Seed, live material and mulch sources on all National Forest System

Native Seed

The Forest Service has issued a new directive

(http://www.fs.fed.us/wildflowers/nativeplantmaterials/policy.shtml) for the use of native plant materials (from locally adapted genetically appropriate seed sources) in the revegetation, restoration, and rehabilitation of National Forest System lands. The policy helps achieve the Agency’s goals of providing for the diversity of plant and animal communities, and restoring native species and habitat conditions in ecosystems that have been invaded by non-native species. Plants that are adapted to these climates tend to be drought tolerant and their use preserves the biodiversity of the local plant communities.

Native seeds are more successful at out competing unwanted invasive plant species.

Ideally seeds should be sown in the fall not earlier than Sept 15th-before 2 inch of snow on the ground. Other alternative dates may be discussed with the botanist on a situational basis.

Mulch & Gravel:

Mulch and gravel must be from sources which are state certified weed free or approved by the district botanist. Excess local wood debris can also be chipped to use for mulch.

Wood mulch should be used when large areas of ground are exposed and erosion is a concern. Mulching ensures, moisture is retained for successful seed germination. Bark mulch should be placed at between 2-3 inch depth over the seed. Seeding may occur earlier than Sept. 15th if a bark mulch is placed over the seed. Straw mulch should be placed over the seed at depths of 1-2 inches or 1.5-2 tons/acre.
