Multifunctional, Scrubby, and Invasive Forests?

  title={Multifunctional, Scrubby, and Invasive Forests?},
  author={Christian A. Kull and Jacques Tassin and Haripriya Rangan},
Abstract Australian bipinnate acacias, known locally as mimosa, are widespread on the plateaus and mountains of Madagascar. Rarely, however, do these trees attain their full size, leading to a surprising landscape of ‘scrubby’ wattles. We review the introduction of the wattles, survey their multiple uses in rural livelihoods and environmental management, and analyze the forestry policies, tenure rules, and ecological factors that maintain the trees' scrubby state. This well-adapted plant is an… Expand
Australian acacias: useful and (sometimes) weedy
Flaws in Low’s case that all wattles should always be judged dangerous are addressed, and who should make judgements—and on what basis—on whether people can diffuse plants across ecological barriers are addressed. Expand
Taming the wild and ‘wilding’ the tame: Tree breeding and dispersal in Australia and the Mediterranean
This work compares and contrast the processes of transfer, dispersal, and genetic changes of these trees, with particular attention to crop-feral-wild complexes in both their home ranges and in introduced areas. Expand
Divergent perceptions of the 'neo-Australian' forests of lowland eastern Madagascar: Invasions, transitions, and livelihoods.
Policy-makers and managers need to be more reflexive on the ways in which environmental problems are framed and to put those frames more in conversation with local people's experiences in order to productively resolve invasive species management dilemmas. Expand
Acacia exchanges: Wattles, thorn trees, and the study of plant movements
A three-part approach to analyzing plant movements and applying it to trees from the Acacia genus exchanged between Australia and the rest of the world allows to see transferred plants as active agents in region-forming processes, and to avoid normative tropes like ‘miracle plants’ or ‘alien invasives’.
