| Special values | 12.2.6: Potential habitat for NCA listed species: Boronia rivularis, Glycine argyrea, Macrozamia pauli-guilielmi. This ecosystem is also known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Late summer to winter. INTENSITY: Low to moderate. INTERVAL: 2-6 years. INTERVAL_MIN: 2. INTERVAL_MAX: 6. STRATEGY: Mosaic burning should be used to create some longer unburnt patches. Burning must be implemented while there is good soil moisture and mild weather conditions, using spot ignitions and slowly ignited, short drip-torch lines, to ensure fire intensity remains low to moderate. ISSUES: Intense fires during dry conditions damage grasses and promote dense shrub and small tree recruitment. Shrubs and small trees grow into dense ladder fuels that shade grasses and can draw flames into the canopy damaging eucalypt crowns. This promotes further dense shrub recruitment, which grows into dense thickets during subsequent long fire intervals, perpetuating the cycle. The loss of native grasses makes early-season, low-intensity fires more difficult to implement. Grass establishment in this ecosystem may be poor due to low nutrient status. |
