Australian alpine seed and seedling ecology

Alpine daisy

Description

This ARC linkage project examines the seed and seedling ecology of Alpine plants with an aim to conseration and management under climate change

The Australian alpine is critically vulnerable to climate change. Many alpine plant species are under threat of extinction. We will investigate how climate change will affect the reproductive ecology and demography of Australian alpine flora. Our novel approach will place particular emphasis on maternal or cross-generational effects on viability offspring success. We will also develop state-of-the-art seed banking methods, based on germination, dormancy and longevity studies, for conservation of alpine seeds in seed banks and botanic gardens. Outcomes will lead to effective monitoring, management and conservation of Australia’s alpine flora, and educate a wide audience about conservation of our national alpine biodiversity.
