Environmental Systems Research

Table 1 Mean (S.E) monthly leaf litterfall dry matter production and its Pearson correlation coefficient with monthly average rainfall at exclosures and grazing land in Kewet district, central dry lowland of Ethiopia

Land use	Litterfall dry matter (g m⁻²)	Pearson correlation coefficient (r)
Grazing land	8.94 ± 0.83^c	0.27^ns
Young exclosure	12.84 ± 0.99^bc	− 0.19^ns
Middle exclosure	13.57 ± 1.54^b	0.56^ns
Old exclosure	22.19 ± 1.45^a	− 0.43^ns
p-value	0.03
CV %	50.53

Mean ± S.E. with different letters within a column are significantly different (p < 0.05) (Tukey’s test HSD)
CV coefficient of variance
^ns Correlation is non-significant at the 0.05 level
