What happens underground in Hill Country Karst Country?
This Sycamore, growing straight out of the karst limestone, gives a window into something that's usually completely unseen.
Notice the roots down below, making their way through the stone.
Grasses are absolutely a critical part of Central Texas, especially in bottomlands, but they can't pierce the stone like this. Grasses also can't take root when there's no soil.
So without trees, much of the Hill Country -- with our thin soils on top of rock -- would be barren of life. And without these roots finding the tiny cracks in the rock and opening them up, water couldn't make its way in.
No springs. No Frio River.
Or, at best, the Frio would be a seasonal dry-bed river that flash flooded every time it rained...
It takes native trees like Sycamores, Oaks, Cedars, and more, that make up the 'Oak-Juniper Woodlands' -- which historically made up most of the Hill Country -- to build the conditions for our hills to hold water and slowly release it. Conditions that feed our springs, that then feed our beloved rivers.
Protecting upriver forests is critical to our watershed. This includes the misunderstood, but keystone species for our region -- the Cedar (Ashe Juniper) tree.
And as we saw with the recent flooding, forested areas like ours can handle 5+ inches of rain, without significant runoff.
Widespread clearing, hoping grass comes in, and thinking that that will be good for your springs, is wishful thinking. You just need to slow down and think critically about it yourself. As we say in Texas, that dog don't hunt.
Let's change the narrative on what good upriver Hill Country land stewardship is, and treat our upland forests with the respect and appreciation they deserve!
