Preservation of natural forests at present is more urgent than ever. In the Municipal Budgetary Educational Institution "Leskhozskiy secondary education school" in the Arskiydistrict, in order to attract the attention of the students to the need of forests reproduction with the help of seeds, an environmental campaignon collection of pine cones "Harvest of the Forest" was held. The schoolchildren of 1-11 formsparticipated there. In total, 1848kg of cones were collected. Think about this number. It is rather small in terms of arithmetic: but how many thousands, millions of seeds in these kilograms! The schoolchildren have made a significant contribution to the creation of forests of the future. Leaders among the forms were 1 form (307 kg), 9 form (190 kg), 7 form (351 kg). It would be great to continue this kind and useful tradition of collecting cones in the future.
