Vegetation development on the barrier islands of the Ola lagoon (the Sea of Okhotsk) in conditions of the rapidly increasing number of seabirds

Abstract

Colonies of slaty-backed gull (Larus schistisagus) are studied on the barrier islands of the Ola lagoon (the Sea of Okhotsk), whose coastline has undergone significant changes for the last 40 years. The abundance of birds has grown by a factor of 2.5 for 5 years and reached 7000 pairs in 2014. Five vegetation communities with the prevalence of herbaceous plants are described and schemed.
