Grass can go almost unnoticed for most of the year, but by summer聽it's speedy growth demands our attention. Suddenly, the state of the wicket, or Wimbledon's courts, matter. And who can resist a stroll through a swaying meadow, alive with wildlife and flowers.聽

This is increasingly difficult in Wales though, where聽grass meadows聽have declined rapidly. The same is true of seagrass,聽once found in abundance off the Welsh coast.

He visits Bodnant Gardens聽in Conwy where attempts are being made to restore the park's meadows to their former glory. Adam also talks to Dr Richard Unsworth, of Swansea University, whose research into seagrass聽could help put more fish like cod in our waters.

And in Aberystwyth, the聽IBERS聽team that once put the green into the Wimbledon Courts - and the spring into the Milenium Stadium, talk to Adam about their pioneering work with high-sugar grasses.
