Cards in this set: Term Ecological Development Definition Process of environmental change by organisms. Term Primary succession Definition Pioneer species colonize newly exposed area (lava flows, glacial retreat, dried lake bed). Term Secondary succession Definition The community changes after disturbance (fire, hurricane, mud slide, logging, etc.). Term Climax Community Definition Community that seemingly resists further change. Term Restoration Ecology Definition Seeks to repair or reconstruct ecosystems damaged by humans or natural forces. Active manipulation of nature to re-create species composition and ecosystem processes as close as possible to the state that existed before human disturbance. Term Remediation Definition Cleaning chemical contaminants from a polluted area by physical or biological methods Term Reclamation Definition Severely degraded sites-- open-pit mines or large-scale construction Term Re-creation Definition Attempts to construct a new biological community Term 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) Water Term followup Definition Monitor Remove non native species revise
