Vegetation
From Tardis Wiki, the free Doctor Who reference
Vegetation referred to the plantlife covering a planet or area. (TV: Nightmare of Eden)
Within the petrified jungle on Skaro, the First Doctor observed that the vegetation had been destroyed. After the Thal-Dalek battle, he noted that the soil was healing and might birth new vegetation soon. (TV: The Daleks) When he returned to Skaro, fifty cycles later, vegetation had begun to return to Skaro, beginning to overtake the abandoned Dalek City. (AUDIO: Return to Skaro)
