[PCA] Fw: [Pollinator] Roads and pollinators - again

[Lewis_Gorman at fws.gov]

It's hard to believe that managing Interstate and limited access highways, 
clover leaves, etc. by merely not mowing them (except for safety 
requirements) would not be of overall advantage to all wildlife.  Is a 
study really required to determine an overall benefit?  Increased 
biodiversity alone should justify supporting a reduced mowing policy on 
highway lands.
There must be millions of acres being mowed at great cost, petroleum 
energy use, and associated air pollution that would be significantly 
reduced by halting mowing, except as minimally required by federal highway 
safety specifications.

[Pollinator] Roads and pollinators - again









With respect to the various comments I am getting, specifically from Chip
Taylor, is anyone doing studies to determine whether roadside refugia
serve as  sources or sinks for pollinator or beneficial insect 
populations,
given the inevitable mortality?  It would be helpful to know whether the
mortality is more than compensated by fecundity.  It would also be helpful
to associate that with road capacity/size and traffic use and patterns.

Also, we need to know which ROW management practices help or hurt species.
For example, many roadways here in Utah are mowed in late June or early
July.  Is that ok?  Or does not increase mortality, cause loss of
reproductive output, make habitat unsuitable?

On another note, if we improve these areas for pollinators, does that
result in an increase in mortality of birds that might use the habitat or
might feed on the insects?

Roads are really lethal.  We need to know whether, and under what
conditions, it is beneficial or detrimental to manage them for wildlife.
