Category of habitats, based on species habitat preferences

a. Moist, leached sands.
b. Fertile loams.
c. Dry, sandy gravels of the eastern zone.

Seedbank

Snottygobble (Persoonia longifolia): a key component of the mid-story (< 5 m in height) of the jarrah forest in WA.

The combination of endocarp chipping and GA3 treatment is effective to promote seed germination, suggesting physical (mechanical) and chemical dormancy
+ Cool temperature is required to germinate
The longevity of seed is less than 1 yr

Smoke methods
Aerosol smoke
Smoke water, bubbling aerosol smoke through water
Concentrated smoke products (CSP), commercially available as Regen 2000 Direct, Melbourne - effective with low cost for restoration

Fire-related cues = heat shock + smoke + nitrate
Those cues are interacted to each other.


Rehabilitation

Tacey WH & Glossop BL. 1980. Assessment of topsoil handling techniques for rehabilitation of sites mined for bauxite within the Jarrah forest of Western Australia. Journal of Applied Ecology 17: 195-201

Study area: Jarradale minesite on the Darling Plateau
Climate: mediterranean type

Annual rainfall: 1217 mm (608-2169 mm)
Temperature: 8.4°C to 29.2°C

Three treatments on rehabilitation
Stockpiling

Unconfined heap approximately 10 m high for 2 yr was respread at the same average depth after mining

Direct whole-return

Topsoil was stripped to 40 cm and immediately respread

Double-stripping

Topsoil which had been stockpiled for 2 yr was spread onto a mined area to a depth of 40 cm and then covered with a 5 cm deep layer which had been freshly removed from the top 5 cm of topsoil of another unmined area
