Haven't a clue why youtube recommended this video for me, but I found it really interesting.
Hi Ken, I am glad you enjoyed it.
Thanks from Geoffrey
addictive..regreening the desert.. africa, china, australia
look at Mulloon farm institute videos from australia.. Tony Coote got Peter Andrews to help him
❤ divine intervention? ❤ Meant to be.
Someone might have mentioned his name. Or the area or something
Peter Andrews is a Aussie legend , look into him very interesting story . We should all be taking a big interest in his land care methods.
A genius of a man, Mr Andrews. Common, applicable sense to save our degraded land!
I have been applying this on the creek running through the land I am on. It definitely makes a difference when it rains.
Hi, I am glad it is making a difference for your creak.
Thanks from Geoffrey
In North America beavers are being used to regreen creeks and build wet lands.
Hi, yes I have herd they are using beavers. I guess they do a very similar job to the weirs.
Thanks from Geoffrey
Yes, but you could not controll them
I guess the closest thing to a beaver that Australia has would be the platypus.
They work really well for controlling gully erosion in culitvation. Just a word on design. Middle of the dam should be lower than ends so that when they overvflow water sticks to the middle and the downslope of the dam should be extended a bit to slow the water down and reduce undermining. Keep up the good work. Impressive
Was going to say that he didn't try his best 😂
I recall seeing an ABC story on Peter Andrews over a decade ago. It left a lasting (good) impression because it made sense.
Peter Andrews’ books, Beyond the Brink and Back From the Brink, are a great place to learn about his visionary work.
Hi, thanks for the names of his books. I always forget what they are called.
Thanks from Geoffrey
I have both of his books and have scanned them so I can give them to friends that are interested. The remediation works seem so practical! I would love to see you do a series of videos every year or so to see how the areas develop.
Hi, sorry it has taken me so long to reply.
His books are great books.
I have done an older video showing some of the other work we have been doing
Regenerating salt affected land
th-cam.com/video/vTwgSvjD9SI/w-d-xo.html
I will keep showing this as everything grows and the land hopefully becomes healthy again.
Thanks from Geoffrey
I think you just admitted online to illegally redistributing the books 😆
What are the names of the books?
@@mathiasfriman8927 Beyond the Brink and Back From the Brink
Nice one old Mate. I think Peter Andrew’s came from NSW. Did a lot of work around the Hunter Valley if my memory serves me correct 👍
His property in the Hunter was called Tarwyn Park.
Hi John, I am glad you enjoyed my video. Yes that is correct and at the time he got in a lot of trouble from the agg department for what he did.
Thanks from Geoffrey
@@unicornadrian1358 I believe it was in the Bylong Valley Between Sandy Hollow and Rylstone NSW
For a moment I thought you were going to criticise Peter Andrews, so I am glad you recommended his methods at the end. 😅
He did some great work and the weirs are working well.
Thanks from Geoffrey
sedges work really well to create the natural weir effect, they also help reduce pollutants and create habitat for critters, as well as helping stabilise banks etc
Doing well mate. Keep up the fantastic regeneration work 😊😊😊
❤ perfect sense. Am establishing this in one of nzs driest regions. Careful swale establishment and a couple of ponds to save what little comes ❤
We have a property local that has put Peter’s thoughts to very good use, and have well documented it over the last 20 years. Look up the Mulloon Institute.
Fantastic job on both those weirs. Looks like the downstream side of both of them could really use another leaky weir each to start filling up those eroded channels.
Hi, we are gradually building more weirs. Yes they do both need another one below them and then up stream as well. It’s a very long term project.
Thanks from Geoffrey
I tried the hay bales, the rabbits enjoyed that feed. So then used old carpet and it works a treat.
Attn: Carpet attracts mold & oall sorts growing on/in it.. the Water & Solis now contaminated as Carpet rots😮
@@CollectiveConsciousness1111 Yeah, but straw rots mighty quickly. The carpet I put in is still working well after five years, it collects the fines and makes for very clean water on the other side, although goats have nibbled it down to bank level.🙄
Looks to be a great idea, thanks for the demo
Hi, it seems to work well and is almost free to build I do need to put some smaller rocks in the big one to slow the flow a bit more.
