Identifikasi Potensi Permudaan Alam Di Hutan Rawa Gambut Taman Hutan Raya Orang Kayo Hitam Provinsi Jambi Pasca Kebakaran Hutan
Abstract
Abstrak
Regenerasi dan restorasi hutan rawa gambut merupakan hal yang sulit terjadi secara alami. Restorasi ekosistem bukan hanya membuat tegakan baru tetapi juga harus berbasis keanekaragaman hayati lokal untuk membuat peluang berhasilnya menjadi lebih tinggi. Tujuan dari penelitian ini adalah mendapatkan data mengenai potensi permudaan alam dalam rangka regenerasi dan restorasi lahan gambut di Tahura Orang Kayo Hitam pasca kebakaran hutan. Penelitian ini dilaksanakan selama 7 bulan, yaitu dari Maret sampai Oktober 2019 di Tahura Orang Kayo Hitam, Herbarium Fakultas Kehutanan Universitas Jambi dan Laboratorium Silvikultur dan Manajemen Universitas Jambi. Metode yang digunakan adalah kombinasi transek dengan garis berpetak. Hasil penelitian menunjukkan bahwa terdapat 29 jenis anakan alam yang tergabung dalam 19 famili tumbuhan. Jenis yang paling dominan adalah arang-arang (Diospyros mangiayi) diikuti oleh meranti bunga (Shorea teijsmanniana) dengan Indeks Nilai Penting (INP) berturut-turut sebesar 20,10% dan 19,33%. Indeks kekayaan Margaleff D= 4,88, indeks keanekaragaman Shannon-Wiener H’= 2,96 dan indeks Evennes E= 0,88. Nilai dari semua indeks menunjukkan kondisi permudaan alam yang cukup baik di Tahura Orang Kayo Hitam. Hal ini diharapkan mampu menjadi pendorong dalam restorasi ekosistem yang berbasis jenis lokal untuk masa depan hutan rawa gambut.
Abstract
Regeneration and restoration of peat swamp forests is a difficult thing to happen naturally. Ecosystem regeneration and restoration not only create new stands but must also be based on local biodiversity to make the chances of success even higher. The purpose of this study is to obtain data and information about the potential of seedlings for the regeneration and restoration of peatlands in Tahura Orang Kayo Hitam after forest fires. This research was conducted for 7 months from March to October 2019 with locations in Orang Kayo Hitam Tahura, Herbarium of the Faculty of Forestry at the University of Jambi and the University of Jambi's Silviculture and Management Laboratory. The most dominant types are arang-arang (Diospyros mangiayi) followed by meranti bunga (Shorea teijsmanniana) with Important Value Index (INP) respectively of 20.10% and 19.33%. Margaleff's Wealth Index D= 4, 88. The Shannon-Wiener Diversity Index shows a value of H 'of 2.96 and the Index of Evennes indicates a value of E= 0.88. The values obtained from all of the measured indices indicate the condition of natural regeneration which is quite good in Tahura Orang Kayo Hitam. This is expected to lead to local species-based ecosystem restoration for the future of peat swamp forests.
