Andy Mawson, from the GNAA, thanked the family and said it was "truly humbling" that they had supported the service "at such a horrendous time".
The family of a young girl killed when a tree fell on her at a school in Newcastle have raised more than £40,000 for the Great North Air Ambulance (GNAA).
The 6-year-old girl was taken to hospital from Gosforth Park First School on Friday and died the following day. Flowers and cards have been left at the gates of the school.
In a post on social media, her Mum said she wanted to raise money for the GNAA who had got to her quickly and did all they could to save her daughter.
Emergency services were called to the school on Friday afternoon. The child was taken to the Royal Victoria Infirmary in Newcastle, where she died on Saturday.
Northumbria Police have launched an investigation alongside the health and safety executive.
The school's headteacher said the entire community was shocked and devastated by the news.
A spokesperson for the force said: “At 1.15pm yesterday (Friday) we received a report that a child had been struck by a falling tree at Gosforth Park First School."
Chris Lowther, chief executive of the Tyne and Wear Fire and Rescue Service, wrote on Twitter: "I know the Firefighters who attended this tragic incident are deeply affected."
