Abstract
The residential district Bo01 in Malmö, south Sweden, was built in the years
2000-2001 on former industrial land. Measures have been undertaken to
counteract the negative impact of urban sprawl on the ecosystem. Houses are
built close together to use the land efficiently. Still, it is a green district, thanks to
two planning instruments, green space factor and green points, e.g. a majority of
the buildings have green roofs. The greening of the area aims to present an
attractive green surrounding for people, promote biodiversity, and minimise
storm water run-off. Storm water is managed in an open system which includes
ponds with native vegetation. The green space factor means that different types
of surfaces are given different credits. Plant beds, climbing plants, green roofs,
and ponds are given high credits. No credit is given to sealed surfaces. The green
points include for example: a bird nesting box for each apartment, a courtyard
containing at least 50 Swedish wild flower species, food for birds all year round
in the yard. In the parks, semi-natural biotopes have been built comprising
meadow, oak and beech woodland, and alder carr. The soil and the species
composition of grasses, wild flowers, bushes and trees conform as far as possible
with their natural counterparts. Before the area was developed, sea birds such as
avocet and terns, nested on the old industrial sites. A compensation biotope for
birds will be created in the northern harbour of Malmö. Studies show that the
inhabitants are very satisfied with the quality of the parks and gardens.
Biodiversity is lower than in a similar, but older residential district that has been
used as a comparison. Biodiversity is expected to increase with time.
