Bush Crew diaries September 2021

Published on 27 August 2021

The Bush Crew planted running postman to save it from extinction.

Our species enrichment plantings at St Helena Bushland Reserve is long-term project that increases the population size of indigenous plants now in critically low numbers.

Indigenous plants and animals interact and have complex relationships with one another. Disturbances such as land clearing – resulting in fragmentation of bushland – and the effects of invasive plants, animals and diseases are key reasons why some indigenous species are in decline in Banyule and now at risk of local extinction.

Increasing the population size of these species through revegetation will help to slow or prevent local biodiversity decline.

Other specialised species such as indigenous orchids are difficult or impossible to re-establish back into bushland areas. For these species, it is imperative that we allocate resources to manage threats and look at ways that we can increase and enhance wildlife corridors within Banyule and surrounding municipalities.

This winter, at St Helena Bush Reserve, we have planted the following species as part of this project:

  • Pink bells (Tetratheca ciliata)
  • Common billy buttons (Craspedia variabilis)
  • Wiry buttons (Leptorhynchos tenuifolius)
  • Smooth flax-lily (Dianella longifolia)
  • Small grass tree (Xanthorrhoea minor)
  • Sweet hound's tongue (Cynoglossum suaveolens)
