This research consists of two independent variables, the disaster knowledge and environmental culture, and a dependent variable of disaster preparedness behaviour. The objective is to determine the relationship between disaster knowledge and environmental culture with disaster preparedness behaviour, as well as the relationship between both of the together with disaster preparedness behaviour. The study was conducted through 166 students of three senior high schools in the District of West Karawang, West Java, which taken by proportional random sampling. The method of survey was employed in this study and the data analyzed by statistical test of correlation and simple linier regression as well as multiple linear correlation and regression, which was conducted at significance level of α = 0.01 and α = 0.05. Based on the results, it was found that there was a positive and significant relationship between disaster knowledge and disaster preparedness behaviour with a correlation coefficient value of ry1 = 0.22 and a coefficient of determination value of (r2) = 0.049. There is a positive and significant relationship between environmental culture and disaster preparedness behaviour with a correlation coefficient value of ry2 = 0.25 and a coefficient of determination value of (r2) = 0.064. There is a positive and significant relationship between disaster knowledge and environmental culture together with disaster preparedness behaviour with a correlation coefficient value of ry12 = 0.32 and a coefficient of determination value of (r2) = 0.097. Thus, it can be concluded that student’s disaster preparedness behaviour can be improved through either disaster knowledge and environmental culture.Penelitian ini terdiri atas dua variabel bebas, pengetahuan kebencanaan dan budaya lingkungan, serta satu variabel terikat yaitu perilaku siaga bencana. Tujuannya untuk mengetahui hubungan antara pengetahuan kebencanaan, budaya lingkungan dengan perilaku siaga bencana, serta hubungan keduanya secara bersama-sama dengan perilaku siaga bencana. Penelitian dilaksanakan melalui 166 siswa di tiga sekolah menengah atas, Kecamatan Karawang Barat, yang diambil secara proporsional random sampling. Metode survey digunakan dan data dianalisis dengan uji statistik korelasi dan regresi sederhana serta korelasi dan regresi linear ganda, dilakukan pada taraf signifikansi α = 0,01 dan α = 0,05. Hasil menunjukkan bahwa terdapat hubungan positif dan signifikan antara pengetahuan kebencanaan dengan perilaku siaga bencana dengan nilai koefisien korelasi ry1 = 0,22 dan koefisien determinasi (r2) = 0,049. Terdapat hubungan positif dan signifikan antara budaya lingkungan dengan perilaku siaga bencana dengan nilai koefisien korelasi ry2 = 0,25dan koefisien determinasi (r2) = 0,064. Terdapat hubungan positif dan signifikan antara pengetahuan kebencanaan dan budaya lingkungan secara bersama-sama dengan perilaku siaga bencana, dengan nilai koefisien korelasi ry12 = 0,32 dan koefisien determinasi (r2) = 0,097. Jadi, dapat disimpulkan bahwa perilaku siaga bencana siswa dapat ditingkatkan melalui pengetahuan kebencanaan dan budaya lingkungan.

With this issue, the Indonesia Journal of Applied Environmental Studies (InJAST) enters its second year, having been first published in April 2020 just as the Covid-19 pandemic was spreading globally. In the first two issues, InJAST published 13 articles, which were the results of research and ideas from academia, researchers from the Indonesian Institute of Sciences (LIPI) and members of conservation NGOs. Within its first year, the InJAST website has been visited by around 1,500 visitors from 50+ countries. Although the majority were from Indonesia, 30% were from across Europe, Asia, the Americas, and Africa, and included the USA, UK, Australia, and India.One of InJAST's missions is to provide a vehicle for academia (students and lecturers), members of environmental NGOs, and young researchers, particularly from Indonesia, who are just starting to publish their ideas, literature reviews and research findings or articles in scientific journals. InJAST was also developed to accommodate scientific papers related to broader environmental topics, but as yet, most articles have focused on plant/wildlife ecology, nature conservation, and forest restoration (61%). Others were the result of the studies on environmental education (8%) and on the UN Sustainable Development Goals (SDGs) and other environmental issues (31%).As we start the third decade of the 21st century, the environmental challenges we face are ever more complex and demanding. The UN’s global action plan for the next 10 years set out in the "UN's 2030 Agenda for Sustainable Development", puts forward special measures to achieve a world that is fairer, more prosperous, and more respectful of the environment. The main global environmental challenges that, according to the UN, must be resolved in this decade, are climate change mitigation and adaptation, pollution problems and their effects on health, protecting oceans, the energy transitions and renewables, a sustainable food model, protecting biodiversity, sustainable urban development and mobility, hydric stress and water scarcity, extreme meteorological phenomena, and overpopulation and waste management. As academics, environmental researchers, and members of environmental NGOs, we can and should support the UN agenda by seeking the solutions to these major global environmental problems that affect all of us. We do this