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 change – Projected change (in years) in juvenile period between recent conditions (Product 1) and 2050 under RCP 4.5 (Product 3). Juvenile period metric is years to 50% of individuals in the population having flowered. Please see full metadata in 'Resources' section below.
