There are some very thick hedges on the estate. The Blackthorn hedge between the lower and upper meadow is about 5m from one side to the other. It is, in effect, a strip of woodland allowing wildlife to move around the garden unobtrusively. Blackthorn is a source of nectar for the bees, a food plant for moths -the lackey, magpie, common emerald, swallow-tailed moth and yellow-tailed moth. It is also used by the black and brown hairstreak butterflies, but the latter are rarities not seen here at Broadacre. Birds nest in the safety of Blackthorn's dense, spiny branches and deer lie low for the day deep in its thickets. We have Roe deer and Muntjac.
