  1. Reduce the intensity of livestock grazing in forests

    A replicated study in 1986-1993 in temperate woodland in the UK (Hester, Mitchell & Kirby 1996) found that reducing the intensity of sheep grazing increased the numbers of tree saplings. The number of saplings/100 m2 was higher in low-intensity (0.54-0.66) than in high- and medium-intensity grazing plots. Four plots for each grazing intensity: high (2.1-3.8 sheep/ha); medium (1.2-2.0 sheep/ha) or low (0.6-1.2 sheep/ha) were established in 1986. Saplings (>30 cm diameter at breast height) were monitored in 2003 in 20 quadrats (10 × 10 m) within each plot.

     

  2. Shorten livestock grazing period or control grazing season in forests

    A replicated study in 1986-1993 in temperate woodland in the UK (Hester, Mitchell & Kirby 1996) found thatusingsummer instead of winter grazing increased the number of tree seedlings. The number of seedlings was higher following summer (8-17/100 m2) compared to following winter grazing (4-6/100 m2). Six summer (May-October) and six winter grazing (October-May) plots were established in 1986. Seedlings (>1 year old, <30 cm diameter at breast height) were monitored in 2003 in 20 quadrats (10 × 10 m) within each plot.
