#1)  LiDAR for Brandy Wine Creek SP - Tallest is 168 feet

Postby M.W.Taylor » Wed May 24, 2017 1:13 pm

I had a request to process LIDAR returns for Brandy Wind Creek State Park. I get a number of trees over 160 feet, with the tallest emergent top being 168 feet.   The attached height banding is green 20m, yellow 30m, red 40m and white is 50 meters.  This is a tall forest with a nicely uniform canopy.

I see that there is a Tuliptree Nature Preserve at the far west part of the park. The tallest hits are not located in the nature preserve so I would guess that area has some age.

This LIDAR is for section just north of the park. See attached KMZ that links up the height banding with each crown.  You can load this image into your Garmin GPS and see the overlay on the Garmin's preloaded topographic maps. You can walk around in the forest with your Garmin GPS (or any GPS that accepts image overlay) and see the height of each tree around you, realized by the color banding.

Or add a GPS module to your laptop or tablet and see the image overlay in Google Earth with a position icon for rapid location of the tallest.

This is great! So many 160 footers. I hadn't spent any time looking north of the park but it doesn't surprise me that a 168' tree is in there. The whole area is impressive. It really is an amazing forest. I wonder how the average height here compares to a place like Cook State Forests in PA.

Michael,

Were these areas taller in general than the core of the park? It might be somewhat debatable depending on what part of the country one considers Delaware to be in...but the 168' tree would be the tallest northeastern hardwood. I suppose it depends on whether or not the tree in Longwood Gardens has grown any. That tree was actually 167' last I read but that was a few years ago.

John,  I got 167' on the software for the 168' hit but I added 1 foot due to the LiDAR set being 4 years old.  I am assuming 1 foot of growth.

I get only 161 feet for the 167 tree at Longwood Garden. The lIDAR is missing the tippy top and the ground level probably has some coverage that the LIDAR did not get through.

This is good news sort of. The 168' LIDAR hit near Winterthur might be well over 170'

This past Thursday John, a friend from Northern New Jersey and I headed to Brandywine Creek State Park.
We started at the parking area next to the Thompson's Bridge.
-Warning: this was not a scientific, accurate measurement type of day; we were intent upon climbing a good sized tree. As a mostly-retired arborist I miss being at height, so a recreational climbing was in order.

Using a static image of your KMZ file (I did not get the overlay to work on my phone with Google Earth Pro; I'll have to get a GPS) we searched for the two areas of 50 meter white banding on that side of the road looking for the tallest L. tulipifera in that area.
We found one tall one, that used to be co-dominant, but lost its partner a while back.
It has extensive hollowing decay, and is not long for the vertical orientation. Not safe enough to climb.

We found another less-tall tree with an accessible crown and climbed it for a better view of the valley.

After about an hour of being in the canopy, it started to rain, so down we came and John headed back to NJ as he had to leave early Friday for a weekend in the Berkshire Mountains.

After John drove off I hiked the entire area between the campground and the river looking for the other white color banding tree(s).
Never saw one that tall, except one that appears to have uprooted within the past year or two. A rough pacing off of the tree from the plane of the root plate up to where the top ends of branches had shattered gave me about 130 to 140 feet (thick underbrush made it a bit difficult). Pieces beyond where the force of the tree falling had splintered the top likely added another twenty feet or so. It's girth and width made me think this may well have been the other large tree.