by carrying out relevant research and, just as importantly, publishing them in scientific journals so that we can disseminate our findings as widely as possible and suggested interventions can be trialed and then implemented on the ground.This new issue of InJAST contains several papers focusing on plant ecology, endangered species conservation, and forest restoration, all of which are closely related to one of the main global problems identified by the UN, namely protecting biodiversity. Another paper analyses determinants and typology of hydrometeorological disasters that may relate to the problem of extreme meteorological phenomena. Strong pro-environmental legislation and government regulations are very important in implementing existing environmental policies, and environmental awareness and responsibility are also important to assess whether people are willing to participate in addressing global environmental problems at the local level. This is explored in two other papers in this issue of InJAST.We reflect further that we are in a hugely different place from where we were at the start of 2020. The Covid pandemic, obviously a global tragedy, has changed many people’s behavioral patterns and our subsequent impact of nature and the environment. It seems to have in many ways heightened people's awareness of nature and environmental issues, and the relationships between unsustainable production and consumption and the nature and climate change crises. A plethora of new research is emerging on these interdisciplinary questions and we look forward to submissions tackling these questions in future editions of InJAST.Finally, as Editors-in-Chief, we have been working hard to improve and expand our peer review community, as well as the processes of online submission, reviewing and publishing. We are delighted to be presenting Volume 2 No 1 of InJAST and we encourage our colleagues from all sectors to submit their papers for the next issue.

Promoting interdisciplinary approaches to solving the complexity of environmental problems in Indonesia problems in Indonesia Kathryn A. Monk

As an ecologist, I believe we are now seeing the maturing of what we could call the Age of Ecology. An Age in which we finally develop that coherent and essential mainstream narrative for our future; one in which we tackle the interdependencies of nature loss, the climate emergency, and unsustainable production and consumption.The challenge has always been to recognise that the world is our bank account, and we live sustainably only by using its interest, not digging into our capital. If we do withdraw more capital, we must then find ways of investing more, to increase our capital. You can hear this language finally gaining much more traction today as politicians, managers and the public use the phrases natural and social capital, as well as the financial and manufactured capital, and recognise our dependencies on the natural environment.As such, I fully support the holistic, interdisciplinary sentiments and recommendations of Purwanto et al. (2020) in their introduction to the first issue of the Indonesian Journal of Applied Environmental Studies (InJAST). I have promoted interdisciplinary approaches to solving complex environmental problems throughout my career and worked with other academics and practitioners to support the realisation of the societal and economic impact of their research. We have increasingly recognised research impact institutionally and financially, but one main weakness persists and that is the availability of academic journals for publishing such interdisciplinary work. This journal can offer such a space for researchers and encourage the recognition and promotion of evidence to policy and practice communications. Most of all, this journal can foster the culture and confidence to ask the right questions to support the development of evidence-based decision making in policy and operational activities. I have spent a lot of time working with researchers who are doing excellent research but not asking the best questions to help improve management and utilisation of natural resources. Providing a forum in which students and early career researchers can confidently explore the rough answers to the right questions rather than the precise answers to the wrong questions, to paraphrase John Tukey (1915–2000), would be a wonderful role for InJAST.I am delighted to be asked to share my environmental experiences and perspectives in this guest editorial for the second issue of InJAST, reflecting for me a long association with Indonesia and Indonesian environmental managers, conservationists and foresters. I have worked around the world, especially in the tropics, firstly as part of scientific expeditions and then leading increasingly complex research and development programmes and institutions. Since returning to the UK, I have been involved in enhancing the quality and impact of scientific and interdisciplinary research and supporting the application and institutionalisation of the ecosystem approach and ecosystem services assessments. Here, I will focus on three major tropical environmental management programmes, two in Indonesia and one in Guyana, South America.These were complemented by subsequent involvement in the UK Government’s environmental management system. All reflect the evolution of environmental management and the emergence of the ecosystem approach, now being institutionalised slowly but surely around the world.

