Pattern in Design
The world is a sequence of events within a pattern. All things spiral through the pattern. In pattern application, there are two aspects: 1) the perception of the patterns that already exist (and how these function), and 2) the imposition of pattern on sites in order to achieve specific needs.
Zone and sector planning are examples of pattern application.
A) Edge effects and harmonics
Edge effect: the interface between two ecosystems represents a third, more complex system which
combines both. The interface, or edge, receives more light and nutrients and so is more productive.
Harmonics and area: increase in linear effects while the area is constrained.
Low productivity (square, circle pond): productivity increases as the shape of the pond is changed to produce more “margin” or edge. The number of plants around the edge may almost double, and so may the number of fish since they are mainly marginal feeders.
Other examples of patterning with edge include:
• Circle garden rather than linear garden (saves space and water)
• Trellis on zig-zag pattern rather than straight line
• Crops planted in strips and contours with companionable crop in between strips (crops receive more light for photosynthesis and yield is high for both)
• Windbreak can be planted either to deflect wind or to funnel it into a gap for wind power.
• Gardens can make use of “keyhole” pattern to maximize space and yield.
Species edge possibilities are determined by whether plants/animals are compatible. E.g. wheat planted
with Lucerne (alfalfa) will increase yield, while yields decrease if planted with Brassica.
B) Flow Patterns
Can use pattern in river flow to scour deep ponds, to accumulate mulch on edges, and to build up a layer of silt.
Mulch and silt accumulate during the flood phase of the river, but trees must be planted to catch this accumulation.
