But can you just talk a little bit about the importance of biodiversity and what that looks like in practice for you guys in your ranch?
11:00
Yes, Lauren.
11:00
And when we talk about biodiversity at the ranch, we talk about the biodiversity of the microherd to begin with.
11:07
And that's one of the reasons why we have, like, the, you know, the fungi and bacteria and all these organisms that live in the soil, and that's one of the reasons why we have multiple species of grazers.
11:18
We have, uh, one herd of l- of cattle, saddle horses, mares, and donkeys and sheep.
11:25
Well, sheep is a separate herd, but the other, all, all of the rest are on one herd.
11:31
And that actually provides different manure, different way of eating, different way of fertilizing and different microbiology because at the end of the day, there's is an exchange of the microbiology that is, you know, on the manure, that is on the urine, that is on the saliva and so on.
14:51
So talk a lo- talk us through your guys' approach to the actual cattle that you have on your ranch and how you go through your culling process every year.
16:12
What happens first? Is it, is it weeds and then that becomes something else? Like, describe the process of once you can get some air into the soil and get the water in there, then how does the ranch progress into being these beautiful, um, tall grasses?
16:26
Yeah.
16:27
Um, let's keep in mind that we start in most of the places in my ranch with bare ground.
16:33
So when you...
16:35
Even if there's really not much to it for...
16:38
I'm gonna be using cows, but it could be pretty much horses or donkeys or sheep or goats, but when you use the cow, the cow has multiple tools to help you.
16:48
Even if, if you're just passing by, you know, like herding or driving, it has the hoof action.
20:21
Is that something that every rancher should be striving for? Is, is that kind of the golden number or what? Tell me a little bit about that.
