The Stringybark trees on YackaYacka at Littlehampton are some of the more easterly that I've seen around this area. They tend to grow in the higher rainfall areas of the Mount Lofty Ranges.
Over the last 2 to 3 years there have been increasing numbers of them dying on my property and why that is I am not sure. I thought initially it was because of the preceeding exceptionally dry years but the trees continue to die even in a wet year such as the second half of 2010 into 2011.
 
8/3/11 - Advice from the Native Vegetation Council

 The first section of the property where I began planting was above and into an old quarry that was in the south western  corner of the block. The plants I selected were native plants with the aim of creating an understory. I used to work away a lot at the time (2 weeks on, 2 weeks off) and it was hard work at the time given the type of terrain in that small area, but the reward was in seeing the growth of the plants.

Something I always find interesting and stimulating is Seth Godin's Blog. Always thoughtful, it provides new insights into thinking about things and I find that it deals with a world that some people are already living in, some people are about to enter (willingly and unwillingly) and a world that is inevitiable.
