Andrew/Jenny- Yes, you've both got it...silviculture itself is benign...the goals of the agency or entity can warp that (depending on one's stance...;>)
The silviculture I practiced, I'm proud of...I made a difference in the time that I worked in the field. I know that Joe and Mike are comfortable with their silvicultural efforts. The same within aquaculture. It all depends on your stance...I'm an Alaskan, and I'm particular now, now that I've eaten fresh caught wild Alaskan salmon over several seasons. Not all aquaculture salmon are created equal, some of the 'cultural' practices are more ecologically sound than others, and like silviculture, I'm a fan of best management practices...and I think that the use of "best" means it is not static, but can ALWAYS be improved. Another word that probably crosses these disciplines is "sustainable", I'll bet! -Don > Date: Tue, 8 Dec 2009 16:40:32 -0500 > From: [email protected] > To: [email protected] > Subject: Re: [ENTS] Re: More French Tree ID please > > An analogy that comes to mind is aquaculture.
