approaches
Approaches
  • 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

slide6

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

Different damage, different intervention

Mining Operation

Logging

Bare rock, toxic levels of heavy metals

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

slide9

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

slide14

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
slide20

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.
