Ninesprings Country Park covers approximately 8 hectares (20 acres) in the southwest of Yeovil.

The site lies on Yeovil Sand (a yellow micaceous sand) of the Upper Lias (in the Lower Jurassic Period of the Mesozoic Era, formed some 160 million years ago).

The origins of the present habitats are obscure but the site is believed to have been developed as an ornamental park, for the Aldon Estate, “in the early nineteenth century”. The sizes of the few remaining oldest trees, together with the sizes of the stumps still evident from the 1964 felling, suggest that the original plantings were probably around 1830. .

The main features of the site are as follows

1. The primary habitat is well-established, old woodland consisting of a mixture of standard broad-leaved trees with a few standard coniferous trees, some of these trees being extremely fine specimens the size of which suggests that they are over 150 years old; the overall habitat is technically broad-leaved woodland since the coniferous trees form less than 10% of the total.

2. There is an extensive understorey of cherry laurel (presently being reduced) with additional shrubs particularly of hazel and young wych elm.

3. The site is situated on a fairly severe slope (rising from approximately 34 metres above sea level on the northern side to approximately 86 metres on the southern side) with numerous, small exposures of the Yeovil Sand.

4. There are several active springs on the east side, resulting in a good flow of water northwards in a deep gully; this enters a pond in the northeast and there is a subsidiary small pond to the west of the main water body; on the northern boundary, a stream runs from east to west, accepting water from these ponds.

5. In the northern part, the site has a more open aspect approaching parkland with areas of grassland and field vegetation.
