Overview
Detailed knowledge of the distribution and abundance of Macadamia species has been acquired through field surveys conducted during the life of the previous Recovery Plan. This provides solid evidence that Macadamia species are sufficiently diverse, abundant and connected in the remnant landscape to persist in the short term if populations and habitats are protected and threats are mitigated through appropriate management. Key to achieving this is a coordinated, cross-tenure approach that ensures further loss of essential habitat within areas of key population clusters is avoided.
Weeds remain the single greatest threat to Macadamia species in the short to medium term, as they have the capacity to retard rehabilitation of degraded areas and in the worst cases, invade and transform intact rainforest habitats. In the longer term, impacts arising from habitat fragmentation including degradation, inbreeding and drift are likely to become more pervasive. These impacts will be exacerbated with further habitat clearing and loss of individuals or populations, particularly priority populations. Climate change is also highly likely to place many populations under additional threat through increased environmental stress and reduced reproductive potential. Loss of genetic diversity and/or hybridisation through pollen from orchard cultivars is also a potential medium to long term problem. Given these factors the recovery approach adopted in this Recovery Plan is to focus on outcomes that address short term goals whilst considering the medium- and long-term threats. For example, stratifying the identification of critical populations and habitats and the threats they face (based on short to medium term considerations), to identify those which are likely to be most resilient to climate change and have lower risk of contamination from cultivar pollen.
