Taking the Mogazang landscape of Cameroon as a case study, a mixed methods approach involving farmers surveys, key informant interviews and the review of literature, was applied to investigate the factors that influence the behavioural persistence of tree-growing farmers. Drawing on the concept of behavioural persistence, the findings revealed that farmers decision to continue restoration practices on their farm plots after the end of support programs is influenced by a mix of factors, among which positive attitude and perception of farmers, constant motivation, financial profitability, community influence, played an important role. Findings also showed that farmers behavioural persistence aspects were not adequately addressed during the design of support programs and the inception phase of support programs did not prepare farmers psychologically about post support programs. This empirical investigation of farmers behavioural persistence has provided information that needs to be taken into consideration when assessing the feasibility, including the designing and implementation of planned tree-growing restoration support programs and related policies in Cameroon and other countries.</p>","PeriodicalId":48983,"journal":{"name":"Small-Scale Forestry","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140625354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The precise characterization of plantation properties is key to delivering appropriate timber assortment to markets and optimizing timber value. Our study has developed and tested dynamic and linear programming models for optimizing the tree bucking of eucalyptus trees. To achieve this, tree taper curves for use in volumetric models were defined for optimization. Our results indicate that both the tree spacing and the increment of diameter of breast height are significant factors when estimating profitability. The income would be significantly higher if bucking timber in different assortments were used, instead of the current approach of selling as bulk based on mass.

However, scarce empirical research has been conducted to determine if such a goal has been accomplished. Using data from a household survey (<i>n</i> = 330) conducted among the members of three cacao producer associations, we determined that households producing cacao in the <i>chakra</i> system are poorer and have lower land endowments than other <i>Kichwa</i> populations in the area. Cacao accounts for 42 and 19% of agricultural and total income, respectively, reflecting that, indeed, income from cacao is essential for the livelihoods of the <i>Kichwa</i> people. Multivariate analysis reveals that income from cacao is positively correlated with landholding area, but negatively correlated with the area in forest, probably reflecting that the need for monetary income encourages indigenous households to expand the area of <i>chakra</i>. The results also show that households having off-farm income and receiving social assistance are less dependent on cacao income. Overall, our findings reflect that, while an essential source of monetary income, income from cacao -alone- is not sufficient to meet household needs.

The study employed a hybrid classification technique to group the images in to LULC classes. Moreover, key informants were used to assess the drivers of LULC change and small-scale forest expansion. The results indicated that small-scale forest increased from 2.5% in 2009 to 19.4% in 2020 in Fagta Lekoma Woredas. An increment of small-scale forest from almost none to 33% was also observed in North Mecha Woredas (1987–2020). Coverage of small-scale forest increased from 0.32% in 2009 to 7.9% in 2020 in Guna Begemidir Woredas. These happened as the expense of cropland and grazing land. Unlike during 1987–2009, cropland showed continuous decline during a period of 2009 and 2020 in all study Woredas.

Such adoption is localized and adapted to suit needs and conditions of the country and reflects its specific characteristics instead of being simply copied. In this study, we examine the process of the adoption and adaptation of the forestry extension system in Japan and discuss the meaning of policy transfer across countries and the factors influencing policy development. Although the adoption of the forestry extension system was de facto a direct coercion enforced by the occupying United States (US) government in the early post-war era, in-depth analysis revealed it was a joint effort between Japanese and US foresters. The enthusiasm of foresters in charge of forestry extension enabled them to improve it into an idealized form. This first adaptation phase can be regarded as a very progressive step in view of trends indicated by a previous study. The adoption of the US model inspired and legitimized the new system. Results imply that policy development occurs at the level of the ruler, who sets the direction of the forestry extension, and the level of the practitioner, who is in charge of the extension activities in the field. Moreover, it demonstrates the importance of examining the significance and effectiveness of policy transfers and the adaptation of adopted institutions at each level. However, motivation and perception of practitioners toward their work and allowance for voluntary initiatives given to them is the key to this notion.</p>","PeriodicalId":48983,"journal":{"name":"Small-Scale Forestry","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140004170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For individuals and families who own forest land, a key driver of ownership transfer is the eventual or actual mortality of forest owners themselves. In the State of Washington as well as the US nationally, studies on forest legacy planning reveal that most forest owners want their children or grandchildren to own their forest properties after they no longer own the forest. In contrast, the same surveys also show that a majority of US forest owners acquired their forest land by purchasing the land from a non-relative. We utilize the Washington State Forestland Database to conduct a non-parametric survival analysis of how long recently inherited forest properties remain fully owned by the new owners (i.e. there is no subsequent sale associated with the property) compared to forest land that was sold. Results show that inherited parcels have a significantly lower survival probability as measured by remaining solely within the ownership of the new owner relative to parcels that were sold within an 8-year period. This study quantifies how the mode of forest transfer influences the duration of the following ownership lifecycle and indicates that stewardship efforts should be tailored for owners who have recently inherited forest lands.</p>","PeriodicalId":48983,"journal":{"name":"Small-Scale Forestry","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139508627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Producers’ experiences vary based on their type of sugaring operation, so foresters, Extension educators, and equipment suppliers can more effectively support the expansion of maple syrup production if they tailor their outreach to the needs of each type of producer. Drawing on a survey of Wisconsin maple syrup producers (<i>n</i> = 657), this study compares the motivations, confidence in forest management knowledge, interests in learning, interests in new behaviors, desire to expand, and barriers to expansion among three groups of maple syrup producers: non-commercial, small commercial, and large commercial producers. Most producers were motivated by spending time in nature, and as might be expected, commercial producers were more motivated by finances than non-commercial producers. All three groups expressed interest in forest health management. The producers most interested in expansion were those who already sell for income, who are motivated by finances, who have fewer seasons of experience, and are newer woodland owners. Key barriers to expansion included efficient sap collection and a lack of time for non-commercial and small commercial producers, while workforce availability and a lack of capital were key barriers to expansion for both groups of commercial producers.

