Because of their greater competitiveness, weed species readily invade bare areas of ground which have been denuded of vegetation.
Drought, fire and even floods can create these conditions as they devastate existing ground cover, thereby removing all competition for light, nutrients, moisture and space.
This devastation allows quick weed establishment when more favourable conditions arrive.
Weeds already on the property may quickly spread to new areas, and weed densities increase.
