Hi and welcome to this issue of the Moss Environmental Newsletter. We have been hard at work over the last six months, putting together some great resources that are now available for free download on our brand-new website (www.mossenviro.com.au ). I am very proud of our Podcast “Beyond the Green Line” which was rated #1 in the Environmental Sciences category for Australia and South Africa and has seen a combined 500 downloads and counting, over the last nine weeks. We have had the pleasure of conversations with energetic, enthusiastic, and definitely-not-boring guests. Jump onto our website to find the latest episode about remote working from the bush, or subscribe to the whole podcast on Apple, Spotify or Google with the search item being: "Beyond the green line".
We often get questions about the biodiversity assessment process: What is BAM?, When is it needed? and What are the triggers?. Therefore, I am very excited to share our new Biodiversity Conservation Act info series sheet and handy infographic that steps you through the Biodiversity Assessment process for a development requiring vegetation removal. The info series gives you all the information you need to determine what report is required for your project, and the infographic is a handy flowchart that outlines the process once your determining authority has requested a biodiversity assessment be done. You can access the documents for free download on our website.
Now that you have listened to, and read all these interesting information, let’s take a walk outside…
The weather is starting to cool, and if you live in eastern Australia, you would no longer be forgetting to put your umbrella in your bag or car on your way out. All along the east coast we continue to experience increased rainfall, and cool daytime temperatures. This is because the El-Nino-Southern Oscillation (ENSO) is still firmly in La Niña. All indicators are favouring a return to neutral ENSO by early winter which would normally mean a return to average rainfall, however this year the Indian Ocean Dipole (IOD) modelling is showing a negative IOD playing tag with La Niña and developing through early winter which may continue to deliver above-average rainfall through to spring and beyond. For a greater understanding of La Niña, download this handy infographic by pasting this URL http://www.bom.gov.au/climate/enso/images/La-Nina-in-Australia.pdf into your browser
Since we are environmental scientists we deal with soils, water, and vegetation. Therefore, this continuation of a wet climate needs to be taken into consideration. For example, when managing the erosion potential on a construction site in a La Nina and negative IOD, you will need to concern yourself with greater scrutiny of the seed mix, topsoil management, soil ameliorants and on-going management of your revegetation. Quite often the seed mix specification has not been adapted adequately for your area or current seasonal conditions and will therefore, need the advice of an agronomist or rehabilitation practitioner to ensure you have a good mix of summer and winter growing species that can cope with higher-than-average rainfall and cool temperatures. Getting the mix wrong can be costly and leave you with exposed soils ripe for raindrop erosion. Groundcover, fast and enduring is your friend with the possibility of higher-than-average intensity rainfall occurring.
Just before I sign off for another months, I’d like to mention the great engineering team at the University of the Sunshine Coast. I had the pleasure of being invited along as a guest lecturer for 3rd year civil engineering students, to talk through the design of a type A and B High Efficiency sediment basins using the Sunshine Coast as our case study location. We had some really interesting discussions, and a very engaged audience. It was a lovely end to my week, that had me energised for the weekend to come.
Have a wonderful month, thanks for reading.
