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 ...

Re: New 100m tree species confirmed !

Michael,

Congratulations! The number of measurements taken is mind boggling. The amount of work behind those statistics, I can’t imagine.

functional circumference

NTS, Don Bertolette and I will be updating the American Forests Champion Trees Measurement Guidelines Handbook this year and we'll be producing a limited version for the general public next year. Other than tedious, the simple guideline presents few challenges. However, updating the main guidelines ...

Re: My 2021 High School Research Paper on Old-Growth Forests

Bee, Congratulations on your research paper. It is extremely well written and makes excellent arguments for protecting remaining old growth. Incidentally, Mary Byrd Davis was a good friend of mine. I worked with her on the old growth inventory that you cite. That report may still be our best overall...

Striped maple gets its turn

Ents, One of my favorite understory species is striped maple ( Acer pennsylvanicum ). It is best described as a small tree as opposed to a large shrub. Over the years, I've measured a few with CBHs of 40 to 44 inches. The tallest I have measured is (or was) 68 feet. I think Will and Jess went over 7...
