| Summary: | The fodder value of meadows used as hayfields and pastures decreases because of the growth of poisonous plants on them. Poisonous plants are those that cause serious poisoning in animals that consume them, and in some cases it leads to death of the animals. The toxicity is due to the con-tent of special reactive compounds in them. The research objective is to conduct a geobotanical sur-vey of the meadow on the territory of the Tinky-II reclamation site on the lands of the Ryazan Mesh-chera to determine the botanical composition of meadow grasses, to identify and determine the abundance of poisonous plants on it. The location of the meadow is near the village of Polkovo, Ryazan district, Ryazan region. The survey covered the area of 10,000 m2 in July 2019 during a prelim-inary reconnaissance survey of the territory along the working routes. The research methodology is generally acknowledged. As a result of the territory survey, it was established that the dominant plants are Elytrígia repens and Alopecurus pratensis, that occur frequently and have a high degree of abundance. As a result of studying the vegetation cover, the association Elytrígetum urtícetosum was distinguished in the examined area of the meadow. The plants grew with a continuous carpet and the soil cover was up to 100%. The total number of poisonous plants was 102 from 6 families. The most common poisonous plants are represented by the Apiaceae and Ranunculaceae families. The share of each poisonous component: Conium maculatum – 36%, Chaerophyllum temulum, Cicuta virosa – 29%, Oenanthe aquatica, Thalictrum aquilegiifolium – 15%, Caltha palustris, Anemone ranunculoides – 8%, Calla palustris, Pedicularis palustris pa riceprica, hydrachlecha – 12% each. Thus, the species composition of meadow grasses is depleted and there is little chance of poisoning of farm animals, since the presence of poisonous plants is insignificant, taking into account their negative impact on the animal’s body only at a certain dose and duration of exposure. |
