Woody Encroachment
Ranchers in the Loess Canyon are proving its possible to restore healthy grasslands by fighting trees with fire!
Over this Summer a 15 year study on prescribed fire was published which demonstrated:
-A reduction in tree cover from 50% to 10%
-An increase in plant diversity/abundance
-Grasses that sustained themselves for up to 15 years after the initial burn
In addition these prescribed fires were found to:
-Increase the number of American burying beetles
-Increase bird species richness by up to 65%
Because prescribed fires are such an advantageous tool the Prairie Project uses them in junction with livestock to help remove woody invasive plant species.

Why is grazing management important?
The #1 Land use in Oklahoma is grazing of Rangelands, Pasture and Forests
58% or 25 million acres
45% Grazed Rangeland & Planted Pasture
13% Grazed Forest
4% Ungrazed Forest
16% Cropland
12% Urban, special use, Miscellaneous
Stocking rate is the most important grazing management decision for sustainability of...
Across Oklahoma, stocking rates range from 10-60+ acres per cow for 1 year (1,300lb cow) on native pastures.

Multi-Species Grazing
Does your livestock match your pasture?
Cattle, sheep and goats use pastures differently.
Grazing multiple species can often be complementary, resulting in broader use of available plant types and pasture terrain.

Prescribed Fire & Patch Burn Grazing
Patch burn research has shown that cattle use annually burned pastures differently than patch burned pastures.
A 2010-2012 study found that cattle occupied burned patches approximately 70% of the time, while cattle in annually burned areas occupied the pasture more uniformly. Livestock prefer grazing areas that have been recently burned because the plant regrowth provides nutritious and palatable forage.

Prescribed Fire & Patch Burn Grazing
Stockpiling for Drought Under Continuous Grazing?
Patch Burn Grazing
- One part (patch) of a pasture is burned.
- Cattle graze primarily on the most recent burn.
- When a new area is burned, cattle rotate themselves to the newest patch.
(Six weeks since fire. Burned Aug 5, 2022)
Forage Stockpiling
- Cattle avoid older burns.
- Forage is stockpiled for multiple years.
- 4,400 - 5,200 lbs/acre stockpiled after 2022 drought.
(2.5 years since fire. Burned Feb 2022)
During drought..
forage is available for grazing
fuel is available for burning

Prescribed Fire & Patch Burn Grazing
What is Patch Burn Grazing?
- A part of the pasture is burned (patch burn)
- Livestock are attracted to regrowth in the burned patch (pyric herbivory)
- Other patches receive rest and accumulate fuel
- The next patch is burned, moving animal use to this area
Why use it?
- Provide higher quality forage for livestock in recent burn
- Promote plant diversity and variable structure for wildlife
- Control woody plants without grazing deferment
Other considerations
- Livestock must have immediate access to the burn patch
- Stocking rate should be calculated as normal for the full pasture

Patch Burn Grazing Benefits Northern Bobwhite Broods!
SITE SELECTION
Broods selected areas with... greater proportions of native grass managed with burning & grazing
SURVIVAL
Brood survival was greater where native grass as burned & grazed within the last two growing seasons.
Broods that survived to 35 days showed stronger selection for shrub cover than broods that failed.
Batch Burned & Grazed Native Grassland
Patch burning increases broadleaf plants providing cover, seeds, and insects (food).
cover: from predators & weather
seeds: foood for adults
insects: food for chicks
Northern Bobwhite broods had greater selection for AND survival on patch burned & grazed sites.

Are horn flies causing problems for your cattle? Research indicates that patch burn grazing could help!
Horn flies are a costly parasite to livestock production. They can increase stress, cause weight loss, and result in blood loss to the animal. While insecticides are the primary method for control, over time horn flies can develop resistance to the effective agents.
In a 2012 study by Scasta et al., management systems featuring patch burn grazing resulted in 41% less horn flies on cattle compared to traditional systems in both Iowa and Oklahoma sites. These findings indicate that the interaction between fire and grazing animals could be a possible tool to address horn flies as chemical control measures become less effective.

Prescribed Fire & Patch Burn Grazing
Yearling stocker cattle performance was equal in annually burned and patch burned pastures during normal and wet years. In dry years (2011, 2012) stockers grazing patch burn pastures gained more than those grazing on annually burned pastures.
�cattle on PB had a greater ADG (P = 0.02; 0.10 kg/d), final weight (P = 0.07; 12 kg), and total BW gain (P = 0.02; 11.8 kg) in low precipitation years (2011 and 2012). Overall, patch burning provides similar BW gains as yearly burning on native tall-grass prairie, while providing a BW gain advantage in low precipitation years.�

Prescribed Fire & Patch Burn Grazing
An 11-year study compared stocker performance in patch burned pastures versus traditionally managed pastures in western Oklahoma at OSU�s Marvin Klemme Range Research Station. Researchers found that from 1999-2001 there was no statistical difference in stocker weight gains in the traditionally managed versus patch burned pastures.
In 2002, the stockers in the patch burn pastures started gaining more weight and continued to gain more weight through the end of the study in 2009 (Limb et al. 2011). By 2002 the full rotation of burning had been completed in all patches and the full benefits from patch burning were captured by the grazing steers.

Prescribed Fire & Patch Burn Grazing
In abnormally dry years you can keep cattle weights stable by working with the landscape!
Rainfall and stocking rate are two of the most important factors in livestock production. Although annual precipitation cannot be controlled, negative effects of a dry year can be lessened through patch burning. Burned patches increase forage quality, while unburned areas provide more pounds of available forage. Producers can benefit from forage variation by influencing this fire-grazing interaction.
