The area was the home of the Entwives who made their gardens there; but during the War of the Last Alliance at the end of the Second Age, they were driven away when Sauron ruined the land during the War of the Last Alliance, against the advance of the Allies down the Anduin. Thenceforth the area became a desolate desert. The Ents vainly had crossed the Anduin in search of the Entwives. Treebeard appeared convinced that the Entwives were not all destroyed but were "lost".
Even by the end of the Third Age, when seen by the Fellowship of the Ring as they drifted by in boats upon the great river, the Brown Lands were long, formless slopes with a withered look, having no trees or even grass. What had caused such desolation not even Aragorn could tell.
J.R.R. Tolkien describes in his unfinished index (for The Lord of the Rings) the Brown Lands as a 'translation' of Berennyn (containing Sindarin baran 'brown, yellow-brown') "a devastated region, east of Anduin, between Lórien and the Emyn Muil".
