FIELD: examination of ground vegetation covers. SUBSTANCE: space photography is conducted with allowance for vegetation phases of plants. Areas anomalous by degree of spectral brightness are exposed. Ground exploration are carried out on them. Evaluation of conditions of vegetation objects and outlining of territories are conducted by evaluation results. Cores of wood are taken from model trees with their referencing to locality and to photographs during examination. Values of optical density of model trees on photographs are established. Evaluation of state of model trees is accomplished by value of wood growth. EFFECT: enhanced efficiency of procedure. 1 tbl
