Rucker Index Database

Ents, The phenomenal amount of effort that Brian Beduhn has expended compiling Rucker Indexes should not be left to float through the months as separate BBS posts. Martin Urbel, a database programmer, Brian, and I are conferring on a DB design that will capture Brian's work and provide a variety of ...

Re: Global Forecast Canopy Height - 2019 Interactive Map

Mark, I remain interested. The reason I kind of jumped the gun is that I frequently deal with government officials and academics here in the Northeast who are inclined to substitute sophisticated software systems for on-the-ground measurements. Integrating the two is an on-going project of mine. I'l...

Re: Global Forecast Canopy Height - 2019 Interactive Map

Mark, Erik, I don't want to sound overly dismissive of this canopy height tool. But I just applied it to an area in MTSF where the white pine canopy height is between 40 and 45 meters. Maximum tree height is 50.5 meters, but that is only one tree. However, the surrounding trees are, at a minimum, 40...

Re: Global Forecast Canopy Height - 2019 Interactive Map

Erik,

I couldn’t agree more. The danger with these gee-whiz tools is that they give a lot of people false impressions. The anount of misinformation flowing thereafter can compromise the value of the tool.

Re: We are TODs

Michael ad Bryan,

TOD developed in me in my middle teens. I am now trying to make up for the first 14 years. In my case it has developed into ETOD (excessive tree obsessive disorder). It is also known as EOTD.

Re: List of all known Old-Growth / Virgin forests in Pennsylvania

Russ,

I’ll proceed with caution. And I’ll ensure your caveats are included. I’m good friends with several Harvard scuentists, one of whom is from PA. He’ll definitely be interested.

Re: functional circumference

Don and Larry, As we move forward, it becomes more and more of a challenge to develop measurement methods that capture the essence of big in the big tree sense. Past American Forests practice was to ignore the complexities if the gob smackers and let the champion tree register devolve to more of a p...

Re: List of all known Old-Growth / Virgin forests in Pennsylvania

Bee,

A remarkable achievement. Do you have any objections if I show this post to scientists at Harvard Forest. Although, they can visit the NTS BBS and see it for themselves, most are not likely to do that. I'd like to make it easy for them.

Re: Indigenous Land Management & Pre-settlement Forests in Western New England

Joshua and Ray, Excellent discussion. Much of the banter about indigenous peoples fire-managing the landscape comes from forest managers who seek to justify their more intensive cutting practices. Their arguments are shallow and not fact-based. Nonetheless, the impacts of ancient cultures is a hard ...

Re: New 100m tree species confirmed !

Michael, Yes, I'd love the link. Thanks. I have a goal of trying to raise the awareness of forest biometrician acquaintances and friends here in New England on the incredible work that you all do out there. Back here they get wrapped up in managed forests with relatively young trees and tend to see ...
