Note:This publication has been superseded by the National Recovery Plan for the Abbott's Booby Papasula abbotti
Tall emergent rainforest trees which are reasonably sheltered from the prevailing south-east winds are required for nesting. Loss of nesting trees as a result of clearing for mining has resulted in a decline in the population. Furthermore, increased turbulence on the canopy of nest trees downwind of clearings has resulted in decreased breeding success and increased adult and fledgling mortality within 300 m of the edges of clearings.
1. To achieve downlisting of the species from Endangered to Vulnerable within 20 years, based on the IUCN (1994) criteria of population size and trends, extent of occurrence and probability of extinction.
2. To increase population viability by increasing the breeding success of birds affected by mine clearings.
3. To ensure that foraging areas are managed to maintain their value for Abbott's Booby.
|Specific objectives||Criteria for success||Actions|
|1. Form a Recovery Team and implement the Recovery Plan.|
|1. To continue to monitor total breeding population size and the breeding success of birds affected by proximity to forest clearings.||1. Estimated population size in subsequent surveys is not significantly less than the 1991 estimate.||2. Develop monitoring techniques to estimate the total population size and to compare breeding success, downwind, upwind and beyond rehabilitating minefields.|
|2. Breeding success of birds downwind of forest clearings not significantly different to that of birds nesting upwind of forest clearings.||3. Monitor overall breeding population size and distribution, and the impact of rehabilitation efforts on breeding success in areas affected by wind turbulence.|
|2. To ensure that all nesting habitat of this species is protected from clearing and degradation.||3. No further loss of breeding habitat.||4. Ongoing negotiation with all landowners to ensure protection of all known and new nesting habitat and of appropriate buffers around nesting habitat.|
|3. To produce a timetable for rehabilitating priority minefields and commence rehabilitation using that timetable.||4. Amelioration of wind turbulence downwind of the priority minefields identified by Carew-Reid (1987).||5. Ameliorate wind turbulence in all priority minefields.|
|4. To identify critical feeding habitats.||5. Critical feeding areas identified and effective measures taken, if necessary, to ensure the appropriate management of these areas for this species||6. Identify feeding habitat of breeding adults and any threatening or potentially threatening processes.|
*'Significant' is used in the statistical sense.
Protection of breeding habitat protects large areas of primary plateau rainforests which contains a high diversity of animals and plants. The rehabilitation program will benefit many other forest-dependent wildife, many of which are endemic taxa.
