Forestry England says it is assessing what the government's latest advice and guidance means for its programme of live summer concerts.
Westonbirt Arboretum, near Tetbury in Gloucestershire, is scheduled to play host to four concerts between June 11-14.
Organisers say they will publish information online and contact ticket holders directly with any updates.
Rag N' Bone Man, Will Young and James Morrison, Madness and Keane are all set to perform.
Forest Live stages music in several UK locations and income from ticket sales is put towards looking after woodlands sustainably.
