Treebeard's Stumper
25 Apr 97

The untended fields around school are beginning to turn brown. What's striking is that these wild plants are almost all introduced species. They were brought here, intentionally or not, from somewhere else, and they took over, driving out the native flowers and grasses as they spread. Indignation is possible, but there's also a stumper here. The invaders didn't evolve in response to our unique natural resources like our native plants. So shouldn't the natives have the edge in any competition for living space? How can introduced species actually dominate the landscape?
