1 net additional tree per dwelling;

for non-residential development 1 tree per 100 square metres of additional gross internal area;

hedgerows, which must be planted as linear habitat, and where feasible enhance ecological connectivity.

Where the development includes or creates streets, these should be tree-lined, and should be designed to maximise climate resilience benefits, including urban cooling and stormwater management, using species appropriate for future climate conditions.

New tree and hedgerow planting should be supported by a management plan secured for a minimum of 30 years through appropriate mechanisms, as agreed with the council.

Where this level of tree and hedgerow planting is not achievable on site, a section 106 contribution towards off site planting schemes may be necessary subject to viability.

Planning policies should recognise the wider benefits from natural capital and ecosystem services including the economic and other benefits from trees and woodland. Planning policies and decisions should ensure that new streets are tree-lined.

In 2020, City of Trees committed to working towards planting three million trees (one for every person living in Greater Manchester) in the city region, within a generation (roughly 2045). However, unlike a canopy target, planting targets do not account for tree losses from development or disease. Therefore the strategy known as ‘All Our Trees - Greater Manchester’s Urban Forest Plan’ (the ‘Forest Plan’)36 sets out to improve the way in which we plant and manage our trees and direct us to where new tree planting will provide the most benefits for generations to come, using canopy cover as the main metric rather than number of trees planted. The Forest Plan encourages a move toward a natural capital approach when considering proposals for tree losses and replacements – moving beyond basic numeric replacement conditions.

In 2022, the UK committed to plant an additional 2% of land with trees to reach a 16.5% canopy cover from a baseline of 14.5% by 2050. To support this, The UK's Forest Research agency has published new national datasets on tree cover, which we can use in the future to monitor our progress. The Forest Plan sets out to increase on the UK ambition by reaching for an additional 2% canopy cover (on
