The Effect of Timing of Grassland Management on Plant Reproduction

Table 2

Mean relative fruit production of 28 species occurring in five or more plots per the two grazing regimes: continuous stocking and late grazing, in the grassland Harpsund, see text for details. Differences between grazing regimes are tested using the Mann-Whitney 𝑈-test. 𝑁-values show the number of plots in which the species were present.
