Vegetation Development on the Barrier Islands of the Ola Lagoon (the Sea of Okhotsk) in the Conditions of Rapidly Increasing Number of Seabirds
The colonies of slaty-backed gull (<i>Larus schistisagus</i>) and vegetation development were studied on the barrier islands of the Ola lagoon (the Sea of Okhotsk), which coastline has underwent great changes over the last 40 years. The number of the birds increased 2.6 times in the last 5 years, and in 2014 reached 7 thousand pairs.
