Letter: Letters: Cranes and rafts

Published 9 November 1991

From FRANCIS HALLE

I have carefully read ‘A crane’s eye view of tropical forests’ (21 September).
Obviously, this crane technique is a very good one, and a lot of interesting
results are to be expected.

Being myself in charge of the so-called ‘canopy raft’ that you mention
in your article (and which we deliver by hot-air balloon, by the way, not
helicopter), I would like to make a few comments.

In my opinion, you should avoid saying that one technique is better
than another one: whether mountaineering rope, crane or raft, we need every
one of them, for they are good complements of each other. Rainforests are
being depleted so quickly there is no time left for polemics We should collaborate
by exchanging ideas, equipment, expertise and scientists.
