| 1. |
Survey site for physical characteristics: |
|
|
a. |
slope gradient and geometry |
|
|
b. |
geology and stratigraphy |
|
|
c. |
hydrology |
|
|
d. |
soils |
|
|
e. |
erosion and slope instability |
|
|
f. |
wave attack |
|
|
g. |
off-site influences |
| 2. |
Survey adjoining, undisturbed areas as reference of species occurring: |
|
|
a. |
strata (i.e., herbaceous, shrub, tree) |
|
|
b. |
density (plant per foot, acre, etc.) |
|
|
c. |
quality of existing plants for erosion control and slope stabilization |
|
|
d. |
age of plant community |
|
|
e. |
successional stage |
| 3. |
Develop specification: |
|
|
a. |
will structural element be necessary? |
|
|
b. |
suitable species; micro-site considerations |
|
|
c. |
numbers required of each species |
|
|
d. |
sizes available from commercial sources (native species, not cultivars) |
|
|
e. |
stock type (cuttings, bare root, etc.) |
|
|
f. |
contract growing required (may required a two-year lead time) |
| 4. |
Determine costs associated with initial planting: |
|
|
a. |
presence of exotic invasive plants |
|
|
b. |
site preparation |
|
|
c. |
cost of plants |
|
|
d. |
transportation |
|
|
e. |
costs of planting (fertilization, etc.) |
|
|
f. |
protection from animal damage (enclosures, repellants, etc.) |
|
|
g. |
irrigation |
| 5. |
Estimate costs associated with establishment: |
|
|
a. |
maintenance and monitoring |
|
|
b. |
replanting as necessary (90% success after 3 years) |
| 6. |
Estimate time to full restoration (considerably longer than establishment period, 10-15 years) |
| 7. |
Establish total costs of project. |
