“…Though there are some dominant species in Sironga wetland for example Scirpus debilis with 10,998 individuals and Ipomoea acquatica with 9802 individuals, the diversity is still low. The presence of several species in a disturbed environment is because the species have the ability to live and adapt to the environmental changes [12]. The main causes of biodiversity loss are land use and land cover changes which may lead to the dominance of new invasive species at the expense of native plant species [13] [14].…”

Brick making is one of the major small-scale industries in Sironga which has been expanding due to the growing demand for urban expansion. Due to the increasing population pressure, brick-making is competing for the wetland resources. Sironga wetland is threatened with serious degradation and probable loss of plant diversity. Conversion of this wetland for economic uses such as brick making has resulted in its loss. The objective of the study was to assess the effects of brick making on plant diversity in Sironga wetland. Nyamira County, Kenya. A one metre by one metre quadrat frame was laid down and perpendicularly recorded the percent cover for each species found inside the quadrant plus the percentage area covered by the bare ground litter. From each transect lines "diagonally" detailed vegetation under study was then done. The plant species were recorded and classified into three life-forms; herbs, sedges and grasses. The study revealed that grasses had the highest diversity H = 1.144. Diversity for herbs was H = 0.987 and H = 0.899 for reeds respectively. The study concluded that brick-making activities affected the plant diversity in Sironga wetland. This may be attributed partly to the limited information and awareness campaigns to the surrounding communities on the values and benefits of wetland ecosystem services and the lack of alternative livelihood sources. The study recommends that alternative livelihoods are provided and awareness campaigns on the values and benefits of wetlands to the residents are done by the relevant agencies.

Gunung Leuser National Park (NP) is the biggest NP in North Sumatra. Though very few plant ecological studies were conducted there. Most studies in Gunung Leuser NP are related with protected animals, such as Sumatran Tiger, Elephant or Orang Utan. Thus, the aim of this preliminary study is to understand the plant structure and composition in the tropical forest of Gunung Leuser National Park. A 0.5-ha plot was established near Gua Kambing, Tangkahan area in November 2015. All tree species bigger than 15 cm girth were recorded, measured, and identified. The dominant species were from Dipterocarpaceae, followed by Myrtaceae and Achariaceae. The total number of trees was 693 trees or 1,386 trees/ha with the total Basal area was 42.9m2/ha and the biggest diameter was 147cm. The results from diversity index analysis ((H’=4.43; D=0.97; α=75) confirm that the forest area had a relatively high diversity, with Agrostistachis sessilifolia dominates the understory layer. The Gua Kambing area had relatively high plant diversity, less disturbance, and bigger trees than other studied areas in tropical Indonesian forests in Sumatra.
