Having significantly impacted many areas, some attempts of restoration have been made.[1] In general, though, it takes some time for implanted methods to fully restore degraded grassland.[2] Also, there are certain ways that degraded land should be counteracted, depending upon its severity.[3] For an area that is lightly degraded, fencing, fertilizing, or weeding.[2] Fencing an area off allows for that plot of land to be reprieved from grazing until it reaches its normal, healthy state, in which no more patches of dead grass exist.[7] The earlier the problem is addressed, the easier it is to restore that plot of land.[5] In some cases, grazing can even be continued as long as its intensity is decreased and the situation is monitored.[4] For instance, a method as simple as seasonally rotating fields in which animals graze have been see as effective.[2] More structured efforts must be put into place to combat moderately degraded grasslands.[5] These actions include reseeding and rodent control, whose goal is not to extinguish that population but rather to manage it so that it does not further degrade the land.[5] Rodent control can be in the form of either shooting, sterilizing, or poisoning the rodents.[2] The administered poison must have a low toxicity so that it does not cause further damage to other animals or plants; a popular toxin that has worked well is Botulin toxin C.[5]
