Landscape architecture has an important role to play in the sustainable design of the city. Sensory gardens are those gardens that are designed to stimulate the senses, to do more than just look good, but to function on a human scale, providing food, shelter, habitat and employment. Urban forests can be the ultimate sensory garden, when planted with mixed natives, fruit and nut trees, and designed for year round interest, to attract native birds and invertebrates.
Urban trees represent an irreplaceable asset for cities, and unlike most municipal infrastructure a trees’ value will increase over its life span. In technical terms, an urban forest refers to the trees located within a city’s limits, whether planted or naturally occurring.
