We present an evidence-based perspective to show how invertebrates, and the ecosystems they support, face major threats as fire severity and frequency intensifies in response to global climate change. Our capacity to make effective decisions about ecosystem recovery and restoration funding after bushfires is hampered by the lack of knowledge on how invertebrates are impacted by fire, directly and indirectly, and how invertebrate communities influence ecosystem recovery.
Unfortunately, invertebrates were often overlooked in media coverage and conservation policy responses. Other than a few charismatic threatened invertebrates, the discourse focused on the tiny proportion of animals that are most well-known and loved – vertebrates.
This is largely because there simply isn’t enough information or baseline data about most of our invertebrate species to talk with any certainty about how many invertebrates were lost or impacted by the fires. Listed threatened invertebrates are a rare thing, mostly an artefact of the taxonomic expertise and recommendation activity that was available for the relevant committee, rather than knowledge of new threats facing invertebrates.
I also collated data on which insect species are officially listed as threatened species in Australia. In Australia, we have a national list (under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999) of flora and fauna species that are considered threatened at a national scale. In addition, each individual state and territory has its own threatened species list under various state legislation. Continue reading →
Production benefits from invertebrates (other than pollination and natural pest control) are often overlooked in agroecosystems. There has been much more focus on the impact of insect pests. But invertebrates provide lots of other benefits in production systems. Developing sustainable farming systems is an imperative for our future – sustainable systems are those that produce food and fibre, while also enhancing human well-being and supporting ecosystem function through ecologically-sound management. Understanding how farms can be managed to enhance production via the benefits invertebrates provide is a key to sustainable agriculture. Continue reading →
