What the literature leaves open

  • The lack of plot-level records combining taxon-specific cover with geographic coordinates in the Baltic region. The uneven availability of plot-level records across the region.

    Georeferenced Plot-Level Data on Urban Grassland Vegetation in Jelgava, Latvia · 2026 · DOI

  • Future studies should explore how different management strategies, such as cutting frequency and plant diversity optimization, can affect the ecological benefits of wildflower strips. However, the effectiveness of wildflower strips may be influenced by cultivation practices, habitat quality, and landscape scale, which warrants further research to optimize their design and management.
