Abstract

One of the ecological challenges in managing conservation areas is the colonization and establishment of alien and/or native plant species, especially after forest disturbances. The capacity stakeholders to determine the invasiveness risk of these plant species groups and then management strategies to monitor changes in vegetation structure and species composition is critical. The community engagement program aims to improve the capacity of conservation area stakeholders to identify plant species, including invasive species, and assess the risk of invasive species. Focus group discussion (FGD) were conducted online and offline and targeted stakeholders of the Natural Resources Conservation Agency (Balai Konservasi Sumber Daya Alam–BKSDA) of Central Java Province. Three FGD sessions were held on the topics: (1) forest monitoring and invasion ecology, (2) plant species identification and invasive species monitoring techniques, and (3) vegetation and invasiveness risk analysis. During the discussion, target groups shared ideas and lessons learned related to managing invasive species in the field. The results showed a significant increase in the capacity of the target group (p=4.546e-09), as the average pretest score was 56.25 ± 13.68 compared to the average posttest score of 75.70 ± 20.27. The target group understands the definition of an invasive (alien) species, the factors that determine the success of this species invasion, and the positive and negative contributions alien species to the newly established ecosystem. Some gaps that need to be addressed relate to methods and criteria for identifying species invasiveness in invasive species risk analysis. As a follow-up, a practical training on invasive (alien) species risk analysis was conducted at different occasion and funding sources.

Abstract

ARTICLE HIGHLIGHTS- The article introduces an evaluation of mangrove habitat suitability for ecotourism in the Progo River area, which has not been extensively studied in this region.- It employs nested and gridline sampling methods to measure habitat quality more comprehensively, leading to more accurate data on mangrove conditions.- The study examines the impact of physical and chemical factors such as temperature, salinity, and dissolved oxygen on mangrove growth and biodiversity.- It uses the Tourism Suitability Index to identify locations suitable for nature tourism activities around the Progo River.- The article stresses the need for improved management of mangrove ecotourism areas to preserve ecosystem sustainability and support the local economy. ABSTRACTMangrove forests are a transitional ecosystem located between land and sea. Habitat factors greatly influence the growth of mangrove plants. Habitat suitability is reflected in the suitability of the species that can grow in the habitat. Increased growth will ultimately increase water productivity, which can be seen from the presence of various types of biota and environmental improvements. The local community planted mangrove species (Sonneratia sp.) along the Progo River in an area of 75 h. This study aimed to: 1) assess the quality/characteristics of the Progo River waters that will be used for a water tourism center and 2) assess the suitability (IKW) of the Progo River waters for water tourism in Bleberan Hamlet. Data collection was carried out using nested sampling. Data analysis included the diversity of biota types using the Shannon Diversity Index and vegetation analysis. The results showed that the highest temperature occurred at station 3 plot 10, the highest mud thickness was observed at station 5 plot 9, the highest salinity was detected at station 3 plot 10, the highest water clarity was observed at station 2 plot 7, the highest pH was seen at station 1 plot 6 and 7, while the highest DO was spotted at station 3 plot 8. Some of the biota obtained included crustaceans, gastropods and actinopterygii. The habitat types of vegetation obtained were trees, shrubs, and some herbs. Based on the Tourism Suitability Index (IKW) value, there were 3 stations suitable for camping/outbound, 2 stations suitable for relaxing, and 2 stations suitable for river tracks.

Abstract

Pembukaan hutan mangrove menjadi tambak diakibatkan oleh permintaan hasil-hasil perikanan dan hasil lainnya seperti kepiting bakau, dan udang yang semakin meningkat telah merusak ekosistem mangrove. Usaha untuk memulihkan fungsi ekosistem mangrove salah satunya melalui kegiatan rehabilitasi yang meliputi penghijauan pantai dengan menanam mangrove dan dengan memanfaatkan silvofishery. Penelitian ini bertujuan untuk (i) menganalisis faktor fisis, kimia, dan biologis habitat mangrove pada tahun tanam 2001, 2003, dan 2004 (ii) mengidentifikasi lokasi mana saja yang sesuai untuk dijadikan sebagai areal silvofishery pada tahun tanam 2001, 2003, dan 2004. Penelitian dilakukan dengan cara membagi kawasan rehabilitas mangrove menjadi 3 jalur sebagai ulangan dan tegak lurus garis pantai dengan jarak antar jalur 25 m. pada setiap jalur dibagi menjadi 3 zona ke arah darat. Pada setiap zona dibuat PU ukuran 5m x 5m, sehingga total ada 36 PU. Pada setiap PU diukur suhu, DO, salinitas, pH air, ketebalan lumpur, dan kerapatan vegetasi, plankton dan nekton. Hasil penelitian ini menunjukkan bahwa tidak ada lokasi yang sesuai untuk dijadikan sebagai silvofishery, karena beberapa faktor yang belum mendukung pada saat itu, sehingga perlu dilakukan perbaikan dengan cara penelitian lebih lanjut mengenai silvofishery ini dan faktor-faktor yang belum memenuhi kriteria habitat mangrove dalam tabel kesesuaian ekologis tersebut.

Abstract

Way Kambas National Park (WKNP) in Lampung serves as a critical habitat for the endangered Sumatran elephant (Elephas maximus sumatranus). However, the area has increasingly experienced human-elephant conflicts, particularly at the Rawa Bunder Resort. This research aimed to assess the biophysical characteristics and map the distribution of potential elephant habitats within the resort area. Field data were collected using 70 nested plots distributed along established transects and analyzed through a modified sampling protocol. An Agglomerative Hierarchical Cluster (AHC) analysis was employed to classify the habitats into suitable, moderately suitable, and less suitable categories. The georeferenced plot data were processed using ArcGIS 9.3 to create a habitat suitability map. The findings indicated that 24% of the plots were classified as suitable, 33% as moderately suitable, and 43% as less suitable. The suitable habitats were predominantly located in lowland forest areas, which represent a relatively small proportion of the total area. To expand suitable habitats and mitigate human-elephant conflicts, strategic habitat management measures, such as forest restoration and targeted enrichment, are essential. These results provide a spatial framework for conservation planning for elephant habitats in Way Kambas and other fragmented landscapes.
