The same species.
In Oregon, a wildlife ecologist is studying how to collapse vole populations before they destroy grass seed fields.
In the Mojave, another scientist is doing everything possible to grow a vole population that almost disappeared forever.
Both are right. Both are necessary.
And that contradiction told me something important.
The problem was never voles.
The problem is always context. Location. Balance.
In my garden, voles had no natural predators. No population pressure. Ideal tunneling conditions. An unlimited food supply I had unwittingly planted for them.
They weren't invading. They were just doing what voles do in a place that had become perfect for them.
Poison wouldn't fix that.
Poison would kill the voles currently in my garden. And within weeks, new voles would find the same tunnels, the same food, the same perfect conditions.
The infrastructure would remain. And the cycle would start again.
I needed something different. Something that changed the environment itself, not just the animals inside it.
