I remember that I learn how to distinguish the age of trees through its rings. But it is interesting that I’ve read about the gingko biloba. I couldn’t imagine that there is a specie, which is already existed at the age of dinosaurs. Thanks for the sharing the link of how to make Fairies with beautiful red leaf dresses, which I am going to check later.

Especially because the average span of an animal species is 5 million years, for one species to last 160 million years doesn’t sound right! But then you hear Bristlecone pines can live thousands of years, so maybe it’s the same number of generations.

I don’t think i’d known about the seasonal component to tree rings (or if I did, i’d forgoten). Thanks fro the reminder.

That video of climbing the worlds highest tree was amazing. How sad that there’s only 1% of those forests left.

An easy way to pick trees and shrubs is that trees mostly have a single trunk (but not always e.g.mallee) and are more than 5m high. I recently had fun teaching Little Eco how to work out the height of a tree. there’s some simple instructions here:http://www.landlearn.net.au/fieldwork/tree_measurement.htm. We used the eye and fingers method.
