<DIV><FONT face="Book Antiqua" size=4>While we don't usually think of
predator-prey relationships with plants, there can be situations where alien
plant removal procedures are detrimental to ecosystem health. And the lesson
here of understanding interspecies connections and making predictions that are
testable as theory, then test plots, then useful procedures, beats the "find
'em, whack 'em, and forget 'em" approach that is far too widely used (sometimes
with good results,* but too often with negative or neutral results). While
consideration of the whole ecosystem context may take more time, it can minimize
error, expense, and wasted or counterproductive effort. </FONT></DIV>

<DIV><FONT face="Book Antiqua" size=4>*Ecosystems are resilient--that is,
"forgiving." But correlations are not always reflective of causation, and a
shift in context can mean success in one case, failure in another. </FONT></DIV>

-- Efforts to remove an invasive species from a sub-Antarctic <BR>> island
that has been named a World Heritage site accidentally triggered an <BR>>
environmental catastrophe, a study to be published on Tuesday says.<BR>>
<BR>> The eradication programme on Macquarie Island, lying halfway between
