Abstract

Kandungan karbon tersimpan terdapat pada permukaan tanah sebagai biomassa tumbuhan, sisa tumbuhan yang sudah mati (nekromasa), maupun dalam tanah sebagai bahan organik tanah. Tulisan ini memaparkan tentang  bagaimana kandungan karbon tersimpan pada hutan primer dan hutan sekunder. Cadangan karbon pada berbagai kelas penutupan lahan di hutan alam berkisar antara 7,5 – 264,70 ton C/ha. Pada hutan primer cadangan karbon berkisar 15,02 – 264,70 ton C/ha. Cadangan karbon terendah terdapat pada hutan bukit kapur dan tertinggi pada hutan alam primer dataran rendah dan dipterokarpa. Hutan alam sekunder  memiliki cadangan karbon berkisar 7,5 – 249,1 ton C/ha, dengan cadangan karbon terendah pada hutan bekas bakaran dan tertinggi pada hutan bekas tebangan. Cadangan karbon hutan alam primer lebih tinggi dari pada hutan alam sekunder yang disebabkan oleh keanekaragaman jenis tumbuhan pada hutan alam primer lebih tinggi dibandingkan dengan hutan sekunder sehingga pengembalian karbon organik ke dalam tanah berjalan dengan cepat dan penyimpanan biomassa hasil konversi karbon bertambah besar seiring dengan semakin banyaknya karbon yang diserap pohon tersebut.

Abstract

Birds play an important role in mangrove ecosystems because they help improve forests in natural ways such as flower pollination, and grain dispersal. This study was conducted to find out the types of birds, diversity, equality and dominance of bird species in the Karang Gading and Langkat Northeast Wildlife Sanctuaries. A method that combines the calculation point of IPA (Indices Ponctuele d'Abundance) with the transect line (line transect). Found 43 species of birds from 10 Orders and 22 families. The diversity index in the Karang Gading and Langkat Northeast Wildlife Sanctuary area has a value of 2.80 with a medium category. Furthermore, the equality index has a value of 0.81 with an uneven category. Then the dominant index of bird species in the area has an average category of non-dominant bird species. This value indicates that the Karang Gading Wildlife Sanctuary and Northeast langkat area supports as a bird habitat with the success of a type of bird in utilizing niches and being able to adapt to environmental conditions from all disturbances such as anthropogenic activities in the region.

Abstract

The Urticaceae family is herbaceous, semi-shrub, climbing (liana), small trees, and shrubs that have important ecological and economic roles. This research was conducted to determine the composition and structure, diversity, and utilization of Urticaceae family plants in the Forest of Bukum Village, Sibolangit District, Deli Serdang Regency, North Sumatra. This research is an exploratory survey using the quadratic method. The plots were purposive sampling as many as 10 plots measuring 10m x 10m. There are 25 species of plants in the Urticaceae family with 547 individuals. The most common type of plant found is Elatostema sessile JRForst. & G. Forst. Highest importance index on Elatostema sessile JRForst. & G. Forst. (INP 91,30%). The plant diversity index of the Urticaceae family is moderate with H' 2.64 which is included in the stable community.

Abstract

The family Araceae, the taro family, has a terrestrial habitus, for better or for worse, submerged or submerged in water. Araceae is also very abundant and diverse in wet tropical areas such as the Bukum Village Forest area. This study aims to determine the types of the Araceae family, the diversity index and the distribution pattern of the Araceae family in the Forest of Bukum Village, Sibolangit District, Deli Serdang Regency, North Sumatra which was carried out in December 2021 - February 2022. The method used was exploratory with the technique of making square plots. by purposive sampling on 2 transects, each of which has 8 plots of observations. The results of the study were 24 species from the Araceae family with the most common species being Schismatoglottis calyptrata (Roxb) with 157 individuals. There are at least 4 species of individuals, namely Aglaonema commutatum Schott, Aglaonema nebulosum N.E.Br., Homalomena rostrata Griff. and Syngonium podophyllum Schott by 2 individuals. The diversity index of transect I was 2.00 and transect II was 2.36. The diversity index data shows moderate environmental diversity, because the productivity is quite high, the ecosystem condition is balanced and the ecological pressure is moderate. The morisita index on transect I of 1.59 shows the pattern of distribution is moderate, this occurs due to uneven (uniform) abiotic conditions although in a narrow location. The morisita index on transect II of 0.98 indicates an even distribution pattern, due to individual competition which encourages the distribution of space evenly.
