Tembawang, Landau Kodah Village, Sekadau Hilir District, Sekadau Regency, is a forest outside the area managed by indigenous peoples. Information regarding the type of composition and structure of the stands contained therein requires data collection. The purpose of the study was to obtain data on the potential of germplasm and the ability to regenerate tembawang stands. The survey method for data collection uses a combination of sampling techniques between paths and checkered lines. The result is the potential for germplasm, for trees (25 families, 48 species, and 197 individuals), poles (19 families, 33 species, and 90 individuals), saplings (20 families, 34 species, and 174 individuals), seedlings (21 families, 52 species, and 335 individuals). Well-regenerated species which are found in all growth strata, there are 14 species namely, Bridelia glauca, Lansium demesticum Var., Hevea braziliensis, Coelostegia boroneensis Becc., Elateriospermum topas BI, Horsfieldia carnosa Warb., Litseia prima, Tristania spp., Palaquium xanthachymum, Macaranga hypoleuca, Bouea macrophylla, Calophyllum lanigerum Miq., Artocarpus integer, dan Syzygium chlorantum Merr. The species diversity of trees strata ( = 1,63) and seedlings ( = 1,58) were categorized as moderate, for poles strata ( = 1,37) and saplings ( = 1.20) are categorized as low. The evenness of species for all growth strata (e = > 0.50) is high. The regeneration status of tembawang is sufficient/medium (fair), because number of seedlings (335 trees/ha) > number of saplings (90 trees/ha) < number of trees (197 trees/ha).Keywords: species diversity, tembawang, indigenous peoples,AbstrakTembawang Desa Landau Kodah Kecamatan Sekadau Hilir Kabupaten Sekadau, merupakan hutan di luar kawasan yang dikelola oleh masyarakat adat. Informasi mengenai komposisi jenis dan struktur tegakan yang ada di dalamnya perlu pendataan. Tujuan penelitian, guna mendapatkan data potensi plasma nutfah dan kemampuan beregenerasi tegakan tegakan tembawang. Metode survey pengambilan data menggunakan teknik sampling kombinasi antara cara jalur dan garis berpetak. Hasilnya didapatkan potensi plasma nutfah untuk pohon (25 family, 48 spesies, dan 197 individu), tiang (19 family, 33 spesies, dan 90 individu), pancang (20 family, 34 spesies, dan 174 individu), semai (21 family, 52 spesies, dan 335 individu). Spesies-spesies yang berregenerasi dengan baik dimana ditemukan pada semua strata pertumbuhan, ada 14 spesies yaitu Bridelia glauca, Lansium demesticum Var., Hevea braziliensis, Coelostegia boroneensis Becc., Elateriospermum topas BI, Horsfieldia carnosa Warb., Litseia prima, Tristania spp., Palaquium xanthachymum, Macaranga hypoleuca, Bouea macrophylla, Calophyllum lanigerum Miq., Artocarpus integer, dan Syzygium chlorantum Merr. Keanekaragaman spesies strata pohon ( = 1,63) dan semai ( = 1,58 ) dikatagorikan sedang, untuk strata tiang ( = 1,37 ) dan pancang ( = 1.20 ) dikatagorikan rendah. Kemerataan spesies untuk semua strata pertumbuhan (e = > 0,50)) tergolong tinggi. Status regenerasi tembawang cukup/sedang (fair) karena jumlah semai (335 pohon/ha) > jumlah pancang (90 pohon/ha) < jumlah pohon (197 pohon/ha)Kata kunci: keanekaragaman jenis, tembawang, masyarakat adat
