Invertebrate species in need of conservation in Primorye Territory, Russian Far East (for the regional Red Data Book update)
This work presents a new list of threatened invertebrates for the regional Red Data Book based on long-term biodiversity monitoring in Primorye Territory and a detailed consideration of the principles and criteria for compiling the Red Lists. The list includes 99 species, 45 of which are listed in the Red List of Russia published in 2020. These 45 species from Primorye Territory comprise 28.5 % of invertebrate species from the new Red List of Russian Federation. Regional invertebrates in need of protection are combined by terrestrial (62 species), freshwater (25 species) and marine (12 species) ecological groups in 28 orders and four phyla: annelids (2 species), nemerteans (1 species), mollusks (30 species) and arthropods (66 species). The number of rare species in these ecological groups adequately reflects the unique features of Primorye Territory’s nature.
