Texte intégral

Based on the collated evidence, what is the current assessment of the effectiveness of interventions for climate change, extreme weather and geological events?

Unknown effectiveness (limited evidence)

● Replace nesting habitats when they are washed away by storms
● Water nesting mounds to increase incubation success in malleefowl

Unknown effectiveness (limited evidence)

Replace nesting habitats when they are washed away by storms

1A before-and-after study found that a common tern colony increased following the replacement of nesting habitats, whilst a second found that a colony decreased. In both cases, several other interventions were used at the same time, making it hard to examine the effect of habitat provision. Assessment: unknown effectiveness – limited evidence (effectiveness 8%; certainty 10%; harms 0%).

Water nesting mounds to increase incubation success in malleefowl

3A single small trial in Australia found that watering malleefowl nests increased their internal temperature but that a single application of water did not prevent the nests drying out and being abandoned during a drought. Assessment: unknown effectiveness – limited evidence (effectiveness 9%; certainty 10%; harms 0%).
