This is actually something that has been quantified recently. And, it's been done for the whole globe! Really creative folks have used satellite-based LIDAR and RADAR to measure the forest canopy height and have provided maps that you can iteratively interrogate to see what the height of trees are anywhere:

For those of you who would like to compare the height of your forests to those favorites of Mitt Romney:

I've been visiting from Texas at the Indiana University campus in Bloomington for the past two days. Today, I walked across campus at lunch time and was asked five separate times by different volunteers if I would like to vote early. Four times were by volunteers at tables set up at strategic intersections, and once in a parking lot by a very nice lady driving a mini bus with a huge Obama poster on the side.

Whoever is coordinating the "ground game" in Bloomington is doing a fantastic job! If this effort is any indication of the work being done across Indiana, I'd say the state is going blue!

By the way, I'm voting early back in Texas tomorrow...one can always hope...right?

Louisiana's first line of defense...GONE!

The Chandeleur Islands are (were) a chain of barrier islands off Lousiana's southeast coast. Barrier islands form along wave-dominated coastlines and tend to protect the mainland from the heavy wave action and erosion associated with large storms. The Outer Banks of North Carolina are barrier islands that many in the USA are familiar with. The last few hurricanes that have directly or indirectly hit the Lousiana coastline (and Katrina most dramatically) have completely obliterated the Chandeleur Islands. This important first line of defense against the power of large storms is gone forever. The next storm to hit southeast Louisiana will be even more catastrophic than you can imagine...not that the last one didn't also fit this description.
