What are the best ways to control the spread of invasive plants so they do not become weeds?
Deb
There is no way to control an invasive plant once it is established. The plant should be killed and seed should be collected and destroyed. It is best to kill invasive plants before they set seed. Some of the worlds worst invasive plants are trees like the Camphor laurel. If there is a risk that the dead tree could fall on a house or something else then a professional arborist should be hired. So obviously it is best to kill these trees before they become dangerously large. And much easier to kill them when they are very young. If they are not dangerous drill holes with an electric drill about 1cm deep 2cm's apart and as you do that poor glyphosate concentrate into the holes. do not spill the glyphosate. a proper applicator bottle should always be used when applying herbicides for the safety of the environment and the yourself, you don't want to get the stuff all over you. Also avoid buying invasive plants from a nursery, that's right your local nursery probably sells invasive weeds. further reading - why do people insist on growing weeds. conclusion for this question is- kill as many as possible never encourage anybody to ever grow these plants. Let people know that growing invasive plants is environmental vandalism and let everyone know how nasty your local exotic nursery is because, not knowing is naivity, knowing but not caring is ingnorance, but actively encouraging growing these plants is nothing short of contempt. - why do people insist on growing weeds? and enjoy life because it is to short not to. =]

What is the best way to reduce threats from invasive species?
The best thing you could do is eradicate them as early as possible before they spread. For example 3 seeds of a foreign plant are brought to your country and dropped in the park down the road from your house. They grow and become small trees. You recognise them as a foreign trees or at least trees that aren't locally provenant, so you I'D. them correctly, and it turns out that they are nasty invasive species. You could do 2 things, one, let them set seed and proliferate throughout your community destroying your bushland. or, you could kill the 3 plants and save your local bushland with minimal physical effort or use of local resources. Same with animals. And the same on a larger scale. for example these plants have dropped their seed and spread all around the park. You could do nothing and let them keep spreading into other parks or you could start a plan of management and get in there and try to kill as many as you can and stop it from seeding and proliferating. The greater the number of different invasive plants or animals the more complex the removal process becomes and professional advise must be sought. Sometimes amateurs remove large amounts of for example Lantana camara but underneath the lantana is the seed of many herbacious invasive weeds which grow and seed faster than the people can remove them. The seeds of the herbacious weeds then become terribly invasive in the surrounding land or properties. In which case killing small amounts of Lantana at a time may have been a better option. Lantana can also provide habitat for small birds in areas that all their natural habitat has been removed. THINK OF THE ECOSYSTEM AS ONE WHOLE. =]
