Old Broom is a 6.5-hectare (16-acre) nature reserve north of Risby in Suffolk.

It is managed by the Suffolk Wildlife Trust.

[1] This is a remnant of an ancient wood-pasture landscape with oak pollards between 250 and 500 years old.

The dead wood and hollow centres of these trees provide a habitat for fungi and invertebrates, while the bark hosts mosses and lichens.
