Many UK apiaries sit on heathland or moorland — exactly the vegetation types most prone to fast-moving wildfire in dry spells. A dropped smoker ember, a badly extinguished hive tool fire, or an electrical fault in a honey house wax-melting area can all become the ignition point for a fire that spreads through dry heather and gorse far quicker than most beekeepers expect. This model runs a simplified cell-to-cell fire-spread simulation across a heathland grid, with an apiary and a honey house sited at the edge, so you can see how ignition source, wind and vegetation moisture interact with a cleared firebreak.
The UK's National Fire Chiefs Council recorded record wildfire seasons across heather moorland in recent hot, dry summers — several of which threatened outdoor apiaries. Beekeeping bodies now recommend a written fire plan for any apiary sited on open heath or moorland, including a cleared perimeter and a water/fire-beater cache at the site.
A cell-by-cell wildfire-spread model of a heathland apiary and honey house, showing how a single spark from a smoker or an electrical fault can turn into a fast-moving fire — and how wind, dry vegetation and a cleared firebreak change the outcome.
Each heather cell ignites its unburned neighbours with a probability driven by vegetation dryness and biased downwind by wind speed. A cleared firebreak strip removes fuel in a band ahead of the apiary, showing how width alone can stop or fail to stop a front.
Choose an ignition source (dropped smoker spark or honey house electrical fault), set wind speed, vegetation dryness and firebreak width, then press Ignite. Watch whether the fire reaches the hives or honey house before burning out.
UK fire and beekeeping guidance recommends a mown or bare-earth margin of at least 2–4m around apiaries sited on heath or moorland, plus keeping smoker fuel, wax and honey house electrics well clear of dry vegetation during fire-risk periods.
