Cirsium arvense, Houthem


This former field, one of the field of Lepidoptarium in Houthem, has been cultivated for more than one hundred and fifty years. Due to the nitrogen and other nutrients present in the soil, this field has undergone a special development. Plowing the land
Preparation for manual sowing has awakened the field thistle seeds that have been waiting for years. These displaced the sown native wild flowers, which meant that this intervention had to take place in the field.
