To be mathematically correct, carbon sequestration has to be a negative number?
Herbert Yancey
32:12
Is the "Average Acre of Forest" in Vermont, northeast, US, globally - great to get some context on this metric.
Paul Renaud
32:14
A 10" diameter maple tree has sequestered a Metric ton of CO2e
Gary Fish
33:34
I assume C storage in Maine is lower because of a shorter growing season?
Leah Cook
34:27
Hey Gary, I'd assume it's do to relative youth and softwood stocking of our commercial forests.
Kenneth Laustsen
34:29
No , it is due to lower average stocking and younger forests
Robert Seymour
34:51
Neither. We cut more of the increment.
roger dziengeleski
35:26
Harvested trees converted to solid wood products are not measured as a carbon sink?
Jake Metzler
35:49
Roger - not "in the forest" which is what that map showed.
Amy Shields
36:18
apologies if this was answered at the start, but will we receive the recording of this (and future) sessions?
Karen Bennett
36:21
What would adding the solid wood products to that number add?
Amanda Bunce
37:46
I understand recordings will be sited on northeastforestcarbon.com after
Kenneth Laustsen
38:20
it is additive, but it is also decaying every year, paper has a very short life, solid wood has a longer life, and wood in landfills, also has a long life.
roger dziengeleski
38:47
Products produced from the forest are a part of the forest. If the limit is arbitrarily set as forest acres only, we are not getting a complete picture of forest carbon?
Paul Renaud
40:19
@roger dxziengeleski, it is important to distinguish between annual cycle and life cycle emissions. Your statement on forest products is correct on a life cycle basis, but not necessarily on an annual basis.
Amanda Bunce
41:31
Solid wood products, or long lasting wood products, are not usually counted as storage when we talk about it in presentations like this, but I’ve seen this create a lot of confusion, as it seems to be doing right now. This is especially a problem when talking to non professional audiences. I think we need to get more specific when we talk about carbon storage and carbon sinks, but it’s also harder to measure carbon stored in products, versus what’s stored on an acre.
Gary Fish
43:33
Aren't younger stands sequestering carbon at a faster rate than mature or over-mature stands?
denny gallaudet
44:01
The FVS carbon module provides a nice summary of these in and outs for the forest being modeled. There is pretty good consensus on rates.
Kenneth Laustsen
45:23
Another confusing topic, yes, young stands sequester more on an annual basis, while mature stands contain larger amounts of stored carbon
roger dziengeleski
45:48
Just worried a limited analysis of the forest carbon cycle will lead to management decisions based upon incomplete information - especially if product carbon sinks or substitution of forest carbon for underground (fossil ) stored carbon.
roger dziengeleski
46:25
are ignored.
Matt Kelly
46:37
She is talking about harvested wood products right now.
Elisabeth McLane
47:42
Forest carbon pool pie charts.... why are sequestration values positive for deadwood etc? They would be emitting carbon not sequestering, yes?
Amanda Bunce
49:25
Yes, dead wood emits carbon, but do they also send carbon back into the soil?
Amanda Locke
49:59
How is live tree carbon storage in old growth forests affected by disturbance? Does the accrual shown in your graphs still continue, or is it offset by carbon lost to disturbance?
Elisabeth McLane
50:11
Bill Keaton shows only 200 CO2e/acre at 400 yrs but the other chart shows 200 at 125 yrs....
Thomas Ebert
51:40
Any info about soil carbon loss from forest access roads and trails or heavy cutting?
Brian Schweiss
52:10
we always take an even aged perspective on carbon over time but what about an uneven aged system.
Kristen Murphy
55:54
Will the slides be distributed?
Carl DuPoldt
56:14
A climax forest appears to be an equilibrium state for Carbon and the rest of the natural processes. All natural process trend toward an equilibrium condition. So, the goal should be to maintain the equilibrium in natural . Any thoughts?
Charles Levesque

