Environments - Quarantine Laws

The Plant Quarantine Act (1912) is a national law restricting importation of all kinds of plants.

It allows imported plants to be distributed only after a waiting period and careful inspection for pathogens (harmful diseases) and insect pests. It was passed as a direct consequence of chestnut blight.
