Mini Forests

Initiated 2024

Proposed in our 2024 Community Biodiversity Action Plan this is an innovative approach to urban greening and biodiversity restoration

Our Proposal

To plant a series of fast-growing mini urban forests to boost biodiversity, create wildlife habitats and corridors, absorb carbon and freshen the air with oxygen, manage the groundwater, bind the soil, improve rainwater drainage, provide cooling summer shade and soil warming winter leaf mould, provide privacy and screening from the wind & traffic noise, reduce residents' lawn maintenance costs, and add aesthetic and recreational value to Johnstown.

Modeled on the Miyawaki method, Mini Forests are quick-growing, densely planted, small urban forests.

Typically only the size of a tennis court, 200 sqm, they create habitats for wildlife, improve air quality, and promote environmental awareness within urban areas.

Using native plant and shrub species, and accelerating growth, these miniature forests require minimal maintenance and reach maturity in a fraction of the time of traditional forests.

These forests could become self-sustaining, maintenance & cost-FREE in only 3 years.

Our Existing Woodlands

Individual trees offer some environmental and social benefits, but they pale in significance compared to large mature woodlands that provide better opportunities for biodiversity, and we host two areas:

River Boyne

Accessible via rough tracks Johnstown has a 2km long stretch of natural native woodland at the Athlumney Riverside. Part of a protected Site of Special Interest our Community Biodiversity Action Plan 2024 pays special attention to it.

Sections of mature woodland sit alongside newer self-seeded areas and open grassland of the flood plain.

2. Metges Road

A natural min forest self-seeded thirty years ago opposite the Peoples Park. The 10,000 sqm strip runs alongside the IDA and follows the historic boundary hedge of Metges Road. Had the area been planted using the Miyawaki method it could host 30 to 50 thousand trees!

Valued at over €1M the privately owned land has frequently been proposed for development into apartment blocks and a supermarket.

New Areas ?

Housing Estates are the Key.

Johnstown hosts approximately 267,000 sqm of public grass lawns, excluding roadside verges. This is the equivalent of 22 soccer pitches or every house gaining a 10m by 10m front garden extension! Our sights are very much set on some of these huge estate grass lawns.

These areas are currently considered a burden to those residents who contribute to the cost of grass-cutting. Mini forests can quickly become both maintenance and cost-free, and contribute to our green neighbourhood image.

Public Lawns Map and we have not included the IDA land that is farmed for grass.

Trees can provide a boundary edge, create features that enhance the existing space, frame views, shield us from winds, provide noise barriers, and add privacy. These pockets of woodland are small and dense. Consider them like planting beds for tall trees, but unlike natural mature forests, these will initially not have any footpaths between the trees.

Native Trees

A forest has 3 distinct layers, and the following species are well-suited for County Meath

🌲 Canopy Trees (Tall / Dominant Layer)

Sessile Oak, Dair ghaelach

Prefers upland, acid soils but tolerates most.

Pedunculate Oak, Dair ghallda

Better on richer, lowland soils (like Meath).

Scots Pine, Péine Albanach

Technically native (reintroduced); drought-tolerant.

Birch (Silver & Downy), Beith gheal / Beith chlúmhach

Pioneer species, good for colonising open sites.

Alder, Fearnóg

Thrives in wet, riverside or boggy ground.

Ash, Fuinseog

Good on limestone soils (widespread in Meath); note: ash dieback risk.

Wych Elm, Leamhán sléibhe

Rare now; suitable in moist, fertile soils.

Rowan (Mountain Ash), Caorthann

Hardy, light-loving, tolerant of poor soils.

🌿 Understorey / Small Trees

Hazel, Coll

Excellent coppicing tree; thrives in Meath’s lime-rich soils.

Holly, Cuileann

Evergreen; good in shade, berries for birds.

Spindle, Feoras

Colourful berries; likes calcareous soils.

Guelder Rose, Caor chon

Attractive flowers and fruit; prefers damp soils.

Wild Cherry, Crann silíní fiáin

Lovely blossom; good for pollinators.

Bird Cherry, Silíní éan

Suits damp woodlands.

Crab Apple, Crann fia-úll

Fruit for wildlife; flowers in spring.

Whitebeam, Fionncholl

Rare native; tolerates dry soils.

Small-leaved Lime, Teile

Very rare, but native; good for insects.

🌾 Shrubs / Hedgerow Trees

Blackthorn, Draighean dubh

Excellent wildlife hedgerow plant; early flowering.

Hawthorn, Sceach gheal

Key Irish hedgerow species: white blossoms.

Elder, Trom

Fruit and flowers used for food; quick growing.

Dog Rose, Feirdhris

Thorny hedgerow climber with pink blooms.

Buckthorn (Alder & Purging), Paide bréan

Rare but native; food for Brimstone butterflies.

Bramble (Blackberry), Dris

Technically a shrub; key food source for birds and insects.

Forest Themes

Oak Grove

Dominated by sessile oak, hazel, holly

Butterfly Forest

Mixed rowan, willow, wild cherry, honeysuckle

Wet Patch

Alder, willow – for damper low spot

Berry Hedge Forest

Hawthorn, elder, blackthorn, spindle

Wildlife Refuge

Add log piles, bug hotels inside

Kids Forest

Open understorey, great for exploring

Pollinator Strip

Blend of native forest edge & wildflowers

Organisations

We're not the first group looking to create Mini Forests, and we can join a group to guide us through the process.

🌳 Stepping Stone Forests

A not-for-profit urban mini-forest initiative based in South Dublin, inspired by Prof. Akira Miyawaki’s method of dense, multispecies native planting. Inaugural forest in February 2022 at Old Bawn Community School in Tallaght—consisting of 475 native trees and shrubs, has since planted over 3,600 trees in seven schools and 2,500 more in public spaces like Sean Walsh Park and campuses in Blanchardstown and Tallaght. In collaboration with South Dublin County Council (SDCC) and local community groups, they've planted over 16,000 native mini-woodland trees across 36 locations, with more than 1,500 volunteers participating https://steppingstoneforests.org/

🌳 Pocket Forests

Based in Dublin, Pocket Forests is a social enterprise that collaborates with communities to plant small native woodlands in urban areas. They've established over 75 pocket forests across Ireland, including projects at Trinity College Dublin and the University of Galway. Their approach involves community participation, often utilizing saplings grown in their own nursery at Shelton Abbey Open Prison. These forests can be as compact as a single parking space, making them ideal for schools, businesses, and neighborhoods. dcc.ie+6Irish Examiner+6LinkedIn+6 Pocket Forests

🌱 100 Million Trees Project

This ambitious initiative aims to plant 100 million native Irish trees over the next decade using the Miyawaki method, which involves densely planting a variety of native species to create fast-growing, biodiverse mini-forests. They've already planted over 750,000 trees at more than 100 sites, including locations like Glenstal Abbey and Áras an Uachtaráin. The project welcomes collaborations with landowners, schools, and community groups interested in hosting a mini-forest. filles-de-la-charite.org+3Forestry Services Limited+3100milliontreesproject.ie+3 RTÉ+3Forestry Services Limited+3National Catholic Reporter+3