slides and recordings will be made available to everyone

Brian Woods VT DEC
58:25
@CarlDuPoldt depends on who's goal you are talking about
Amanda Locke
01:00:04
Is carbon stored in an individual tree affected by growing conditions (open-grown vs. closed canopy forest)? If so, are there different allometric equations for open-grown vs. forest-grown trees?
Amy Shields
01:02:52
Would like to hear elaboration on the topic of stored carbon within produced goods within this series. Its an element that is largely missing from forest carbon planning. The fact that its harder to measure carbon stored in product versus per acre seems to represent a necessary field of work if we are going to optimize forest carbon, forest health and still support the forest products industry that's necessary to implement forest management practices (and to provide the wide variety of wood products used by society)
Carl DuPoldt
01:05:11
Any thoughts of Carbon Science on the Soil Food Web?
Brendan Prusik
01:05:31
As trees decay, is that carbon released into atmosphere, added to soil carbon, fungi structure or something else
roger dziengeleski
01:05:49
It seems this program is well designed if the forest management goal is to maximize carbon on a forest or forest acre. It should not be used to fashion governmental rules and regulations that are intended to address the forest's role in climate change in general. Great for selling carbon credits though.
Carl DuPoldt
01:06:18
Carbon Science contains lots of variables. Model complexity. Any thoughts?
Carl DuPoldt
01:07:22
Any thoughts on the impacts on Carbon Sciece from clear cutting?
roger dziengeleski
01:08:01
Will do.
Todd Ontl
01:08:06
Carbon implications of decomposition can be controlled by the type of fungi decomposing wood. White rot fungi decompose all components of wood, but brown rot fungi
Todd Ontl
01:08:39
...are selective in what they decay , and can contribute to more carbon left and input into soils
Carl DuPoldt
01:09:42
So, Carbon Science is a slow process and does not work as fast as humans would like. Any thoughts?
Susan Stein
01:09:56
Where can I find data on carbon sequestration and flux over time for managed forests?
Kenneth Laustsen
01:10:33
Smith et al, 2006 is a good source
Amanda Bunce
01:11:45
I’m seeing a lot of great citations on the diagrams including Smith 2006. Hopefully presenter will share a complete list of sources?
Charles Levesque
01:12:10
slides and recordings will be provided to all
Carl DuPoldt
01:13:56
So, iin conclusion, we need more green infrastructure, particularly in our urban areas on the planet. Any thoughts?
Russell Wilmot
01:14:53
Interesting, any links on this Carl DuPoldt?
Carl DuPoldt
01:16:09
One huge input regarding Carbon Science, would be to reduce destruction of the rain forests. Any thoughts?

Outstanding presentation; great illustrations; clear delivery. THANKS!!
Greg Mikkelson
01:18:06
Flux at time 0 should be hugely positive, since that’s when a disturbance emits huge amounts of carbon. I also wonder whether it makes sense to credit wood products for storing carbon. For example, if you build a house with the wood it takes up space and therefore prevents photosynthesis from occurring in that space.
Helen Johnson
01:18:08
Would you please discuss carbon flux in soils due to compaction? thanks!
Patricia Czora
01:18:09
I understand from Suzanne Summer's TED Talk that Canada's clear cutting results in greater deforestation than Amazon ram forest clearing g

Bob Leverett et al. have recently published a great paper on this very topic (Do old growth stands continue to sequester and store C?) and have found that indeed they do.
Geoffrey Jones
01:27:58
What age are you using to determine an OG forest?
Ralph Baker
01:28:17
OG is usually defined as >125 yr
Tim Stout
01:29:59
Thank you Ali and Charlie; Remarkable level of detail

Greg Mikkelson
01:30:25
Sequestration continued indefinitely by very old-growth forests is how coal formed millions of years ago.
Mark Dillenbeck
01:30:34
Is the probability of major mortality events (e.g. hurricanes, insect infestations, etc.) a factor in estimates of carbon sequestration projections?
Thomas Worthley
01:31:00
Southern New England has numerous second growth forests that are about at that 125 year-old point, and do not approach old growth characteristics by any stretch.
Kevin Lemire
01:31:14
Aren't there old growth forests which can be assessed in inoperable/inaccessible areas? I see a lot of acres that have not been managed for these reasons.
Ralph Baker
01:32:00
Soil carbon can be lost as a result of harvesting, which doesn't seem to be reflected in your slides. I gather you'll get to this next week.
Ralph Baker
01:33:11
Kevin: Yes, most of the remaining OG forests are indeed in those kinds of inoperable/inaccessible areas.
Carl DuPoldt
01:33:47
Carbon Science makes a good case for the food forest = permaculture. Any Thoughts?
Michael Mauri
01:35:50
I believe the Leverett et al paper talks about individual old trees, not old forests. Right?
Ralph Baker
01:36:20
That is correct, but they also speak to the implications for stands.
Elisabeth McLane
01:36:37
Thanks Charlie!
Russell Wilmot
01:36:41

Carl DuPoldt
01:36:48
Will Certificates of Attendance be available?
Amanda Locke
01:36:54
Bob Leverett and his coauthors on the linked paper are well-known to support an agenda of a no-cut approach to maximize carbon storage in New England that is not supported by most forest research in the region.
Michael Mauri
01:37:05
I think that is why the old forests keep accumulating more carbon on the Keeton 2011 graph, but they do it at an ever-slowing rate, right?
Ralph Baker
01:37:05
Thanks very much for putting together and offering this series!
Elizabeth Cushman
01:37:12
👏
Norman Pattison
01:37:20
Thank you
Ralph Baker
01:37:52
Michael: yes, that's correct, but once removed through harvesting it would take a very long time to recover that stored C.
Ronald Frisbee
