  abstract = {{P}remise {R}arity is a complex and central concept in ecology and conservation biology. {Y}et, it is still poorly understood why some species are rare and others common. {H}ere, we aimed to understand the drivers of species rarity patterns in woody plant communities. {M}ethods {W}e analyzed the local abundance and landscape frequency of 121 woody plant species across 238 plots on {A}merican {S}amoa and {H}awaiian islands. {W}e first assessed whether taxonomy, life form (shrub, small tree, large tree), and dispersal syndrome (dispersed by animals or by other means) are associated with the rarity of species. {W}e then analyzed phylogenetic patterns in plant rarity and tested whether rarity patterns are associated with species evolutionary distinctiveness and the number of species within genera and families. {R}esults {L}arge trees were less abundant but more frequent than shrub species. {A}nimal-dispersed species tended to be less abundant than species dispersed by other means, while species frequency was not associated with dispersal syndromes. {R}elative frequency in {H}awai ' i exhibited a more robust phylogenetic signal than did abundance. {B}oth evolutionary distinctiveness and taxa species richness were significantly associated with the frequency of shrub species in {H}awai ' i. {C}onclusions {L}ife form appears consistently associated with the rarity of species. {H}igh diversification rate is probably a key factor explaining landscape-scale rarity of native species on isolated archipelagos like {H}awai ' i. {A}t the landscape scale, rarity appears to be inversely associated with evolutionary distinctiveness, but at the local scale, species abundance may be not associated with evolutionary distinctiveness.},
