Eastern Redcedar: Why Oklahoma Is Acting
Eastern redcedar control is becoming one of Oklahoma’s biggest land, water, and wildfire issues—and this episode explains how the Oklahoma Conservation Commission is turning concern into action. John Weir, Laura Goodman Ph.D., and Mark Turner Ph.D. visit with Trey Lam and Trampas Tripp about the Terry Peach North Canadian Watershed Restoration Pilot Project, a program designed to reduce invasive woody species, protect rural communities, improve rangeland health, and put more water back into Oklahoma soils and streams.
The conversation covers how cedar control moved from years of talk to funded work on the ground, including brush-free zones around towns and infrastructure, prescribed fire training with rural fire departments, cost-share programs for landowners, and research measuring soil moisture, forage recovery, wildlife response, and wildfire risk. The episode makes one thing clear: managing cedars is not just about removing trees—it is about protecting rural lives, homes, grasslands, water supplies, wildlife habitat, and the future of working lands.
Top 10 takeaways
1. Cedar control is public safety work. Removing dense cedars near towns, homes, propane tanks, fertilizer plants, towers, and roads can give firefighters safer access and slow wildfire spread.
2. The Terry Peach Project turned years of talk into action. Oklahoma had studied eastern redcedar for decades, but the combination of drought, wildfire, water concerns, and available funding finally produced a funded program.
3. Brush-free zones are a practical first step. The program is not always trying to clear entire properties; it often starts by creating strategic fire breaks and access corridors.
4. Rural fire departments are key partners. The program is helping firefighters understand when prescribed fire can reduce future wildfire risk instead of treating all fire the same.
5. Prescribed fire and “controlled burns” are not the same thing. A prescribed fire has a plan, weather parameters, trained people, equipment, and a go/no-go decision process.
6. Cedars cost landowners forage. Dense cedar stands can shade out grass, reduce grazing capacity, and lower the productive value of rangeland.
7. Cedars are a water issue. Guests discussed early findings showing major soil moisture differences between dense cedar areas, treated areas, and open native range.
8. Wildlife responds when cedars are removed. The episode highlights benefits for quail, deer, and especially wild turkeys when cedar-choked areas are reopened and roost trees are protected.
9. Landowner demand is high. The new cedar-removal cost-share pilot received more than 500 applications, showing that many Oklahomans are ready to act.
10. The next challenge is scaling statewide. Oklahoma’s cedar problem varies by region, and future work may need to address salt cedar, mesquite, mountain juniper, and other invasive woody species with different control strategies.
Detailed timestamped rundown
00:00:00 — Sponsor and episode setup
The episode opens with the Oklahoma Conservation Commission sponsor message and frames the conversation around cedar control, safer towns, healthier rangeland, and water conservation.
00:02:16 — Guest introductions
John Weir welcomes Trey Lam and Trampas Tripp from the Oklahoma Conservation Commission. The hosts set up the episode as a discussion of one of the state’s most visible conservation programs.
00:03:20 — Trampas Tripp’s background
Trampas explains his path from college and early work with the Corps of Engineers into the Oklahoma Conservation Commission, where he now leads the Land Management Division.
00:04:16 — Trey Lam’s conservation roots
Trey shares his background growing up on a southern Oklahoma farm and becoming involved in conservation districts before becoming executive director of the Oklahoma Conservation Commission.
00:05:02 — How the Terry Peach Project began
Trey explains that Oklahoma had talked about eastern redcedar for years, but drought, wildfire, water disputes, and state funding finally aligned to create action.
00:07:46 — The original three-part approach
The project began with research, prescribed fire training, and brush-free zones. The goal was to measure water, soil moisture, grass production, wildlife response, and wildfire mitigation benefits.
00:12:15 — Rural fire departments join the effort
Trampas describes how the program works with fire departments to shift from only reacting to wildfire toward using prescribed fire and fuel reduction as prevention tools.
00:13:22 — Fighting Fire with Fire workshops
John and Trampas discuss the workshops that combine classroom training with hands-on burning when conditions allow. Around seven workshops had been held, with strong interest from across the state.
00:14:00 — Ada workshop draws major attendance
The Ada training brought about 100 attendees and 25 fire departments, including some from Kansas, showing regional interest in Oklahoma’s prescribed fire model.
00:15:32 — Brush-free zones and mitigation crews
Trampas explains that 14 technicians are working across the state to remove volatile woody fuels near communities, infrastructure, and high-risk areas.
00:16:07 — Protecting infrastructure in Woodward
Trey gives the example of work near a fertilizer plant on the southwest side of Woodward, where cedar removal created safer access and reduced wildfire risk.
00:17:34 — Towers, propane tanks, and rural hazards
Laura and Trampas discuss examples near communication towers and propane infrastructure where cedar removal created safer zones around critical facilities.
00:19:51 — Burn plans and prescribed fire cost-share
The group discusses growing demand for prescribed burn plans and a $20-per-acre prescribed fire cost-share program for landowners.
00:21:13 — Prescribed fire versus wildfire
The hosts emphasize that prescribed fire is planned, weather-dependent, staffed, and equipped—very different from wildfire or informal “controlled burns.”
00:22:55 — “Controlled burn” confusion
Trey and John explain how media and public language often blur prescribed fire with escaped brush-pile or trash burns, which creates misunderstanding.
00:25:29 — Why cedars are such a large problem
Trey lays out the impacts of cedars on wildfire behavior, water use, grass production, quail, deer, and other wildlife habitat.
00:26:08 — Wildlife impacts and turkey roosts
Mark explains how cedars can eliminate cottonwoods and other roost trees, creating long-term habitat losses for wild turkeys.
00:27:11 — Soil moisture findings
Trey discusses early findings showing dense cedar areas with very low soil moisture compared with native range and treated areas.
00:30:03 — Rainfall interception and runoff
John and Laura discuss research showing how dense cedar canopy can prevent rainfall from reaching the ground and how restored grasslands can improve cleaner runoff.
00:33:21 — Health, ticks, mosquitoes, and public awareness
The conversation expands to the human-health and public-comfort impacts of cedar-dominated areas, including pollen, ticks, mosquitoes, and smoke particulates.
00:34:52 — Legislative support and changing attitudes
Trey explains how cedar control has moved into mainstream policy discussions, with lawmakers increasingly recognizing the scale of the issue.
00:40:27 — New cost-share demand
Trampas says a pilot cost-share program received more than 500 applications, showing strong landowner interest in cedar removal.
00:42:17 — How landowners access the program
The first step is contacting the local conservation district. Applications are ranked by acreage, density, removal method, management approach, and other factors.
00:43:41 — Targeted priority areas
Trey explains why the program focuses on specific high-impact areas, including Beckham County to Altus Lugert, the Panhandle, Payne-Lincoln-Pawnee, Eufaula, and the Blue River.
00:45:14 — Community mitigation work
Trampas describes technicians working with emergency managers and communities to build defensible spaces and demonstration areas.
00:47:27 — Cedar rows as wildfire fuses
Trey describes abandoned railroad corridors and other unmanaged strips as “fuses” that can carry fire directly into rural towns.
00:48:20 — Future expansion
Trey discusses hopes to expand the program statewide and adapt it to other invasive woody species, including salt cedar, mesquite, mountain juniper, and eastern Oklahoma invasives.
00:49:36 — Wrap-up
The episode closes with thanks to Trey, Trampas, and the Oklahoma Conservation Commission for supporting the podcast and advancing cedar-control work across Oklahoma.
