As reported in the February 2005 minutes, several non-domestic trees were recently planted in Pilrig Park. The potential problem is that invasive non-native species can do a lot of damage. The management problem was that due to the approaching end of the planting season, the relevant Edinburgh Council department decided to plant without consultation.
