I know from experience that it's very difficult to develop a wild flower pasture which doesn't look a complete mess at some times of year - such as September when that shot was taken. At least they've made an effort when it would surely have been easier to simply grass those areas.
Getting back on topic, the PMI route from SEN this summer has an increased capacity of 40% with easyJet and over 100% with Thomson. It will be interesting to see if passenger numbers match those capacity increases.
