“…There are perennial and annual plants grow in tropical rainforest (Du Rietz, 1931). Then, plant life-forms in tropical rainforest are found such as trees, shrubs, herbs and vines (Arbainsyah, de Iongh, Kustiawan, & de Snoo, 2014). Those can be distinguished based on stories or layer in tropical rainforest (Swaine, Whitmore, & Swaine, 1988).…”

Papua has so many wide lowland areas that cover high diversity in plant from lifeforms. In contrast, there is a lack of information concerning species diversity. The objectives of the research were to describe species of plant life-forms and to analyze conspecific associations between small individuals and large individuals in natural tropical rainforest, south Papua. Then, 46 nested plots were placed systematically in natural tropical rainforest of Boven Digoel Regency, Papua. Density, frequency, dominance and importance value index (IVI) were analyzed to describe plant diversity, while detrended correspondence analysis (DCA) was to describe conspecific association between small individuals and large individuals. Results found 2040 individuals in this forest consisting 194 plant species. Those are from pteridophytes, angiosperms and gymnosperms. The plant life-forms are herbs, orchids, palms, pandans, shrubs, rattans, vines and trees in which of the plant life-forms, trees are the most abundant according to number of species. In the dominant plant species, two types of conspecific association occurred between small individuals and large individuals. Analysis of DCA revealed that there are large plant species grow along with their small individuals. Another type is that small individuals grow far from their large individuals.

“…Furthermore, the importance value (IV; Eq. 3) of each species was calculated as the sum of its relative density (RD), relative dominance (Rd) and relative frequency (RF) where density (D) is the number of individuals per hectare, dominance (d) is the basal area (BA) of each species per hectare and frequency (F) is the number of plots where a species is present divided by the total number of plots (de Iongh Arbainsyah et al 2014;Mueller-Dombois and Ellenberg 1974).…”

“…Deforestasi dan degradasi hutan tropis yang ditimbulkan oleh kegiatan manusia berpotensi menimbulkan kepunahan keanekaragaman hayati (Dent and Wright, 2009;Laurance, Sayer and Cassman, 2014;Pryde et al, 2015). Sebagaimana Arbainsyah et al (2014) menemukan kelimpahan dan komposisi jenis pohon di hutan primer lebih tinggi dibandingkan hutan sekunder bekas tebangan. Chazdon et al (2009) menambahkan hutan sekunder dapat digunakan sebagai tempat untuk mengkonservasi keanekaragaman hayati.…”

“…Indeks kelimpahan pada semua tingkat pertumbuhan menunjukan nilai dalam kisaran 0,78 -0,95 yang berarti pola penyebaran individu tiap jenis hampir merata (Arini dan Wahyuni, 2016). Selain itu pancang memiliki indeks kelimpahan tertinggi sebesar 0,95 yang nilainya sama dengan indeks kelimpahan pancang di hutan alam pada penelitian Arbainsyah et al, (2014). Lebih lanjut penelitian tersebut mengindikasikan bahwa baik di hutan alam maupun hutan bekas tebangan, keragaman dan kelimpahanvegetasi tingkat semai dan pancang lebih tinggi dibandingkan pohon.…”

ABSTRAKHutan sekunder di Indonesia yang mencakup 24,2 % luas daratan Indonesia sebagian besar merupakan bekas pengusahaan hutan. Wacana pengelolaan kawasan hutan ke dalam Kesatuan Pengelolaan Hutan (KPH) sebagai unit pengelolaan hutan terkecil telah ditetapkan, termasuk pada area hutan sekunder bekas pengusahaan hutan. Pemahaman tentang vegetasi hutan sekunder bermanfaat dalam menentukan arah pengelolaannya di masa depan. Penelitian ini bertujuan untuk menganalisis komposisi, keragaman dan struktur pohon hutan sekunder bekas pengusahaan hutan di Nunuka Bolaang Mongondow Utara, Sulawesi Utara. Pengumpulan data berupa jumlah dan nama jenis pohon dilakukan dalam plot ukur 20 m x 20 m sejumlah 30 buah. Penelitian dilaksanakan pada bulan Nopember 2014. Tercatat sebanyak 84 jenis pohon di dalam plot pengukuran. Perhitungan Indeks Nilai Penting (INP) menunjukkan jenis pionir yaitu Anthocephalus macrophyllus mendominasi tingkat pertumbuhan pohon. Sementara itu tingkat tiang dan pancang didominasi oleh satu jenis yaitu Eugenia sp. Indeks Shannon-Wiener menunjukkan keragaman vegetasi termasuk rendah dan sedang. Sementara itu kelimpahan jenis pada tingkat pohon, tiang dan pancang termasuk hampir merata. Kerapatan vegetasi pada seluruh tingkat pertumbuhan sebesar 485,83 individu pohon/ hektar, rata-rata bidang dasar sebesar 35,15 m 2 /hektar. Struktur tegakan berdasarkan grafik kelas diameter tidak menyerupai huruf J terbalik sebagaimana sebaran diameter pohon di hutan alam primer. Namun struktur tegakan berdasarkan INP pada tingkat pohon dan pancang justru menyerupai huruf J terbalik. Kata kunci: komposisi jenis, struktur, hutan sekunder, Bolaang Mongondow Utara ABSTRACT
