Like, you're not taking that down.
Our trees elicit this emotional response in people.
We have about 5400 cultivated trees that we're maintaining on campus.
The goal today we have a locust tree.
It's not making enough energy.
So the so the branches start to die back and we get dead wood.
And that dead material i is adjacent to a bike path and a and popular area wher people walk and sit and stuff.
I been working in like trucking and warehousing and came to Boulder.
You know, saw an ad for groundskeepers and thought, I want to work outside.
I want to work with plants.
And, came on board here as a seasonal groundskeeper.
I became a certified arborist through courses and workshop and and labor time in the field.
In order to get our ropes up into the tree.
We use what's called a throw line and ideally just want to get it as high up in the tree as possible.
So it could be take 2 or 3 throws, or some days it's like one of us is like I threw it 25 times.
I'm like all at one of them.
Try.
We want to make sure people come and visit campus.
Everything looks prim proper.
It's a place that they want to come.
They want to send their kid to, and they want to come back and visit.
But once you get up in the tree, it's just as simple as cutting branches in a wa that you can easily hold on to.
So nothing gets away from you.
Before I started working in tree care and I was just like, oh, trees are nice.
And you know, I like them and they do fall color.
But like once you start learning about them and adding specific species and like you see enough trees, it shifts your perspective.
We're working on them in our own, you know, human timelines, but they can be hundreds of years old.
And so you're, you know, taking care of something and affecting something that's going to be there long after you're gone and positively benefit, you know, future generations.