Thanks from Geoffrey
I like that version. I will replicate yours very soon on my place.
Hi, it is a very easy and cheap way to build them. Good luck with your creek lines.
Thanks from Geoffrey
Excellent
make the bottom half of the dam impervious to leaks and then smaller aggregate on the next quarter and big rocks on top quarter also wing out the top of the dam so that water can't cut around it. Dam should be 6" to a foot lower than the top of the bank.
Hi, thanks, yes we are working on putting wings on the weirs to spread the water. The big weir was just built by dumping rocks with the front end loader and we realised that this is not the best way to do it. The more recent ones are built with a more graded agrigit to keep more water in the lower part.
Thanks from Geoffrey
❤six foot. Depending on soil structures and context.
Brilliant, another way is dig out a good deep depression however long with gradual slopes entry and exit. This will help with cattle entering to drink
Interesting!
Why has it taken so long for us to figure out an effective way to not only conserve water, but add ground moisture and replenish water aquifers at the same time.
The US and the UK are reintroducing beavers into degraded waterways and the results are spectacular.
In the UK, who hunted their beaver population into extinction 400 years ago, it's more about recreating wetlands that once covered the island and flood mitigation.
Hi Chris, I don’t think it’s that we didn’t know, it’s that we have forgotten about a lot of old technology and ideas that we Euston just use as a matter of course. We are now trying to reinvent the wheel.
I have herd about the reintroduction of the beavers. I am glad it is making a difference.
Thanks from Geoffrey
It is hard for people to understand something they get paid to not understand. I think Peter Andrews is not the most diplomatic of people, he's a brilliant visionary but not much of a diplomat, as I understand it. There is a nice documentary about his struggles here on youtube, titled "How Peter Andrews rejuvenates drought struck land" or something to that effect.
I have 40 ac in northern nevada, for anybody that wants to do a project like this i can tell you. Desert land is CHEAP!!! But one must be willing to put out hours and hours of real work, sweat equity is nice though. Once the land is restored its value is massivley increased. Its a real investment in these uncertain times.
Hi, that’s a great idea. The productivity of most land can be increased if you know how.
Thanks from Geoffrey
Make it pay. When environmentalism pays it will become as important in history as all the Ages, Stone, Bronze, Iron, Steam, Plastic, Ai.
That land is habitat as it is. It's not needing "restoration". It is needing people appreciating the stuff which already grows and lives there.
@@DavidOfWhitehills Disturbing habitats to make stuff look green for human eyes isn't really "environmentalism", it's "farming".
@@whatilearnttoday5295 its been destroyed and "parched" by humans. Killing Beaver and overgrazing, theres to many cedar where there are cedar and it should be grassland with water where its sage flats. Restoration is needed.
Chuck some gypsum in instead of hay bales. That soil is sodic and dispurses. That will also help more clay to aggregate around your weir
Cheers mate
Thanks
good job mate
Hi, thanks. They are doing a great home.
Thanks from Geoffrey
You mentioned salt marsh I think? Is the white stuff on the banks of the smaller creek salt?
Hi David, yes the smaller creek was a dry salt pan when we bought the property. It has improved a lot over the last few years. Yes the white stuff is salt that is still remaining.
th-cam.com/video/vTwgSvjD9SI/w-d-xo.htmlsi=wO40YTiNduDIXS9i this video has some photos of what it looked like before we planted anything.
Thanks from Geoffrey
Nice
Good on you mate
Hi, thanks, I am gla d you enjoyed it.
slowing the run off down works great
At 1,31 minutes in the video you pan the camera a little and show a crossing about 15 yards downstream from the weir. place another little leaky weir there as a crossing, only 2 or 3 rocks high and wide enough to drive over. P Andrews sometimes did things in pairs. They will protect each other and grow a lot of interesting grasses.
Hi, there actually is a small weir on the lower side of the crossing, you just can’t see it from this angle. It needs to be build up another few rocks to make it work better. Thanks from Geoffrey
I’ve been interested in Peter Andrew’s techniques ever since he first appeared on “Landline” all those years ago. Thanks for sharing your experiences. You might care to look up the Savory Institute in TH-cam as well. If I understand correctly, intensive farming methods with cattle or sheep to improve soil quality, grass growth and water retention through maintenance of topsoil. Worth a look and also developed by an Aussie I think?
