The light, transparent beech leaves give a frail green light in the wood. The bluebells have withered and are forming fruit. Spiked rampion, yellow pimpernel, ramsons, sweetscented bedstraw en false lily of the valley are some spring flowers that are flowering. On the banks of the ponds, yellow flag is flowering. The first galls can be found on some trees, as on the upper side of the leaf of the lime: the red horn-shaped galls, ‘nail galls’ of the mite Eriophyes tiliae. Small red knots of the mite Aceria cephalonea on the upper side of the leaves of the sycamore; and on the underside of the leaves the spherical galls of the gallwasp Pediaspis aceris.
