Endangered species uk
2 Answers
In order to be classed as endangered,to what levels must numbers of a species sink?I'm referring in particular to the ubiquitous Great Crested Newt whose presence has yet again sunk plans for a hospital development near my home.There are 18000 sites in the UK where they reside-that doesn't really seem endangered to me.

Difficult question. The 18000 possible sites is an estimate only. 3000 have actually been identified. Sites this particular newt needs for breeding are deepish ponds with a decent amount of aquatic vegetation. These are being lost at a fair rate- filling in accounting for some and neglect accounting for the rest- silting up, becoming stagnant. Although Britain has a reasonable population of this newt compared to some European countries, the critria here is breeding sites- are they close enough to allow a decent gene pool, is the population actually large enough to be self-sustaining.
