Abstract
Schizolobium parahyba, a fast-growing tree species from South America, was introduced to Indonesia as a potential timber source. This study aimed to evaluate the effects of heat-treatment at 150-200 ºC (4h) on the physical and mechanical properties of S. parahyba wood. The results show that weight loss (WL) increased from 2.62 ± 0.29% at 150 ºC to 9.22 ± 0.86% at 190 ºC, while anti-swelling efficiency (ASE) increased from 3.44 ± 0.78% at 150 ºC to 29.84 read more

Abstract
The Mutis-Timau Forest Complex, Timor Island, in eastern Indonesia has limited forest resources and is threatened by deforestation and degradation. Consequently, forest and natural resource management policies have prioritized on nontimber forest products (NTFPs) development. Although not yet designated as superior NTFPs in Timor, several native medicinal plants – faloak (Sterculia quadrifida), screw tree (Helicteres isora), and beard lichen (Usnea barbata) read more

Abstract
Field surveys for rare and endangered species are essential to identify new populations and improve the understanding of their natural distribution for effective conservation but are often constrained by limited prior information. In the present study, the fieldwork guided by species distribution models (SDMs) and local ecological knowledge (LEK) was conducted to discover previously unknown distributions of endangered Castanopsis argentea and C. tungurrut on read more

Abstract
In the era of urbanization, urban forests play a crucial role in connecting biodiversity conservation and human well-being, providing recreational and tourism benefits in urban areas. This study aims to analyze the intersection of urban forests, biodiversity conservation, and their interaction with visitors, including preferences, perceptions, and behavior. We examine 83 open-access articles published between 2010 and 2025, retrieved from Scopus databases, read more

Abstract
The Bintan Island Pale-thighed Langur (Presbytis siamensis rhionis), or Bintan langur, is an endangered subspecies endemic to Bintan Island, Indonesia. Despite its threatened status under the IUCN Red List, it remains unprotected under Indonesian law. The langur’s habitat overlaps with the Bintan Resorts Tourism Area, where increasing tourism development and human activities may alter its distribution and habitat use. Understanding spatial distribution through read more

Abstract
Parasitism is a disease that commonly occurs in ruminants, including wild native Timor deer (Rusa deer). Variation of parasite types in wild Timor deer in three national parks (NP) in Indonesia, namely Baluran NP, Alas Purwo NP, and West Bali NP, has never been done. This research aimed to detect the types, number, prevalence, and diversity of gastrointestinal parasites in wild Timor deer (Cervus timorensis) in the three national parks. The research used a read more

Abstract
Limited information on the yield and quality of fodder, fuelwood, and food crops of post-taungya teak plantation systems often hinders further development. Therefore, this study aims to evaluate the yield and quality of fodder, fuelwood, and food crops under teak stands in three-strata agroforestry of post-taungya plantation systems. Fodder and fuelwood species (Calliandra calothyrsus) and food crops (Canna edulis) were planted in a split-plot design. Main read more

Abstract
Societal impact statement
Major staple crops are often introduced and cultivated in monocultures. Yams are staple crops native to the majority of low- and middle-income countries and can provide an alternative to introduced staple crops. [Correction added on 9 January 2026, after first online publication: In the preceding sentence, stable has been corrected to staple in this version.] We showed that lesser yams cultivated together with teak trees (planted read more

Abstract
The Mutis Timau is essential in community life and ecological conservation. However, the ecosystem has experienced disturbances and changes in its status, which have influenced land use and land cover. This research aims to predict land cover change in 2030 in the Mutis Timau. This research uses Landsat 7 ETM+ from 2011 and Landsat 8 OLI/TRIS from 2016 and 2021. The variable used Shuttle Radar Topography Mission digital elevation data. Data processing was carried read more
