Distribution of sea buckthorn (Hippophae rhamnoides L.), an invasive species, in an Irish nature reserve and its relevance for birds.

Abstract

Sea Buckthorn (Hippophae rhamnoides L.) is a non-native and invasive species that was introduced to North Bull Island in Dublin Bay in the 1970s. Since then, outward spread by rhizome has taken place from the original plantings along the boundaries of the two golf courses in the island. Dispersal of seeds by birds, and potentially by humans, is likely to be responsible for the disjunct distribution of isolated plants elsewhere. Sea Buckthorn is now widely but thinly distributed throughout the island. Although it is a dense scrub with berry-like fruit, it is only utilised by a small number of bird species for feeding or nesting.
