Bee swarm in Bletchley? Help is a minute away.

Bletchley is the historic railway town at the southern end of Milton Keynes, famous as the wartime home of the Government Code and Cypher School at Bletchley Park. The mansion grounds and ornamental lake at Bletchley Park carry mature limes, sycamore and bramble scrub; the Fenny Stratford canal basin on the Grand Union Canal gives riverside willow and alder; and the Victorian and Edwardian terraces of the older Bletchley town centre sit among established gardens that carry a reliable late-spring flow.

Oilseed rape is grown extensively on the agricultural plain around Castlethorpe, Hanslope and the fields north of Wolverton, opening the main flow in late April; the Great Ouse floodplain meadows carry white clover and riverside wildflowers through June and July. The linear parks of the new city — Ouzel Valley Park, Loughton Valley, Linford Wood and Campbell Park — carry lime trees, hawthorn and bramble through a long urban season. Lime trees were planted extensively on the boulevards and parkway margins of the new city in the 1970s and 1980s and now carry a strong June urban flow across the grid squares; hawthorn and blackthorn are thick on the original field hedgerows surviving within the linear parks. Woburn Sands and Aspley Heath, straddling the Bedfordshire border, carry heather and gorse on acidic sandy soils — an unusual local forage note for a lowland Midlands city. Bramble is prolific on the Redway scrub and former railway embankments; ivy on the stone walls of the old villages closes the year.
