  • Re-creation or restoration of habitat
  • Ex situ conservation in zoos, aquaria, seed banks, cryobanks, etc.
  • Captive breeding for reintroduction

All measures of last resort


Ecological restoration: practice of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed

  • Building habitat for endangered species
  • Restore a dwindling community type
  • Revitalize ecosystem services
  • Reestablish site topography, hydrology, and soils
restoration ecology
Restoration ecology

Can trace its roots to Japan in 800 A.D. – 1600 A.D.

  • Loss of forest had led to erosion, lowland flooding, low crop yields
  • Leaders urged citizens to plant tree seedlings, eventually leading to nationwide forest restoration and management

Mining Operation


Bare rock, toxic levels of heavy metals

Still have mature trees and a rich seed bank on productive soil


Remediation: active removal of pollutants from the environment

Bioremediation: Use of plants and bacteria to accumulate heavy metals and toxins to restore soil health

remediation sulfur dioxide1
Remediation: sulfur dioxide

Vast area of mixed coniferous-broadleaf forest destroyed by sulfur dioxide emissions from a smelting facility nearby

Emissions killed vegetation, lowered soil pH, and altered soil composition


1) Applied ground limestone

Birch, aspen, and willow re-established

Elevate soil pH

2) Manually planted conifers

Eventual establishment of conifers

what to plant
What to plant?
  • Fast-growing invasives?
    • Pollution tolerant, good soil stabilizers, fast restoration
  • Native plant species
    • Restore original community
  • Seeds derived from local plant communities
    • Local adaptation

Fitness (survival x flower production) negatively related to genetic distance between source and resident populations

rat eradication
Rat eradication
  • Planning and environmental review
  • Lucy Island pilot project
  • Main eradication campaign in 1995
  • Follow-up and monitoring
effects on non target species
Effects on non-target species
  • Loss of ravens through secondary poisoning
  • Loss of ravens through primary poisoning
  • Brodifacoum residue detected in crows, song sparrows, bald eagles, but no population declines
effects on rats
Effects on rats
  • Rats took a total of 14,500 baits
  • Baits placed out in July 1995, by August 1995 no rats caught in snap traps, only activity seen near camps
  • Few cases of rats found in 1995, but by summer 1996, no evidence of rats.