Allan Savory has a lot of bunk in his contentions. Selection bias is applied heavily. Findings from specific habitat types are applied broadly in an inappropriate fanatical manner.
Good for us , good for animals.❤❤❤❤
Andrews also threw branches and planted water plants
thank you. a beauty.
slow water running into the creek area shallow contour with disc plow above tree line slow water shedding
deep rip as well
Hi, yes we do some ripping and contouring. We also try and seed along the contours where posable.
Thanks from Geoffrey
Look up book ...yeomans keyline farming australia. It's a whole of farm plan based on the keyline contour line .rather than concentrate water into a valley , the technique speads the water along the valley slopes . The book I have must have been written in the 50s or
60s....
Nice Work!
Looks like you deal with a lot of salinity their you guys have so it is a good idea for the saltbush that stuff is such a hardy shrub
Hi, we are lucky we only have a small amount of salt land, but yes the salt bush is great and gradually we are getting grasses and clover back on the land.
Thanks from Geoffrey
Nice trick to know
They work really well if you use smaller rocks.
Thanks from Geoffrey
Multiple leaky weirs will also help replenish any ground water basins beneath your land.
Hi my name is Casey. Hi fella the plan for improving long term creek improvement is seasonal little steps. As impressive as the weirs look the fact is a System needs to be built up from the ground. IE if Said plan is followed a underditch trench dug. Then infill materials follerd. Start from the ground.
Hi Casey, yes any regeneration is a long term project. We do a little bit more each year on our degraded land and are gradually making headway.
Thanks from Geoffrey
Mate to me those leaky weirs have been100% successful, if I wee you I would be looking at gradually widening those leaky weirs by at least 2-3mts and spreading your moisture retention area
You received the Video from you tube because they TRACK you and then bombard you with what they want you to watch same with google.
Originally the creeks flowed above the plain, not in gullies. According to accounts from early explorers. Then cattle came and damaged the natural weirs.
So, wouldn't it be better to put the leaky weir downstream of the eroded bank, so that the silt is deposited there to stabilise them?
My best guess is to slow it before it erodes the damaged section any more. I also see your point. Lots of flow factors, and soil types to consider.
need 12 t digger and tilt bucket batter banks back grass wont grow well on vertical bank
Hi, no the grass wont grow o the vertical bank, but gradually the water and silt are changing the shape of the bank for us.
Thanks from Geoffrey
how long ago were they built?
Hi Michael, they are about 3 years old. The small one filled up really quickly. The bigger one needs some smaller gravel put in it.
Thanks from Geoffrey
Would be a good idea to establish what's upstream and what's downstream first, and then explain what's going on. There's no depth perception in a video, so it's really hard to tell just by looking. But if you explain it a bit more right at the start, it will be a lot easier to grasp what's going on.
Hi James, thanks for your comment. I will try and give a better explanation next time i am talking about the leaky weirs.
Thanks from Geoffrey
Yes I’m thinking the reason why water moves quickly down the stream is because it has a set destination, and those people downstream are used to that water, so if that farmer is taking some, and other farmers are taking some, it can only mean downstream is getting less. I mean, maybe it just goes out into the ocean, I don’t know the destination of that little creek. But from that farmers perspective, I’m sure he’d want to do something like this - What a good idea he says to himself! but maybe for people downstream, probably not too good? But I really love videos like this. Someone thinks they have a good idea and they want to share it, and I love that. I also love that I can make comments about it! So thanks.
like it,,, I like the first bigger weir the best,,,although there is somethimg missing, Peter Andrews has a diversion drain at the flood level that will divert water to the floodplain in a flood event , sometimes going a few hundred meters.. Yours doesn't have that yet ?? Peter Andrews did not invent this nor did he start it. Other ancient cultures have done this for centuries, the yeminis did this, the arabs did this in oasis areas, beavers do this. There are others also. And, the big "And" whilst P Andrews had knee high clover on the flood plain in February due to his methods, remember P A Yeomans had knee high clover on the ridges , not just the flood plain. just sayin !
