Re: Another opportunity to participate in carbon

Joshua- It's taking me a long time to get my head wrapped around this carbon sequestration thing, and it seems it'll be awhile before I get a really good grasp on it. That said, your comments of the 'world' after a disturbance, even stand clearing one, I think doesn't mean there is no carbon sequest...

Re: Another opportunity to participate in carbon

Bob- Lots to chew on there...one of the things I was supposing was that each successive "full cycles of 25 years" would deplete it's ecosystem and successively diminish to eventually a significant extent. The only commercial enterprise that would consider this would be either a mill that chewed fore...

Re: Another opportunity to participate in carbon

Bob- I might add that the planting matrix could run from 7-10' spacing, depending on the species...which I suppose also would have variable carbon sequestration rates...And the use of 30-40 year old stands presumably indicates at the very least, second-growth, and when dealing with industrial timber...

Re: Where does the trunk end?

Josh, Eric- Bob and I struggled with this "Where does the trunk end?", while working on the Measuring Guidelines. I think you're coming to grips with a solution for the problem you're facing and it's looking productive! Some of the citations that went towards the solution to the problem we faced "Si...

Re: The concept of fire rotation...

Bob- One of the hats i wore at Grand Canyon NP was that of field researcher. I was researching the effects of 1)no treatment, 2)thinning by hand and pile burning, 3)raking 'doughnuts around large old ponderosa pines, 4)broadcast control burning. An Americorps crew provided the 'person' power for tre...

The concept of fire rotation...

Fire rotation is a measure of the amount of fire in a landscape (the amount of time required to burn an area the size of the study area). The fire rotation statistic is best used for large areas that have mapped historic fire events. Fire regime - Wikipedia Recently a 'fire geek' friend of mine sent...

Re: One big tree versus a cluster of small ones

Bob-
Another scenario, certainly an extreme one, comes to mind. I've walked through stands of old-growth redwoods so thick and large that you felt surrounded by a 'wall of wood'...unable to see beyond say, 100'. Serious carbon there!

Re: Marsh-Billings-Rockefeller NHP and Billings Park

Joshua- For those Parks with fire-adapted forested ecosystems (like Sequoia-Kings, Grand Canyon, Yellowstone, and others), it is more accurate perhaps to view them in the context of ecosystem management, which is at the least the synergistic sum of the myriad parts. There are a few National Parks th...

Re: Marsh-Billings-Rockefeller NHP and Billings Park

Joshua- There are a number of NPS Parks that have/had forest management. Sequoia-Kings NP and Grand Canyon NP (I was a Restoration Forester in support of the wildfire mgmt. office of the Fire and Aviation Branch, until retirement in 2007) are both examples of Parks that interweave their wildfire man...
