Street Trees

Urban trees have a positive impact for human health with research showing they have a benefit on asthma, stress related illnesses and even skin cancer. They also provide a number of psychological benefits.

Research has shown a 60% reduction in exhaust fume particles etc in streets which have urban planting. For every 10% increase in tree canopy the ozone is reduced by 3-7%.

One mature tree can produce the same cooling effect as 10 room sized air condi-tioners. This makes urban trees an effective tool in reducing hot spots within an area and can save up to 10% of local energy consumption.

Design Precedents

Design ProposalTo develop UCD into an ecological campus by adding new vegetation throughout the campus, bring UCD from grey to green.

Seating Space

I designed this outdoor seating space to attract students out into the landscape as they take breaks from their work. Each area would be designated with a unique array of planting from trees to shrubs. It could be seen as a place for students to study while outdoors or simply relax within nature. I wanted to create an area which stands out and grabs people’s attention as they make their way throughout the campus. I saw this as an excuse to introduce vegetation into areas which would otherwise be left bare.

Site Observation

One key issue with the ICON Office Park site which I noticed was the lack of wind coverage from the north. Upon visiting the site I found it extremely windy which created an un appealing space. An idea which I proposed to counter-act this issue was to incourporate a row of trees along the planting beds. I provided 3 tree options : Populus Nigra, Thuja Standishii x Plicata and Pyrus Calleyrana ‘Chanticleer’. These options all pro-vide great wind coverage as well as aesthetic qualities.

Island Gardens

These Island Gardens will enhance ecosystem services throughout the campus while also provid-ing an educational space for students. Each island (flower bed) will represent a different style of planting from perennial planting to wildflowers. They can be used by landscape architecture stu-dents to understand how different types of planting work together and how they can be arranged together.

As they are scattered throughout the campus, this will bring UCD closer to becoming an ecolog-ical campus with flourishing plants throughout. These gardens could be seen as focal points and bring UCD away from its grey infrastructure by provide an array of unique colours to the land-scape.

Planting PlanPerennial ‘Island Garden’

MaintenanceInspect for pests or problems•Look for leaves with holes, ragged edges, abnormally growing flowers, or damaged stems. Ifyou discover a problem, take samples of the damaged plant to a garden centre to identify theissue and gain advice.

Water•Dig into the top 2/3 inches of soil with a trowel. If the soil is dry, water until the soil is moist toa depth of 6 to 8 inches. Avoid wetting plant leaves late in the day to prevent the spread of plantdiseases.

Pull Weeds•Remove weeds as you see them on daily or weekly inspection. Ensure the weed is pulled fromunder the soil surface to prevent re growth.

Seasonal clean – up•In cold winter climates, protect tender plants with a loose layer of mulch. Cut back perennialsto within 8 to 10 inches of the ground to protect against the cold. In spring, cut back all deadstems and rake out debris.
