5 MANAGEMENT UNITS

MANAGEMENT UNIT 1 INVASIVE DOMINANT (TOP OF SLOPE) Phase One – Preparation and Planting, Late Summer/Fall  Identify weeds present and use eradication methods  Remove weed top growth leaving roots in place  Minimize soil disturbance  Install coir erosion control blankets over entire restoration area  Install deciduous and evergreen shrubs (no trees) Phase Two – Monitoring and Adaptive Management  Monitor during the growing season for the first year  Replace plants that fail and adapt species mix as necessary  Continue to monitor plant establishment for five years  Monitor for slope movement

MANAGEMENT UNITS 1 AND 2 No Work will happen in areas with slopes 80% and over.

MANAGEMENT UNIT 2 – STEEP SLOPES, INTENSE RESTORATION Phased Grid Cell Work  Coppice only previously coppiced deciduous trees leaving one healthiest stem in each tree  Remove 25% of canopy on other deciduous trees only if needed for light (May repeat in subsequent years )  Leave coppiced tree stems lodged against stumps, remove brush  Install coir erosion control blankets throughout cell  Install plants to average five conifers, two deciduous trees per grid cell with dense shrub and groundcover layers  Monitor for plant establishment for five years, supplement planting as needed  Monitor for slope movement
