Soil Warming Research Sites

Caption

This shows research sites at the Harvard Forest Long-Term Ecological Research site in Petersham, Mass., where Frey and Melillo have been warming two sites with underground cables. The photo was taken during a January thaw on a 50-degree day; the heated plots, which had been snow-covered, melted before the unheated ones.
