Boyer, K.E., & Zedler, J.B. 1996 Damage to cordgrass by scale insects in a constructed salt marsh: effects of nitrogen additions.. Estuaries 19: 1-12.

Notes: Because tall cordgrass (Spartina foliosa) is needed for nesting by the endangered light-footed clapper rail, managers of constructed salt marshes in southern California are proposing large-scale nitrogen fertilization to improve cordgrass growth; this study examines how this process would affect an existing infestation of Haliaspis spartina and the degree of damage this species causes; effects of timing and duration of fertilization on Haliaspis; timing of Haliaspis dispersal; results show that fertilization did not increase Haliaspis population.
