Layout of the Hard Hill experimental plots (R = reference, N = no-burn since 1954, L = long (20-year) rotation, S = short (10-year) rotation.
Table 2.
Summary of past surveys of Hard Hill plots.
Burn treatments are short rotation (S), long rotation (L), no-burn since 1954 (N) and unburned reference (R).
Fig 2.
Values for i) transect frequency (0–1), ii) map frequency (0–1), iii) median patch size (m2) and iv) median hummock height (cm) of Sphagnum for all plots (grazed and fenced) within the main experiment in 2015–16. Burn treatments are short rotation (S), long rotation (L) and no-burn (N). Treatments which do not share an x, y, z letter coding are significantly different (p < 0.05) according to Tukey HSD tests.

Results of split plot ANOVAs for Sphagnum-related variables (transformations in brackets) recorded in the main experiment plots (grazed and fenced S, L and N) in 2015–16.

Values for i) transect frequency (0–1), ii) map frequency (0–1), iii) median patch size (m2) and iv) median hummock height (cm) of Sphagnum for grazed plots within the main experiment, and reference plots in 2015–16. Burn treatments are short rotation (S), long rotation (L), no-burn (N) and reference (R). Treatments which do not share an x, y, z letter coding are significantly different (p < 0.05) according to Tukey HSD tests.

Results of ANOVAs for Sphagnum-related variables recorded in the 2015–16 survey in the grazed main experiment (S, L and N) and reference (R) plots.
Transformations of the dependent variables are noted in brackets.
Fig 4.
Boxplots showing Sphagnum % cover (transformed from domin scale values) in grazed and fenced plots within the main experiment in 1961 (data from 25 quadrats in each of 4 plots per treatment; n = 100).
Burn treatments are short rotation (S), long rotation (L) and no-burn (N). The horizontal line, box, whiskers, dots and ◊ indicate the median, upper and lower quartiles, minimum and maximum excluding outliers, outliers and mean respectively. Treatments sharing the letter x coding are not significantly different (p > 0.05) according to Tukey HSD tests.
Fig 5.
Boxplots showing Sphagnum cover (recorded on the domin scale and transformed to %) in reference (R) and grazed no-burn (N) plots (data from 5 quadrats in each of 4 plots per treatment; n = 20).
The horizontal line, box, whiskers, dots and ◊ indicate the median, upper and lower quartiles, minimum and maximum excluding outliers, outliers and mean respectively. Treatments which do not share an x, y, z letter coding are significantly different (p < 0.05).
