Reference data for field practitioners and land managers.
Why Pollard, Not Top?
Pollarding creates a defined pollard head that regrows from established bolling tissue, reducing the long-term risk of structural failure. Simple topping without establishing a pollard head produces responses that are harder to manage in subsequent cycles and increases decay risk in Betula pendula, which has moderate wound-compartmentalisation capacity.
Polish Regulatory Context
Under the Ustawa o ochronie przyrody (Nature Conservation Act), removing or substantially pruning trees over specified girth thresholds on private or agricultural land requires municipal notification or permit in certain circumstances. Local authority (gmina) requirements vary; checking with the relevant urzÄ…d gminy before major works is advisable.
Birch and Fungal Risk
Betula pendula is susceptible to bracket fungi including Piptoporus betulinus (birch polypore), which colonises stressed or damaged trees. Avoiding large pruning wounds when the tree is under drought or waterlogging stress reduces infection risk. Autumn and early spring are the recommended low-risk pruning windows for mature birch.
