Importance

of Native

Flora

Queensland is a biodiversity hotspot, and is home to an incredibly high diversity of native plants, many of which are found nowhere else in the world.

The state’s unique climate, ranging from tropical rainforests in the north to arid zones in the west, creates a variety of ecosystems that support over 8,000 plant species. This rich diversity is vital for maintaining healthy ecosystems, providing food and habitat for native wildlife, and contributing to the resilience of these systems against environmental changes.

Conserving Queensland’s native plants is crucial, as many of these species are under threat from habitat destruction, invasive species, and climate change. The loss of native plants can lead to the decline of entire ecosystems, affecting not just the plants themselves but also the animals, insects, and microorganisms that rely on them. Conservation efforts, including habitat restoration, legal protection of endangered species, and community-driven initiatives, are essential to preserving this natural heritage.

In addition to their ecological importance, Queensland’s native plants hold cultural significance, especially for Indigenous communities who have used them for food, medicine, and tools for thousands of years. By protecting and propagating these plants, we not only conserve biodiversity but also preserve the cultural traditions and knowledge associated with them.

Conservation challenges to saving our iconic native plant species

Our plant species are iconic and incredibly diverse with around 85 - 90% of Australian species endemic to the continent. Plants numerically dominate Australia's national list of threatened species, with 1,336 plant taxa listed as Vulnerable, Endangered, or Critically Endangered under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). The CSIRO Rare or Threatened Australian Plants ROTAP list has 5031 plant taxa listed within it which is not officially not recognised by any current Australian environment legislation but is an academic tool and is constantly under revision.

The research (Biological Conservation, Volume 260,2021) found that although there are three times as many threatened plants in Australia as threatened animals, they are much less likely to be the focus of monitoring.

Even know fauna conservation can be often directly linked to the vegetation environments they live in and conflicts between this and fringing urbanisation.

An Appraisal of the Queensland Flora Survey Guidelines for Protected Plants (Paul R. Williams and Bree C, Clouten) contains research data highlighting flaws about the standardised methodology when undertaking threatened plant surveys, which are essential to detect threatened species in areas undergoing development approval.

Rapid Development and Land Clearing: Queensland was one place reported to be undergoing the highest land clearing rates globally (sitting at 5th now apparently), furthering threatened species.

Queensland boasts incredible biodiversity, making comprehensive monitoring, data collection and conservation efforts challenging.

Reporting process to declare species as threatened has previously led some past species to be recognised as threatened too late. The process of listing rare and endangered species serves several practical purposes in conservation, but the difficulties of defining rarity and of comprehensively documenting plant distributions can lead to bias in the lists (S. Mclntyre). Data deficiency is another thing. Many uncommon or localised species now could slip through the radar leaving them potentially vulnerable (There is also the potential loss of the recognition of genetic or localised populations with the lack of monitoring). What might be rare today might be threatened in 5 or even 2 years. And it has happened in the past.

SEQLD planning framework and council planning schemes have made some protection laws exempt in areas gazetted for urban development in the past (not sure the status of it now) Lack of comprehensive surveying of species when going through the development approval process. It could be very likely that the minimum standards of surveying needs to be upped or exemptions be removed. There has apparently been a re address in environmental protection legislation. The general community often lacks information crucial to the conservation of the environment. Most do not have an appreciation and understanding of the importance of plants in the environment on top of their ecological importance. This lack of awareness can lead to insufficient government and public support for these related conservation efforts and funding for needed research.

There are many reasons to save our plants: resources, even oil was once from plants, food, or to support pollinations that are intertwined with the reproductive cycles of our food, pest control (its a billion dollar a year cost) medicines, erosion control, climate control, temperature control of soil, water, environmental structures and atmospheric, less evaporation of water for plants in the ground, healthy temps for aquatic organisms in freshwater bodies, local rain events can be affected up to around 70% from local plants through evapotranspiration, remediation of soils and biofiltration of water way pollution. Then vegetation plays all sorts of ecological roles dead and alive in ecosystems. Life has so many ecological niches that are all tied very closely together and we are part of that web of life. And plants are the very pillars to those ecosystems we so rely on for a quality life.
