Native plants

Approximately 1,500 species of native plants are found within the Adelaide and Mount Lofty Ranges (AMLR) including gum trees, orchids, ferns, grasses, herbs, lilies, and rushes. At the national or state level 121 are considered threatened and another seven are considered threatened within this region. Unfortunately some of these threatened plants have not been recorded within the AMLR for the last 20 years and it is likely that these species no longer exist here.

Threats to native plants

Some of the major threats to plant conservation within the AMLR region are:

  • Climate change, drought and severe weather – including the threat of long-term climatic change which may be linked to global warming and other sever climatic/weather events e.g. droughts, temperature extremes and storms and flooding.
  • Weed invasion – European settlement introduced many new species of plants to the Australian landscape. Many weed species impact or have the potential to impact on the growth, recruitment and survival of the native plants of the AMLR because of their ability to invade and spread rapidly within native vegetation; persist for long periods of time (including in the soil seed bank); out-compete native plant species and suppress the growth and germination of native plants; change soil chemistry; and alter habitats. They may also alter hydrological cycles, fire regimes and soil pH and nutrient levels. 
  • Water management and use – the regulation of rivers and diversion of water for urban supplies, industry and agricultural production have significantly altered flow regimes. Plant species requiring wet or moist conditions, and with narrow habitat requirements will be most impacted by water management and use. Impacts will likely be more pronounced during dry seasons and extended drought periods where human use tends to exacerbate already low levels.
  • Inappropriate fire regimes – whilst fire is a natural part of the landscape, changes to factors such as fire frequency, season and intensity can change habitat suitability for flora.
  • Grazing and disturbance by stock – grazing of stock can have positive and negative effects on habitats. Positive effects include stimulation of growth in native grasses and controlling weed abundance. Negative effects include changes to vegetation structure and composition and changes to the physical and chemical properties of the soil.
