Greetings to all:
The comment on the woodpecker's ecological role
(ivory) has been in my mind for a while, particularly
because I work in forests that are actively been used
by people that are after the wood, that is in
developing countries, the price of gas does impact
directly on the amount of wood burning, and Mèxico has
been on an energy cruch at the personal level (high
oil prices don't necessarly reflect on one's pocket).
So, something that has always impressed me of
mexican forests is that they are very easy to walk
around, no fallen dead trees no obstructing big
branches that I remermer form my younger years at the
US.
I wonder if anyone has done some deadwood "load"
effects on other biotic niches or guilds, most of us
would almost acertain that a large load should be
essential for a "healthy" forest ecosystem, is there
any avidence supporting that?? What would be a good
indicator?? number of beetles per sq. meter?
Cheers and happy holidays
