From the field

Three years ago the plain outside Tipi was grassland. Every dry season the fires came through, and every season the seedlings that tried to take hold were burned back to the ground. From the air it looked like savanna. It had not always been.
We went back this spring to walk the same ground. Where there was grass there is now young Caribbean pine, knee high, shoulder high, and in the oldest protected areas already above your head. Driving into it is the strangest part. There is a track through what is now a forest, and none of it was planted in rows.
The seed was already in the ground. Mature pines that survived the fires kept dropping it, year after year, onto land that burned before anything could grow. The change was not planting. It was protection: firebreaks cut before the dry season, brigades patrolling and turning out when a fire starts, controlled burning that removes the fuel a wildfire would need, and communities who decided the land was worth defending.
Where natural regeneration is too thin, planting is added to help it along. Most of what we walked through came back on its own.
This is one area, and the work is a few years old. The fire season returns every year, and areas outside the protected ones still burn. What the young forest near Tipi shows is narrower than a promise, and more useful than one: when the fires stop for long enough, the forest that was always trying to grow finally can.
That is the clearest answer we have to the question people ask most, which is whether this actually works.
