Experimental studies on variations in the reflectivity of coniferous and deciduous woody vegetation in the spectral range of 0.4-2.4 microns were carried out, depending on the conditions for obtaining samples. It is shown that for deciduous trees, variations in measurement data caused by the fact that samples were taken from different trees, different sides of the crown of one tree, from the shady and sunny sides of the crown, from branches located at different heights are small. At the same time, the use of averaging over 10-15 different samples of leaves taken from different trees (of the same species) makes these variations insignificant. For coniferous trees, variations in measurement data, even for needle samples from the same tree, can be significant.
