“Everybody that met her loved her and she'll never know the positive effect she had on their lives. She was very passionate about the natural world, loved to play guitar and sang with the voice of an angel.
“Holly will be missed by everyone and our hearts will be forever broken."
Holly was a former pupil of Cardinal Allen Catholic High School in Fleetwood, where she was the international lead for a wildlife project supporting the world's bee population. She was a committee member for CardyHoney, collecting and selling honey from the school's four hives to help fund green spaces campaigns locally.
Her teacher Sally Hughes said: "This is so heartbreaking. I taught Holly and she was the kindest and most caring of pupils. My thoughts are very much with her family and friends. So very sad.
Brendan Bunting, who runs a youth group in Blackpool, which Holly was a part of, said: "Holly was a special young person who gave so much, cared so much for others, and contributed so much to her community to benefit other young people."
An inquest into the teenager's death will open at Blackpool town hall on Friday.
