Acer Negundo New Future for a Forgotten Tree

--The purpose of this paper is to identify the potentials of Acer negundo for renaturalization under midcity condrtions. --+The focus is on recent Montreal experiences. Acer negundo in the past planted mostly in its colored -leaf varieties, is hardly available anymore in the nurseries. Despite this, and despite the fact that Acer negundo is not native to our region, it has established an increasingly spreading population in the otherwise sparsely vegetated midcity district. This paper researches ways to make use of the valuable ecological potential of this species. Recommendations are made to reconsider the use of Acer negundo along with other "urban pioneerspecies" for ecologically founded and economically sound inner-city renaturalization efforts.
