Special Management Areas

What is a Special Management Area?

 

Benton County's Prairie Species Habitat Conservation Plan (HCP) protects five threatened and endangered plant species and two threatened and endangered butterfly species.  Because roadside right-of-ways provide a habitat similar to Benton county's original grassy oak savannahs, they also host populations of these plants and the butterflies that depend on them.

As there are special management designations and actions taken by Benton County to protect these areas, they are delineated as Special Management Areas, or SMAs

 

Does the County Manage SMAs Differently Than Other Roadside Locations?

 

Yes!  Especially Type 1 SMAs, which host higher numbers and densities of species covered by Benton County's HCP.  In general, the county avoids working in these area during the active growing season (Mar 1-Aug 15). 

Benton County also follows HCP guidelines for mowing, controlling noxious weeds, and for cutting, thinning or removing woody vegetation.  Soil disturbance is avoided to the maximum extent possible during road maintenance activities.

Two additional government agencies have enforcement authority over the Prairie Species Habitat Conservation Plan, and ensure that SMAs are managed according to the guidelines set forth in this plan.  The U.S. Fish and Wildlife Service has authority over protected butterflies, and the Oregon Department of Agriculture has authority over protected plants.

 

What Do I Do If There Is An SMA Near My Property?

 

Sensitive species within SMAs are protected under State of Oregon and Federal Laws. If you notice a white 'SMA' marker, you can help conserve these species by following some basic guidelines. The best thing to do for plants and species within an SMA is to not disturb them.

DO NOT:

  1. Park any vehicle in an SMA.
  2. Mow within an SMA.
  3. Apply chemicals, or allow chemicals to pervade an SMA.
  4. Pick plants or flowers, or collect protected butterfly species growing within the SMA.

DO:

  1. Refrain from conducting any activities within a designated SMA area from Mar 1 to Aug 15.
  2. Call or email Benton County Public Works with any questions or concerns about maintenance activities within SMA's.
