Historique de l'introduction du genre <em>Eucalyptus</em> à Madagascar

Abstract: Une recherche documentaire a permis de reconstituer l'historique de l'introduction du genre Eucalyptus à Madagascar entre 1857 et 1889, et cela bien avant l'organisation des services forestiers de l'État. Plusieurs acteurs de différents pays ont procédé aux introductions de diverses espèces d'eucalyptus ; mais, à cette époque, l'identification des provenances d'origine des graines n'était jamais mentionnée. Ces introductions avaient notamment pour objectif d'assainir les régions humides infestées par le paludi… Show more

“…This entails removing the stems of tree species capable of re-sprouting from their stump, a property that has made several species of eucalyptus very popular in Madagascar. The large eucalyptus plantations around the capital (Antananarivo), including the Manjakandriana Massif, have been well-described [75]. Such coppicing appears in the change map as large magenta blocks around the black mass of the city in the northeast portion of the study area (Figure 2), interspersed with increases in woody cover (described below).…”

“…Second, urban market demand for wood fuel-particularly charcoal for urban consumers, or even to run industrial installations-as well as for construction wood, drives investment in woodlots [55,75,79,80,[84][85][86][87]. Several areas of the highlands contain landscapes particularly devoted to the production of charcoal, firewood, and wood products.…”

“…Palaeoecological data can also guide the species used in reforestation, providing information on former forest composition that could be used to select indigenous instead of exotic species (Wingard et al, 2017). Though Pinus, Eucalyptus and Acacia, are favored because of their high survival rate and rapid growth compared with many native species (Carriere and Randriambanona, 2007;Verhaegen et al, 2011;Kull et al, 2019;Randriambanona et al, 2019), these plantations are low in biodiversity and negatively impact soil and water provision provided by open and mosaic ecosystems (Charles and Dukes, 2008;Stickler et al, 2009;Bond, 2019;Kull et al, 2019).…”
