Campaigners are fighting to stop the government selling off Sulham Woods, near Reading.
Berkshire Save Our Woods has called a protest on Saturday 5 March.
Mass opposition has led to the government temporarily stopping the sale of around 15 percent of public forests.
But a huge threat to forests remains and activists need to keep piling on the pressure.
