In Nepal, elongated tortoises were widespread in lowland areas. However, tortoise and other wildlife populations declined exponentially in response to growing human population and associated interferences. The extent of the anthropogenic influences is expected to vary on a fine scale. Understanding this variation is crucial to design and implementation of conservation strategies, which are lacking at this time. This study was conducted with the aim of addressing information gaps about the behavior of the local people and how these behaviors may threaten the survival of <em>Indotestudo elongata</em> in Bara district, Central Nepal. As our focal species is a forest dependent tortoise, we conducted surveys using questionnaire in the vicinity of forest areas from three administrative units namely Kolhabi and Nijgadh municipalities and Jeetpur-Simara Sub-Metropolitan City. Among the survey participants, nearly two-thirds of them reported to have collected tortoise from forests and nearly equivalent number of participants reported consuming tortoises. This indicates that consumption, as food was the major reason for the collection. In the past, some of the remaining tortoise carapaces, were sold by the local inhabitants for nominal price. Respondents more recently, reported no incidence of trading tortoise or their carapaces, so many of them have discarded the carapaces as they do not have utility value. However, locals continue to collect the tortoise for non-commercial use when they encounter the species. Exploitation and consumption of tortoises was significantly associated with respondents’ ethnicity viz. local ethnic communities being more involved. Successful interventions may entail local involvement in activities that include reduction of forest dependency and awareness, to protect tortoises in their natural habitat.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"20 ","pages":"Article 100845"},"PeriodicalIF":2.7,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143823945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These events are characterized by canopy dieback and elevated mortality rates, but not all trees are equally affected with neighboring conspecifics showing contrasting vigor. Tree-ring data have been used to forecast die-off because of the contrasting growth rates declining (D) and non-declining (ND) trees show before tree death. However, discrete wood features such as latewood intra-annual density fluctuations (IADFs) have not been considered despite they record specific climate events. We hypothesized that D trees were less able to use water from rare summer-autumn rainfall pulses, which trigger IADF formation. We evaluated radial growth (tree-ring width) and latewood IADFs production in D and ND trees of two Mediterranean <em>Pinus pinaster</em> stands, which showed a strong die-off episode after the extreme 2017 drought. Wood anatomy and intra-annual growth rates and their climate drivers were also studied in one site, where dieback and mortality were annually monitored. The D trees significantly grew more in the past, particularly during wet decades, but tended to form less IADFs than ND trees, albeit differences were not significant. In the two decades before the die-off onset, ND trees formed tracheids with wider lumen and thicker walls than D trees. High precipitation in late summer and early autumn enhanced the formation of IADFs, a result supported by simulations of the Vaganov-Shashkin model. These findings suggest a greater ability of D trees to grow more in response to spring rainfall during wet periods, but a higher vulnerability in response to recent drought stress. In contrast, ND trees show a higher capacity to recover after the summer drought and to form latewood IADFs, a feature which can be further investigated as prognostic tool for die-off.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"20 ","pages":"Article 100843"},"PeriodicalIF":2.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research innovates by quantifying wood volume and carbon stock in two integrated systems, thereby providing insights into the key factors that optimize the quality of roundwood timber. Trees of <em>Eucalyptus urograndis</em> and <em>E. cloeziana</em> were monitored throughout their production cycle, and the evaluations for this study were carried out at 120 months after transplanting, prior to timber harvest. Longitudinal discs were removed from six trees per treatment at 2 %, 10 %, 30 %, 50 % and 70 % of the commercial height. We evaluated attributes such as bark content, heartwood to sapwood ratio, pith eccentricity, basic density and carbon content in the wood. To determine carbon stock, a total of 18 trees per treatment were sampled, with three trees selected from each of six diameter classes, representing the lower, middle, and upper diameter ranges, and their volumes were subsequently calculated using the Smalian method. Both genotypes showed wood quality associated with a bark content of &lt;3.5 %, acceptable pith eccentricity below 5 %, heartwood to sapwood ratio greater than one, percentage of heartwood greater than 50 %, and a high basic density of &gt;0.60 g/cm³, ideal indicators for using the wood in sawmills, the construction industry and rural areas.

In this context, this study aims to assess the impact of climate change on the distribution of <em>Sterculia setigera</em> Delile, a widespread species with significant socio-economic value found in different climate zones of Benin. Given the heterogeneity of environmental conditions in Benin, a crucial question remains: how does climate change affect each <em>S. setigera</em> population group? And what are the priority areas for <em>S. setigera</em> conservation? To address these questions, we subjected each subgroup to species distribution modeling (SDM) using the maximum entropy algorithm (MaxEnt). This approach was applied under Shared Socioeconomic Pathways (SSP 2–4.5) and SSP 5–8.5 climate scenarios. A test of niche similarity between the groups was performed to assess their level of conservatism. Habitat prioritization was performed using Zonation software. Our results showed three distinct homogeneous subgroups (north-SN, center-SC and south-SS) with differentiated climatic conditions. SN was affected mainly by mean temperature of the warmest quarter, SS by precipitation of driest month, isothermality and minimum temperature of coldest month, while SC by elevation, temperature Seasonality and mean temperature of coldest quarter. Current climatic conditions were suitable for <em>S. setigera</em> in all climate zones. Under future climate scenarios SSP 2–4.5 and SSP 5–8.5, SN increased, while SC decreased. The SS subgroups, showed a decrease in suitable conditions under the SSP 2–4.5 scenario but an increase under the SSP 5–8.5 scenario. However, among the subgroups there was niche differentiation, leading to the emergence of ecotypes. The protected area was prioritized for the conservation of <em>S. setigera</em> in Benin.
