In fall, the local woods become a color-coded forest, making it easy to tell at a glance what species are growing where. Trying to take at least some advantage of this, I headed out in a car to survey where Asian photinia has invaded our nature preserves. The combination of its yellowish orange color and customary growth form aid in identification from the road.
Here's a new invasion getting going up on Mt. Lucas.
Once Photinia has lost its leaves, the honeysuckles are still green, revealing just how extensive is their invasion of the woods. That they hold their leaves long after native woody plants have dropped theirs suggests that the exotic honeysuckles evolved in a climate with a longer growing season.
