5.3 Timing A schedule for the implementation of the Impact Mitigation Management Plan shall be developed once the timeframe for the commencement of vegetation clearing has been confirmed.
The activities will be undertaken in three main phases: • Phase 1 – Collection of seeds and plant material. • Phase 2 – Planting of tube stock
• Phase 3 – Establishment of a seed orchard at another location away from site. Provide seed and material for study, and for interest groups like Native Plants Queensland, Central Queensland University, University of Queensland, University of the Sunshine Coast.
Phase 1 works will be undertaken in stages to align with construction works.
There is no documented advice regarding the most suitable time of the year for planting of G. hockingsii tubestock. General advice provided in Commander et al (2018) is that the preferred time for planting is during months of higher rainfall (i.e. November – February) to lessen the chance of plant losses due to water stress. Moist soil also facilitates the process of digging planting holes for planting seedling tubestocks.
5.4 Management and Propagation Methodology The management and propagation methodology to be followed is detailed in the following subsections. The methodology will be reviewed following appointment of the plant collection contractor and confirmation of machinery available/suitable for the task. Pre-clearance survey G. hockingsii plants within the impact area will be assigned a unique identification code and marked with flagging tape when propagation material is collected from them. This propagation material will be where possible seed and scion (cutting material). 5.4.1
The following information will be recorded. • Salvage/Impact site, specimen identification code, GPS location • Maturity • Health • Evidence of insect and/or pathogen attack • Type of Material collected
