Tulip Tree Succession

Added: 2026-05-18

[00:00:00]I'm standing right now in a thicket of tulip trees or tulip poplars, Liriodendron tulipifera. These trees that are surrounding me have grown up in a gap in the canopy. Likely a larger tree has fallen, letting a lot of light into the forest floor, and this tree is racing up right now to fill that gap.

[00:00:17]Tulip tree loves to do this, and it's kind of unusual because although being a pioneer or earlier successional species, unlike most pioneers, tulip tree will actually grow very old and will take a climax role in a mature forest. Most pioneer like paper birch or quaking aspen are fast growing but short-lived, and so they fill a gap that occurs from disturbance, but then they die out when climax species or slower growing, more shade tolerant species grow up past them. Tulip tree can be considered a pioneer species for the fact that it's shade intolerant, fast growing, and often invades recently disturbed areas like gaps in a forest or very commonly in the southeast, old fields or abandoned agricultural land. However, it will grow up rapidly like any pioneer, but then it will create a long-lasting presence in the forest where it will live hundreds of years, and it will act as though it's a climax species. So, when I come to an area like this and I see a whole bunch of small diameter young sapling tulip trees, I can be sure they all colonized this area when the light was appropriate when suddenly a gap was opened.
