Short description of the intervention
The likely impacts of climate change in South Dublin County include an increased risk of flooding, more frequent summer droughts, deteriorating air and water quality, and biodiversity loss (1). To address these climate challenges, the county developed the County Development Plan 2016-2022 as part of the South Dublin Climate Action Plan, aiming to establish a comprehensive legislative and policy framework for green infrastructure (GI) planning (1).
The plan outlines various objectives, including creating a coherent, integrated, and adaptable GI network across South Dublin County. One key initiative is the establishment of native mini woodlands throughout the city, designed to form strategic links and integrate the GI Strategy’s objectives into all relevant land-use plans and development across the county (1).
The purpose of these mini woodlands is to connect green spaces across the city (minimum size of 100 sq m), sequester carbon, and promote biodiversity in suitable locations, such as built-up areas, low-grade parkland, and other zoned areas deemed appropriate (1). Given the long time required for tree growth, the project employs the Miyawaki method, planting a high density of diverse native species to create mature forests up to ten times faster than traditional plantations (2). These forests are estimated to host 20 to 100 times more biodiversity and absorb carbon up to 40 times more effectively, without the use of chemicals or fertilizers; key factors include ground preparation, planting density, and species diversity (2).
In 2022, the project held a planting day for the mini woodlands initiative on Mill Lane, where 1,200 native trees and shrubs were planted with the help of volunteers from local schools, the community, a corporate group, and the Mayor of South Dublin, Councillor Emma Murphy (2).

Goals of the intervention
The goals of the mini woodlands project on Mill Lane as part of the larger county Green Infrastructure Plan were to:
1. To establish a coherent, integrated and evolving GI Network across South Dublin County with mini woodlands to form strategic links and to integrate and incorporate the objectives of the GI Strategy throughout all relevant land use plans and development in the County (1).
2. To develop linked corridors of small urban ‘Miyawaki’ native mini-woodlands, a minimum of 100 sq m in size, to capture carbon and encourage biodiversity (1).
3. To protect and enhance the biodiversity and ecological value of the existing GI network by protecting where feasible (and mitigating where removal is unavoidable) including woodlands (1).
4. Combat air and noise pollution, soaks up rainwater that may otherwise create flooding, creates a habitat for local wildlife, and to lift morale in the people who see it, calming traffic and lessen urban crime (1).

Implementation activities and NBS focus
Implementation activities
To realize the goals of the mini-woodlands on Mill Ln, the planting project involved a variety of activities including:

1. Setting GI targets in the South Dublin Climate Action Plan that involved incorporating woodlands into Council’s Tree Management Strategy (1).
2. Selected the project area consisting of 160 m2 and prepared soil to implement tree plantings at a density of around 5 plants per meter squared to promote growth and biodiversity (2).
3. Hosted a planting day for the implementation of 1,200 native trees and shrubs closely together to promote an underground root network and build a urban forest canopy (2).

Impacts, benefits
Description of environmental benefits
1. Enhanced carbon sequestration: "The benefits of a Mini Woodland Mitigates climate change through carbon sequestration. CO2 absorption is 30 times greater than grassland." (3)
2. Improved air quality: "Many of these open spaces serve as important hotspots for biodiversity, and the trees, forestry and woodlands they contain filter carbon and other pollutants, contributing to air quality." (1)
--Expected reduced noise exposure: " to plant hedgerows along roads to help mitigate noise and air pollution, and to increase visual amenity and enhance biodiversity" (3)
3. Improved soil quality: "This method grows mature native forests without the use of chemicals or fertilisers, and relies on ground preparation, planting density and species diversity as key elements. High planting density creates undersoil co-operation and above soil competition." (2)
4.--Expected increased ecological connectivity across regeneration sites and scales: "To develop linked corridors of small urban ‘Miyawaki’ native mini-woodlands, a minimum of 100 sq m in size, to capture carbon and encourage biodiversity in suitable existing built-up areas, in low grade parkland, and other areas of zoned
lands where deemed suitable and appropriate. " (1)
5. Increased number of species present: "1,200 native trees and shrubs were planted by the volunteers." (2)
6. Enhanced support of pollination: "The benefits of a Mini Woodland Provides Shelter for wildlife including nesting birds, pollinators, and other insects." (3)
7. Reduced biodiversity loss: "The benefits of a mini woodland mitigates biodiversity loss by creating diverse habitats that assist in the movement of species, and support genetic diversity." (3)
8. Increased protection against flooding: "The benefits of a mini woodland mitigates flooding through water retention, absorption and evaporation." (3)
