[APWG] Jewelweed TERMINOLOGY?

[Wayne Tyson]

JewelweedAll:

I don't mind the term "early-successional," and still find the concept useful after years of derision, but if a large group of ecologists don't like it and/or don't use it, what might be used in its place that would satisfy everybody without misleading others? 

WT

PS: Is it not to be expected that, after removal of one type of vegetation that other species might not colonize the "opening?" Is it not also to be expected that, as other, more slowly-developing species grow, that the "early successional" colonizing species might decline?

  We have found it early successional after removing non-native invasives near water such as porcelain berry.  But this is only temporaty. it quickly declines to normal as other natives come back in a year or two.

  Has anyone had any experience with jewelweed (Impatiens) native to the eastern U. S. becoming weedy in valley marsh habitats in the intermountain West? 

  I see that jewelweed Impatiens capensis (orange jewelweed) is listed as a King County  (WA) "Weed of Concern". 

  This species is shown as having a yellow flowered form, which is what we are seeing.
