Brassica procumbens in Corsica (FR)
Brassica procumbens (Brassicaceae) is an annual species native to North Africa where it inhabits forest clearings, pastures, stony slopes on low mountains. In Corsica (FR), it is currently found on the edges of several roads and occasionally in fields and gardens. Generally, individuals are grouped in dense stands, with cover ranging from 50 to 100 %. Currently, B. procumbens appears to be spread through earth-moving machinery, and vehicles carrying materials for construction can act to spread seed. B. procumbens is now more widespread in Corsica than was previously known. This suggests that it is a species in full expansion along roadsides and in some fields bordering them. Therefore, in Corsica, B. procumbens should be considered as an invasive alien plant species.