INTRODUCTION We know that there is only one earth, there are many different worlds. Different worldviews do not only have significant political and socio-economic repercussions but they also determine the way in which people perceive and interact with nature, thus forming their specific culture. Natural ecosystems cannot be understood, conserved and managed without recognizing the human culture that shape them, since biological and cultural diversities are mutually reinforcing and interdependent. Together, cultural diversity and biological diversity hold the key to ensuring resilience in both social and ecological systems (Erdelen, 2003). Through the environmental sciences and cultural activities, in promoting awareness and understanding of the relationships between biological and cultural diversity as a key basis for sustainable development.Beside has high biological diversity Indonesia also possesses high cultural diversity. It doesn’t marvel that Indonesia is the world’s largest archipelago, containing more than seventeen thousand island extending in an east-west direction for five thousand two hundred kilometers across the Sunda and Sahul continent shelves. The archipelago exhibits rich biodiversity that is unequalled in Asia (McNelly et al.,1990). Indonesia’s territory cover 7.7 million square kilometer, of which approximately 5.8 million square kilometers (75.3 %) is comprised of marine and coastal waters. Indonesia is located between two of Earth’s biogeographic regions: Indo-Malaya and Oceania. The Indo-Malaya region to the west includes Sumatra, Kalimantan, Java, and Bali, and the Oceanic region to the east includes Sulawesi, Moluccas, the eastern Sunda Islands, and West Papua. The vegetation types to the east and the west of the Wallace line are divided by a biogeographical boundary that extends from north to south along the Sunda Shelf. The natural vegetation on the shelf it self is comprised principally of the Malesian type, dominated by the commercially important Dipterocarpaceae. Vegetation to the east has greater affinities with Oceanic Austro-Pacific zone and is dominated by mixed tropical hardwood species. Deciduous monsoon forest occurs in seasonally dry areas, particularly in the southern and eastern islands such as the Lesser Sunda and the southern part of Papua. The outer islands of Sumatra, Kalimantan, Sulawesi, Moluccas, and Papua comprise approximately 10 % of the world’s tropical rainforest. Indonesia has more tropical forest than any other single Africa or Asia country, and is second only to Brazil in terms of tropical forest area. This country characterized by an enormously varied topography of shallow coastal water, swamp, lakes, alluvial plains, volcanoes, and High Mountain ranges. This country also presents at least forty-seven distinct natural and man-made ecosystems. These ecosystem types ranges from the ice mountain ecosystem and alpine grassland on the high mountains in Papua (Puncak Jaya Wijaya, at an altitude of over five thousand metres0 to variations of tropical rainforest ecosystems– from lowland to mountain landscape, shallow swamp to deep lakes, from mangroves to algae communities and coral reefs – as well as an ocean ecosystem reaching as deep as eight thousand meters below sea level (MoF/FAO, 1991).Unfortunately, little respect has been given to the high diversity of the archipelago, resulting in disappearance of many of these cultures. Studies to document and learn traditional wisdom are needed urgently, not least because traditional knowledge is often compatible with sustainable development objectives, as discussed in the World Summit on Sustainable Development, in Rio de Janeiro, 1992 and in Johannesburg in 2002. Meanwhile the deforestation in Indonesia occurs at an alarming rate. Forest cover decreased from about 193.7 million hectares in 1950s (Hannibal, 1950) to 119.7 million hectares in 1985 and to 100 million hectares in 1997 (GOI/World Bank, 2000) and only 98 million hectares remain (FWI/GWF, 2001).The local knowledge of environment management and indigenous custom, as part of indigenous culture, is the product of long interaction between man and their environment and also results of their ability for application the technique adaptation to their environment. High biological diversity has utilized for economic reason, even though this national asset has not yet been fully developed.Dynamic interaction between people and biodiversity in Indonesia let to the creation of many different cultures and thus languages and dialects. More than four hundred Indonesian ethnic groups are dispersed in different regions. Indonesia boasts665 different languages and dialects, with Papua accounting for 250 of these, Moluccas 133, Sulawesi105, Kalimantan 77, Nusa Tenggara (Lesser SundaIslands) 53, Sumatra 38, Java and Bali 9 (Grimes,1988). Such ethnics have specific knowledge about how to manage their environment and biodiversity surrounding them. Every ethnic has a specific culture, knowledge and local wisdom and technique adaptation to their various environments.Concerning the cultural richness in Indonesian, besides have advantages also constitute weaknesses for biodiversity resource management. One of these advantages is that we have various referable traditional pattern and alternative selection of space management and we have material to design system admissible management by all societies and also government. Meanwhile its weakness is that each ethnic has specific pattern according to environmental condition and cultural level. But along with time developing marks sense decentralization of policy in Indonesian, therefore local or region policy that based on actual condition area and society is more elegant compared with uniformity management which hasn’t obviously fastened byother area that has different culture and environmental condition.

