With these wide fluctuations in the average NDVI the the over all average for the whole year in 2018 was 65% (n=372 monthly observations), 5% lower than the mean vitality core recorded in 2019.
Not only was the average NDVI highly variable as the season progressed for the reasons already explained but the maximum and minimum observations in the data illustrate just how diverse the vitality of grass is across golf courses in Great Britain.
There is some evidence to support the assumption that at regional level what is normal in one part of the country is far from the experience of green keepers in another part of the country. The chart above shows that the North East delivered the highest NDVI score, and Scotland the lowest!
