There's a puddle in the low spot behind your yard that appears every March and vanishes by June.
It looks like a drainage problem. It looks like something the landscaper should fix. It has no inlet and no outlet. It fills with rain and snowmelt and sits there, shallow and brown, collecting leaves.
It is the most productive habitat per square foot on your property.
Vernal pools exist because they disappear. No permanent water means no fish. No fish means no predation on eggs. Every amphibian that breeds in your region evolved to find exactly this — a temporary, fishless body of water where eggs can develop without being eaten.
Spotted Salamanders have been walking to the same vernal pool for decades. Wood Frogs will only breed in water that dries up. Fairy shrimp — translucent crustaceans that look like they belong in the ocean — hatch from eggs that have been dormant in the dry soil since last spring, waiting for the water to return.
The entire cycle happens in 90 days. By summer the puddle is gone and there's no evidence it was ever there. But the salamanders it produced are in your garden now, eating slugs. The frogs are in your leaf litter. The fairy shrimp eggs are in the dry mud, waiting for next March.
If you fill it, grade it, or drain it, that cycle breaks. And it doesn't come back.
The puddle isn't broken drainage. It's an engine that runs once a year for 90 days and fuels everything around it.
