Humans were part of the ecosystem, not adverserial, for millennia. Even when the Protestant work ethic started to encourage a destructive relationship, its reach was not ubiquitous and traditional management remained in many communities until transit and communication got super-sped.
Great to see/hear a film about pollarding. In Aragon, there are thousands of Chopo Cabeceros, Black Poplar pollards. If I am being picky, Would have been a perfect film with a voice over from a European person. Seems odd to hear an American chatting about this subject?
A great example is the exclusion zone around Chernobyl. Though not completely eliminating human habitation, we see species like wolves just doing their thing. It's been 40 years now....
Nice vid. I live in the Sierra Nevada of Andalusia. Here, if land is abandoned then it is not watered from the snow fed irrigation channels made by the Moors. The olive, almond, walnut and chestnut trees die back because of the ongoing drought. Therefore species diversity has lowered. I keep my land well watered and have wild flower meadows between the trees. Many species of butterflies, bees, beetles et al enjoy these meadows, many birds and other animals too. Wild boar love to wallow in the muddy land. Ibex graze the slopes above and below. Human interaction is needed on old established and traditionally worked land.
@@Theorimlig you are right (almost). The manuscript (including the research behind it), the illustrations and the animations are made by our project team. However, the voice-over actually IS AI-generated from our manuscript! We tried first with a human voice, but that was more difficult than expected, especially since none of us are native English speakers.
Fire does the same thing. Removes litter and debris. Prescribed burns are common in many parts of the U.S.A. In parts where they are banned, litter builds up to the point where a lightning strike causes huge catastrophic forest fires that cause billions of dollars in damage.
In principle, yes, but there are certain differences, particularly in the flow of nutrients. Mechanical removal of litter results in the removal of nutrients from the ecosystem (i.e. nutrient depletion in the soil), whereas controlled burning results in the mineralisation of organic material. This means that a significant part of the nutrients are released into the soil in an organic form and become available to plants. This may play an important role in determining which species respond positively to these two types of management. Unfortunately, there are still no comparative studies from one site that would assess the effect of both types of management on plant communities.

@@Norskinstituttforbiokonomi Yes, but in the U.S.A. most species evolved to take advantage of fire. Some pines will not even release their seeds without being subject to a fire. The great plains depended on wildfires to stimulate warm season grass re-growth.
You are missing you are missing the most significant fact about Pollarding. The height at which the original tree is cut off is the height at which herbivores cannot eat the fresh buds in countries like France this is the way to grow firewood and fodder out of the reach of hungry cows sheep goats. Then go features this unique landscape all the time
Yes, most often trees in Norway are also pollarded at a height that prevents sheep and red deer from reaching the fresh buds. However, we observe both geographical differences and variations based on tree species, highlighting that different areas have unique traditional techniques, likely related to their specific use of the branches.

Nice! Short, sweet and information rich. However over here in the UK fuel (wood, charcoal, whitecoal) may not have been the primary product of much coppice. Hazel coppice was common and very valuable, cut at around 7 years, so the desired produce was small diameter and used for a vast range of products from wattle room dividers and house wall sections to sheep hurdles, dry cooperage, crates and clothes pegs.
@@felixgrubert6864 Thank you! So do you. My output is done on no budget and as fast as possible on the 'editing' front with no script or anything, so it's nice that you say they are good. Best wishes from the UK.
Nice. Short and succinct. Here in the UK we have a similar tradition for similar reasons that has similar cultural and biodiversity value and which has undergone a similar decline. Unfortunately we don't have a similar effort to restore and maintain these old trees. Not wishing to intrude, but this vid shows some of the issues..... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LNlVu8f7cb4.html To the authors: boot this comment off once you have had a look maybe?
This explains why growing up in se Utah, our landlady had a Black Locust tree, it had a big trunk,and very tall, but considering its native habitat is the midwest and southern states, where it rains more than out West, well my mom planted some tomatoes, radishes and squash and the runoff of the water, permitted that ol' black locust to coppice, my mom left two of the shoots and they grew quite big, I wouldn't be surprised if that black locust is still alive and thriving after 42 years of moving from there.
If a society requires huge amounts of dimensional lumber for building purposes, then coppicing doesn't make a lot of sense. If what one is searching for are smaller diameter hardwood logs suitable for growing mushrooms, fence posts, making charcoal, barrel staves, tool handles, etc, then large scale, coppiced, mixed species, hardwood forests that are an integral part of a silvopasture system with multiple domesticated animal livestock species utilizing the coppiced forest throughout the 4 seasons makes eminent sense. The problem that I see with current day European countries where large hectare historical hardwood coppiced forests have existed for centuries is twofold. First, is that modern-day humans want *EVERYTHING, RIGHT NOW,* and coppiced hardwood trees aren't going to regenerate a new crop of harvestable logs in anything less than 8-20 years. Which means that a farming business that requires a dependable yearly income from a coppiced forest is going to require a sufficient number of hectares/acres planted sequentially across whatever time span that a particular tree species requires between harvests. Plus, a substantial amount of additional hectares/acres for the necessary wriggle room to account for seasonal weather irregularities such as too much precipitation or drought. Second is that there seems to be a worldwide anti-humanity, anti-historical farming, anti-Green Revolution farming movement in place that is tightly aligned with an anti-capitalist, pro-Marxist, pro-Socialist, pro-Communist, let's put right every single historical wrong movement where anything from the historical past is viewed as wrong, unjust, oppressive, patriarchal, etc. As a result of this 3 decades long push against the past, the large hectare historical coppiced forests in Europe are under attack as the Social Justice warriors attempt to redistribute those forest lands into hundreds of tiny plots of severe hectares each.
I believe the zealots that you described would much prefer the California approach to forestry, as in leave it wild and blame any unintended consequences on external factors.
There was a phase when I was living in an apartment with two cats, and I decided I didn't want to buy cat litter anymore. I went outside in the woods, and I dug up a bunch of leafy mulch and used it as cat litter. I'm sure the cats were surprised, but they did use it. Obviously, it wasn't as convenient and easy as just buying litter from the grocery store. But I would just go ahead and dump it over the hill into the woods, although I didn't mention this to anybody because I'm sure somebody somewhere would have freaked out about, OMG, animal poop in the WOODS! End of world! These are the same people who would rather put poop into a non-biodegradable plastic bag, and leave the plastic bag sitting there, thinking that a non-biodegradable plastic piece of garbage is LESS bad for the environment than the poop itself, drying out in the open air and then decaying.
Around my neighborhood is a park that used to be farmland. There are lot of willows that are pollarded. Volunteers maintain them. I never looked how they are shaped. now i will.
It’s tragic loosing these beautiful trees. The timber is very useful and has wonderful properties. I am wondering what tree species can be used as a substitute for ash in such uses as coach building and suchlike.
Thank you from a first time viewer and new subscriber! I have been interested in pollarding and coppicing for some time, still, I found things new and interesting in your video.
Leaf litter builds soil increasing fertility for the forest. Collecting dead fallen wood and burning that slowly makes biochar to scatter for more fertility. Work with Gaia.
