| 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

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)
