The herbage and associated habitat factors of 15‐ to 20‐years‐old reclaimed hill pastures were investigated in Mid–Wales. These swards had been reclaimed from natural hill vegetations by ploughing and sowing. The results were examined to determine which habitat factors were associated with sward reversion. Particular emphasis was given to determining how far reversion was under the control of the farmer. On ill‐drained soils the swards became heavily infested with Juncus effusus , regardless of management. On well‐drained soils reversion was largely prevented by maintaining an adequate stocking rate in summer, coupled with periodic applications of lime and basic slag. Inherent podsols required approximately twice as much lime as inherent brown earths for the equivalent maintenance of soil pH and sward composition.