Hardwood timber production from state-owned native forests and plantations in Queensland has decreased substantially in recent decades, increasing the hardwood timber industry’s reliance on private native forests. However, timber production opportunities from these forests are poorly understood. This study assessed the future wood supply capacity from private native forests in southern Queensland assuming alternative levels of landowner interest in management for timber production and willingness to invest in silvicultural treatment. Commercial and harvestable private native forests in southern Queensland were classified into six forest types and their spatial distributions were assessed. Potential growth rates for each forest type were estimated based on available literature and expert opinion, and their ability to supply logs to industry with and without silvicultural treatments was projected. Commercial and harvestable private native forests were found to cover an area of approximately 1.9 M ha in southern Queensland, of which spotted gum (693,000 ha) and ironbark (641,500 ha) forest types are most common. The private native forest estate is distributed over 17,665 landholdings (LotPlans), with 17% of these accounting for 66% of the commercial and harvestable resource. Most private native forests have not been actively managed for timber production and are in poor condition. Nevertheless, they presently have the potential to supply between about 150,000 and 250,000 m 3 of logs to industry per annum. Silvicultural treatments were found to have the potential to increase the mean annual increment of these forests by a factor of between two and four, indicating substantial opportunities to increase harvestable log volumes in the medium and long-term. Private native forests in southern Queensland could potentially more than compensate for the supply gap left by the declining area of state-owned native forests that are available for timber harvesting. Actual forest management performed and log volumes supplied to market will depend on the forest management decisions of thousands of individual landholders, which are influenced by their heterogeneous management objectives, the policy environment, perceptions of sovereign risk, timber markets and the long payback periods in forestry. An accommodating forest policy environment and landholder willingness to invest in forest management could maintain and potentially increase private hardwood log supply to industry, which would support farm income diversification and regional employment opportunities.","PeriodicalId":48983,"journal":{"name":"Small-Scale Forestry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135042964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For non-industrial private forest (NIPF) owners this leads to large losses of value, not only in economic terms but also in the form of loss of biodiversity and amenity values. Therefore, several research projects are underway to develop new silvicultural methods and other measures to reduce damage. However, a successful implementation of these will often depend on the willingness and knowledge of the forest owners. The objective of this study was, therefore, to elucidate NIPF owners’ knowledge about forest damage and their preferences regarding forest management alternatives that potentially could mitigate the damage situation. Data were collected through a questionnaire that was distributed to a random sample of 1,177 NIPF owners in northern Sweden, and the response rate was 31% ( n = 368). The results show that 19% of the NIPF owners did not know the current damage situation in their own forest. In addition, NIPF owners judged that their knowledge to identify damage themselves is quite limited, except for damage caused by moose. Regarding future management options, many were positive towards avoiding clear-cuts in suitable areas, while many were negative towards implementing alternative tree species such as larch and lodgepole pine. The study concludes that there is a clear need to inform and educate NIPF owners about forest damage, but also that there will be challenges in reaching all types of owners.","PeriodicalId":48983,"journal":{"name":"Small-Scale Forestry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135773756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