The Objective of this study is to analyze the potential for biodiversity and traditional knowledge in the buffer zone of the Giam Siak Kecil-Bukit Batu Biosphere Reserve (GSK-BB). The research was conducted descriptively-quantitatively by analyzing two variables, i.e. biodiversity and community traditional knowledge. Biodiversity monitoring report documents from PT Sakato Pratama (PT SPM) and PT Bukit Batu Hutan Alam (PT BBHA), profiles of Temiang and Sepahat villages, questionnaire data taken from village community representatives, as well as the results of in-depth interviews were used in the analysis. The results show that in the PT SPM area, there are 177 species of plants and 55 species of animals. Meanwhile in the PT BBHA area there are 146 species of plants and 46 species of animals. Based on information from the community of Temiang Village, there are 51 species of plants and 18 species of animals, while according to the people of Sepahat Village, there are 73 species of plants and 83 species of animals. The biodiversity utilized by the community in the two villages consists of 36 species of plants and 15 species of animals, but only three species are wild animals, i.e. sun bear (Helarctos malayanus), horseshoecrab (Limulus sp.), and seahorse (Hippocampus sp.) .), and one species of plant (rattan, Calamus sp.). The rest are cultivated plants and livestock. From the analysis, it can be concluded that the relationship between biodiversity and traditional knowledge in both Temiang and Sepahat Villages is very limited. Awareness of the strategic value of wild plants and wildlife in the buffer zone of the biosphere reserve needs to be increased.Penelitian ini bertujuan untuk menganalisis potensi keanekaragaman hayati dan pengetahuan tradisional di zona penyangga Cagar Biosfer Giam Siak Kecil-Bukit Batu (GSK-BB). Penelitian dilakukan secara deskriptif-kuantitatif dengan menganalisis dua variable, yaitu keanekaragaman hayati dan pengetahuan tradisional masyarakat. Dokumen laporan monitoring keanekaragaman hayati dari PT Sakato Pratama (PT SPM) dan PT Bukit Batu Hutan Alam (PT BBHA), profil Desa Temiang dan Sepahat, data kuisioner yang diambil dari perwakilan masyarakat desa, serta hasil wawancara mendalam digunakan dalam analisis. Hasil menunjukan bahwa di kawasan PT SPM tercatat terdapat 177 jenis tumbuhan dan 55 jenis satwa. Sementara itu di kawasan PT BBHA terdapat 146 jenis tumbuhan dan 46 jenis satwa. Berdasarkan informasi dari masyarakat Desa Temiang terdapat 51 jenis tumbuhan dan 18 jenis satwa, sedangkan menurut masyarakat Desa Sepahat terdapat 73 jenis tumbuhan dan 83 jenis satwa. Keanekaragaman hayati yang dimanfaatkan oleh masyarakat di kedua desa tersebut terdiri atas 36 jenis tumbuhan dan 15 jenis satwa, namun hanya tiga jenis yang merupakan hewan liar, yaitu beruang madu (Helarctos malayanus), belangkas (Limulus sp.), dan kuda laut (Hippocampus sp.), serta satu jenis tumbuhan (rotan, Calamus sp.). Selebihnya merupakan tanaman budidaya dan hewan ternak. Dari hasil analisis, dapat ditarik kesimpulan sementara bahwa hubungan keanekaragaman hayati dengan pengetahuan tradisional di kedua desa Temiang dan Sepahat sangat terbatas. Kesadaran tentang nilai strategis tumbuhan dan satwa liar yang ada di kawasan penyangga cagar biosfer perlu ditingkatkan.

