ENTS,

Today I went on a short hike in Jackson Park which is located just outside of Hendersonville NC. While there I took a few mesurements of some interesting trees. The first one was a really nice Pitch Pine which was located in a grove of White Pines. I found out that trying to find the top of a rounded crowned tree can be difficult. I basically had to sweep around with the laser to find the highest point.

The next tree was a decent looking White Pine. I was impressed by how well the Nikon 440 laser was able to see through other trees to hit the top of the pine that I was measuring. I can see why many ENTS prefer the Nikon Prostaff rangefinder.

The third tree measured was a nice sized Chestnut Oak. Probably one of considerable age. It was located up on the side of a hill. I climbed up the hill and shot the tree with the laser and clinometer from near the top. I had to shoot though the tree to find the highest point. It was not where I thought it was. Once again scanning around with the laser proved useful.

The fourth tree measured was a nice holly that I had visited on a previous trip. This one proved the easiest to measure. I had a clean shot to the top and to the bottom.

Nice report and photo!

I do find the presence of both chestnut oak and relatively large holly
trees on the same site interesting: there's a local park down here in
Maryland that also features both trees mixed in with each other. Is
the soil in the area rather sandy and well-drained? Oddly, the park I
describe is in a flat, low-lying sandy area near the Chesapeake Bay,
so maybe it's the soil that matters more than the terrain (hills vs.
beach.)

The pines are nice - pitch pines are under-appreciated trees, and I
didn't even know how to ID them until I saw a clump of them
overhanging the parking lot of my apartment complex. I knew they were
not white pines since they looked different from the white pines in
the area; of course, once I realized that they were pitch pines, that
explained the habit of them dripping pine sap on the cars beneath
them!

Glad to hear that the laser rangefinder worked out well for you. One
of these days, I may get one of my own.
