The December 2017 edition of the journal Biological
Invasions is a special issue devoted to papers from a conference on urban invasions that was hosted by the Centre for Invasion Biology
(C·I·B) in November 2017.
Although urban ecosystems are hotspots for biological invasions, the field of invasion science has surprisingly given scant attention
to invasion dynamics and the challenges facing managers in towns and cities.
The special issue explores urban-specific patterns,
processes, impacts and challenges of non-native species. It aimed to synthesize knowledge on invasion dynamics in urban ecosystems worldwide.
The workshop was organized by the research coordinator of the Invasive Species Management Unit of the City of Cape Town’s Biodiversity
Branch, Mirijam Gaertner, John Wilson (South African National Biodiversity Institute and C·I·B core team member), and
C·I·B Director Dave Richardson.
The workshop, attended by 43 people from eight countries, gave special attention to the following questions: Are patterns and
processes of urban invasions different from invasions in other contexts? Why is it important to manage non-native species in urban ecosystems? What
are the special management needs in an urban context? How can we bridge the gaps between science, management, and policy issues concerning biological
invasions in urban ecosystems? [To read the Editorial which sets the scene for the 17 papers in the Special Issue, click
The papers in the Special Issue show that patterns
and processes of urban invasions differ in many ways from invasions in other contexts, and that managing invasive species in cities poses unique and
increasingly complex challenges.
