Amwell Nature Reserve is a complex of lakes, reedbeds, grassland, scrub and woodland in the Lee Valley, located south of Ware. The lakes were created by sand and gravel extraction between1973 and 1990 by St Albans Sand and Gravel, which then became RMC Aggregates, which in turn was taken over by Cemex. Cemex continued ownership until December 2006 when it was bought by Herts and Middx Wildlife Trust, which will ensure that its status as one of the best birding sites in Hertfordshire will be safeguarded for the future.

King?s Meads, between Hertford and Ware, are the largest remaining grazed riverside flood meadows in Hertfordshire, covering 96 hectares or 237 acres. The rivers and ditches, which criss-cross the site, traditionally flooded the flat land although, due to falling water levels, this now happens less often than in the past. However, ditch restoration and the maintenance of a system of sluices is gradually restoring the water levels to the meadows during the winter months.
