The National Tree Improvement Strategy (NTIS) aims to promote UK trees through selection and breeding of a wide range of tree species capable of thriving in UK conditions. This will include broadleaves and conifers, native and exotic. NTIS aims to promote economic value, genetic diversity and species resilience. This will produce trees with good vigour and timber quality, showing resistance to known pests and diseases and able to withstand the seasonal and longer-term climatic variations. NTIS will also ensure that selected material is available to all interested parties.
