Default High plant diversity component in suppressing invasives?

Prairie manager sets test plots to confirm data showing high plant diversity combats invasives. Read what he has to say about his data and that from others confirming diversity's importance.

Quote:
How important is plant diversity? Most ecologists think it’s a critical component of resilient ecosystems. Last week I collected some data that lends support to that view. In some experimental prairie plantings we’ve established in our Platte River Prairies, plant diversity appears to be suppressing the invasion of poison hemlock (Conium maculatum).

However, one of the most intriguing aspects of plant diversity is its potential to help suppress invasive species. If we continue to find that more diverse plantings help repel species such as bull thistle and poison hemlock, that will have important implications for both agricultural producers and wildlife/prairie managers.

Very cool. Nice to know there is research like this out there.

I've only read the excerpts not the article, but it makes sense to me that if there are natives filling every niche, there would be less chance for seeds of invasives to get a foothold.

I read the article and think it sounds promising. I'd love to see other studies with other invasives...and one in a woodland setting.

Thanks for posting it, Gloria
