April bird surveys


The relationships between some birds and their habitats can sometimes make them a useful species for identifying the health of an ecosystem.

'Golden Whistler' Reserve between Drouin golf course and the freeway
During April 2019, members of the Friends of Drouin’s Trees did bird surveys of fifteen sites in and around Drouin. 82 bird species were recorded with seven sites yielding more than 30 bird species in a one hour survey.
Wetland at Crystal Waters estate
Many ‘bush’ bird species – Eastern Yellow Robins, Brown Thornbills, Grey Fantails and Yellow-rumped Thornbills, etc – were recorded in good numbers at several sites, indicating the healthy remnant bushland patches that Drouin is fortunate to have.
Mistletoe Bird
Drouin’s pleasing variety and number of wetland areas too, mostly recorded a good range of birds – Grebes, Pink-eared Ducks, Golden-headed Cisticolas, Yellow-billed Spoonbills – indicating some healthy wetlands and marshlands.
Australasian Grebe
The Friends of Drouin’s Trees has undertaken the task of surveying Drouin’s bird populations twice a year to perhaps determine the effects that rapid urbanisation might be having on our wonderful natural environment.

Awesome autumn




“Autumn — that season of peculiar and inexhaustible influence on the mind of taste and tenderness — that season which has drawn from every poet worthy of being read some attempt at description, or some lines of feeling.”
Jane Austen 


“Delicious autumn! My very soul is wedded to it, and if I were a bird, I would fly about the earth seeking the successive autumns."
George Eliot


"I cannot endure to waste anything so precious as autumnal sunshine by staying in the house."
Nathaniel Hawthorne


“No spring nor summer beauty hath such grace as I have seen in one autumnal face."
John Donne


“Autumn…the year’s last, loveliest smile”
John Howard Bryant

Report warns millions of species threatened


In case you missed it, The Intergovernmental Science-policy Platform on Biodiversity and Ecosystem Services, IPBES, a panel of international scientists convened by the UN, has released a report that declares that species are declining at an unprecedented rate in human history.

Some declarations from the report which was formed by 450 scientists over three years, include:
           “Biodiversity is declining globally at unprecedented rates.”
“Species extinction is accelerating, with grave impacts on human populations around the world.”
“We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide.”
“The essential, interconnected web of life on Earth is getting smaller and increasingly frayed. This loss is a direct result of human activity.”
“Three-quarters of the land-based environment and about 66% of the marine environment have been significantly altered by human actions.”
“Urban areas have more than doubled since 1992.”

In urban areas, the IPBES report highlights, among others: promotion of nature-based solutions; increasing access to urban services and a healthy urban environment for low-income communities; improving access to green spaces; sustainable production and consumption and ecological connectivity within urban spaces, particularly with native species.

How are we doing in Australia?
“PM Morrison delivers a one finger salute to the IPBES report on the global (and Australian) biodiversity crisis” – Professor of International Law, Tim Stephens, University of Sydney.

“Since settlement, hundreds of species have become extinct in Australia, including at least 50 bird and mammal, 4 frog and more than 60 plant species. It is likely that other species have disappeared too, without our knowledge. More than 310 species of native animals and over 1180 species of native plants are at risk of disappearing forever.” – Australian Government Department of Environment and Energy. (Many ecologists suggest this statement highly UNDERESTIMATES the situation)

“Accelerating land clearing is increasing bushfires and droughts and compounding Australia’s extinction crisis.” – Ecological Society of Australia.

Australia is the only developed nation in the top ten worst countries for land clearing!

And in Baw Baw?


We could be doing better!
