Would someone with access say how short they were mowing?

  > Lawns were mowed from May through September in 2013 and 2014, using a Toro 19″ self-mulching push mower, (mowing height set at 6.35 cm). Grass clippings remained on the lawn. We assigned each yard to a mowing frequency regime: mowed every seven days (oneweek; n = 8 yards), 12–14 days (two-weeks; n = 7 yards), or 18–21 days (three-weeks; n = 8 yards) to represent the range of typical mowing behaviors (one to two weeks) to a more extreme frequency (three weeks; Robbins, 2007). Seven yards participated in both years of the study and thus these repeat yards were assigned a different mowing regime for the second year of the study. To ensure households adhered to the experimental restrictions (e.g., frequency and height of mowing), we provided a free lawn mowing service and mowed all participating lawns for the duration of the study > Summarized bee abundance and richness in relation to lawn mowing treatments were as follows: weekly mowing = 1425 bees representing 72 species, mowed every two weeks = 1903 bees representing 60 species, and mowed every three weeks = 1259 bees representing 62 species (Fig. 2, Appendix A1). Our rarefaction analysis reflected these overall abundance and richness values, showing lower bee richness in the two-week treatment
