<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I couldn’t agree more, Mr. Tyson, on
the importance of using proper (and well-defined) terminology in any
sub-discipline of ecology. After all, ecology itself has often been considered
the “soft” doctrine of the biological sciences, and any clarification
and standardization of terminology is welcome and necessary to furthering effective
research, communication, and “conservation” (and increasing the
relative standing of ecology as a discipline). When considering ecology’s
standing as a science, I am often reminded of the pre-eminent physicist, Sir
Ernest Rutherford’s dismissive comment of turn of the (last)-century
botany (and I paraphrase), “Botany is fine; it is about as difficult a
science as stamp-collecting.” [ouch!]<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'> I too, turn to
the definition of invasive species posted below and often point out that a
species which escapes at a constricted scale and doesn’t persist in the
environment (displays low population fitness) is not (to me) “invasive”
(and I am reluctant to use term even though it is part of my job title!). However,
at what temporal and spatial scales do we arbitrarily choose to demarcate as a
threshold for “invasive” or not? Defining populations as “r”
or “K” were once valuable in the budding discipline of population
biology and ecology; and while still taught in Universities, these have similar
limitations; just as the once useful definitions “apex” or “healthy”
(or even trying to fit population dynamics to a Lotka-Voltera” model) do.
These limitations create problems such as your (common) distinction between
“ruderal” and “healthy” (does this mean that all “ruderal”
systems are “unhealthy”?). As a result, these terms and
approaches fall from favor and the supporting concepts evolve to better
describe the wide range of dynamics we observe and record. New terms will
inevitably arise.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>As to <i><span style='font-style:italic'>Impatiens
capensis</span></i>: I’m not sure if your last two sentences, “It
appears that some believe there is no distinction. I would appreciate any
correction, definitions, or suggestions that will bring discipline to
communication about these subjects.” refers to the present discussion
about this species. If it does, I would suggest reading the excellent Zika
papers below. If it doesn’t, and speaks to the larger issue of communication
among peers, then perhaps the lack of distinction stems from colloquial
discussions such as this one. Either way, your point is a very important one
that bears consideration and we would all be wise to retain it.<o:p></o:p></span></font></p>

<br>
I don't usually make comment to this group....I generally browse this list to
see what new issues are popping up. As a
biologist/ecologist/naturalist/land manager for 31 years in the Chicago area
with the Forest Preserve District of Cook County, I have seen this plant come
and go. Deer do browse it heavily and tend to prefer it over most other
plants. It does well in disturbed areas where the soil is rich, moist and
semi shaded. I have always viewed it as sensitive plant that is easily
displaced by weeds and never thought of it as a problem plant in the Chicago
area. The fact that it is spreading prolifically in other areas where it
typically does not occur could be a symptom of a bigger problem. I would
expect it to disappear when those problems are discovered and solved. <br>

situation where the native species is potentially being out-competed by both
the introduced species and by their hybrids. Zika has published another paper

Has anyone had any experience with jewelweed (Impatiens) native to the eastern U.
S. becoming weedy in valley marsh habitats in the intermountain West? <br>
<br>
I see that jewelweed <i><span style='font-style:italic'>Impatiens capensis</span></i>
(orange jewelweed) is listed as a King County (WA) “Weed of Concern”.
<br>
<br>
This species is shown as having a yellow flowered form, which is what we are
seeing.<br>
