Will attendees get a Certificate of Attendance at the Conclusion of this webinar?
I think Airbnb & VRBO are a main culprit of current forest loss, due to development. What % of land purchases from out of state buyers in VT will end up being an Airbnb? Vacation housing should be dense & efficient
Invasive Plants + Climate Change = big trouble for NE forests, imo. On the edges of my woodlot, I see things like multi-flora rose, knotweed, and particularly the non-native bittersweet getting a jump on native plants early in the season, literally strangling / holding back tree growth. Look forward to more on this topic ...
How long was the longitudinal PEF study period?
Do you mean cutting cycle time between harvest entries vs rotation is time to grow your intended product?
PEF was about 50-55 years.
Gap size becomes largely irrelevant with appropriate modest retention (10-30%) within the gap. Early successional habitat is not the same thing as young forest of late-successional species.
Large trees: not to mention they may have more developed/extensive mychorrhizal networks
Bob: That 10-30 % retention in large gaps, is that based on BA?
Yes, BA works better than other metrics because its proportional to crown area (shading).
Robert Kobelia, CF
Do you have a recommended BA of "acceptable cull" that will compliment long term timber management?
There is an huge educational opportunity with landowners around deadwood and down woody biomass left after harvest, I talk to many landowners who want to "clean up" the forest
Alex - I agree about the educational opportunity. There are organizations already working on that education: Vermont Coverts: Wiidlands for Wildlife, Audubon Vermont, Vermont Family Forests, The Chittenden County Forester (Ethan Tapper) has done a great job of communicating this on his many forest walks and talks
Does the decomposition of deadwood into methane outweigh the benefit of leaving it , since methane is 20x more insular for the atmosphere? I expect there is a cross-over in time for benefit.
@alex Metzger, yes indeed. Much of what Ali is presenting matches with bird-friendly forestry. Birds are an accessible entry point and way for many landowners hesitant to manage their forest to become engaged.
My understanding is that methane is more common in anaerobic decomp, so most deadwood offgassing would be CO2... but I'm not an expert!
Can you comment on the importance of Leaf Area Index in eastern forests and how certain strategies maximizing leaf area index could be used to better offset very high soil respiration in young forests? (following Law et al. 2001 study in Oregon)
Can we get the recording of this presentation? firstname.lastname@example.org (Louisa Spencer) My son the brand-new forester would benefit.
When assessing/inventorying a property for enrollment in a carbon program, are there any considerations or values assessed for existing soil and BMP conditions seeing as it is 50% + of the carbon structure in a forest? Seems like the main focus is on tree species, densities, structure and health.
Sorry I was late
storm events also remove substantial amounts of soil and litter carbon from forest stores? i.e. snow melt or heavy rains.
Typically carbon programs do not include soil carbon stocks in the estimation of additionality compared to the baseline, essentially it assumes no change.
at best 60% of a tree can be put into traditional solid wood products, the opportunity is in products made from chips or other wood that has been processed and reconfigured into panels.
what is the effect of using wood scraps for heat and power generation since this is 'carbon neutral' over the long term ???
There is a good article in the May 2nd New Yorker on all-timber construction in Norway and elsewhere (but not in the US).
We already spend too much time writing plans,
sorry, any ready to use computer proframs available?
is there a soil color guide for estimating soil carbon?
Which website to find iTree tools?
Website for everything www.northeastforestcarbon.org
What effects, if any, do sugaring operations have on forest carbon? I would assume it is positive from a storage standpoint but is it negative regarding sequestration due to tapping stress?
If native birds take advantage of better silvicultural management (thinning / disturbance) to end up introducing an invasive plant to a new site ... is that a positive or a negative carbon-wise? Simplified concept, and obviously depends on specific site dynamics & time frames, but nevertheless ...
I would not consider the harvest deferral necessary to "extend harvest cycles" or implement "passive management" to cost $0.
Our imported wood: where is it coming from, mostly?
Most typically, Canada
Excellent presentation. Thank you.
My interpretation of the use of mats, portable bridges, and heavy upper material matting helps us to protect the soils pool in the roads, correct? Are we still reducing that pool with the possible rutting/compaction beneath the wood and the compaction? Is the largest priority to simply minimize main hauling roads and use of secondary roads only for one wagon load through the extensive road network?
Our clearcuts in Connecticut are more typically in hardwoods, which could impact the percentage in landfills.
Can you give any references or contact for folks that are exploring reducing our industry wide c footprint and using alternatives for our fuel/lubricant needs industry wide? This strategy will support our sustainability and public image. Thanks.
Thank you for a fascinating, comprehensive and helpful presentation once again!!
I second that. Extremely helpful and insightful.
If the daily growth rate is equal to or greater than the daily harvest rate across a forest landscape, does that not result in no loss of carbon stock at all?
Regeneration of the forest that the wood comes from is a critical factor in the consideration of wood as a “carbon neutral” source of energy.
Tipically when talking about bioenergy for the EU, we are talking about residues from primary production.

Thank you! Very interesting presentations.
Thanks for a great presentation
Thank you, Ali, excellent presentation.
Thank you Ali!
Thanks so much!
