| This is the view adjacent to the 11 acre sailing lake in Fairlands Valley Park, Stevenage, some 20 km SSW of Royston. The Park has been voted as one of the top 15 free visitor attractions in the UK and consists of 120 acres of beautiful parkland in the heart of Stevenage. As well as being a venue for dingy, kayak, windsurfing and powerboat courses on the sailing lake, the Park hosts a varied selection of wildlife, including an assortment of wildfowl in the established reserve. Although it is only early March (4th at 1202 GMT) 2011 the buds on the willow tree appear to be well advanced, whilst the coloured stems of cornus stolonifera and salix alba are at their Winter best. This was a day of light winds and sunny spells, and at Royston a maximum temperature of 7.5°C was achieved (after an overnight minimum of 0.2°C), whilst sunshine for the day was 7.7 hours. | The Winter Garden in the University of Cambridge Botanic Garden (21 km NE of Royston) was coming to the end at its usual stunning seasonal display when this photograph was taken at 1236 GMT on 14th March 2011. The Winter Garden brings together Winter flower and fragrance with an array of coloured stems, bark and foliage texture in a shallow valley landscaped out of a level site open to the south to maximise the more restricted light available in Winter and to take advantage of the illumination of the setting sun to enhance the colours of the cornus and salix species. Fragrances at the entrances to the garden include lemon meringue scented honeysuckle, various viburnum, and the lily-of-the-valley perfume of mahonia japonica. At Royston on this day the temperature rose to a maximum of 13.0°C after an overnight minimum of 0.5°C. Sunshine of 10.5 hours was recorded. | This large expanse of arable land as seen from the B1039 road mid-way between Royston and Barley has been cultivated to a fine tilth for drilling and now awaits some much needed rainfall to assist germination and to protect the soil from its vulnerability to wind erosion in this exposed location. The picture was taken on 24th March 2011 at 0900 GMT and so far this month only 1.6 millimetres rainfall has been recorded, this being only 5% of the average rainfall to this date in March. With the preceding drier than average February the soil is now in a very dry state indeed, as can be seen. The view is looking northwards to the spur of higher ground on the horizon running from Hyde Hill to Goffers Knoll. A light WSW wind of mean speed 1 knot gusting to 2 knots is drifting across the landscape in a temperature of 8.8°C. The cloudless sky in evidence resulted in sunshine for the day of 11.4 hours. |
