The Grassland Biome - Biomes #5
Вставка
- Опубліковано 2 сер 2024
- Grass. If there is one plant that has come to dominate our world, it’s this. Occupying every biome on earth except the icesheets, grasses have colonised every patch of soil, from tropical to temperate forests, savannah to steppe, scrubland to desert. Humans have taken these grasses and shaped them over generations into crops that feed the world today. Their homelands are the seas of grass we call Meadow, Prairie, Pampas, Veldt and Steppe - the world’s Grasslands.

Prairie is almost exclusively used to refer to the grasslands of North America, and is a word borrowed from the early French settlers to this region, meaning simply “meadow” in that language. Steppe refers mostly to the grasslands of Eurasia, and is taken directly from the Russian word for this biome. Pampas is the most common word for the extensive grasslands of mid-southern South America and is from the Quechua word for plain. Veldt, the Afrikaans word for field, is a loose term to describe the open upland country of eastern South Africa that is sometimes grassland but might also be scrub.
Grasslands can be found in these countries: Canada, USA, Peru, Bolivia, Argentina, Brazil, Uruguay, South Africa, New Zealand, Turkey, Iran, Ukraine, Russia, Kazakhstan, Mongolia and China.
The domestication of various species of the grass family into cereal crops is regarded as one of the key developments of human civilisation. Wheat, corn, rice, barley, oats, millet, sugar and many more crops that directly, or through fodder for livestock, feed us, are all grasses. And so this humble family of plants that colonised the world and later went onto feed ours can be thought of in many ways as the most important in our world.

Hello everyone! I hope you enjoyed this presentation of the world's grasslands! Please let me know if you have ever seen natural prairie or steppe, and what your experience of it was like!
Anyone here for school work
Yes it was nice
yes
yeah im here for project
The most underrated biome as people think of grass not much more than just standard ground.
Excellent, as always! Loved the the little etymology bit as well.
Absolutely loved this intro. Have not seen a prairie although I live in North America. Wish there was a multipart series to look at the different biomes of the grasslands outlined in the video by continent. Thanks for your work!
Thanks very much!
If you go to the prairies in Canada or the USA you’ll be disappointed cause it’s all farms. There’s like no native wild grasslands. I’ve never seen em anyways and I’ve driven through the prairies in both countries.
Thanks and your efforts are really commendable.
Ha, perfect timing! I just watched the other biomes videos last night!
Oh.. was waiting for treat. . another visual treat and info. Ah! this is so sooothing!
Wonderful job! How much to learn about this biome, it is very interesting to hear how cereals, which are grasses, are the nutritional support of a large part of the world. You always exceed my expectations !!! I loved it! 👌👌👌
@@Geodiode There are many things to identify this channel, and one of them is the great quality of your work. All of them are made with such quality that people really get surprised after viewing them; and the quality is not only in the selected images that you choose, is also in the very well prepared graphics and also in the text, that being educational has poetic and artistic touches! You are a master! And I think most people agree with me that when they discover the channel they feel like they found a jewel! My Congratulations for your work!! (once again).
The production quality is superb
Great informative session on grasslands across the earth
Many thanks!
Amazing, great job 👍
Wow this video is really helpful and self explinatory. !!!!!
Thank you so much for sharing your videos. I am using it to teach for online learning during 'lockdown'.
Beautiful!
Another educational and enlightening video. Lots of information and very concise as well.
Thanks!
Wonderful!
Argentinian Pampas: 90% farmlands 10% natural
Argentinian South Prairies: 90% natural 10% farmlands
Excellent explanation
I'm Argentinian, and here, the Pampas are a huge part of our national identity.
Great to hear from you! Thanks!
Beautiful
👍🏻wow👍🏻nice explained 👍🏻
This was in my science class that my class watched. So helpful! Took notes
Very well explained sir. Love from india.
So nice of you
I love watching your videos

You're welcome!
Fantastic!
Yay new video
IS THAT PAPER PIG
great video 🎥
Thank you 🙌
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide.[1] There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands.[1] They cover 31-69% of the Earth's land area.[2][3]
🥰thank you so much
You’re welcome 😊
Awesome
Interesting 🤔👍
so nice wow
My Love Biom
Marvelous ❤❤❤❤
Thanks!
Good overview, though as I lived several years before college in steppe (or shortgrass "prairie") outside Denver then prairie in central Oklahoma, those are quite different in moisture (semi-arid vs. sub-humid) and even temperature (microthermal winter, warm-dry summer vs. mesothermal winter, hot-humid summer). Koppen seemed to miss this. They beg for a similar division as the deserts on the maps or videos.
Thanks, well, I say this quite a lot in response to demands for more subtlety or complexity in classification systems: Any classification system, to be simple enough for students and lay-people to understand, is going to make broad assumptions. I chose Koppen for climate and LONSO8 for biomes, as they were simple enough for this purpose. Real systems are just so complex that a classification system will never capture every aspect. But such a system that can teach others something, is better than a complex one that cannot.
