Re: Global Forecast Canopy Height - 2019 Interactive Map

Mark, for identifying forest over 25m in height, it is good. And as your liDAR comparisons illustrate it does a good job at showing relatively higher or lower sections of a canopy within a given fairly level area. I'm certainly not expecting to use it to identify the tallest trees in this region. Th...

Re: Allegany State Park's Trackless West

Saturday 9/11 I made another exploratory visit to the Bay State Coves and then over the ridgeline to the Crick's Run drainage. Crick's Run turned up an area of very promising second-growth on a steep east-facing slope, but while the small area of hemlock old-growth and larger areas of mature hardwoo...

Re: Big Basin - Allegany State Park

Elijah, These productive slopes seem to go from about the 2,000' to 1,600' contours, give or take a little. The classic central "Big Basin" old growth area is a bit higher in elevation (2,200-1,800 or so), which I suspect is why overall heights are lower (white pine being the big exception) even tho...

Re: Global Forecast Canopy Height - 2019 Interactive Map

I was hoping that even if it doesn't display heights over 30m, that this would at least suggest which forests are relatively taller or relatively shorter. Unfortunately, at least in the region where I can compare to sites I've measured, I think it may be more influenced by terrain and other issues t...

Re: Frozen Head State Park, TN

Elijah, It's great to see a survey like this at a highly productive site in the Cumberland plateau, and especially the diversity of tall species. I mentioned on the phone before how the cumberland and allegheny plateaus are two segments of more or less a single formation, so you may have moved hundr...

Eastern Slope- Allegany State Park

In addition to the "Trackless West" and "Big Basin" portions of Allegany State Park, an area consisting of many small watersheds draining east or north into the Allegheny River wraps around the eastern and northeastern edge of the park. I've taken to lumping these together as the "Eastern Slope." Ge...

South Valley/Pine Hill State Forest and connected lands

South Valley State Forest is located in southwestern Cattaraugus County, across the reservoir from Allegany State Park. Pine Hill State Forest is just north of South Valley State Forest. Both are quite irregular in shape, presumably having been cobbled together from many separate parcels, and sectio...

Re: Harriman State Park, New York

Hi Rus, Thanks for your description of your visit. Driving past Harriman from time to time when I lived downstate I wondered about what tree potential it might have. You're not kidding about how heavily visited those parks in the lower hudson region can be, especially in these pandemic years. Often ...

Re: Big Basin - Allegany State Park

Recently I had the good luck to find a good ebay deal on a Trupulse 200x. My 200B has gradually gotten less sensitive- perhaps I pointed it a little too close to the sun too many times- and its reticence has somehow made tree-measuring less fun. The 200x, as it turns out, makes measuring even more f...
