Jackson County: Managing Vegetation Near Water

Can I remove or manage vegetation near a river or stream?

Short answer: Usually no—unless it’s approved.

  • Trees, shrubs, and vegetation must be kept in place by default
  • Removing vegetation, even blackberry, requires approval
  • When removal is allowed, native plants must be replanted

These rules apply to properties near rivers and streams in unincorporated Jackson County.

Common Questions

Can I remove Himalayan blackberry? 

Yes—but only with County approval, an approved restoration plan, and replanting with native vegetation

Can I mow or clear vegetation near the stream? 

No, not without approval. Clearing or thinning vegetation is not allowed by default.

Can I expand my lawn toward the river or stream? 

No. Expanding lawns into riparian areas is not allowed

My neighbors have lawns or cleared areas—why can’t I? 

Some conditions may have existed for many years, but new or ongoing vegetation removal is regulated under current rules.

Do I have to restore areas cleared in the past? 

Not necessarily. Restoration is generally required only when new disturbance occurs

 

What is a riparian area?

A riparian area is the protected land next to a river, creek, or other fishbearing water body.

In Jackson County, riparian areas are measured from the top of the bank:

  • Rogue River: 75 feet
  • Fishbearing streams: 50 feet

These areas include:

  • Trees that shade the water
  • Shrubs and understory plants
  • Roots that hold soil in place

They are protected because they:

  • Reduce erosion
  • Filter runoff
  • Improve water quality
  • Provide fish and wildlife habitat
Jackson Soil & Water Conservation District (JSWCD) can provide general, non‑regulatory guidance to help property owners understand riparian areas for vegetation management and restoration planning. 
Determination of the top of the bank for development or engineered projects is made by Jackson County and may require professional survey or engineering services. 

General Rule: Vegetation is protected.

Within riparian areas:

  • Trees, shrubs, and understory vegetation must be retained
  • Clearing or thinning vegetation is not allowed by default
  • These protections apply regardless of past conditions
  • Wildfire fuelbreak requirements do not override riparian protections

Is vegetation “grandfathered”?

No.

Jackson County does not have a grandfather date for vegetation removal.

  • Existing structures may remain
  • But vegetation protection applies under current rules, even if:
    • Vegetation was removed in the past
    • Lawns have existed for years
    • Past practices were different

Jackson County does not automatically require restoration of older impacts,
but new or continued removal is regulated.

When can vegetation be removed?

Vegetation removal is allowed only in limited situations and requires approval.

Invasive species removal

Allowed only if:

  • Approved by the County
  • Disturbed areas are replanted with native vegetation
  • A riparian restoration plan is approved by Oregon Department of Fish and Wildlife (ODFW)

Water-dependent or water-related uses

Vegetation may be removed when necessary for approved uses, but only with:

  • County approval
  • ODFW-approved vegetation plan
  • Restoration of disturbed areas

Riparian landscape / restoration plans

When vegetation is removed or disturbed, a restoration plan is required.

Plans typically include:

  • Existing vegetation
  • Areas of removal
  • Native replanting plan
  • Erosion control measures

JSWCD can help develop these plans as technical assistance.

Replanting guidance

A common rule of thumb used by ODFW:

  • 1 native tree or shrub per 64 square feet of vegetation removed

This is guidance—not a fixed requirement.
Actual needs depend on site conditions and goals.

Herbicide use near water

Herbicides are not automatically allowed in riparian areas.

If proposed:

  • County approval is required
  • ODFW review is required
  • Products must be used exactly as labeled
  • Drift or runoff into water is not allowed

Hiring a licensed applicator is strongly recommended.

What is not allowed

Unless specifically approved:

  • Expanding lawns toward streams
  • Clearing riparian vegetation
  • Dumping yard debris or compost
  • Removing healthy trees
  • Applying herbicides without approval
  • Clearing vegetation for wildfire fuelbreaks
  • Placing soil, gravel, or fill near streams

Who reviews and approves vegetation work?

  • Jackson County
    Reviews applications and approves or denies vegetation work
  • Oregon Department of Fish and Wildlife (ODFW)
    Reviews habitat protection and restoration plans
  • Jackson Soil & Water Conservation District (JSWCD)
    Provides technical assistance only (no permits or approvals)
