Material: Earthquake, Squirrels, Carbon animals, RHS 24 Feb 11

Before the earthquake in New Zealand last September, the fault line it occurred on wasn’t known about. Following the damaging and deadly aftershock, there are concerns whether the whole area is much more vulnerable than we previously thought. Quentin is joined by Dr Elisabetta Mariani, who has just returned from drilling the major fault line in New Zealand. Two thirds of people in the UK now think that grey squirrels should be controlled or even removed- according to a survey by the European Squirrel Initiative. Quentin finds out more from Dr Craig Shuttleworth. Tiny Antarctic marine creatures collected 100 years ago by Antarctic explorer Captain Robert Falcon Scott give new clues about change in polar animals. Dr David Barnes, joins Quentin to explain more. The Royal Horticultural Society is announcing a new campaign to raise nearly £600,000 for a new research facility. It is the only independent organisation that funds research into gardening. Dr. Roger Williams explains more.
