  • poppies and bluets (cornflowers?), i remember reading, used to grow everywhere because they weren’t disturbing farmers till glyphosate entered the picture and started killing everthing but the crop

    C. cyanus is now endangered in its native habitat by agricultural intensification, particularly by over-use of herbicides.

    Centaurea cyanus is considered a noxious weed in arable crops, especially cereals and rapeseed. In winter wheat, one plant per m2 can cause a yield loss of up to 30 kg / ha. Centaurea cyanus produces around 800 seed per plant, which are either shed shortly before the harvest of cereals, or they are threshed together with the cereal grains, contributing to the further spread of the species by the harvesting machinery and contaminated seed. The occurrence of Centaurea cyanus strongly decreased during the last decades due to improved seed cleaning, more intensive nitrogen fertilization and herbicide use. However, Centaurea cyanus has become more common in cropland due to an increase in crop rotations dominated by winter cereals and rapeseed and the use of more selective herbicides with a low effectiveness against Centaurea cyanus. In addition, the emergence of resistance against the herbicide class of sulfonylureas has been reported recently. Due to its strong roots, Centaurea cyanus is difficult to control mechanically in spring.

    Does OSM have copyright easter eggs?
    Although some OSMers have deliberately added errors to the OSM data as well (see posting on legal-talk by User:80n), this is strictly discouraged and contrary to OSM policy. It’s also very unnecessary. Even if we seek to represent reality perfectly, that will never be the reality of map data. With OpenStreetMap there’s a very unique and distinct fingerprint evident in the data coverage and details included, and yes, in the errors made. For example in 2012 the OpenStreetMap foundation could issue a statement with absolute confidence that Apple had used our maps (without crediting us) based on very evident copying, and without the need for introduced errors.
