Cultural control is a process were land is managed to insure good condition with sustained use. If the land (soil, plants, ecosystem) has been damaged and is "unhealthy" it is easier for invasive species to move in. Damage can occur by natural disaster (flood, fire), recreation (camping, off road vehicles), over-grazing, or farming. This control method is most often practiced on agriculture-based lands (cropland, pasture, and range), but can also be used in gardens, parks, and our native wildlands.
Cultural control combines parts of the other control methods, but focuses on improving the "health" of the native plants. If the native plants are healthy, it is harder for a weed to become established. If a weed does become established, the native plants are better able to compete and suppress the weed's spread.
of use that an area of land receives must be monitored to prevent damage.
For example, both recreation and grazing take place on much of our western
grasslands and forests. Each of these land uses can cause serious damage
if not controlled. The impacts and damage caused to the land depend on:
Croplands are also managed using a number of tools that suppress weed infestations. Smother crops are used to form dense vegetation stands to compete with weeds during the off-season. Competitive crops that are quick to germinate, have a fast growth rate, and are tall in stature can also be used to suppress weeds. Crop rotation is another effective means of fighting against annual and short lived perennials. The type of plant, the time of planting, and seed-bed preparation are all an essential part of cultural weed control.
