other wildlife.
White-tailed Deer
In burned areas, roundhead lespedeza was grazed and purple prairie clover was preferred while both were avoided in unburned areas. Percent of plants grazed was higher in burned areas than unburned (Nisi et al. 2015).
Elk
Up to 1 year after fire, elk use days on burned areas increased by an average of 94 while elk use days on unburned areas decreased by an average of 69 (van Dyke & Darragh 2007).
Mule Deer
Selected for prescribed burns in almost all seasons with greater selection for more recent burns (<2 years old) (Roerick et al. 2019).
Pronghorn
Used burned range significantly more than unburned. They used burned prickly pear cactus heavily (Courtney 1989).
Bighorn Sheep
Used burned sites more than adjacent unburned sites on all areas studied (Brentz & Woodward 1988).

Wildlife Management
Windbreaks & Shelterbelts:
Ecological Traps for White-tailed Deer Fawns
Higher Fawn Survival: Where more grassland patches in home range.
Lower Fawn Survival: Where more shelterbelts in home range.
Tree plantings attract female deer seeking fawn cover. Unfortunately, coyotes can easily search these plantings, locating fawns and increasing predation mortalities.

Woody Encroachment
The final species in this three part Cedar Series is Ashe Juniper. Also known as blueberry cedar, this tree produces berries that are blue and fleshy. Like Eastern Redcedar, Ashe juniper is non-resprouting and can be controlled with fire in a similar manner. Ashe juniper is a smaller tree than Eastern Redcedar and will only reach mature heights of 15-30 feet. This species often has a single trunk and a shredding bark texture. Although this tree is commonly confused with Redberry Juniper, no wax flecks are present on the leaves of Ashe juniper.

Know your cedar!
Eastern Redcedar is the second species in this series. It is the most abundant in the Southern Great Plains. This cedar type is non-resprouting and is readily controlled with fire. Historically, this plant was only found in rocky areas and other places where wildfires rarely reached. Eastern Redcedar can reach heights over 60 ft. tall and has rapidly spread through prairies following the suppression of fire. Smaller trees are easily managed under “normal” burning conditions, but larger tree control may require more extreme burning conditions or mechanical control. This plant can be identified by its evergreen scaly leaves, pyramid-shape and blue cones or ”berries”. In some locations, it is reported to hybridize with Ashe Juniper.

Woody Encroachment
Know your cedar!
Different types of native juniper, or cedar, are found throughout the Great Plains. Fire can be an effective tool to manage juniper encroachment; however, some cedar species are able to resprout after fire, making them difficult to manage with fire alone. This series will focus on identifying three key species of juniper in the southern Great Plains and classifying them as resprouting or non-resprouting.
The first species in our cedar series is Redberry Juniper. Redberry is a multi-stemmed, shrubby tree that is commonly found in the northern and western parts of Texas and southwest Oklahoma. The smallest of the three in this series, Redberry only matures to heights up to 15 feet. This species does resprout after fire, so it is usually considered a nuisance and may be difficult to remove after it has established itself in a landscape. Although closely resembling Ashe juniper, Redberry can be distinguished by the wax-like, white residue found on the leaves by resin producing glands.
Helpful tip: Goats will browse the palatable regrowth of redberry juniper after fire. This is a great way to incorporate multi-species grazing & pyric herbivory into your rangeland management practices!