Really music is so nc
nice vid
Thanks!
and best for Learning
really interesting 👍👍
Very nice video , in permaculture often the focus is forested gardening... I often wonder how to utilize grasslands though
@@Geodiode For sure, I was just trying to think of foods outside of the cereals. Grasslands seem to be more suited to grazing, but I'm sure you could farm on them with agroforestry. I just am not sure if trying to alter that climate immensely by having a forest is ok or a bad idea. Probably wouldn't hurt anything
@@Geodiode Yeah, well if you have the land space you would on grade create a swale to harvest water and build a fungal dominant soil there. At first you may have to plant around them to get a rhizomal barrier, but eventually the grass would get shaded out by the canopy if you planted a forest instead of just orchard. It wouldn't require continuous care as long as there was enough water and no initial grazing pressure. I can't think of a reason it wouldn't work. I'd incorporate grasslands in between swales with native grass mixture as a way to building root structure and building the carbon in the soil so more and more water gets held every year and working on contour to soak in the rains. After 7 years you get your water table built up because that is about half the time of a 15 year water cycle.
Grazing through holistic management (developed by Allan Savory) can utilize the grasslands as nature intended and even regenerate the health of the soil and support more animals
@@mckaychapple1737 Love Allan Savory, but my point is that's great that the soil is getting healthier and support more animals, but where do we grow our food that we humans eat? I know wildlife is critical to the ecosystem, but just thinking about uses for grasslands as humans... I can see why in history people have unfortunately had to resort to eating the animals instead of healthier plant foods in those regions. I bet someone out there has figured out the grasslands though and a way to thrive there. It seems like most grasslands are grasslands because there isn't enough rain or soil moisture to support otherwise. I could be off, but they as nice as they are from a habitat point of view given the choice seem far behind a forested or grassy woodland area. Mostly curious about groups of people or researchers that have found a way to thrive in the grassland without nutrient dense whole food plant based sources of nourishment for the people dwelling
I LOVE NATURE!!!!
choice video! :)
Differently abled student Maryam, 👍 likes this video.❤from Pakistan 🇵🇰
My favorite biome
Thanks for the extremely interesting video(and series). I have been wondering one thing: Why grasslands exist? Why grassland instead of forest transforming straight to shrubland when the amount of rain reduces?
@@Geodiode
Thanks. I need to check that out. If we look at the chart at 3:24 we can see that pure steppe is an anomaly. In warmer or cooler climates pure steppe does not exist which is very interesting. So, there must be something in the climate that creates conditions too dry for trees, but too humid(?) to scrubs and left grass to be total winner.
In my humble view, I see biome as a causality of climate. It is the climate that defines the victor in competition of dominant type of species, when nature is left alone untouched.
@@kampakala1544 it's about soil conditions and then geographic location in relation with the climate historic evolution.
@@m.debaser4
If it is about soil, why there are so large unified areas? Soil defines if an area is covered by spruce or pine here in north. And results in very un-unified forests.
@@kampakala1544 One word: Herbivores
This is a good vidio
Ande this vidoi help me alot guys thanks
Question - why does the tropical savannah biome feature sparse trees and shrubs (e.g. Acacia) while the temperate grassland is largely treeless, even in areas with more moisture/longer grasses?
It's a great question, and sadly, I have not been able to find out the answer to this. Note that there are some temperate mixed grass/tree areas, most notably in the mid-west USA (formerly, now all converted to farmland), and also in Iberia. Biomes are complex!
The term "Prairies" is used mainly in Canada. In the USA, the grasslands of the West are generally refered to as the "Great Plains".
Useful to know, thanks!
Not true, the Great Plains are the geomorphology of much of the area occupied by prairies, a plant community type. The use of tallgrass, mid grass and shortgrass prairie terms is common amongst ecologists, ranchers & recreationists.
I live in Canada and I drive across the prairies fairly frequently cause I live in B.C. But I’m from Ontario. Never seen the natural grasslands just farms upon farms upon farms.
It has always puzzled me that humid subtropical climates on South America have grasslands while on every other continent they are a mix of broadleaf and conifer forests.
What are the grasslands that appear in Mexico, are they part of the great plains or are they another region?
We wish wecouuld be there in those grasslands, don't we?
It is a pity that the pampas are not well preserved, the only places that remain unaffected are very small protected areas and some less fertile parts of them, Argentina did not really do a good job at that. Those that are virgin are the southern Patagonia grassland that is almost completely unaffected.
Apart from remote regions in the Central Asian Steppe, you'll find that most natural grasslands are more or less gone, for the reason mentioned in the video - they just make excellent farmland.
I came as fast as a tornado
@@Geodiode 😂😂
Just awesome, watching this complete series!
Glad you enjoy it!
I grew up and lived most of my adult life on the short-grass plains of Colorado, so I'm very familiar with at least one type of grassland biome and its associated climate. I now live in North Carolina and I love how green it is, but I miss the grass, the sky and the dry air of the high plains.
Woohoo Geodiode video
I love that calm voice
Love from 🇮🇳
like the biome minecraft game😉👌
❤❤
Very good presentation. Can you share source texts.
