If asked to define a forest, readers might say, "It has a lot of trees." But many places have a lot of trees. So, what makes a forest a forest? Readers discover that a forest is unlike any other biome on Earth. And a temperate forest is even more specific.

In addition, readers learn by examining how forces usually considered destructive work to help forests survive. 32pp.