The objective of the study was to obtain data on composition and structure of the forest in the midsection of the Bukit Duabelas National Park core zone, designed to complement the existing data and provide new information potentials for the management of the park core zone. The study was carried out in October-November 2012. Observations were made on plots of one hectare (100 m x 100 m), which was divided into 100 subplot, measuring 10 m x 10 m each. Enumeration of tree species with diameters ≥ 10 cm revealed that as many as 540 individuals were recorded, consisting of 89 species and 36 families, with a total basal area of 30.837 m2 and only three species of Dipterocarpaceae were registered. The forest had a low diversity as indicated by low species richness, much lower than in the undisturbed lowland primary forests in the Batang Gadis National Park in North Sumatra, where similarity was very low (5.9 %). The forest in the plot was designated as the Dacryodes rostrata- Shorea leprosula Association, named after two species with highest importance values, thus the dominant. The structure and species composition pointed to the regenerating forest after heavy disturbances. The forest has been undergoing slow natural succession, leading to the formation of the forest similar to the original climax forest. Natural recovery through succession could be enhanced and assisted by means of ecological restoration, through planting of tree species characteristics of forests in Jambi, including species of Dipterocapaceae, useful species having values to maintain the livelihood of the indigenous native tribe Suku Anak Dalam and rare, endemic other species having high conservation values. Tujuan studi ini adalah untuk memperoleh data tentang komposisi dan struktur hutan di bagian tengah zona inti Taman Nasional Bukit Duabelas. Studi dirancang untuk melengkapi data yang telah ada dan untuk menyajikan informasi baru yang berpotensi untuk digunakan dalam pengelolaan zona inti taman nasional. Penelitian dilaksanakan pada bulan Oktober-November 2012 dalam petak seluas satu hektare (100 m x 100 m), yang dibagi menjadi 100 anak-petak dengan ukuran masing-masing 10 m x 10 m. Pencacahan pohon dengan diameter ≥ 10 cm menghasilkan 540 batang, yang terdiri atas 89 jenis dan 36 suku, dengan luas bidang dasar total 30.837 m2 dan hanya tercatat tiga jenis Dipterocarpaceae. Keanekaragaman jenis hutan rendah, seperti ditunjukan oleh rendahnya kekayaan jenis, jauh lebih rendah dibandingkan dengan hutan primer yang tidak terganggu di Taman Nasional Batang Gadis di Sumatra Utara, yang mempunyai kesamaan hanya 5,9 % dengan Taman Nasional Bukit Duabelas. Berdasarkan dua jenis dominan dengan nilai kepentingan tinggi, komunitas pohon dalam petak dinamakan Asosiasi Dacryodes rostrata- Shorea leprosula. Struktur dan komposisi jenis menunjukan status hutan sebagai hutan yang sedang beregenerasi setelah mengalami gangguan. Hutan sedang mengalami suksesi alami yang lambat menuju ke pembentukan hutan yang serupa dengan hutan klimaks aslinya. Pemulihan alami melalui suksesi dapat dipercepat dan dibantu dengan restorasi ekologi melalui penanaman jenis-jenis khas hutan alami Jambi, termasuk Dipterocapaceae, jenis-jenis bermanfaat dan mempunyai nilai untuk keberlanjutan kehidupan dan kesejahteraan masyarakat asli Suku Anak Dalam dan jenis-jenis langka, endemik dan jenis lain yang mempunyai nilai konservasi tinggi.

The objective of research is to find out the differences and similarities of insect diversity, abundance and composition between in industrial plantation forest (HTI) and natural forest (Arboretum) ecosystems. Field research was carried out in the Rasau Kuning area, Perawang Barat Regency, Riau Province, while specimens identification conducted at LIPI Biology Research Center Laboratory in February - March 2019. Line transect sampling technique and fluorescent light traps were used as methods for collecting insects from both two different ecosystems with three replications. The results found five order of insects i.e. Lepidoptera, Hemiptera, Coleoptera, Orthoptera, and Hymenoptera which consisting of 35 species in plantation forest ecosystem, and 26 species in natural forest ecosystem where both ecosystems dominated by Lepidoptera. Statistical analysis of research results show that two average insects species diversity index within both plantation forest (HTI) and natural forest (Arboretum) ecosystems is not different (t = 1,419; p0,05). The similarity index found very similar (23,56%) between both ecosystems. Predatory insects which was found in this study is Sycanus sp. (Hemiptera: Reduviidae) from the order of Lepidoptera.Penelitian ini bertujuan untuk mengungkapkan perbedaan dan kesamaan keanekaragaman jenis, kelimpahan, dan komposisi jenis serangga antara di ekosistem hutan tanaman industry (HTI) dengan ekosistem hutan alam (Arboretum). Penelitian lapang dilakukan di areal Rasau Kuning, Kabupaten Perawang Barat, Provinsi Riau, sementara identifikasi specimen dilakukan di Laboratorium Pusat Penelitian Biologi LIPI, pada bulan Pebruari - Maret 2019. Metode sampling line transect dan perangkap cahaya berflouresen digunakan untuk menangkap serangga di kedua ekosistem tersebut melalui 3 kali ulangan. Hasil studi menemukan 5 ordo serangga yaitu Lepidoptera, Hemiptera, Coleoptera, Orthoptera, and Hymenoptera, dengan masing-masing 25 spesies terdapat di ekosistem hutan tanaman (HTI) dan 26 spesies di ekostem alam (Arboretum), yang mana keduanya didominasi ordo Lepidoptera. Melalui analisis statistik, hasil penelitian menunjukkan bahwa pada kedua ekosistem tidak terlihat adanya perbedaan indeks keanekaragaman jenis (t =1,419; p0,05). Begitu juga dengan indeks kesamaan menunjukan tingkat yang sangat sama (23,56%) antara kedua ekosistem tersebut. Pada kajian ini juga ditemukan spesies serangga predator yaitu Sycanus sp. ((Hemiptera; Reduviidae) dari ordo Lepidoptera.

