Some geography students have been conducting fieldwork in a local country park to investigate the environmental impacts of tourism and recreation.
As part of their study, they completed a Site Quality Survey at one of their sampling sites, shown in the table below.
| Quality Indicator | -2 | -1 | 0 | 1 | 2 | Quality Indicator |
|---|---|---|---|---|---|---|
| Heavy noise pollution | ✓ | Very quiet and peaceful | ||||
| Footpaths badly eroded | ✓ | Footpaths in excellent condition | ||||
| Little or no plant diversity | ✓ | Rich variety of plants and trees | ||||
| Litter bins overflowing/absent | ✓ | Excellent provision of litter bins |
What is the total site quality score for the country park area shown in the table above?
