Water germander is a very rare plant that has been declining in its range and population. However at Kingfishers Bridge this decline has been reversed and numbers are rising rapidly. It likes the area between winter and summer water levels, being in water over winter and in damp conditions in summer. Although it produces viable seed it appears to spread through bits of the plant breaking off, floating to the shallow water edges of pools where it takes root. If the water is clear it is happy spending the winter 30cm below the surface.

Common Reed will grow in water up to a metre deep. It grows as a fringe to parts of the mere and ditches as well as dominating the reed bed. Species such as Bittern require wet reedbeds for feeding and nesting. The reed was established using seed which was pre-treated to aid germination, then carefully sown into prepared areas planned for the reed bed. This technique worked well, although equally effective was to broadcast the seed on the surface of the water and allow it to float to the muddy margins where it also germinated quite happily. Other species using the reeds are reed and Sedge Warblers, Reed Buntings and Harvest Mice.

On the limestone grassland Venus's-looking-glass is an annual which likes disturbed calcareous soils. Decreasing nationally it is regularly found at Kingfishers Bridge amongst the sparse vegetation on the limestone.

Additional species are continually being recorded at Kingfishers Bridge, having found their own way to the site.

Southern Marsh Orchids have colonised a few areas of damp alkaline soil and Saw Sedge is now established on the edge of the reedbed. The total plant list is over 350 species.
