One Man's Farm Became a 187,000-Acre National Park, and It's Still Growing

Entomologist Doug Tallamy wanted to know what would happen if he stopped fighting his Pennsylvania farm and started working with it. He removed the invasive plants, seeded natives, and then paid attention. The result: luna moths returned, and he has since cataloged more than 1,380 moth species on that single property. That’s not a nature documentary. That’s one man, one farm, and a whole lot of patience.

That experiment became Homegrown National Park, a movement that now covers more than 187,000 acres with 52,000 registered participants. Tallamy’s pitch is simple arithmetic: if just 10 to 20 percent of landowners planted native species, the combined habitat would be larger than 10 Yellowstones. No credentials needed. No wilderness required. No government action necessary. Just a decision about what grows outside your door.

What makes this story land is how ordinary the beginning was. Weed-pulling and seed-spreading, not expensive intervention. The movement grew one yard, one fence line, one ditch at a time, and that means there’s room in it for anybody with a patch of ground. A native planting doesn’t care whether you own 40 acres or four feet of curb.

So what’s growing in your yard right now? Have you ever planted something native and watched what showed up? We’d love to hear your story.
