AB  - This dataset consists of the relative frequencies of <i>Cirsium arvense</i> (Creeping thistle) of the Family Asteraceae recorded on Section 8 plots of the Broadbalk Wheat Experiment, 1991-2018. Section 8 has not received any herbicides in its history. 



<br />The collective weed fauna, and frequency of each species such as <i>C. arvense</i>, differ in response to fertiliser treatments which vary with each plot (see Related Documents below).
