With respect to the various comments I am getting, specifically from Chip<br>
Taylor, is anyone doing studies to determine whether roadside refugia<br>
serve as sources or sinks for pollinator or beneficial insect populations,<br>
given the inevitable mortality? It would be helpful to know whether
the<br>
mortality is more than compensated by fecundity. It would also be
helpful<br>
to associate that with road capacity/size and traffic use and patterns.<br>
<br>
Also, we need to know which ROW management practices help or hurt species.<br>
For example, many roadways here in Utah are mowed in late June or early<br>
July. Is that ok? Or does not increase mortality, cause loss
of<br>
reproductive output, make habitat unsuitable?<br>
<br>
On another note, if we improve these areas for pollinators, does that<br>
result in an increase in mortality of birds that might use the habitat
or<br>
might feed on the insects?<br>
<br>
Roads are really lethal. We need to know whether, and under what<br>
conditions, it is beneficial or detrimental to manage them for wildlife.<br>
