A study of the "whole" animal and its environment, including: population genetics
and dynamics, modelling population viability, feeding ecology (plant-animal
interactions), mate choice, dispersal, and the ontogeny of predator responses.
This project, now in its 8th year, has uncovered a series of potential reasons
for the continued need for remedial management action and has encouraged managers
to implement recommendations.
We uncovered six limiting factors that are likely to be still affecting recovery
of the species; there is scope for
- maximising genetic diversity in wild flocks through strategic translocations
of eggs and adults
- training captive-reared goslings in predator avoidance skills prior
to release
- intensive habitat management to enable the acquisition of adequate
fat and nutrient reserves
- intensive predator control
- community education
- further financial and community support
There are fewer than 900 Hawaiian Geese remaining in the wild. Future studies
will include Population Viability Analyses, social aspects of foraging ecology
and distribution, gosling diet deficiencies, and cultural transmission of habitat
shifts and local movements.
