Urban areas often contain sizeable pockets of degraded lamg such as inactive landfill~ that could be reclaimed as wildlife habitat and as connecting links to enhance remnant natural area£ In the northeastern U.S., many such lands fail to undergo natural succession to woodlaru~ instead retaining a weedy, herbaceous cover for many year~ We hypothesize that seed dispersal is a limiting factor, and that a form of secondary succession could be stimulated by introducing clusters of trees and shrubs to attract avian seed dlsperser~ As a direct tesg we censused a 1.5-ha experimental plantation on the Fresh Kills Landfill (Staten Island, New York) one year after installation, in search of evidence that the plantation was spreading or increasing in dimity. The 17planted specie~ many from coastal scrub forests native to this region, were surviving well but contributed almost no seedlings to the area~ in part because only 2096 of the installed trees or shrubs were reprodactiv~ Of the 1079 woody seedlings foun~ 95 96 came from sources outside the plantatior~, most ( 71 ~6 ) were from fleshy-fruttea~ bird-dispersed plants from nearby woodland fringes. Although the restoration planting itself had not begun to produce seedling~ it did function as a site for attracting dlsperser~ who enriched the young community with 20 new specie~ One-fourth of ail new recruits were from nine additional wind-dispersed specie~ Locations with a high ratio of trees to shrubs had proportionately more recruit& indicating that plant size contributed to disperser attractiorL The density of new recruits of each species was dependent on distance from the nearest potential seed source. Introducing native species with the capacity to attract avian dispersers may be the key to success of many restoration program.~ Restablecimiento del bosque en una clausura: Rdpida adici6n de especies por aves dispersoras Resumen: Areas urbanas usualmente contienen nucleos aislados de tama~o conslderabl~ de tierras degradadas, como vertederos pt~blicos inactivos que pueden ser reclamados como hdbitat para vlda silvestr~ y como vlnculos de conecci6n para ampllar dreas naturales remanente~ En el Noreste de Estados Unidos muchas de estas tierras fracasan en el proceso natural de sucesiOn hacla bosque~ en vez retienen pot muchos a~os una cubierta h~qadcea de maleza£ Nuestra hip6tesis es que la dispersi6n de las semillas es un factor limitante.