Hi, yes we plan to make a contour bank out along the flood plain, we just haven’t managed to do it yet. I am awake that he didn’t invent them, but it is the easiest place to direct people to go and get more information. Some of the African countries also have some interesting water catchment techniques. Yeomand did some really interesting things too. I need to go back and read his work again to use abit more if it. Thanks from Geoffrey
@@brookdalefarm7986 Yeomans v Andrews .- Andrews does creek restoration and floodplain restoration whereas Yeomans does upper catchment type restoration, Yeomans' work is basically above the floodplain, although there is nothing stopping one from keyline ploughing the floodplain, it works quite well. Just quickly, love the mechanic work you do,,, farm mechanics is real good do it yourself stuff.
Why do I have audio only in my Right earphone in the first minute?
Hi, I think I may have had a problem with my mic that day.
Thanks from Geoffrey
Just put back all the old tree trucks which have been removed to "clean it up".
That's a good weir
Hi James,
Thanks, they are easy to build like this.
Thanks from Geoffrey
Common sense. Plant more trees and vegetation nearby too.
Leaky wiers are the equivalent of beaver dams .
finished his book, in my opinion probably what strikes me about your weir is no plants he says that they were the main thing and apart from reids the remaining aussie plants are not up to it became they are all arid in nature suggests planting willows on the weir and creek line until the topsoil can recover. second thing is it doesn’t appear to be wide enough, the idea was that there was no flow at all even in winter as on flat land such as this the rivers were closer to lakes where they had had almost no flow or very slow flow and were wider than they were long almost. by making it much wider but shallow a lot more water is stored than in a narrow deep channel. anyway just my uneducated observations!
Hi, we are still working on slowing the water more. Yes we need some more plants there. We are using river salt bush in some places and this is working well. This creek has a lot of erosion in it already, so the first step is to slow the water and strop the sediment washing away. Once some of the channel has filled up a bit we will make the wall wider so the creak flows out onto the flood plain.
It’s a slow process, but it’s moving in the right direction.
Thanks from Geoffrey
The Willow thing is simply a bad idea. Allan Savory does a lot of damage with that technique. If the local plants can't survive in the habitat you're creating, then you're doing something very wrong.
@@whatilearnttoday5295 in the book he explains that Australia used to be an island forest and first aborigines with their burning techniques and then European arrival bringing mice rabbit killed off most of the plants leaving the arid plants behind, so plants like Willows are useful in providing the function for plants that no longer exist here
@@ynocoolnamesleft That's entirely gibberish. No, the outback was not a forest before burning. That's clearly nonsense.
Nothing in Australia benefits from Willow being planted.
@@whatilearnttoday5295 okay but according to his book it was and I tend to believe him a little more than you 😄
I hope you convinced yourself how beneficial these leaky weirs are, Because it definitely doesn't look like it.
Peter Andrews life was destroyed over the promotion of his methods that he refused to give up on. I watched the story years age
What so peter andrews is thousands of years old. This has been around forever . I do believe had a lot of trouble with the authorities & within his own family. A supporter of was Gerry Harvey , the owner of harvey norman. Some of his practices , a little bit different to say the least, resulting in a band of followers.😊
Isn’t this technique obvious? People needed to “ discover” leaky weirs. ?
It wasn't invented by anyone ...the beavers been doing it for millions of years....😂😅😊
Not in Australia they didn't.
The weirs occurred naturally, until cattle were introduced in Australia. According to accounts from early explorers.
@BOpal-cl6of there was no need for it before the introduction of hard hoofed animals that compacted the soil and concentrated the water run off.... talk
with the black fellas, the rivers ran clear with no silt in them..... I think you miss interpret my comment... I'm all for his innovative use of the concept.
Every landholder in Australia should be made to do this!
Impositions of inflexible templates by centralised planners, backed by force of violence, do not generally give benefits to any other than those central planners.
Leaky weirs... Who cares, farmers have killed all the creeks and rivers long ago and continue to amplify the damage. Because a farmer, making money is more important than the rivers streams and land that they farm.
It’s called common sense
