Ecosystems at risk: traditional and contemporary management

Question 1

traditional management strategies: wetlands

Answer 1

• custodians
• firestick farming
• boomerangs (mangrove tree)

Question 2

contemporary management strategies: wetlands

Answer 2

• education: guided tours, school visits, signage
• exclusion: buffer zones untouched
• tidal flushing gates: restore some natural tidal movement into the bird refuge
• leachate drainage system: oxidises water, ruins aesthetics, water –> sump, dried waste to landfill
• floating pollution boom: hydrocarbons (oil/chemicals) clog up roots
• pathways:

Question 3

approaches to management from best to worst:

Answer 3

preservation: public access denied
conservation: resource used sustainably
utlisiation: natural resources used, disrupt flora/fauna, replace ecosystem
exploitation: resources exploited without regard, flora/fauna devestated

Question 4

traditional management strategies: reef

Answer 4

cared deeply to not exploit

• setting size limits on fish caught
• seasonal hunting –> allow species to recover
• assigning sacred animal totems so groups would be responsible for survival
• maintaining small population levels to minimise stress on ecosystem

present:

• partnered with other gov. agencies
• ICPU (indigenous cultural liaison unit) helps to police, monitor and education

Question 5

contemporary management: reef

Answer 5

• GBRMPA (Great barrier reef marine park authority)
• on behalf of commonwealth government manage
• multi-agency approach –> many contributing
• QLD parks wildlife care for islands
• state gov. and local council manage land activities –> contribute issues with water quality, turbidity, urban development etc.

Question 6

contemporary management strategies: reef

Answer 6

• zoning: limits of human activities in certain areas
• bonds: use public moorings instead of anchors
• tourism: fee for educational programs, operators conduct EIS, strict management on islands
• Reef Plan: reinstating wetlands and riparian zones
