Sammanfattning: Loss of biodiversity is a global concern and one of the affected habitats are meadows, where we have a large species richness among fungi and vascular plants who interact in ways that are poorly researched. Many of these meadow species are severely affected by reduced meadow areas which have been converted into farmland, lost their rich flora and mycota because of added fertilizers or have been left unmanaged. The purpose of this study was to investigate if there is any connection between species richness in plants and fungi on meadows, if the meadow age affects species richness, and if environmental variables such as pH, shadowing, moss and soil type has an effect on species richness. During the summer of 2021 plants were counted and in the fall the fungi was counted. Statistical analysis was performed on two different datasets, one with all species counted, one with plant species that have their main habitat on meadows, and fungi commonly known as waxcaps. The result showed a significant connection in species richness between plants and fungi when all species were tested and when a selection of meadow living species was tested. The effect of time showed that the youngest meadow contained the least number of species. Shadowing for plants had a significant negative effect when all species were counted, and all other tests of GLM-models showed significant effects on plants by fungi and vice versa. The results show that there is an interaction between plants and fungi, although we today have a poor knowledge about the actual functionality of these interactions. Other studies have tested low-cost methods to establish meadows in cities and ski slopes, where it is possible to create new suitable habitats for species that have meadows as their main habitat. One of the meadows in this study shows that overgrown meadows can be restored with great results.
