Question

how can we conserve our vegetation answer in 120 words

Answer 1

Do not plant or import non native plants. Pull up and destroy non-native plants. Do not carry plants, firewood, leaves, nuts, cones etc. from one area to another. This can introduce pests and disease. Do not use herbicides, insecticides, or fertilizer if possible. They can all cause unintended negative effects. Do not clear out wooded areas, the rotting leaves are part of a nutrient cycle. The most important thing, of which all the above is related to, is to introduce nothing and take away nothing from natural areas. Let them do their own thing.
