Putting aside the effects of an unusually deep freeze in 2011 which killed significant populations of white and sweet acacia, survivability of the species studied matched the range indicated in the literature for both annual and cumulative mortality through year five. The authors also found that maintenance of newly-planted trees could be enhanced through stewardship education and financial support for lower-income families.
