Plant Biodiversity of Urban Roadside Trees in Antalya, Turkey
Öz
Planting
trees in urban areas has a number of environmental, social and ecological
benefits, and roadside trees are an integral part of urban green space. Having a broad diversity of trees in urban roadsides can
guard against the possibility of large-scale devastation by both native and
introduced insect and disease pests. Urban foresters and municipal arborists
are advised to follow guidelines for tree diversity within their areas of
jurisdiction: (1) plant no more than 10% of any species, (2) no more than 20 %
of any genus, and (3) no more than 30 % of any family. The aim of the study was
to assess biological diversity on the five major urban roadsides (Atatürk Boulevard, Yüzüncüyıl Boulevard,
Hürriyet Street, Serik Street, Palmiye Street). The species are identified and counted. Face to
face interviews were carried out with landscape architects/municipal arborists
to understand decision making process on selecting and deciding the species to
be planted. Results showed that three
species and one genus do not fit to the expected ratio. Municipals lacked an
inventory list and a biodiversity scale for planning and planting in ratios
necessary to keep a diverse biological environment. Based on the shortcomings,
we would recommend to establish an inventory to do more informed decision
first, and plan new plantings in a way that would increase biodiversity in
species and genus level.
