| Principles of Restoration |
|
Definition
1.Mimic natural processes
2.Plan for succession
3.Retain water and retain soil
4.Build soil |

Term
| Process of ecological restoration: preparation |
|
Definition
| Assess for contaminants.Determine species composition prior to disruption (refer to comparable “pristine” site.Set restoration goals. Remediate, (if necessary). Remove non-native (invasive) species |
|
|
Term
| Restoration: implementation |
|
Definition
Seed annuals (retain soil)
Control erosion: jute net (mimics roots); build swales
Mulch: organic material
Stops erosion, adds nutrients (builds soil), retains water
Plant perrennials and trees (fast and slow)
