I am looking to understand how different native trees with different functional traits compete against Japanese knotweed.
The traits I want to consider include:
1. Species with different light requirement( e.g light demanders versus shade tolerants)
2. Species with different nutrient requirements (e.g species that do well in nutrient rich soils versus those that perform well in poor soils)
3. Species with different growth rates (e.g fast growing versus slow growing)
4.Species with different root forms (e.g deep rooting versus shallow rooting)
5.Species with difference in seasonal adaptation (e.g evergreens versus deciduous trees)
What tree species, native to Northeast America, should I select to compare for each functional trait I am considering?
You need to visit affected areas and compare biodiversity with pristine sites
@Andrew Paul. Thanks for your answer. The site I am dealing with is heavily infested with knotweed and almost all the natives have been out competed. I am looking to conduct a greenhouse experiment to assess which native trees (with specific functional traits) compete well against knotweed on our site. Hopefully the findings will inform our tree selection and planting decisions in the future.
Thank you Rodrigo. I will be doing a green house experiment similar to what you recommend.
Sure, I will be glad to share the progress and results. I just started harvesting my knotweed rhizome buds for propagation. Thanks for the luck.
