CHRISTCHURCH ECOSYSTEMS

DRY PLAINS WET PLAINSThe Wet plains have changed drastically since human occupationand the effects of human activity has seen a severe loss oforiginal plant and animal species. The Wet Plains historicallysupported expansive podocarp (Kahikatea), wetland and swampforest. Riccarton bush is the only significant podocarp wetlandforest currently remaining. The honey eaters, tui and bellbirdwere important species for pollination and were all abundant inCanterbury in the past.

COASTAL PLAINSCoastal plains are divided into two broad ecosystems: theestuarine and the dunes. Estuaries contain complex ecologicalconditions due it being the point where freshwater meets the sea.Cycles of tides and freshwater inflow produce much variations ofwater levels and salinities which the vegetation must tolerate inorder to survive. Dune vegetation similarly are exposed to varyingsalinities and water levels, but also to extended durations ofdrought of which Pingao has especially adapted to.

The dry plains are part of the alluvial floodplain built up by braidedrivers of Canterbury. Prior to European settlement the plains werecovered with silver tussock grassland with localized woodland areasof Kowhai, Cabbage trees and Kanuka. Very few of these areasremain within the citys boundaries, with only a few shrubs, patchesof kowhai and areas of grassland surviving. The grassland areasare cable of supporting an extensive number of indigenous plant,bird and insect species.

Leptospermum scorparium

Manuka and kanuka were once common shrubland plants ofthe canterbury plains but numbers have significantly decreasedas Christchurch city has developed. However, Maori andPakeha settlement did cause a shortlived increase in theirnumbers. Manuka is a bushy shrub seldom growing tallerthan 5m. Its bark sheds in long papery strips ideal for manyinsect species, while after flowering it also produces smallwoody seeds. Historically the bark was used by Maori andEuropean settlers as a poultice for colds, flus and stomacheache due to its antibiotic properties. Its small pointed leaveshave also been used to make tea. Manuka flowers have anover represented pollen type that has a higher than normalconductivity about 4 times that of normal flower pollen. Thishigh conductivity indicates the high mineral content of thepollen.

Orange-fronted, yellow-fronted and red-fronted

Kakariki parrots have become increasingly rare in canterbury

with the orange-crowned parakeet (exclusive to canterbury) now

highly endangered with less than 200 remaining. They prefer

tall unbroken forrest such as the lowfoot hill beech forrests

of the southern alps and the dwindling podocarp forrests of

Christchurch. However, they are know to fly great distances to

reach manuka and kanuka trees for there antibiotic qualities.

By using the bark and leaves of Manuka trees these rare

parrots were able to rid themselves of parasites, and improve

the condition of their feathers. They feed largely on berries

such as fuchsia, mahoe and tutu, as well as the seeds of

plants like karo, toe-toe and flax.

Fuchsia is a tree native toNew Zealand and part of theOnagraceae family. It is oneof few deciduous trees nativeto New Zealand bush andis common in damp forestmargins and regeneratingareas. It produces large bellshaped flowers changingcolour from blue to red asthey mature, while alsoproducing large egg shapedberries.

Tui, Bellbirds and Kereru are all birdsnative to New Zealand known primarilyas honey eaters due to there preferreddiet of flower nectar. However, theyhave a very diverse diet includingthe berries of fuchsia, coprosma andcabbage trees. They are considered tobe the most important seed distributorsof native new zealand trees due tothere abilities to eat the largest berriesand fruit as well as various smallervarieties.

Bees create honeyfrom the pollen ofthe Manuka andKanuka tree flowers

Manuka honey is producedin New Zealand from bothmanuka and kanuka flowers.The honey is dark colouredand strongly flavoured with aherb and woody characteristic.Manuka honeys antibacterialproperties are almostexclusively caused by itshydrogen peroxide content.

OBJECTIVE SPACE FACIALITY

CLASSIFICATION

The classification system intendsto dissect the ecosystem drawingshelping to develop a series ofoverarching types within thedrawing set. This classification

system includes seven convergingcategories where the drawingspecies are formed.

(single - multiple:connected or separated)

Enclosed areas can occurin isolation identifyingan individual structure.In contrast a series ofunconnected spaces maybe established, relating toseries of individual structureswithin a combined area.Alternatively they mayform in clusters creatinga juxtaposition of severalstructures.

(single face multi face)

Similarly each line can beviewed predominantly fromone side or from several.Where this constitutes asurface a line primarilyviewed from one side islikely a ground surface. Onthe other hand where a linedivides space within thecomposition it may constituea surface that can be occu-pied in more than one layer,e.g. inside and outside orlevel 1 and 2.

(enclosed open)

This first division separatesthe drawings into twomajor lineages. If thecomposition of appearsopen and continuous itcorresponds to a projectwhose primary function is tocreate a connective ground.If the drawing compositionappears to enclose spaceor have a definitive edgeit correlates to a structurewhose principal function is todevelop an enclosing surfaceor structure.

The high office density proposed for the core will restrict the design variation within this central area. This proposed site is on the outskirtsof the core linking it out and across the avon river to the Christchurch art gallery, where there is slightly less design and building constraints.This area is also still currently active and used by the public due to its close proximity to other minor art gallerys and institutions, eg. the artscentre and Coca gallery, aswell as schools, restaurants and cafes. This provides an opportunity to draw people across both into the core andout towards the art galleries. Along with this position it also lies in line with both Woomin and Angelas sites allowing us to create a greenaxis through the city, extending the notion of a garden city outside the constraints of the proposed frame.

Motive - Due to the large amount of both small and large offices destroyed in the earthquakes new work spaces are required particularly for smaller firms,and the large number of design and construction firms required to effectively create a new Christchurch. To successfully bring life, creativity anddiversity back into the city center, new infrastructure needs to establish communities of social typologies. By creating a symbiotic system of spacesfor work, interaction, relaxation and circulation new vibrant, productive communities will emerge throughout the skeleton of Christchurch.

Following on from my investigation and group research the following conceptual schemewas choosen. By creating a series of site ecosystem drawings morphing one structure intothe next a multiplicity of structures fill the site informing program organisation, circulationand form. The following pages show these conceptual experiments.
