Map: Red Oak Seed Sources (IMAGE)
Caption
This map of red oak seed sources provides an example of a major threat to an important effort against climate change: major government and private funding is being invested in planting trees as a powerful tool to fight local and global warming. But new research in the journal Bioscience, from which this map is adapted, shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don’t grow close to enough trees—nor have the species diversity needed—to meet ambitious planting goals.
