Case-by-case
The owner or holder of a land area must apply for a landscape work permit in order to carry out earth works, tree-felling or similar action altering the landscape in areas covered by a local detailed plan. A landscape work permit is also required in areas covered by a local master plan, if the plan so requires.

No landscape work permit is required to fell individual trees for the purpose of caring for plots. Neither is a landscape work permit required for actions that are related to an issued building permit.
