Further; some threats such as increasing drought conditions due to climate change have the potential to exacerbate other threats such as the susceptibility of plants to insect herbivory (Koricheva et al. 1998 cited in OEH 2011).

Identify current and future habitat likely to remain or become suitable habitat due to climate change.

The species faces several fire related threats; including high frequency fire; fire drought interactions and fire disease interactions.

It is range reasonable to consider too frequent fire a threat to the populations as plants that germinate in response to fire need to develop to a stage where they are capable of producing seed and or coppice growth.

However; fire is required to break the hard coat of the seed and trigger germination and as such; a lack of fire or changes to the usual fire regime may have implications for successful reproduction (DPIE 2021).

Where appropriate; employ fuel reduction activities and other protective measures at strategic locations nearby to reduce the potential adverse impacts of bushfire on the population but ensure these are well planned and implemented and do not constitute an increased risk (e.g. through escape of planned fires); and are of low intensity.

Potential threats to the Genowlan Point Pultenaea include drought and grazing and trampling.

The recent drought may also have impacted on numbers.
