Shoreham Bank in late April 2005MILL HILLVetch Trail (Lower Slopes) : Shoreham Bank
45° ungrazed unimproved slope with an extensive Horseshoe Vetch in May and herbs and grasses below 40 mm in height

The lower slopes were so dominated by the Horseshoe Vetch that other plants could be overlooked. Of particular note were a handful of  Hound's Tongue, Cynoglossum officinale, (only the leaves have been recorded before) with most of the plants noted on the steep slopes just below the ridge.

These two miniature flowers of two separate creeping plants appeared amongst the herb layer on the lower slopes of Mill Hill:

The depth of field was limited by the poor light on an overcast day.The diameter of each flower was not measured but estimated to be less than 10 mm across. Neither of these small flowers were plentiful, and only one plant of each was spotted, although there could have been more.

It took until just after midday before I saw my first Small Copper Butterfly of the year on a clump of Devil's Bit Scabious with at least three Meadow Brown Butterflies, one Small Heath, and two Common Blue Butterflies all at the same time, at the northern end of the lower slopes of Mill Hill. A few Dog Violets and at least one Dropwort was in flower out of their normal spring season.

Butterflies numbered under a hundred in 25 minutes on the lower slopes including a total of 25+ Meadow Browns, 15+ Small Heaths, 10+ Common Blues, 1+ Small White, 1 Large White, 1 Small Copper and one Wall Brown (near the Wayfaring Bush by the path). One particularly worn blue butterfly, so worn it could not be identified, although probably a Common Blue, seemed to follow me wherever I went.

Dog Violet
Dropwort usually flowers in the spring

I think this is a dimunitive umbellifer in amongst the herbs. Unlike the Squinancywort (with four petals) these plants have five petals. I have identified this as Burnet Saxifrage.

The diminutive Scarlet Pimpernel. Are their signs of Rabbit grazing in this image? 
The small Autumn Gentian, or Felwort, is scattered amongst the herbs, but it does not appear to be any more than occasional this year

In the natural order (without man's interference) which plant will dominate? 

The dimunitive Squinancywort has four petals
It is widespread, but not abundant although very frequently found, in amongst the herbs
Agrimony grows as an upright plant next to paths, but a dimunitive form occasionally flowers amongst the herbs on the lower slopes.

Common Centaury is frequently seen amongst the herbs
Hound's-tongue, Cynoglossum officinale
is an early coloniser, in bare patches near Rabbit warrens and occasionally in bare patches on the lower slopes as well.

Verbascum thapsus

Burnet Saxifrage leaves

Wild Basil:  this common wayside plant occurs frequently on the lower slopes and is used as a nectar plant, although not the most popular one amongst the butterflies.

After the gales and late in the afternoon, it was unlikely that I would spot more than a handful of butterflies on the lower slopes of Mill Hill in the fading light. The butterflies could still be around but they had already chosen to roost and two Small Heath Butterflies were actually discovered roosting on two Devil's Bit Scabious flowers, so torpid that they did not fly off even when tickled. This was despite an air temperature of 17.8ºC at 5:00 pm.
