N.  aFrequency sampling in sagebrush-bunchgrass vegetation.h[electronic resource]  c1963  aAbstract: Appropriate quadrat sizes and efficient allocations of sampling units were determined for frequency sampling of the Artemisia arbuscula/Festuca idahoensis association in southeastern Oregon. The theoretical considerations and equations pertinent to these determinations were reviewed. A quadrat 6 to 10 inches square is appropriate for frequency sampling of the common species, and an allocation of 10 to 20 quadrats per transect attains optimum efficiency. Quadrats and transects were held synonymous with subplots and plots in the application of subsampling theory for the determination of efficient allocations. A sample of 15 transects, each including ten 9-inch quadrats, was convenient, appropriate, and efficient. This sampling structure is recommended for subsequent frequency sampling of sagebrush-bunchgrass vegetation.  aGrasslands  aSampling  aPastagem  aAmostragem de vegetacao  aFrequencia  aQuadrat size  aSagebrush bunchgrass1 aCONRAD, C.
