Welcome to EcoRamblings®, an industry newsletter for people that are required to address or manage flora, fauna, vegetation or natural ecosystems within Australia. My name is Simon Cropper, Principal Consultant of Botanicus Australia Pty Ltd, and I have prepared this publication with the primary objective of educating natural resource managers, developers, councils, community groups and governing agencies about key ecological issues I don't believe are being adequately addressed within the industry. It is hoped that an improved understanding of these issues will raise industry standards and result in better conservation outcomes. Please note that future issues of EcoRamblings® will be published intermittently. Links to online copies of the newsletter will be published on this webpage. If you would like to be notified when new issues are published, click here to send an email with 'ECORAMBLINGS SUBSCRIBE' in the subject line.

• Q&A: An LGA Officer asked "What happens after 10 years to land being managed as an offset?"
• Q&A: A land manager asked "To rehabilitate a degraded site to it's floristic potential, is it better to manually reinstate the site with a mixture of native grass seeds, or should we just allow nature to take its course?"
• Q&A: An LGA Officer asked "Is it really possible to revegetate an area back to healthy and functional pristine bushland? What kind of time frame is needed? We talk so much about offsetting the loss of bushland with replanting. Are we really just wasting time and creating areas which will never be self sustaining and turn into weed scapes or monocultures?"

EcoRamblings®, Issue 3 (May 2007)

• Mis-representation of cost - An illegal practice.
• Dangers to outside workers - Lightning.
• Power, control and product branding.
• Q&A: "Should the ground watertable be lowered by up to 3 metres under salt marsh vegetation? I presume the saltmarsh would deteriorate in time without any remedial action, if so, when would the likely deterioration effects on the saltmarsh be evident and would you recommend an adaptive management plan be implemented to combat this deterioration?"
• Q&A: "What impact are the many blue gum plantations in Western Victoria having on groundwater levels for farmers who now have plantations next door to them? They want to know why spring fed creeks which run out of the blue gums, have gone dry for the first time in history."
• Q&A: "What sort of changes might we expect to see in our local grassland communities as a result of climate change and as land managers what should be our response?" Don't ask for financial advice, you won't get it! Common terms used in conservation.

• Targeted Priority Management.
• Q&A: Housekeeping - introduction to new community forum
• Q&A: An LGA Officer asked "Where in the Western District have naturally occurring Microseris lanceolata (Yam Daisy) been found?
• Q&A: An LGA Conservation Officer Asked "In relation to old remnant trees why can't an arborist report be sufficient in making a decision about tree retention? I have been told you also need an ecologist report. Can you clarify why this is the case?"
• Q&A: An LGA Conservation Officer Asked "What is the best time of year to monitor vegetation to ensure you get as many species represented on a site?"
• Q&A: Ann Lloyd McKenzie (President, Friends of Glass Creek Parklands) asks, "What is the best way to deal with a Ehrharta erecta (Panic Veldt Grass) infestation in an open forest revegetation area?"
• Q&A: A government officer in response to my discussions on the potential response of indigenous ecosystems to climate change in Issue 5 of EcoRamblings stated "Your thoughts resonated with me, though I reckon that the capacity of the landscape to respond to the rapid change we're likely to encounter is limited. And while the principles seemed sound, they may not prove realistic, particularly given the likelihood of weeds filling niches before Victorian species."
• Q&A: A local landowner explains "We live in the Otway Ranges and have been planting native trees and shrubs on a 10-acre section of a former dairy. The salt air environment has meant that plants have been slow in getting established however we are starting to see some good progress and the wildlife is returning. We are sighting black-shouldered kites, wallabies, echidna and more recently koalas. I have noticed that the koalas seem to be very destructive to young eucalypts, often breaking slender branches while reaching for the new growth at the top of the trees. In your view is this likely to have long lasting implications for the health of the trees? Else-where I have noticed that even more mature trees have been severely set back by Koalas and with the drought it is not clear how well they will recover."

• The long awaited results of the area estimation survey.
• Key Result 1 - Most people, regardless of training or presumed practice, have the ability to estimate cover to ±10% and that in general untrained people tend to over-estimate lower values compared to industry professionals.
• Key Result 2 - Only one third of the 54 respondents had cover estimation skills suitable to conduct either 'traditional' flora surveys or Habitat Hectare Assessments.
