The Subject

Conservation of genetic resources of forest trees has become a major objective for the management of forests. Much theoretical work has been devoted to the subject, and implementation has already started at the local, national, or international scales. Poplars are probably the most representative and threatened forest tree species of old natural floodplain forests in the temperate zone. Gene conservation needs to be integrated with intensive breeding activities, habitat conservation and restoration. For Populus nigra, while research in genetics and ecology is reinforced, a combined conservation strategy is applied at the European scale; simultaneously, the conservation of riparian ecosystems is also a priority. Research and application benefit from each other. The question now is the evaluation of such an integrated strategy. Criteria and indicators for the follow-up of gene resource management are progressively developed, but still need to be tested on the operational scale. Key words: Populus nigra, poplar, gene resources, in situ conservation, ex situconservation, riparian ecosystem, sustainable management

Threatened Habitat

The distribution of the threatened fern Ophioglossum vulgatum L., a plant with extremely small populations (PSESPs) in Sardinia, is characterized by small disjunct populations with only a few individuals, and little is known about its status in the wild. To provide information for the conservation of O. vulgatum and with the aim to develop an in situ conservation strategy, we investigated its distribution, population size, and habitat. Field surveys confirmed that the species grows in only five localities. Two representative populations were selected for this study (Funtanamela and Gedili), and in each population, all plants were mapped and monitored monthly from April to August over an 8-year period. During the study, the populations had a very low number of reproductive plants and the populations appeared to be in decline, with the total number of plants per population slightly decreased in Gedili while a sharp reduction was recorded in Funtanamela due to wild boar threat. A fence was built in order to protect the site from further damage, but no noticeable signals of recovery were observed. The most urgent conservation requirement for this species is to preserve the threatened habitat of the remnant populations. Further field surveys and research are also required for an improved understanding of the species’ status.

The Future

Animal genetic resources such as indigenous chickens are part of biodiversity. Sentul chickens are one of indigenous chickens in Indonesia which are regarded as local to Ciamis District in West Java.  It is reported that the population of pure Sentul Chickens are in decline. This study was aimed to find out the current population of pure Sentul chickens in three areas in West Java and to develop a conservation strategy to safeguard Sentul chickens in the future. The study used qualitative method to gather data including literature review and key informant interviews. The informants consisted of a leader of farmer group and managers of breeding centers. The interviews were carried out in Ciamis, Majelengka and Bogor Districts. The data were analyzed by descriptive analysis. The results indicated that population of Sentul chickens in Ciamis are in decline, while population in areas outside Ciamis such as Bogor tend to increase. There is a need to develop an in-situ conservation program in which Ciamis District should be assigned to be the center area to provide pure Sentul chickens in West Java. To support the conservation program, stakeholders such as local government, research institutions, universities and farmer groups play important roles. Keywords: in-situconservation strategy, Sentul chickens, animal genetic resources, biodiversity.

To understand the contemporary and anticipated future (future 30–50 years) distribution of Chinese wild yellowhorn (Xanthoceras sorbifolium Bunge) and to improve the species’ in situ conservation strategy within the network of China’s National Nature Reserves (NNR), we used BiodiversityR to predict the species’ distribution utilizing the “always-suitable” map concept. We then delineated the always-suitable distributions with the existing NNRs to identify potential conservation areas using an approach that concurrently considered spatial distribution, gap analysis, the role of climate change, and economic analyses. Seven bioclimatic variable predictors and 12 environmental niche modelling submodels successfully contributed to the final model assembly (AUC = 0.916, κ = 0.398). The species range delineation indicated that 71 of the 427 NNRs were included in the always-suitable area, accounting for 26 007 km2 (1.58%) of the species total distribution. This mapping endeavour highlighted the negative impact of climate change with a projected 15%–20% habitat decline and expected species’ distribution centers shifting from the country’s northwest to the southeast. Our results predict the continuous deterioration of X. sorbifolium because of its existing utilization as an oil source and its increased bioenergy potential. The adoption of a flexible management strategy embracing acceptable trade-offs between conservation and utilization within China’s NNRs could effectively alleviate the expected species decline.

Tree Level

Abstract Kuskus, a marsupial species belonging to the Phalangeridae family that is vulnerable in the IUCN Redlist, is one of the endemic animals whose survival is currently very concerning due to habitat destruction and poaching, so conservation activities need to be carried out immediately. This study aims to identify the characteristics of the habitat, type of feed, and in situ conservation strategies in the Wakasiu forest, Leihitu Barat sub-district, Central Maluku district. This research was conducted in October 2020. Habitat characteristics were identified using vegetation analysis, forage types were identified using direct and indirect observations, and insitu conservation strategies using SWOT analysis. The highest index of importance at the tree level in the line of observation is the type of gayam (lnocarpus fagifer) (20.19%), at the level of weaning is the langsat species (70.32%) the level of the pole type of brown (69.27%). The diversity level of plant species is high and the level of evenness of plant species is even. There are 24 types of plants recorded as potential for special feed. The in-situ conservation strategy that is carried out is planting the type of feed preferred by the specialists, so as to provide a stable feed availability during the successive fruiting period. Apart from that, the restriction of hunting for specialties is through written regulations and the imposition of sanctions.

Abstract North Sulawesi is one of the provinces which is included in the Wallacea area which is the world’s source biological diversity and endemism hotspot. Forest fragmentation and population growth is the greatest threat to a variety of Wallacea endemic species. This study aims to explore the plant diversity in various forest patches in North Sulawesi and their conservation strategies. The research was conducted in 7 forest locations. This research uses exploration method. Exploration results found 259 collection numbers consisting of 154 species, 114 genera and 53 families. Orchidaceae is the most commonly family found (48 species and 26 genera), followed by Moraceae (18 species) and Piperaceae (16 species). Four species of Begonia were identified as endemic Sulawesi, 3 number potential as new species. Potential of new species is also likely on the Alpinia spp. (Zingiberaceae) and Piper spp. because has a large variety. Forest patches in the study area still have a high variety of species but mostly surrounded by people’s gardens and exploited potentially. In situ conservation complementary with ex situ is a conservation strategy which needs to be carried out.
