By quantifying the length of time after fire for obligate-seeding plant species to become reproductively mature (the juvenile period), the risk of population decline under specific fire intervals can be delineated to inform local fire and conservation management. In this project, juvenile period data for serotinous obligate-seeder taxa across south-west Australia were collated from several studies. Linear models were then developed to estimate juvenile period based on measures of environmental productivity. These models were then spatially projected to the classic and drier Mediterranean agro-climatic class areas (Hutchinson et al. 2005) within south-west Australia.
JP - 2050 RCP 4.5 – Juvenile period as years until 50% of individuals in the population have flowered under future conditions (30-year period centred on 2050) with the RCP 4.5 emissions scenario based on a model featuring annual precipitation. (Fig 5 b) JP - 2× 2050 RCP 4.5 - Juvenile period as 2× years until 50% of individuals in the population have flowered under future conditions (30-year period centred on 2050) with the RCP 4.5 emissions scenario based on a model featuring annual precipitation.
