To be mathematically correct, carbon sequestration has to be a negative number?

32:12
Is the "Average Acre of Forest" in Vermont, northeast, US, globally - great to get some context on this metric.

32:14
A 10" diameter maple tree has sequestered a Metric ton of CO2e

33:34
I assume C storage in Maine is lower because of a shorter growing season?

34:27
Hey Gary, I'd assume it's do to relative youth and softwood stocking of our commercial forests.

34:29
No , it is due to lower average stocking and younger forests

34:51
Neither. We cut more of the increment.

35:26
Harvested trees converted to solid wood products are not measured as a carbon sink?

35:49
Roger - not "in the forest" which is what that map showed.

36:18
apologies if this was answered at the start, but will we receive the recording of this (and future) sessions?

36:21
What would adding the solid wood products to that number add?

37:46
I understand recordings will be sited on northeastforestcarbon.com after

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.

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?

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.

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.

43:33
Aren't younger stands sequestering carbon at a faster rate than mature or over-mature stands?

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.

45:23
Another confusing topic, yes, young stands sequester more on an annual basis, while mature stands contain larger amounts of stored carbon

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.

46:25
are ignored.

46:37
She is talking about harvested wood products right now.

47:42
Forest carbon pool pie charts.... why are sequestration values positive for deadwood etc? They would be emitting carbon not sequestering, yes?

49:25
Yes, dead wood emits carbon, but do they also send carbon back into the soil?

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?

50:11
Bill Keaton shows only 200 CO2e/acre at 400 yrs but the other chart shows 200 at 125 yrs....

51:40
Any info about soil carbon loss from forest access roads and trails or heavy cutting?

52:10
we always take an even aged perspective on carbon over time but what about an uneven aged system.

55:54
Will the slides be distributed?

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?

56:33
slides and recordings will be made available to everyone

Consortium for Climate Risk in the Urban NortheastA NOAA Regional Integrated Sciences and Assessments (RISA) Projecthttp://www.ccrun.org/

58:25
@CarlDuPoldt depends on who's goal you are talking about

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?

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)

01:05:11
Any thoughts of Carbon Science on the Soil Food Web?

01:05:31
As trees decay, is that carbon released into atmosphere, added to soil carbon, fungi structure or something else

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.

01:06:18
Carbon Science contains lots of variables. Model complexity. Any thoughts?

01:07:22
Any thoughts on the impacts on Carbon Sciece from clear cutting?

01:08:01
Will do.

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

01:08:39
...are selective in what they decay , and can contribute to more carbon left and input into soils

01:09:42
So, Carbon Science is a slow process and does not work as fast as humans would like. Any thoughts?

01:09:56
Where can I find data on carbon sequestration and flux over time for managed forests?

01:10:33
Smith et al, 2006 is a good source

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?

01:12:10
slides and recordings will be provided to all

01:13:56
So, iin conclusion, we need more green infrastructure, particularly in our urban areas on the planet. Any thoughts?

01:14:53
Interesting, any links on this Carl DuPoldt?

01:16:09
One huge input regarding Carbon Science, would be to reduce destruction of the rain forests. Any thoughts?

01:17:03
Very nice presentation, Ali!

01:17:03
Thank you Ali, great presentation.

01:17:15
Thank you. Great presentation.

01:17:25
ALI SUPERB JOB and understandable...Bravo!!

01:17:28
Thank you Ali, great information

01:17:38
Thank you, Ali. I appreciate the quality and accessibility of your presentation. Looking forward to the next one!

01:17:53
Thank you Ali, great presentation!

01:17:56
Is there a references list for the references cited in the presentation?

01:18:03
Great overview and summary. Appreciate all the visuals. Thank you!

01:18:03
Outstanding presentation; great illustrations; clear delivery. THANKS!!

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.

01:18:08
Would you please discuss carbon flux in soils due to compaction? thanks!

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

01:18:10
Excellent, thank you Ali!

01:18:17
Thank you, Ali. A nuanced and comprehensive presentation.

01:18:33
Thank you for this compelling and comprehensive presentation. The graphs and diagrams were so helpful.

01:23:40
A great kick-off on a very complex topic, looking forward to the follow-up topics

01:23:54
Thank you for developing this series! As a landowner, I'm looking for information to help me better manage our forest for carbon storage and sequestration with the help of our forester.

01:24:51
Thank you.

01:24:57
Compare Jenkins and FIA methods for similarity of answers. Is there a significant difference between the two methods?

01:25:29
great presentation Ali!

01:26:01
Many thanks Aii

01:27:11
thank you, good day!

01:27:50
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.

01:27:58
What age are you using to determine an OG forest?

01:28:17
OG is usually defined as >125 yr

01:29:59
Thank you Ali and Charlie; Remarkable level of detail

01:30:04
Bob Leverett uses 150 years +......

01:30:13
Leverett et al. 2020, in bioRxiv preprint doi: https://doi.org/10.1101/2020.10.27.358044

01:30:25
Sequestration continued indefinitely by very old-growth forests is how coal formed millions of years ago.

01:30:34
Is the probability of major mortality events (e.g. hurricanes, insect infestations, etc.) a factor in estimates of carbon sequestration projections?

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.

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.

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.

01:33:11
Kevin: Yes, most of the remaining OG forests are indeed in those kinds of inoperable/inaccessible areas.

01:33:47
Carbon Science makes a good case for the food forest = permaculture. Any Thoughts?

01:35:50
I believe the Leverett et al paper talks about individual old trees, not old forests. Right?

01:36:20
That is correct, but they also speak to the implications for stands.

01:36:37
Thanks Charlie!

01:36:41
Thanks Charlie. Great job with this today.

01:36:43
Great stuff, looking forward to the next one.

01:36:48
Will Certificates of Attendance be available?

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.

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?

01:37:05
Thanks very much for putting together and offering this series!

01:37:12
👏

01:37:20
Thank you

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.

01:37:59
Thank you Charlie and Ali

01:39:23
Very informative. Thank you.
