What are upland hay meadows?
Hay - Grass is primarily annually cut to procure fodder for livestock.
Meadows - small to medium-sized grasses with wildflowers
Upland - found on Moderately sloping sites between 200m and 400m altitude.

They are commonly confused with grasslands, but upland hay meadows are
Flowering grasslands with a rich diversity of species
Cut annually for hay, keeping them short & medium-sized
Can vary from half an acre to hundreds of acres

And they do not have TREES! (why? Well, it's too cold or snowy for trees to grow
However, climate change is causing these natural meadows to get overrun by trees.)

The main picturesque feature is that they are covered with white pristine snow during the winters, blooming with bright flowers during the autumn, and lay with monochrome yellow ochre shades in summer, ready to be cut for hay.
The community occurs in northern England, where many examples are in enclosed fields in upland areas, especially the northern Pennines - they occur as small patches on roadside verges, riverbanks, and hill slopes, but some occurrences are in enclosed fields within upland areas.
