Re: Crikey ! 90m in 79 years

As quoted by Brett from down under. https://victoriasgianttrees.weebly.com/tall-and-big-tree-news.html One thing has proved consistent in landscape and urban forest, that fast growing is on par with weak trunks and limbs. And storms hammer on the weak trees. Usually, the trees I kept track of that ...

Re: Fastest growing tree on the planet?

Bob and Brett, There is at least one 2nd growth douglas fir of similar age class that is over 90m. Douglas fir are capable of sustained growth rates approaching e. regnans. Thanks for noting that Michael. I was trying to search in that regard the other day, recalling something along those lines, bu...

Re: Crown crowding...

As a stand develops, say from a disturbance that cleared the area, there comes a stage where the crowns compete for light and attain crown closure. Almost. Looking up from underneath such a stand, one can often see 'corridors of sky' around the crowns. Screen Shot 2018-08-27 at 1.38.11 PM.png This ...

Re: Fastest growing tree on the planet?

Brett, I realized that you meant this is a tree with the fastest height increase you are aware of. Did you measure it's girth and volume change to know whether it's the really the fastest GROWING tree on the planet? Any idea how much volume this tree actually gained? Either way, sounds like a nice s...

Re: The tale of the tallest common juniper

For comparison, "The Bennett Juniper's height is 78 feet (24 m) feet with an average crown spread of 56 feet (17 m). The diameter at breast height (4.5 feet (1.4 m) above ground) is 12.7 feet (3.9 m). This gives it a total of 573 points by the American Forests formula for measuring "Big Trees", and...

Re: Northern California Redwood Forests - Not That Old?

Mario, That is an interesting question which I've often pondered, we are a part of nature, so aren't we entirely "natural"? I would say no, one of the main reasons being that we're so disconnected, mentally and physically, from nature,. Myself, I have certain beliefs including God. But if I answer ...
