Keragaman dan komposisi jenis bibit untuk rehabilitasi hutan dan lahan (RHL) di Derah Aliran Sungai (DAS) Kapuas
Abstrak
Indonesia mempunyai lahan terdegradasi yang luas untuk direhabilitasi. Penelitian ini bertujuan untuk menganalisis keanekaragaman jenis dan komposisi bibit untuk rehabilitasi lahan di DAS Kapuas, alasan pemilihan jenis, dan lokasi penanaman bibit serta membandingkan komposisi jenis bibit untuk rehabilitasi lahan terdegradasi di DAS Kapuas dan DAS Serayu- Opak-Progo. Data bibit selama tiga tahun (2015-2016-2017) dikumpulkan melalui kuesioner kepada Balai Pengelola DAS Kapuas. Data dianalisis secara kuantitatif menggunakan perangkat lunak statistik yang disebut Past. Hasil penelitian menunjukkan bahwa kekayaan spesies bibit per tahun berkisar antara 15-25 dengan jumlah total spesies 34, terdiri dari 24 spesies asli dan 10 spesies introduksi. Indeks dominasi Simpson (D) sebesar 0,19-0,93, indeks keanekaragaman Simpson (1-D) 0,07-0,81, dan indeks keanekaragaman Shannon (H’) 0,22-1,97. Pemilihan spesies sebagian besar ditentukan oleh ketersediaannya yang tinggi dan sebagian besar bibit ditanam di kawasan hutan. Komposisi jenis bibit di DAS Kapuas mempunyai kemiripan yang rendah dengan DAS Serayu-Opak-Progo. Vegetasi yang dihasilkan akan mempunyai spesies yang cukup beragam.