An analysis of the growth dynamics of a 1-ha (100 m x 100 m) permanent plot was carried out in the Danau Bangko Protected Area (DBPA) in March 2020. DBPA is part of the industrial plantation forest concession of PT Rimba Hutani Mas (PT RHM) in Jambi Province. The study aims to determine the dynamics of vegetation structure and composition between 2018 and 2020 in early regeneration forest. All trees tagged in 2018 were remeasured in 2020. Trees that had not been tagged previously but were 10 cm in diameter at breast height (DBH) were identified as a new recruit and tagged with a new number. Observations and data analysis were carried out on three stages of growth phases, namely in the tree phase ( 10 cm DBH), sapling phase (10 cm DBH), and seedling phase (height 1.5 m). The results showed that the number of species, genera, and families within the tree and sapling phases were high, but were low in the seedling phase. The dominant species in the tree phase in 2018, Alseodaphne bancana, had been replaced by Archidendron bubalinum in 2020, whereas the dominant species in the sapling phase (Rothmania sp.) and seedling phase (Aporusa microsphaera) remained the same from 2018 to 2020 . Mortality rates in all growth phases (tree, sapling and seedling) together is 4.67%. Recruitment into the tree phase from 2018 to 2020 was 2.67%, consisting of eight species, eight genera, and seven families. Within one hectare permanent plot, all members of each tree species were distributed randomly. The vertical structure of the forest area is dominated by stratum C (4-20 m height). The results of hypothesis testing for each phase (tree, sapling, seedling) were different, however overall the results showed that the plot structure and composition had changed.Studi dinamika hutan dilakukan di Kawasan Lindung Danau Bangko (KLDB) pada Maret 2020 dengan menggunakan pendekatan plot permanen seluas satu hektar (100 m x 100 m). KLDB merupakan bagian dari konsesi hutan tanaman industri PT Rimba Hutani Mas (PT RHM) di Provinsi Jambi. Penelitian ini bertujuan untuk mengetahui dinamika struktur dan komposisi vegetasi antara pengukuran tahun 2018 dan 2020, khususnya pada areal dengan tutupan Belukar Tua (BT). Diameter semua pohon yang telah diberi tanda nomor pada tahun 2018 diukur kembali. Pohon yang belum diberi tanda sebelumnya tetapi diameternya 10 cm setinggi dada (DBH) ditetapkan sebagai rekrutmen baru dan diberi tanda dengan nomor baru. Pengamatan dan analisis data dilakukan terhadap tiga tahap tahap pertumbuhan, yaitu tingkat pohon (10 cm DBH), tingkat pancang (10 cm DBH), dan tingkat semai (tinggi 1,5 m). Hasil penelitian menunjukkan bahwa jumlah spesies, jumlah marga, dan jumlah famili pada tingkat pohon dan pancang tinggi, sedangkan pada tingkat semai rendah. Jenis dominan pada tingkat pohon pada tahun 2018 adalah Alseodaphne bancana telah digantikan oleh Archidendron bubalinum pada tahun 2020, sedangkan pada tingkat pancang (Rothmania sp) dan tingkat semai (Aporusa microsphaera) merupakan jenis yang dominan baik pada tahun 2018 maupun pada tahun 2020. Angka kematian pada semua tahapan pertumbuhan bervariasi dengan rata-rata 4,67%. Rekrutmen di tingkat pohon 2,67% yang terdiri dari 8 spesies, 8 marga, dan 7 famili. Secara keseluruhan, semua spesies tersebar secara acak. Tinggi tajuk pohon didominasi oleh stratum C (tinggi 4 m - 20 m). Hasil pengujian hipotesis pada setiap tingkatan (pohon, pancang, semai) berbeda, namun hasil penggabungan semua data menunjukkan bahwa telah terjadi dinamika.
