Associated data to article: To moo or to mow - disentangling the effects of management on Gladiolus imbricatus in coastal meadows

The data were collected in the years 2021 to 2023 and in 2025 in permanent plots across sites under different management regimes. Management regimes can be divided into two categories: long-term management (mowing, mulching, grazing) and short-term adjustments of mowing and grazing (mowing date and grazing intensity).

After initially marking the 10 m x 10 m permanent plots in 2021, nine points were designated within each plot at distances of 1, 5, and 9 m from each corner. These nine points were treated as corners and data were collected in 50 cm x 50 cm quadrats. In each quadrat, the endangered perennial herb Gladiolus imbricatus was counted: 1-leaved individuals were classified as juvenile, 2-leaved individuals as vegetative, and any shoot with flowers or visibly grazed flowers as generative. All vascular plant species found in each quadrat were listed. The total number of data points included in the study was 198 per year (22 plots x 9 quadrats).
