The first photo here was taken early in 2007 - note the tree on the right, on its last legs, lots of hollows, broken limbs on the ground and sparse foliage. Compare this with the second photo that I took last week. See how the tree seems to have a new lease of life. The new leafy growth in the centre of the tree is quite amazing.
I'm wondering if the tree is enjoying the fact that the cattle that used to puddle around its base have now been removed, and that it is protected it from the prevailing winds by the trees that now surround it.
