Yes, I think it's possible, and a lot of forest scientists are very concerned that the mountain pine beetle, for example, which is the existing insect problem we have in B.C., because it feeds on lodgepole pine, there's a significant possibility that this species could learn to adapt because there are such high population numbers. There's so much genetic change and generational change in that insect, it could end up moving into the jackpine forests and then move across to boreal forests in very closely related tree species. That's just one insect pest. There are many, many other insects, many other fungi, bacteria, that could change the relationship with changing weather conditions, changing water regimes, changing temperatures.
\nEnvironment Canada and many university scientists have done a lot of looking at how the temperature regime, as it shifts, will change the ability of particular tree species to grow in different areas. I'm sure some of you have seen that scenario, whereby suddenly you can grow black cherry very effectively in the James Bay lowlands by 2100. Black cherry is not going to get there, it has no way of getting there, but there's going to be a very different growing regime for the trees that would normally grow there, if it's suddenly that much warmer.
\nThe interaction of all these factors is not terribly well known. I don't know a single research scientist who looks at this stuff who would say in this particular area--like north of Thunder Bay or north of North Bay--in this particular plot, this is what you can expect to happen. No one knows. It's change, and that's the only constant people look forward to.
", "fr": "Oui, c'est possible. Bon nombre d'experts en sciences foresti\u00e8res s'inqui\u00e8tent beaucoup que le dendroctone du pin ponderosa, par exemple, qui infeste le pin ponderosa de la Colombie-Britannique, puisse s'adapter, en raison de ces fortes populations. Les modifications g\u00e9n\u00e9tiques et g\u00e9n\u00e9rationnelles sont si nombreuses chez cet insecte qu'il pourrait finir par s'attaquer \u00e0 des for\u00eats de pin gris, puis infester des esp\u00e8ces \u00e9troitement apparent\u00e9es dans les for\u00eats bor\u00e9ales. Et il ne s'agit l\u00e0 que d'un seul insecte ravageur. Il y a bien d'autres insectes, champignons, bact\u00e9ries et parasites qui pourraient \u00e9voluer compte tenu des changements climatiques, des nouveaux r\u00e9gimes hydriques et des temp\u00e9ratures accrues.
\nEnvironnement Canada et de nombreux universitaires ont examin\u00e9 comment les fluctuations de temp\u00e9ratures modifieront la capacit\u00e9 de certaines essences d'arbres \u00e0 cro\u00eetre dans diff\u00e9rentes r\u00e9gions. Je suis s\u00fbr que certains d'entre vous avez entendu parler du sc\u00e9nario voulant qu'on pourrait cultiver le cerisier tardif dans les basses terres de la baie James d'ici 2100. Je ne crois pas que le cerisier tardif migrera vers cette r\u00e9gion, ce ne serait pas possible, mais un r\u00e9chauffement consid\u00e9rablement pourrait entra\u00eener des r\u00e9gimes forestiers bien diff\u00e9rents de la normale.
\nOn ne conna\u00eet pas tr\u00e8s bien l'interaction de tous ces facteurs. Je ne connais aucun chercheur dans ce domaine qui puise dire ce \u00e0 quoi on peut s'attendre dans des r\u00e9gions particuli\u00e8res \u2014 par exemple au nord de Thunder Bay ou de North Bay. Personne n'en sait rien. Le changement est la seule constante que l'on puisse pr\u00e9voir.
