Watershed (DAS) which is included in the category that must be restored is the Gunung Batu watershed in Tebing Siring Pelaihari Village. High land clearing for both the mining sector and oil palm plantations makes the watershed area in South Kalimantan very vulnerable to flooding so that it clearly has a major impact on increasing flood vulnerability, coupled with the number of land fires during the dry season so that the rainwater infiltration process is no longer running properly (Aulina et al. 2017). Watershed Rehabilitation Land in Gunung Batu Village was restored by replanting various types of forestry plants, one of which is eucalyptus (Melaleuca leucadendra). Eucalyptus was chosen as a revegetation plant because it is able to live in dry soil and does not have specific growing conditions. In order to know the state and condition of eucalyptus plants, data is needed as raw material for analysis. There is no record or data on the health of eucalyptus oil for the rehabilitation of the Gunung Batu watershed, so the authors are interested in conducting research on the health of the eucalyptus oil plant on the land. Based on the results of the study, the percentage of live eucalyptus plants in the rehabilitation area of the Gunung Batu watershed was 97.73% with an average height of 3.15 m and a diameter of 5.84 cm, the most damage was in the leaves. However, in general, eucalyptus plants in the Gunung Batu watershed, Tebing Siring Pelaihari Village, were healthy with an INK of 1.00.Daerah Aliran Sungai (DAS) yang termasuk kategori harus dipulihkan adalah DAS Gunung Batu Desa Tebing Siring Pelaihari. Pembukaan lahan yang tinggi baik untuk sektor pertambangan maupun perkebunan kelapa sawit membuat wilayah DAS di Kalimanatan Selatan sangat rentan banjir sehingga sangat jelas berdampak besar terhadap meningkatnya kerawanan banjir, ditambah dengan banyaknya kebakaran lahan sepanjang musim kemarau sehingga proses infiltrasi air hujan tidak lagi berjalan secara baik (Aulina et al. 2017). Lahan Rehabilitasi DAS Desa Gunung Batu dipulihkan dengan cara menanam kembali berbagai jenis tanaman kehutanan, satu diantaranya adalah jenis kayu putih (Melaleuca leucadendra). Tanaman kayu putih dipilih sebagai tanaman revegetasi karena mampu hidup di tanah yang kering serta tidak memiliki syarat tumbuh yang spesifik. Agar dapat mengetahui keadaan dan kondisi tanaman kayu putih maka diperlukan data sebagai bahan mentah analisis.  Pencatatan atau data kesehatan tanaman minyak kayu putih untuk lahan rehabilitasi DAS Gunung Batu sampai saat ini belum ada, sehingga penulis tertarik untuk melakukan penelitian mengenai kesehatan tanaman minyak kayu putih dilahan tersebut. Berdasarkan hasil penelitian persentase hidup tanaman kayu putih pada lahan rehabilitasi DAS Gunung Batu 97.73% dengan rerata tinggi 3,15 m dan diameter 5,84 cm, kerusakan paling banyak di bagian daun.  Namun secara umum tanaman kayu putih di DAS Gunung Batu Desa Tebing Siring Pelaihari adalah sehat dengan INK 1,00

The presence of potentially invasive plant species in the midst of native South Kalimantan pamah plants can inadvertently be carried away by tourists and several types of fauna such as birds and squirrels. This study aims to analyze the diversity of invasive plant species, and their dominance in the plant community in Tanjung Puri Tabalong Botanical Gardens, South Kalimantan. This research was conducted at the Tanjung Puri Botanical Gardens which is administratively located in Kasiau Village, Murung Pudak District. Points A.1 and A.2; measuring plots on rubber plantation vegetation, Points B.1 and B.2; measuring plots on shrubby vegetation – grasslands and Points C.1 and C.2; plots of forest vegetation. Plant Composition (Important Value Index) The formula or equation to calculate the INP. The plant species identified in Tanjung Puri Tabalong Botanical Gardens were 57 species from 32 families. There were 5 species from 5 invasive plant families with the highest importance index and dominance index found at the three research sites, namely Acacia mangium, Vitex pinnata L, Eupatorium inulifolium, Imperata cylindrica, and Melastoma malabathricum.

Ulin is a type of woody trees with a slow growth process that can be caused by two factors, namely internal factors (seed sources) and environmental factors (growth sites). Therefore the ulins from two different places (Kalsel and Kaltim) were tested in order to compare their growth. This was done by observing the growth of height and diameter of the stem. The method used was a quantitative method using the Independent-Sample T Test in the Staistical Package for Social Sciences to compare the growth of the two ulins. The results obtained at an average plant height showed that ulin Kaltim had better growth of 3.07 m than that of South Kalimantan which was 2.15 m. Furthermore, the diameter of ulin derived from Kaltim was 13.12 mm while that of South Kalimantan was 9.63 mm.Keywords: Ulin; Growth; Kaltim; Kalsel
