 SCP-540 denotes a collection of Soviet-era explosive ordinance. All instances can be detonated in the same manner as non-anomalous examples. Approximately 35 to 37 seconds following the detonation, a mass of plant life will rapidly grow to cover the majority of the damaged area. All testing to date has resulted in plant life covering a minimum of 90% of damaged areas. The initial growth rate of the plant life is positively correlated to the yield of the originating explosive, but returns to normal for the plant species after approximately 90 seconds. There are currently instances of SCP-540 in Foundation possession and an unknown number outside of Foundation control.
