If you own land in Oklahoma, there is a good chance cedar trees are slowly taking over your property. Eastern red cedar is the most aggressive invasive tree species in the state, and it is spreading at a rate that most landowners do not fully appreciate until the problem has already cost them significant money in lost grazing capacity, reduced property value, and increased wildfire risk.
The Scope of the Problem
Oklahoma has lost millions of acres of productive grassland to cedar encroachment over the past several decades. Eastern red cedar is not native to the Oklahoma prairie — it is a bottomland species that historically stayed in creek bottoms and rocky outcrops. The suppression of natural prairie fires (which historically kept cedar in check) combined with decades of seed dispersal by birds has allowed cedar to colonize pastures, rangeland, and hay meadows at an alarming rate.
A single mature female eastern red cedar can produce thousands of seeds per year, and those seeds are spread by birds who eat the berries. A pasture that has a few scattered cedars today can be overtaken within 10 to 15 years if nothing is done. The canopy eventually shades out native grasses completely, turning productive pasture into cedar thicket with zero grazing value.
What Cedar Encroachment Costs You
Lost grazing capacity — Every acre lost to cedar is an acre your cattle cannot graze. For ranchers running cow-calf operations, this directly reduces carrying capacity and revenue. Research from Oklahoma State University has estimated that cedar encroachment costs Oklahoma ranchers hundreds of millions of dollars annually in lost forage production.
Reduced water availability — Cedar trees are notorious water consumers. A mature eastern red cedar can use 30 to 40 gallons of water per day. On properties with ponds, springs, or seasonal creeks, dense cedar stands can measurably reduce water flow and lower pond levels.
Wildfire fuel — Cedar is extremely flammable. Its dense, resinous foliage burns hot and fast, and cedar thickets are the primary fuel source for many of Oklahoma’s most destructive wildfires. Dense cedar stands near structures, fences, and livestock create serious fire risk.
Decreased property value — Land buyers, especially those looking for ranch, hunting, or recreational property, discount the value of cedar-choked land because they know the cost of clearing it. A property with clean, open pasture and healthy native grass commands a significantly higher price per acre than one overtaken by cedar.
Lost wildlife habitat quality — Dense cedar monocultures support far less wildlife diversity than native grassland. Quail, turkey, and songbird populations decline as cedar replaces the grass and forb habitat they depend on. Deer use cedar for cover, but even deer benefit from a mix of open grassland and timber rather than solid cedar thicket.
How Forestry Mulching Solves the Cedar Problem
Forestry mulching is the most efficient way to reclaim cedar-invaded land. A skid steer-mounted forestry mulcher processes cedar trees of all sizes — from 2-inch saplings to 12-inch trunks — grinding them into mulch on-site. The mulch stays on the ground as a temporary erosion barrier and decomposes over one to two growing seasons, allowing native grasses to reestablish naturally.
Unlike bulldozing, which rips up topsoil and root systems, forestry mulching preserves the soil structure and seed bank. Native grass recovery is significantly faster after mulching compared to dozer clearing because the soil biology remains intact and grass seeds already present in the soil can germinate in the first growing season.
Oklahoma Programs That Help Pay for Cedar Removal
The good news is that Oklahoma has recognized cedar encroachment as a critical land management issue, and there are programs available to help offset the cost of removal. The Oklahoma Forestry Services offers grants for invasive cedar removal, and USDA programs through NRCS (Natural Resources Conservation Service) may provide cost-share assistance for brush management on qualifying agricultural land. Contact your local NRCS office or the Oklahoma Forestry Services to learn about current eligibility and funding.
Take Action Before It Gets Worse
The most important thing to understand about cedar encroachment is that it only gets worse and more expensive to fix the longer you wait. A pasture with scattered young cedars can be cleared quickly and affordably. The same pasture five years later, with dense cedar stands and dead grass underneath, is a much bigger and more expensive project.
