Indonesia is known as one of the countries with the largest biodiversity in the world (megadiversity) and is the center of world biodiversity (megacenter of biodiversity). Rhizanthes loweii has a geographic distribution from Sumatra, Peninsular Malaysia, and Kalimantan. In Sumatra this species has been recorded to be found in Mount Leuser, Sibolangit, Mount Dempo, South Sumatra, Penanggungan, Lampung and Bengkulu. KSNP as one of the largest conservation areas in Indonesia has a very high and diverse potential for natural resources and environmental services. TNKS also has various data objects of natural tourist attractions that have the potential to be developed, including mountains, hills, lakes and waterfalls. This research was conducted in the Kerici Seblat National Park (TNKS) Resort Sungai Lambai. The method that will be used in collecting data in this research is the path method and the determination of the observation plot is carried out by purposive sampling. Each 1 ha measuring plot counted the number of individuals with Rhizanthes loweii buds/flowers. This Important Value Index (INP) is used to determine the species composition and dominance of a species in a stand. Sungai Lambai Resort is located in Nagari Lubuak Gadang Selatan, Sangir District, South Solok Regency, West Sumatra. Nagari Lubuak Gadang Selatan is divided into five jorongs, namely, Jorong Pincuran Tujuh, Jorong Sungai Lambai, Jorong Karang Putiah, Jorong Ayia Manyuruak and Jorong Liki. The vegetation around Rhizanthes loweii contained in the research plot amounted to 32 species with seedling, sapling, pole and tree levels. The soil in this research location is generally alkaline soil. The type of clay soil is dusty, has a smooth texture, and is blackish brown in color. Habitat characteristics and distribution of Rhizanthes loweii in Kerinci Seblat National Park lives on dusty clay soil with blackish brown color and average soil pH of 7.1 (neutral). The average temperature is 23.7⁰ C and the average humidity is 80%.Keywords: TNKS, Habitat, Distribution, Rhizanthes loweii. (Becc)

The need for data and information is an essential issue in sustainable mangrove management. The availability of data from authorized institutions is essential considering the reliability and consistency of the data, both to process techniques and data availability. This study used national mangrove and landcover data produced by the Ministry of Environment and Forestry through online services. 11 data series (2000 – 2019) obtained through the Representational State Transfer (REST) Application Programming Interface (API) service. Application of spatial analysis of vector data through geoprocessing tools and attribute data management to determine the distribution and changes in mangrove cover and the factors that trigger changes. Estimated data indicate a 13.4% decline in mangroves in Riau Province, with an average decline of 2,495.9 hectares/year. Over 98% of mangrove changes into other functions are caused by human behavior towards mangroves; we need a genuine attitude to preserve the mangroves of Riau Province for the future

Bukit Suligi Protection Forest was a protected forest in Riau area which is a stretch of wet tropical forest. The forest land cover of this area continues to decline due to forest fires and forest area conversion. These problems will affected changes in the Bukit Suligi Protection Forest cover. Efforts to find out the change in cover of Bukit Suligi Protected Forest Area land was monitored to see changes in land cover in the area. The purpose of research was changes detection the Bukit Suligi Protection Forest cover in Kampar District through interpretation of Landsat imageries 1997, 2007 and 2017. Identify factors that cause changes in the cover of Bukit Suligi Protection Forest. This research analyzed land cover changes and interviews. Based on the results of interpretation of Landsat imageries in 1997, 2007 and 2017, land cover changes that occurred in the period 1997 - 2017 reached 4447.62 ha or 76.76% of the total area. If described in the period 1997 - 2007 land cover changes amounted to 2920.32 ha or 50.40% of the total area, these changes continue to increase until the period 2007 - 2017 land cover changes of 3627 ha or 62.60% of the total area. Factors that influence changes in the cover area of Bukit Suligi Protection Forest are natural factors and human factors. The human factor consists of population growth and government policies, namely the lack of supervision by the government in the forestry sector, specifically the management of the Bukit Suligi Protected Forest area.
