Animal Control

Due to the lack of design considerations to prevent birds, there have been occurrence of birds nesting. With increased forage and nesting opportunities, green walls have actually promote conservation of urban bird populations. There have been a study in the UK that recorded increased bird activity on and around green facades with climbers compared with bare walls. Birds were observed in the green wall searching for insects while their prey is still inactive due to low temperatures in the morning. The issue of control or preventing animal interaction with VGS for plant survival must be taken into account.
