This study documented traditional medicinal plants and community practices in the Melokoza from 2023 to 2024. A purposive sampling technique was employed to select sampled Kebeles. Overall, 390 respondents were identified to gather information on medicinal plants using a questionnaire survey. Preference Ranking, Fidelity Level, and Informant Consensus Factor were used to analyze the data. In general, 140 medicinal plants grouped into 115 genera of 56 families were identified in this study. Asteraceae was the most dominant family representing 19.3 % of the medicinal plants identified, followed by Lamiaceae (13.57 %). Leaves were the most commonly used part of the plants, making up 67.9 % of the plant parts used, followed by roots (10 %). Fresh plant parts were mainly used for medicine (85.71 %). Most medicinal plants were found in home gardens (27.86 %) and forest areas (22.86 %). Cold water extraction (56.92 %) was the most common method of traditional medicine preparation, followed by crushing (19.23 %). The most common way to take medicine was by drinking it in solution form. <em>Croton macrostachyus</em> was noted for its high preference ranking in treating wounds. The highest informant consensus factor value was recorded for stopping bleeding (0.98) and stopping vomiting (0.97) illness.

The research addresses the pressing issue of soil degradation in Fasola area of Oyo State, Nigeria.A silvopastural system established over three decades was assessed and compared with conventional arable land using a fixed grid sampling technique across 30 sampling locations for each land-use system within a 1000 ha. The assessment focused on the topsoil layer of 0–20 cm depth. The soil samples were analyzed for pH, organic carbon content, total nitrogen, available phosphorus, and other exchangeable cations and the soil micronutrients, using wet chemistry standard procedures. The results showed that the silvopastural system considerably enhanced soil fertility. Organic carbon increased by 290 %, total nitrogen by 183 %, and available phosphorus by 150 % compared to cropland soils. Additionally, concentrations of exchangeable cations, such as calcium (325 % increase), magnesium (400 % increase), and potassium (300 % increase), were substantially higher in silvopasture systems. Micronutrient levels, including zinc, copper, iron, and manganese, also significantly increased. The results show that silvopastural system provides a feasible technique for long-term soil fertility increases, delivering essential advantages for sustainable agriculture and soil management in the Guinea Savanna ecology. Silvopastoral system, through nitrogen cycling and water retention, may aid in the rejuvenation of degraded soils and improve crop productivity in nutrient-depleted soils.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"20 ","pages":"Article 100847"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808451","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}

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.

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.

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.
