Determination of Plant Densities [PDF]

open access: yesNature, 1948
E. J. MACHIN1 appears to be unaware of the extensive study by G. E. Blackman2 on the relation between plant density and percentage absence. In a theoretical appendix to this paper, I have pointed out that the most efficient size of quadrat corresponds to about 20 per cent absence, or a product of quadrat size and plant density of about 1·6 (the ...
