9 November 1999 Green Group Warns on GM Tree Development BRUSSELS (Reuters) - An international environmental group said on Tuesday a growing number of genetically modified (GM) trees were being cultivated without reliable safeguards and called for a global moratorium on their commercial release. The World Wide Fund for Nature said in a study that commercial GM tree production could begin in the next two years, probably in Chile, China and Indonesia, despite what it said were inadequate regulations and insufficient research into the environmental impact of trees modified by biotechnology. ``WWF is calling on governments worldwide to declare a global moratorium on the commercial release of GM trees until enough research has been conducted and proper safeguards have been put in place,'' Jean-Paul Jeanrenaud, head of WWF's Forests for Life Program, said in a statement. ``It is far too early to judge whether biotechnology can make a safe and effective contribution to the forest sector.'' WWF said there could be a risk of genetic pollution, the development of ``superweeds'' and unwanted effects on non-target species from trees engineered to be resistant to pests and agricultural chemicals. The group said that in the last 11 years, there had been 116 confirmed GM tree trials in 17 countries using 24 different tree species, of which three quarters were timber-producing. Most tests are in North America. France leads the way in Europe. The WWF report -- ``GM technology in the forest sector'' -- coincides with growing public concern, particularly in Europe, about the safety of GM foods. Lawmakers and the biotechnology industry are seeking ways to make the technology more acceptable. WWF accused life science companies of pushing the technology in regions where regulations governing trials were less strict than in the developed world. Trees can be genetically engineered to increase growth rates, modify wood structure, alter reproductive cycles, improve tolerance to herbicides and perhaps even store more of the gases that are responsible for climate change, the report said.
