Cotoneaster (C. franchetti), Franchet's Cotoneaster. Single plant at north end of Lagoon 2 (red-orange berries in Sept). Non-native, garden escape, spread by birds eating the berries. (Note that many Cotoneaster, e.g. C. horizontalis, but NOT this one, cause problems to native plants by spreading and are illegal to plant in wild (i.e. added to Sched 9 of Wildlife & Countryside Act in 2010).)
Crack Willow – the hedge across Lagoon 1 shows Crack Willow (yellowy branches, green leaves, on left) and White Willow (green branches, darker green and longer leaves with white backs, on right)
