There are no signs that Australian governments are taking this seriously. In Victoria, in spite of campaigns by environment groups, timber harvesting of native forests continues, further endangering many threatened species. The Regional Forest Agreements, which failed to protect threatened species, fulfil its legal obligations or to provide certainty to the forestry industry, are to be rolled over. Exemptions for the protection of threatened species under the EPBC Act are to remain in place. In March 2016, the Victorian government invited submissions to the development of a biodiversity strategy. Powerful Owls sometimes roost in the edges of pine plantations Protecting Victoria’s Environment – Biodiversity 2036, Photography © Gayle Osborne described as a long-term strategy for stopping the decline of Victoria’s biodiversity and improving our natural Governments seem to think that throwing a bit of money at environment so it is healthy, valued and cared for. some hard working, over-extended community groups will stop species extinctions.

The new go extinct, crushed by the weight of their responsibilities. strategy has two goals; Victorians value nature and Victoria’s natural environment is healthy. Also in 2016, there was a review of the Native Vegetation Clearing Regulations. It would seem that the resulting The plan concentrates on the value of biodiversity for updated regulations failed to improve the protection of humans rather than a properly constructed strategy to native vegetation.

In a 2014 article in Science, researchers argued that the word should become as familiar, and influential, as the concept of deforestation. In 2017 another paper reported that major population and range losses extended even to species considered to be at low risk for extinction. They predicted “negative cascading consequences on ecosystem functioning and services vital to sustaining civilization” and the authors offered another term for the widespread loss of the world’s wild fauna: “biological annihilation.” https://www.nytimes.com/2018/11/27/magazine/insect-apocalypse.html 2 Wombat Forestcare Newsletter - Issue 48 A Hobby is better than a pastime Prey is usually taken in flight and it is believed the Australian Hobby kills its prey with a bite to the neck, Words and images by Trevor Speirs while still in the air.

Hobbies also have a particular liking for the nests early days of European settlement.

My apologies to those among us who have a fear of all in the arachnid world, I understand if you decide to skip this article. I have a great respect for spiders and their potential to inflict a serious bite, but I do not fear them or dislike them. There are many occasions however when the unexpected appearance of a large spider, such as the huntsman that dropped off the sun-visor onto my lap while driving the car, has caused a high level of anxiety and a rapid increase in my heart rate.
