In addition to these new plantations, there are other divisive issues surrounding the eucalyptus today. ), Why Do Citrus Leaves Curl? Although there is little empirical information on the fire behaviour in Eucalyptus plantations under the weather conditions found in the southern Coastal Plain, our modelling effort focusing on fire behaviour at the stand level suggests that little may differ from current conditions, given the flammable nature of the native pine species, the authors concluded. (These people, Farmer says, were not reading blue gums lousy reviews in old farm reports. Blue gums cant reproduce on their own just anywhere in California; Yost says they need year-round moisture.
