Professor Paul Lucas has described Edmund Burke's theory of prescription as his "idea about the way in which an adverse possession of property and authority may be legitimated by virtue of use and enjoyment during a long passage of time." The description is accurate so far as it goes. Burke certainly maintained that if one had held uncontested possession as the owner of a piece of property for a sufficiently long period of time, no earlier title to the property, however valid, could be revived and made to prevail against the occupant's title. Through the passage of time the occupant had acquired a title by prescription, and this in Burke's eyes was "the soundest, the most general, and the most recognized title … a title, which … is rooted in its principle, in the law of nature itself, and is indeed the original ground of all known property." Burke also said: "Prescription is the most solid of all titles, not only to property, but, which is to secure that property, to Government."

Sustainably managed non-native trees deliver economic and societal benefits with limited risk of spread to adjoining areas. However, some plantations have launched invasions that cause substantial damage to biodiversity and ecosystem services, while others pose substantial threats of causing such impacts. The challenge is to maximise the benefits of non-native trees, while minimising negative impacts and preserving future benefits and options. A workshop was held in 2019 to develop global guidelines for the sustainable use of non-native trees, using the Council of Europe – Bern Convention Code of Conduct on Invasive Alien Trees as a starting point. The global guidelines consist of eight recommendations: 1) Use native trees, or non-invasive non-native trees, in preference to invasive non-native trees; 2) Be aware of and comply with international, national, and regional regulations concerning non-native trees; 3) Be aware of the risk of invasion and consider global change trends; 4) Design and adopt tailored practices for plantation site selection and silvicultural management; 5) Promote and implement early detection and rapid response programmes; 6) Design and adopt tailored practices for invasive non-native tree control, habitat restoration, and for dealing with highly modified ecosystems; 7) Engage with stakeholders on the risks posed by invasive non-native trees, the impacts caused, and the options for management; and 8) Develop and support global networks, collaborative research, and information sharing on native and non-native trees. The global guidelines are a first step towards building global consensus on the precautions that should be taken when introducing and planting non-native trees. They are voluntary and are intended to complement statutory requirements under international and national legislation. The application of the global guidelines and the achievement of their goals will help to conserve forest biodiversity, ensure sustainable forestry, and contribute to the achievement of several ...
