tree for id, mm1 27012012:
tall tree, binsar wildlife sanctuary near almora
saw these tall trees almost all the way down to haldwani which is where the mountains turn into plains
the bright yellow flowers were just beginning to bloom last week
wondering if this tree can be identified
may be Acacia decurrens
Many thanks ... for reviewing it and ... for taking the trouble to id it.
It is possible that this is Acacia decurrens but this is a Australian tree. The hills were covered with it all the way down to Haldwani. It appears to have spread like wildfire.
