In the absence of suitable plants, the eggs may also be deposited on leaf litter, stones, or even plastic bags. In the northern crested newt, a female takes around five minutes for the deposition of one egg. Crested newt females usually lay around 200 eggs per season, while the marbled newt (T. marmoratus) can lay up to 400.
Newts are semiaquatic, spending part of the year in the water for reproduction and the rest of the year on land. While most species prefer stagnant water bodies such as ponds, ditches, or flooded meadows for reproduction, some species such as the Danube crested newt can also occur in slow-flowing rivers.
The ponds and ditches provide habitat for breeding populations of great crested newt, which is a European protected species. Yellowhammer birds, a species on the UK red list of Birds of Conservation Concern, can be seen and heard in the bushes and hedgerows around the scrubland within the reserve.
In experiments allowing Italian crested newts to be exposed to nonylphenol, an endocrine disruptor common in leakage from sewers, there was a decrease in corticosterone and aldosterone, hormones produced by the adrenal gland and important for stress response.
A licence is required for surveying in ponds which contain great crested newts. [11] The site, known as Alton's Field, [12] was notified on 16 August 2000, [8] because "this site supports one of the largest known breeding populations of great crested newt Triturus cristatus in the UK."
The area supports a large variety of wildlife, including one of the largest populations in Britain of the nationally rare great crested newt. The Common is used for community events, Flower Festival, Race for life Cancer Research UK and formerly 'Power in the Park' hosted by Power FM .
