Don Leopold - Dendrology Videos

Hi Folks,

I thought you guys would enjoy this YouTube link.

Don Leopold, a professor of environmental and forest biology, has over 135 1-2 minute long videos on different native/non-native trees in the Upstate NY region. Many of the trees are commonly planted in the Eastern US. I like reading about trees, but sometimes it's nice listening to someone gab about trees too. Sort of like preaching to the choir.

Does anyone else have any good video links?

Very interesting.

I have a question though to the greater group - I happened to pick the red maple one to watch and he said red maple trees are dioecious (trees are male or female). I don't think that is entirely true. I can find references to them being "polygamo-dioecious" which is a less absolute way of describing them.

He also claims pinus ponderosa is the most important pine for timber in north america. I had always thought the eastern pines like p. strobus and p. taeda were more valuable for timber than any western pines because of superior growth rate and growing conditions.

Still, I do enjoy his vids. I stumbled upon them about a month ago and have watched many of them.

It's a good service he's done, I'm not discounting that. I had just not heard of maples being described that way. Although I have since found a reference that 'Autumn Blaze' is considered to be a clone with only male flowers, not sure if that is true either ....

My trees tagged as 'Autumn Blaze' have flowered and produced samaras in the past. All 5 of the larger ones I purchased did this. The flowering was very sporadic and the samaras were very small, much smaller than either rubrum or saccharinum. I have no idea if any germinated. I also have a smaller one in the 8-10' range that has not flowered yet.

Pinus ponderosa has become the most important timber pine as the eastern pines have been logged off - much wider distribution than the pines on plantations in the south. And Hortus Third says the genus Acer is 'commonly unisexual'

Psuedotsuga menziesii, Douglas Fir is the tree that produces the most timber for lumber. At least I read that somewhere a few days ago.
Here's some of mine.

Mike, he does mention something similar to that in his video of douglas fir.

Ah yes, he says "it is the most important timber species in the US"

Red maple comes in all male, all female and combinations.
