- Forest Conservationist Michael Ahr with West Multnomah Soil & Water Conservation District walks us through the benefits of forest thinning and provides tips on selecting trees to cut to improve the health and productivity of your forest.
Well this is Going to be very useful to be aware of in yhr near future, happy to hear good info from people with experience in their domain
Great educational video I've been thinning unhealthy trees mainly crooked pines that were chasing sunlight and leaving the young hickories that have more potential for the future. My woods have alot of scrub oak that competes with straighter hickory saplings. Mature hickory trees are uncommon in my woods. I hope to change that with my thinning practices.
Thx for sharing. I never would've thought to leave the piles of cut trees as habits for them wild thangs :)
thinning is the correct way to harvest wood sustainably.

another option is to fall your trees along contour patterns. it leaves the trees to serve landflow and ecosystem services with minimal labour time.
We don’t bunch our plants together in our vegetable gardens why would having trees all bunched together be a good thing.
A very good video thank you! The big problem with logging is the removal of organic material. By leaving habitat piles or logs we are enriching the soil and making it better able to retain moisture thereby reducing fire severity. We must also remember that treated Forest burn with greater severity then protected or otherwise UNLOGGED forest.
Well no, you have things a bit backwards here; let me explain. The problem is monoculture which destroys the soil. What is soil? Most soil is built from bacteria/microryzal fungi, sequestering CO2 and CH4 out of the air which is often from decomposing plant matter, but not majority(except in CH4's case this is ~100% true and is swallowed in top ~4cm of soil). Bacteria/Microryzal fungi are living creates who need a MULTITUDE of food sources. In this case, their food source are the Different hydrocarbons secreted/decomposed by Different species of plants be it tree, shrub, annual/perennial flower. If you only have one or two food sources the soil suffers.
As for fire, once again, you are offbase. Thinned forest are superior against fire for the above reasons which hold more water, but more importantly hold fewer DEAD standing trees which has been a massive problem due to Asian beetle kill off of trees especially on the eastern Cascade slopes recently in the Western USA. Of course the Eastern SLopes of the Cascades have always burned off repeatedly from what we can gather from historical evidence so the jury is still out to the true "best habitat" or best forest practice on Eastern Slope. We also must remember the peoples here originally burned off everything for Deer/huckleberry etc habitat and we honestly do not know what it looks like without human intervention as human setting fire for non evergreen tree habitat has been ongoing for thousands upon thousands of years..
@@w8stral you got some things right! Monoculture is horrible! Soil microbiomes matter and are dependent on a huge variety of factors. These fungi need food, rotting organic material supplies their fodder. Organic material on the forest floor insulates soil from temperature fluctuations. Freeze and thaw Cycles are tough on soil communities. Moisture retention is also greatly improved with rotting organic material on the soil surface. As for fire, you are right about indigenous peoples burning a lot, but you must remember that there is a big difference between burning a patch of forest and harvesting a patch of forest. Most organic material remains after fires, only the finer fuels have burned. It has not been harvested, instead the nutrients are simply recycled as they had been for millennia . An analogy that might be helpful to you is the Alfalfa farmer who repeatedly harvested his field without putting anything back into the soil. The soil would eventually be depleted . We need healthy soil. Healthy soil healthy trees! I think you would enjoy reading a book called Smoke screen. It was written by Chad T Hanson. He and a guy named Della Sala authored a study on forestry in 2016 or 2018. Their study is easily referenced by Googling" treated Forest burn with greater severity than untreated Forest". Enjoy the day!
No thanks, I'll go by the actual FARMERS who have to make $$$ not losers who do not OWN the land and do not have to make money, who have said alfalfa field who plant OTHER SPECIES with said Alfalfa and harvest the entire thing multiple times a year and have had their soil depth increase every year, water infiltration increase every year, water retention increase every year. It is the microbes that count, not the organic matter on top(its nothing to sneeze at but not important in grand scheme of things unless you are a salamander, mosquito, bee, moss, or frog. Increase microbe count via multi species roots excreting carbohydrates year round and you can harvest EVERYTHING you want above ground as the organic matter BELOW ground at depth is ever increasing.
As for forest: Thinning is far more important as allows light down to forest interior so one obtains a multitude of species. Go into any true OLD growth section and you get this.
Now in your favor: Something you did NOT bring up which you should have but either do not know, but many are now replicating across large areas of farmland: Divits. In a forest, one naturally obtains a NON flat surface from old stumps or uprooted trees or yes, even LARGE downed logs blocking water movment. This allows Dry/Wet Biomes in the exact same area so different species will have a WIDER range of growing conditions, flowering, fruiting, etc and this allows for greater beneficial insect species to thrive along with of course a wider array of plant species.
As for burning: well the jury is out regarding biochar other than it works wonders in DRY environments for retaining moisture, minearls, and fungi/bacteria. The jury is out due to non tropical climate requiring cold temperatures for a period of the year over large portions of the earth where this is being tried. For sure, Biochar in Tropical environment or other HIGH rainfall areas(leaching of minerals) has large benefits, but in areas with average rainfall it actually appears to IMPEDE plant growth. This makes sense as in GOOD areas, a roots ability to collect as much minerals from as much bacteria bringing them minerals is the limiting factor, not water or presence of bacteria/fungi to begin with who break down the rock obtaining the minerals in the first place. So, very dry/Wet conditions, biochar is good, but forest burning does NOT create biochar(it creates garbage which partially acts as biochar for a short period of time and then rots. Actual biochar does not rot)

@@w8stral no thanks? No thanks what? No thanks you don't want to read a book? No thanks you don't want to read a scientific study? Or no thanks you don't want to enjoy the day? Just because somebody studies something on public land does not make them a loser! You seem to be angry. You have some good knowledge. I wish you peace.
The problem I have read plenty of studies, and you quickly learn to look at the SLANT of their religion before bothering to read anything past the opening paragraph. "science" today has become more about religion than science. @@andyroubik5760
