Portugal 50-Metre Land Clearing Law (2026): Deadlines, Rules & Fines

A comprehensive practical guide to Portugal's fuel management regulations (Gestão de Combustível): May 31st deadlines, contractor costs, protected tree exceptions, and coercive municipal enforcement.

Statutory Clearing Rules: Distance, Tree Spacing and Deadlines

Portugal's land clearing law requires all owners of rustic land containing buildings to establish a 50-metre defensible buffer by May 31st each year. Clearing does not mean stripping topsoil: it requires thinning brush so that vegetation remains under 20cm, pruning tree branches up to 50% of the tree height (minimum 4m from ground), and keeping tree crowns separated by at least 4 metres for pine and eucalyptus. Native protected trees such as cork oaks (sobreiros) and holm oaks (azinheiras) cannot be felled without prior written authorisation from ICNF, even if they sit within the 50m radius.

Contractor Rates, Neighbour Boundaries and Coercive Execution

Standard professional forestry contractor rates for fuel management range from €800 to €2,500 per hectare depending on tractor accessibility and incline. When a house is located within 50 metres of a property boundary, the neighbouring landowner is legally obligated to clear the remaining perimeter on their side. If neighbours fail to comply or cannot be contacted, owners can file a formal report with the municipal Câmara or GNR-SEPNA, initiating coercive municipal execution (execução coerciva) where the town hall clears the land and taxes the absentee owner.
