This study aims to obtain information about the succession levels of natural vegetation on excommunity gold mining in Monterado. The method of this research was survey method through vegetation analysis by double plot size 20 m x 20 m. Placement of plots dileberately based on the tailing period of excommunity gold mining which were : < 1 year, 2-3 years, 5-7 years, and > 10 years. The result showed that kinds of shrub found in all age level of excommunity gold mining area. The type of woody plants at the seedling found in all period of excommunity gold mining area, whereas sapling, pole and tree only found in excommunity gold mining at age level > 10 years. Based on the vegetation analysis, it showed that Ischaemum rugosum and Melastoma malabathricum L. dominanted at all age level of excommunity gold mining. Seedling in the excommunity gold mining at all age level were dominanted by Dillenia suffruticus. The index of species diversity showed that it was still low on excommunity gold mining in Monterado.Until the age of tailing > 10 years, succession was still in the level of competition, so it was concluded to be slow. To accelerate succession, revegetation, land restoration, and people awareness should be undertaken. PENDAHULUANKegiatan penambangan emas di dalam kawasan hutan merupakan salah satu gangguan terhadap hutan. Aktivitas penambangan emas dapat berdampak pada kondisi lingkungan baik secara fisik, kimia maupun biologi. Secara fisik dapat dilihat dari terbukanya lahan yang cukup luas dan berubah manjadi lahan tandus berwujud padang pasir berisi tailing. Secara kimiawi diketahui dari pencemaran air, tanah dan vegetasi akibat dari penggunaan zat yang berbahaya seperti merkuri. Secara biologi dapat dilihat dari hilangnya vegetasi dan asosiasi organisme.Seiring dengan berjalannya waktu, lahan bekas penambangan emas akan mengalami suksesi. Kondisi lahan yang
