QUESTION NO. 18

QUESTION: Councillor J. Sinnott

To ask the Chief Executive what types of trees are planted in the public realm and in residential estates and how are the types of trees chosen for locations.

REPLY:

SDCC's recently updated ‘Living with Trees’ policy outlines a selection of 46 different species of trees suitable for planting within the public realm. Of these, 33 are designated for open spaces while the remaining 13 are intended specifically for street tree planting. These lists serve as guidance to the type of species considered appropriate for street planting. It is not an exhaustive list, and other trees may also be considered suitable for planting.

The choice of street trees is determined by several factors, including mature size, water requirements, crown shape, root development and ongoing management needs. Trees used in council-led planting programmes are selected based on local policy, arboriculture expertise, and practical experience. The council prioritises planting native species where possible, particularily in parks and open spaces, and also for street trees. However, we recognise the importance of species diversity to ensure climate resilience and to protect against the risk of disease or other environmental threats.

Tree planting on development sites is managed through interdepartmental collaboration and engagement with design teams. The council requires that comprehensive tree planting plans are submitted as part of planning applications and ensures that these plans are implemented on site.

Each year suitable planting spaces are identified across the county. Proposed planting sites are inspected for suitability, taking into account factors such as underground and overhead services, visibility lines, signage, traffic signals, and space for future growth including root development. If a site is deemed appropriate, a suitable species is chosen for planting, following the ‘right tree, right place’ principle. Careful selection of trees and planting locations is essential to minimise future nuisances and reduce maintenance costs.

Over the past two years this approach has resulted in the planting of over 7,000 trees throughout the county, along with 34,775 native whips as part of the Mini Woodlands programme.
