Dear People involved with trees.

Why do people spend a fortune on tree treatments they do not understand, yet
will not spend a couple of dollars on literature to help them understand?

Subject: [dead_wood] Information on impacts of fuelwood harvesting


>
> Dear colleagues
>
> In Tasmania's native wet eucalypt production forests, there are
> currently proposals to increase the harvest volumes ('reduce the
> wastage') by harvesting a proportion of what used to be called 'residue'
> but which ecologists call coarse woody debris. The aim is to use this
> in a wood-fired power station which would feed into the electricity
> grid.
>
> Our concerns about this practice will be obvious to members of this
> discussion group, but justifying our concerns to those with a more
> 'utilitarian' vision of forests is proving difficult. What I would like
> to know is, are you aware of any research that has looked at this issue
> from an ecological perspective in other parts of the world? And if so,
> how has it been resolved, or hasn't it?
>
> Our forests have huge natural volumes of CWD, which is why harvesting
> some of it is so appealing to the 'utilitarians'. But my feeling is
> that the biodiversity associated with CWD here will have evolved
> alongside these large volumes, so we can't say that it's OK to take most
> of it because there will still be plenty left. Because of the naturally
> high volumes of CWD, many of our species are likely to have very low
> powers of dispersal, which is why we have proposed prescriptions that
> retain CWD on every forestry coupe. The 'utilitarians' would rather
> rely on the formal and informal reserve system to ensure the survival of
> CWD dependent biodiversity across our forestry landscape: it would make
> forestry (and fuelwood harvesting) much simpler.
>
> If you have any views on this that can help us frame ideas for maximum
> effect, please let me know.

> Thanks
