Hazel Doormouse reintroduced. (1 Viewer)

What is the survival rate? How does that compare with wild-bred individuals?

Are the releases into improving or deteriorating habitat? Given that the reintroductions are necessitated by Dormouse (one "o") loss, what are the criteria for judging that the habitat will now support a population?

When does the project anticipate completing its release work, since that must be a success criterion?

(I'll be honest, I don't think this is a successful project, just a long-running one.)

I wonder if this is the same project?

Yes, its more PTES work. It would be interesting to see reports on what has happened in the places where the first hundred Dormice of the thousand to date were released: increase, stable, disappeared (again). Presumably there is monitoring.

As of 2016 the programme had released Dormice at 26 sites in 12 counties. Of these, 5 reintroduced populations have since died out while others have "achieved varying criteria of success, such as breeding or dispersing beyond the site to new areas".

So approximately 20% of the effort had at that time proved a complete failure (and more than that, speaks to an inability to identify sites ready for reintroduction). I didn't see anything about learning from experience or improved identification of success factors arising from the environment at prospective sites to generate a higher success rate (and I would like to know more quantitative measures of success than "tick - breeding" or "tick - dispersal": how much, how successful, population increase/stable/decrease over time and so on).
