I'm sorry Pete but it has to be said that your last post was an absolute load of old half truthed condescending cr4p!!
Otters were and have been in a postion where they could if conditions proved favourable to grow in numbers for over two decades.
They have had strong holds in areas all around mainland UK.
South Wales, Western Scotland and Northern England that I know of.
From these strong holds a population expansion would have been a very easily achievable goal naturally but for one consideration that naturally governs predators over populating any given area.... FOOD SOURCE!!
This lack of a sustainable food source is what had been holding back a population growth in otters, just a shame do-gooding interfering fools thought they knew better than nature itself.
Nothing stopping otters moving from where I'd seen them 25 years ago at Port Talbot east along the coast to the Severn estuary then 'naturally' up into the tributaries W. Avon, Teme, Wye etc.
You stated the Teme has always supported a population of otters. So why then did they not spread themselves further a field?
I posed that as a question though I'll answer it for you!
Simple really because the environment was not suitable, why?
Simple again, insufficient food resource for the population of otters to sustain such a increase in numbers!
For any species to thrive naturally three major objectives must be met. A suitable and abundant food source, evasion of predation and suitable habitat / environment.
Well the lack of growth in otter numbers should have shown that at least one of these crucial areas was a drift and in the UK there are very few species that will successfully predate a otter, so I'm guessing that its one or both of the other two criterium?
Again I should let you Pete to answer but I'll help you anyway.
If a new species (otters) is introduced into any given environment (our rivers). It is normal / usual to experience a rapid population growth.
Due to a lack of competition for food and territory. This coupled with easy pickings found in said environment (old fish), this just serves to exacerbate the sitsuation further because a now very overly inflated population of any given species (otters) will be left (as we are finding now) to find food (fish) but the problems in sustaining those food sorces are still there but then without any adult stock either....
Any bright ideas??
