Hi Jean. After posting a very long message below, I realized that I still hadn't really addressed the issues you brought up. I'll attempt to do that now, and I'll try to be a bit less long-winded.
I am aware that loss of old-growth forests and use of Corucia as bushmeat are also threats to wild populations. However, I don't see this as a reason to purchase WC animals. I’d like to break my reasoning down into 2 categories; logging and consumption as bushmeat.
Logging will continue whether we import Corucia or not. There is a chance that by creating a market for non-timber forest products (like flora and fauna that are forest obligates) we can create an incentive to sustainably manage the resources. However, for a system like that to work you need 2 things that the Solomons don’t currently have; a stable government with the authority and the ability to regulate resource use, and buy-in from the local people. Buy-in can be created if there is financially more to gain from the exploitation of the non-timber products than from timber. An adequate political situation is much harder to come by. The Solomon’s, as I’m sure you know, are years (if not decades) away from this.
As for bushmeat consumption I can’t say precisely what the situation is in S.I., but if it’s anything like the bushmeat situation in Africa or Latin America then the ban or lack thereof will make very little difference in terms of local consumption. The majority of folks who eat bushmeat do so because there are simply no other protein sources available, usually due to financial restraints. If/when trade is reopened it will make little difference, as the people who do the actual field collection do not make enough money from this work to put them in an economic class where they could afford commercially produced meat. Studies in Africa and Latin America have shown that consumption of bushmeat does not change based on the availability of the animals for export.
In addition to all of that, I'll reiterate a point I made in my other post, which is that Corucia haven't declined to the point yet that we should give up on the wild populations. Anything we do at this point to remove more of them from the wild contributes to other factors of decline and pushes the species closer to the edge.
Jean (and anyone else too), if you find the topic of sustainable use of wildlife as incredibly fascinating as I do, you may be interested in the book “Hunting for Sustainability in Tropical Forests” edited by Robinson and Bennett or “Integrating People and Wildlife for a Sustainable Future” edited by Ables and Hamre. The first one especially is very well written, is relatively up-to-date and has quite a few herp-related articles, which is rare.
Well, I think I was a bit more concise this time. Fire away!
