Green Infrastructure Research
In this project, a site analysis was done to examine the exisiting green infrastructure, the vegetation, the soil samples, historical
remnants and the landowners and different residents in University College Dublin.
Green Infrastructure
- The Green Infrastructure services that have been highlighted are the agricultural services, the recreational services (sports),
the woodlands, the new lake and the old lake.
Vegetation
- There are five woodland walks in UCD: The Mellenium Walk, the Rosemount Walk, Glenomeena Walk, Belfield Walk and the
Boundary Walk.
- Some of the trees in the UCD campus include Nooka cypress, Giant Sequoia, Wellingtonia, Turkey oak, Field maple, Fox-
glove tree and Scots pine.

GREEN INFRASTRUCTURE IN UCD
IMPROVING BIODIVERISTY WITH GREENROOFS
How can the GI be Improved?
UCD is known for its excellent green infrastructure network. However it can be improved. The introduction of green roofs into the campus would be a way in which we can improve the biodiversity on campus, protect the
existing habitats and give an overall better experience for students, staff and visitors.
Other ways that can be improve the green infrastructure network on campus is urban farming, botanical gardens and rain gardens. These are stepping stones for improving wildlife. The main focus will be green roofs.
Ireland’s Biodiversity Action Plan Masterplan of New Interventions
This consists of:
1. Mainstream biodiversity into decision-making across all sectors
2. Strengthen the knowledge base for conservation, management and
sustainable use for biodiversity
3. Increase awareness of appreciation of biodiversity and ecosystem ser-
vices
4. Conserve and restore biodiversity and ecosystem services in the wider
countryside
5. Conserve and restore biodiversity and ecosystem services in the marine
environment
6. Expand and improve management of protected areas and species
7. Strengthen international governance for biodiversity and ecosystem ser-
vices

Perennial planting is an excellent source of nectar for pollen and nectar
They are also:
- Low maintenance
- Easy to establish

ROOFS FOR BIODIVERSITY ONLY
Roofs for Biodiversity Only Bird Species being Protected
These greenroofs will be for biodiversity only. These patches will allow for the existing habitats to interact with the new habitats in the greenroofs.
Not only are the different habitat being protected and the biodiversity is being improved, but the issue of habitat fragemnetation will be resolved.
Due to the type of planting that is going to be used in these roofs (wildflowers and perenniasl), the soil isnt going to be very heavy and overall the
buidling will be able to support the green roofs.

- Can survive the local climate conditions and protect wildlife

Rain Garden
The Green Infrastructure elements in this design have would streng-

regualting services are improved because the air quality, runoff and
pollination is improved with the application of the green roofs and rain
gardens. Provisioning services are also imporved due to elements such
as the urban farm. The application of all of the new elements will attract
more people into the university and overall improve human health and
well-being.

Lutyens was greatly inspired by the work of Gertrude Jekyll
(1843-1942) for his design of the rose garden. The garden as
a whole consists of a yew hedge surrounding the garden, and
various beds and bushes of roses and a herbaceous border.
The herbaceous border allows for an colourful display during
the spring and summer times.

Purpose of a Rain Garden Plant Selection Process
The function of a rain garden is to prevent rainwater runoff after downpours. They are:
- Low maintenance and require no watering once the plants have been established.
- Can absorb up to 30% more water than a lawn. Species that are being enhanced
- Can allow for oppertunities to plant a wide range of perennials.
- Attracts a wide range of wildlife and creates new habitats.

Plant Conditions: Common Plant Characteristics:
- Well-drained soil - Hardy or partially hardy
- Clay/loam/sand/chalk soils - Perennial
- Full Sun or partial shade - Herbaceous
- South/West/East facing - Mostly flower June through November
When selecting the plants for my rain garden, I wanted to choose plants that were versatile and plants
that were good all year round. The plants that were chosen also survive under the same conditions so
that maintenance is easy.
Visual impact is very important as well for both the ornamnetal garden and the rain garden. For this rea-
son when choosing my plants I tried to consider:
- Colour (Colours that complement each other well)
- Texture (Interesting plant texture all year round)
- Shape
- Height (Different heights may also have strong visual impact)

Flowering Times
The chosen plants for this design are very diverse. Theres a mixture of wildflowers, shrubs, herbaceous plants and perennials. Some of the plants are vergreen and some are deciduous. I wanted to choose plants
that would have an incredibly interesting display all year round. A very colourul display would be present mostly during the Summer and Autumn and a more greyish, skeleton-like display would be present during
the Winter and early Spring time.
The main colours that would stand out all year round are red from the Cornus alba and greens from the evergreen Lobelia grandiflora.

and have beautiful foliage throughout the year.

Purpose of an Ornamental Garden Plant Selection Process
The purpose of an ornamnetal garden is to provide an aesthetically pleasing space for people to improve
well being and to attract wildlife. They:
Species that are being enhanced
- May be used for the production of crops and other produce.
- Give an oppertunity to create new habitats and improve the existing ones.
- Include grasses, shrubs, flowering plants, trees and bulbs.

For the ornamental gardena wide variety of plants were used. Similar to the rain garden, alot of visual
impact will be given from this garden through several elements- colour, texture, shape and height. The
colours in this planting scheme mostly consist of very strong blues and purples given by the Agapathus,
Delphiniums, Bergenias and Lavender. Again, the plants chosen were selected to survive under the same
considtions.
The designs for my rain garden and ornamnetal garden were inspired by Piet Oudolf work.

The reason why I chose this tree in particular to plant
