The Challenge of River Bottom Terrain
Clearing land near rivers in Idaho presents a unique blend of beauty and difficulty. The soil is often a mix of gravel, silt, and embedded rocks, shaped by centuries of glacial runoff and seasonal flooding. In the case of a ranch near Mackay, Idaho, the goal was to transform a rocky cottonwood-covered riverbank into a seeded meadow of native grasses. The land had recently gained access via a restored 1902 iron truss bridge, adding historical charm to the project.
The terrain included dense cottonwoods, uneven ground, and a high concentration of stones ranging from fist-sized to small boulders. While the soil contained pockets of loam, the dominant substrate was rocky, raising concerns about seed germination and water retention.
Terminology Notes
The ranch was equipped with a 1979 CAT D3 dozer, a CAT 308 excavator, a CAT 299D2 HXP skid steer (awaiting attachments), a CAT 420E backhoe-loader, and a John Deere 4720 compact tractor. This fleet offered flexibility for tree removal, grading, and soil preparation.
Recommended sequence:
One operator in Michigan noted that prairie grasses, with root systems reaching over 14 feet, can thrive in rocky soil once established. Another recommended using chipped tree material as a soil amendment, allowing it to decompose and enrich the substrate.
A rancher in Montana shared that his York rake, angled slightly, created long rows of rocks that could be scooped with a loader. He emphasized that dry ground conditions were essential for effective raking and rock picking.
A technician in Oregon suggested avoiding PTO-driven rock pickers unless the tractor had sufficient horsepower. For the JD 4720 (66 hp), hydraulic models were preferred.
Preventive Measures and Recommendations
Clearing rocky river land in Idaho for native grass restoration is a labor-intensive but rewarding endeavor. With the right equipment—especially a dozer, excavator, rake, and rock picker—operators can transform uneven terrain into a viable meadow. By layering organic material, managing irrigation, and selecting deep-rooted native species, the land can be rehabilitated into a thriving ecosystem. The view of Mount McCaleb in the background only adds to the sense of purpose and beauty in reclaiming such ground.

Terminology Notes
- York Rake: A tractor-mounted rake with angled tines used to gather rocks and debris into windrows.
- Stone Picker: A mechanical implement that lifts rocks from the soil and deposits them into a hopper.
- Native Grasses: Species adapted to local climate and soil, often with deep root systems that improve erosion control and biodiversity.
- Topsoil Layering: The process of spreading nutrient-rich soil over a prepared surface to support plant growth.

Recommended sequence:
- Use the CAT 308 to uproot cottonwoods and stack debris
- Employ the D3 dozer to push gravel and rough-grade the surface
- Attach a York rake to the JD 4720 to gather rocks under 9 inches
- Rent or borrow a stone picker for deeper rock removal
- Spread chipped wood from cleared trees to aid organic breakdown
- Add topsoil where needed to support seed germination
- Install above-ground irrigation for the first two seasons

Preventive Measures and Recommendations
- Test Soil Moisture Before Grading: Dry conditions improve traction and reduce compaction.
- Inspect Rock Picker Compatibility: Ensure tractor horsepower matches implement requirements.
- Use Windrows for Efficient Cleanup: Rake rocks into rows before collection.
- Chip and Reuse Tree Debris: Spread as mulch to aid soil development.
- Monitor Irrigation Coverage: Native grasses need consistent moisture during establishment.