Thanks! Unfortunately I don't keep a record of my research, however, in the case of Biomes, Encyclopedia Britannica is generally excellent.
Are the vast plains of Mongolia, Kazakhstan, and other Central Asian countries suitable for crops? I heard that, since they are supposedly not, such is the reason why this region is relatively low populated. However, if crops are a type of grass too, then that shouldn't be a problem, right?
This is an excellent question! If you look at the North American Prairies of Canada and the USA, you find that almost every square mile has been cultivated. So why not the equivalent in Central Asia? The climate is more or less the same, and the soils shouldn't be that different. I suspect the issue is depopulation from historically political instability (think numerous marauding bands of horsemen, Genghis Khan, etc.).
@@Geodiode That's plausible, yeah. Thanks for taking the time to answer, I'm loving your videos too!
@@Geodiode In Canada, the growing season is so short and the climate so variable, that yields vary greatly from year to year. It makes farming rather risky. Also the Prairies are quite far from most markets. Fortunately government crop insurance, railways and other institutions and infrastructure make farming possible. It could be that in the Central Asian Steppe, the variability of the climate and shortness of the growing season is a bit more severe than in the Canadian Prairies, and the lack of infrastructure and the distance from markets, as well as political instability all combine to make agriculture unfeasible, at least for now.
I didn't know that wheat 🌾 and rice are grass species 🤭🤭🤭🤭 wow.
Information begins at 1:49.
I live near the pampas in southern Brazil
Thanks for stopping by!
are marshes covered in salt tolerant grasses grasslands too?
Watch my new Wetlands video for a deeper perspective on this. I mention salt marshes specifically. ua-cam.com/video/4bRgUShrC1w/v-deo.html
bamboos are grasses too, are bamboo forests or swamps a type of grassland?
An excellent question! The answer to which.... I dodged, because I couldn't decide myself. I think it ultimately comes down to semantics. One type uses lignin (trees), the other does not. But both are perennial species that maintain their growth year-on-year. If pressed, I would lean to referring to it as forest in character, even though biologically its really grassland.
👍👍
Yes,it looks beautiful, because no man is there.
I would argue a Savannah is still a grassland. Its basically the tropical version of a steppe
But you don't get trees in the Steppe, so I'm afraid they're not analogous in this regard.
@@Geodiode that's only because we have no mammoths anymore to disperse seeds into the steppe land. Look at the biodiversity of today's African Savannah and the Pleistocenes Siberian Mammoth steppe, its practically identical.
Eexcellent overview. Important revision would be to refer to the grasses as a Family of Plants, Poaceae, not a class. Additionallly, why are the Sahel and savannahs of central & Eastern Africa left out? It is incorrect to say the veld is the only large grassland of the continent of Africa.
Thanks. Yes it is Poaceaea. The Savannahs are covered in their own episode earlier on in the series.
I heard about a mysterious island look it up and let us know.
Can you please explain layering as well?
@@Geodiode oh! Well, In my book it's written that the grass in grasslands consists of three layers; Tall(Andropogon, Panicum), mid high(Stipa,Sporobolus, Oryzopsis) and short(Poa,Bromus). They form grasslands.
Actually I am a visual learner so I wanted to see how it works.
Btw sorry for my bad English.
Yessssh!!! 😭😭🥳🥳🥳😍😍
@@Geodiode oh yes! It totally is. I had been looking for videos on biomes from an exam and I stumbled across your channel. Which is btw an absolute lifesaver. ❣️😭 God bless.
@@Geodiode Hahaha that's accurate. Your content is absolutely brilliant. And it's helped someone like me who's geographically challenged 🤣 understand the subject. So hats off to you for that. 🤠😇
@@Geodiode Thank you so much. Most certainly I shall binge watch the other content on the channel post exams 😝. Have a great day 😇💜
🎉❤😊
why is Australia not considered to have grasslands?
it has shurblands instead
it is simply left out, Australia does have grasslands
0:21
So most dinosaur species never saw grass?
@@Geodiode lol imagine the first resurrected dinosaurs confused by the endless sea of grass in Isla Nublar
WOTT, smart that u pointed that out, thats a crazy revelation
*Mongolian throat singing intensifies*
Its on the pacific ocean.
ms bhama its rishav
I have to watch this for clas
same bro,,,
Grazing can save grasslands. Check out The Ted Channel on it
I watched that video some time ago. It was a real eye-opener.
Minecraft, but with ultra RTX on.
I thought grass evolved in the Eocene, not in the Cretaceous…..
was thought to be end of Cretaceous but newer phytolith discoveries reveal grasses in the late Cretaceous
The distribution map is kinda wrong because The largest Ecological biome in iraq is deforested Steppes especially in Western,North central,Eastern and Northern Iraq
Same goes for Syria,Jordan,Palestine,Lebanon and even northern Saudi Arabia
If you watch the first in this series, I talk about how there is a lack of consensus on what constitutes what Biome where!
@@Geodiode Sorry for judging you and yes you are actually right
GRASS
DO THE ROAR DADDY
