Reed College Canyon


Reed Canyon Enhancement Strategy

Native Plant Revegetation

When the management of invasive vegetation in a given area is under control, enhancement by addition of native plant materials can begin. Where proposed, habitat creation in the form of snags and downed large woody debris should be created / imported prior to planting so that access to the site is clear. The following is a list of enhancement elements to be considered, followed by specific plant community lists for revegetation of Reed Canyon.

Soil Preparation - Habitat Creation - Native Plantings - Plant Communities

Soil Preparation

Soil preparation will be based on what is found following the removal of invasive species. Some areas may require minor soil amendments, but it is likely only in limited circumstances.

Recommended Management Strategy:

  1. Upon completion of invasive species removal determine the levels of soil amendments needed, if any.
  2. Use only weed-free soil additives such as mature leaf compost, to reduce further invasive species contamination of the site.
  3. Use gypsum if dense soils need to be amended for better drainage of water.

Habitat Creation

Creating additional habitat at the site will require the import or movement of large woody debris. Habitat features should be added once invasive species are under control and before native planting are added.

Recommended Management Strategy:

  1. Maintain standing and downed woody debris on site for cavity nesters and as basking logs for turtles.
  2. Add bat and bird boxes throughout the site, on the edge of transition habitat areas.
  3. Import additional large woody debris if available and as needed.

Native Plantings

Planting of the different management zones will occur as areas are cleared of invasive species and appropriately prepared. Successful revegetation of the site will require proper propagation, installation, maintenance and monitoring of the existing and newly installed plant material.

Recommended Management Strategy:

  1. Planting is best during the late fall, winter, and early spring. Seed during the late summer/early fall or early spring.
  2. Heal-in plant material to site for several weeks prior to planting by placing it in the area in which it will be planted; propagate plant material on-site if there is interest in doing so.
  3. Provide topsoil mix in planting hole if soil conditions are poor; topdress all plantings with mature leaf compost to provide nutrients and protect from dry out (particularly in sunny locations).
  4. If beavers are an issue, surround plants with welded wire guards to keep them from damaging new plantings or larger existing trees.
  5. Provide erosion control as needed by seeding ground with sterile wheat or re-green or the native seed recommended. Some areas may require soil bioengineering techniques.
  6. Deep water plant material 5-8 times per summer for the first two to three years, or longer if needed.
  7. Weed around new plantings at least twice a year, and place additional mature leaf compost.

Plant Communities

The following is a list of suggested plants by their community type. Detailed information on the placement of these plants as part of the revegetation strategy is provided in the Implementation Strategy Section.
