Species:
Convolvulus arvensis
Common Name:
field bindweed
Systems Affected (standardized):
cropland
Regions(s) present (updated by AB):
ALL
Impacts:
grows rapidly and will compete with native vegetation for nutrients, moisture, space and light. Plants will climb neighbouring plants and as a result alter habitats and decrease the biodiversity of an area. The foliage of C. arvensis contains alkaloids that can cause intestinal problems in horses grazing on heavily infested pastures.
Source? likely to be reintroduced:
C. arvensis is generally present all over the world, but it is not a major weed in most of these areas. C. arvensis produced a large number of seed which can remain viable for up to 20 years. These seeds are dispersed locally by water but they may also accidentally be introduced with the movement of seedstocks in commerce, and by clinging to mud on farm vehicles. As such, it is likely that the distribution of this species is likely to increase.
Info Blurb:
Grows rapidly and will compete with native vegetation for nutrients, moisture, space and light. Foliage contains alkaloids that can cause problems for grazing animals. Produces a large quantity of seeds which can remain viable for up to 20 years.
