Table 3: Superficial characteristics of the nesting sites of L. malachurum sampled in 2008. Measures were taken at 3 plots of $1\hspace{0.17em}m\times 1\hspace{0.17em}m$ at each site. Except for soil hardness, which was taken 3 times at each plot (9 measures per site), all the other variables have $n=3$, so that statistical comparisons were not possible.
