Month end and trees are reluctant to come into leaf, Ash still asleep, Oak just stirring, some Beech slowly greening over, Horse Chestnut in leaf. Only a few Butterfly seen during April chiefly Small tortoisesell. Still a few Daffs in flower, still some Celandine in flower (both blooms having been observed since December!). Bluebell carpets now impressive.
