Two pictures of three dead lower hanging branches on two nearby trees on the 'nature strip' at southern end of 13-15 Stokes St, Lane Cove North

A branch on LHS of prominent tree in above picture near the southern end of our property is lifeless - no evidence of leaves for a few years. 
A second dead branch (also evident in above picture) is approx 3 metres higher than the above lower dead branch. 
The second dead branch points north up Stokes St - no evidence of leaves.

The lowest branch (in the closest tree in above picture on our nature strip that veers twds the home units - located about 3 metres from our southern boundary) has been dead with no leaves for a few years.  It has a sign nailed about 1.5 metres above ground level  'Tree Replacement Program'.  Apart from this dead lower branch, the remainder of the tree appears healthy - exhibiting a lot of fresh green leaves.
