[email protected] Abstract The natural monument “Gray heron colony” is a specially protected area of about 100 ha with the largest colony of gray herons registered in Tatarstan Republic (Russia). The territory of the natural monument is closed to visitors. Here, we have studied the flora of the higher vascular plants of the area adjacent to the “Gray heron colony”, which is characterized by similar landscape and environmental conditions. Two main methods to identify plant species were used: fixed sites and a route method, for which a route network covering all the main biotopes of the studied area was laid. The structure of the flora was studied by analyzing systematic, geographic, biomorphological, and biocenotic compositions. The identified spectrum of the leading families (Asteraceae, Fabaceae, Rosaceae, Caryophyllaceae, Poaceae, Scrophulariaceae, Apiaceae, Ranunculaceae, Lamiaceae, and Cyperaceae), was typical for the Holarctic floristic kingdom. The spectrum of life forms found (according to Raunkiær and Serebryakov) was generally characteristic to the temperate zone: more than half of the species (57.5%) were represented by hemicryptophytes (according to Raunkiær); 67% of the species were perennials (according to Serebryakov). By biotopic localization, most species were forest and forest edge plants (31.4%). The geographical analysis has shown that most species of flora have a Euro-Asian type of distribution. Among identified species, two are listed in the Red Book of Tatarstan - Daphne mezereum L.
