3 Factors To Be Considered When Designing This Strategy
Maintenance
• To be kept at a minimum to ensure strategy is advantageous to the area
Species
• Different species have different effects on the pollutants
Placement
• Can be the difference between a highly efficient and a less efficient solution

1. Maintenance
– To be kept at a minimum to ensure strategy is advantageous to the area
Protection
• Tree seedlings need to be protected in its early stages against insects and human stepping on it
