When faced with competition from Grey Squirrels, Red Squirrels have been shown to compete for longer in conifer forests with a mix of tree species and a diverse age structure of trees to ensure continuity of food. The presence of large-seeded broadleaved trees (oak, chestnuts, beech and hazel) aids Grey Squirrel colonisation and threatens Reds.
The national survey of 1989-90 located water voles at 75% of Merseyside sites. A 1999-2000 survey found water voles present in 53% of all suitable North Merseyside locations. Liverpool has little suitable habitat for water voles, whereas 75% of sites in St Helens were positive.
