A comprehensive survey was conducted across 63 urban parks, gathering subjective feedback from park visitors on park size, vegetation, and exposure to external disturbances. Objective metrics were the area of the park, the mean and stdev of the Sentinel-2 NDVI as measures of vegetation density and diversity, respectively, distance to other parks and the park perimeter-to-area ratio. Linear and non-linear regression analysis between subjective feedback and objective metrics revealed that satisfaction peaks in parks with sizes of 15 ha or more. Higher vegetation density maximizes satisfaction. Parks with simpler, more regular shapes tend to offer a greater sense of freedom from external disruptions. According to the Generalized Additive Model model (R²= 0.737, explained deviance = 77.1 %), lush and healthy vegetation is often associated with attractive and inviting parks, especially in parks with simpler, more regular shapes that minimize the exposure to (noise and visual) disturbances. Such green and circular park designs can guide urban planners and managers in creating inviting and user-friendly parks, aligning with public expectations.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"18 ","pages":"Article 100729"},"PeriodicalIF":2.7,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142652370","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}

For this study, we generated primary baseline data on tree species diversity, biomass, and carbon stock for forests under different management regimes in one of the critical landscapes of western Nepal. We sampled 94 clusters of concentric circular sample plots placed systematically at the nodes of 3 km by 3 km square grids in biological corridors (managed by community forest user groups) and a national park's buffer zones (managed by buffer zone user groups) to study the tree species composition and estimate the carbon stock. The number of tree species and botanical families reported in different sites did not differ significantly. The basal area was found to be highest in Brahmadev Corridor where tree density per unit area was also highest. Our study sites showed a basal area ranging from 26.42 to 40.65 m²/ha, which is higher than previously reported from similar forests. The total biomass (302.12 to 496 tons/ha) and carbon stock (142 to 233.12 tons/ha), both being highest in Brahmadev Corridor, were within the range of comparable data and national averages. The number of stems in all sites showed the reverse J-shaped pattern, indicating a stable population and good species recruitment. The buffer zones had a large proportion of forest area with the highest carbon stock classes of 300–400 tons/ha. The basal area and diameter at breast height showed a significant positive correlation with carbon stock, indicating that the basal area is a key determinant of carbon stock. Our study provides disaggregated information on tree species diversity, the quality of forests in terms of stem density and size-class distribution, and carbon stock and its distribution in different carbon stock classes in two forest management regimes. In this sense, our study is the first of its kind in providing important insights into forest and carbon management because areas with different carbon stocks need different management prescriptions.</div></div>","PeriodicalId":36104,"journal":{"name":"Trees, Forests and People","volume":"19 ","pages":"Article 100728"},"PeriodicalIF":2.7,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722573","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}

Household interviews (HHIs), focus group discussions (FGDs) and key informants’ interviews (KIIs) were used to investigate the level of harvesting and utilization of fruits from different tree species of jujube in Ethiopia. Multiple linear and binary logistic regressions were utilized to investigate factors influencing the annual fruit yield per tree and to discern factors impacting the local community's capacity to grow and sell jujube, respectively. Fruit yield per tree, market involvement and the principal challenges to growing were found to vary among two study sites. Bosset district's yield exceeded Bati's by 0.87 times.

Less rainfall reduced annual yield by 33 kg per tree while planting seedlings instead of relying solely on naturally regenerated trees boosted yield by 42 kg per year.

The increasing impact of pests, water shortage and cultural influences decreased community interest in growing jujube by factors of 1.15, 1.41 and 2 times, respectively.

Additional losses of the pine population on the island were results of the major hurricanes in the post-logging era. There were ca. 43 million pine trees in Grand Bahama before the 2004 and 2005 major hurricanes. This study uses ridge regression and a nested linear mixed-effects model (with a random intercept included as the variance-covariance structure) to reconstruct and compare Grand Bahama pine forest age across different domains (pre-Dorian dead, post-Dorian dead, and post-Dorian live pine areas). Statistical results revealed that the mature pine forest (DBH ≥ 10 cm) in Grand Bahama in 2004 ranged in age from 38 to 49 years old. These are the pine seedlings that germinated between 1950 and 1970 during and at the end of the logging era in Grand Bahama. The intraclass correlation coefficient (ICC [1]) indicated that the nesting effect (survey plots within domains) in the linear mixed-effects model (LMM) explained 33.8% (ICC [1] = 0.338) of the total variance captured by the grouping effect of pine forest age.

The rationale behind this approach is the assumption that the additional disturbance caused by the removal of standing deadwood after stand-replacing fire is of no further significance for the already heavily disturbed ecosystem. However, while there is a global debate on effects of salvage logging for regeneration success, biodiversity, and soil health, little evidence has been collected from strongly drought-limited southern boreal forests of Central Asia. Comparing sites with and without salvage logging, we investigated forests of Siberian larch (<em>Larix sibirica</em>) ca. 20 years after stand-replacing fire and asked whether postfire salvage logging affected regeneration density, terminal shoot length and radial stem increment, ecosystem carbon stock densities, and reduced organic layer depth and compacted the soil. The biomass of the larch regeneration was significantly reduced by salvage logging, while tree growth was not affected. The ecosystem carbon stock density of burnt forest without salvage logging was 202 Mg C ha⁻¹ and thus even in the lower range of intact larch forests from Mongolia, whereas burnt forests with salvage logging had organic carbon stock densities (104 Mg C ha⁻¹) that were lower than those of unburned grasslands in the forest-steppe. These results show that removing deadwood from burnt forest is not insignificant, but has the potential to delay forest recovery and strongly reduces organic carbon storage. However, we did not find significant reductions in soil organic carbon stocks or soil compaction.
