Using Applied Research to Manage Russian Olives and Increase Avian Diversity

Jim Castle

Russian olive trees form dense thickets in riparian areas, crowding out native plants and excluding the birds that rely on them. Some birds, however, love to eat Russian olive fruits. Russian olives spread easily and are difficult to remove — what is the best way to reduce their effect on the environment? Through Jim’s work with the Army Corps of Engineers, they have discovered that a mosaic of habitats is a good approach. They showed increased bird diversity when they removed about half of the Russian olives in a way that created patches of native and non-native habitats.
