The good news? America has more trees than it did 100 years ago. Aggressive efforts to replace decimated old-growth forests paid off. The bad news? The new forests have a far less diverse selection of tree species than the originals. The fresh batches are often crowded into smaller spaces, so wildfires are more massive and devastating. Since so many of the forests are young, they host a reduced diversity of plant and animal life. The increased quantity is wonderful; the lower quality not so much. The lesson? In upcoming decisions, favor established quality over novel quantity.
