Pest Infestation of Dipterocarpus retusus (Blume) Fruit at Different Heights in KPHP BATULANTEH

Keruing gunung (Dipterocarpus retusus) is a non-timber forest product (NTFP) as a fruit producer that can be used as raw material for vegetable fats. One of the problems faced in planting programs for both production and conservation forests is the presence of fruit pests. The purpose of this study was to determine the fruit pests infestation fruits of D. retusus and the effect of altitude on fruit size and weight in Batulanteh Sumbawa. Fruit samples were collected at locations with different heights, namely below 1000 masl (T 22ºC, RH 83%) and above 1000 masl (T 20ºC, RH 88%). The samples of invading pests were observed and measured morphometry and morphology. The results showed that the insect infestation on the fruit was Alcidodes crassus. The percentage of fruit severity level reached more than 50% at each location. Elevation has a significant effect on fruit diameter and fruit weight, both infested by pests and whole fruit.

Native palms as an economically important non-timber forest product among rural communities in the Yucatán peninsula, Mexico

Objective. To analyze the valuation, use, and preservation of native palms as a non-timber forest product (NTFP) of high economic importance for rural communities in the Yucatán Peninsula, Mexico. Design/methodology/approach: The available literature on palms and their use in the Yucatán Peninsula (YP) was examined using the snowball method. Subsequently, different online flora databases were consulted in order to examine the taxonomic identities of palm species present in the YP. The reported uses were classified. Results: The YP has 20 native species that belong to 13 genera and three subfamilies. All of them are economically exploited as NTFPs, especially in construction (85%) and honey production (70%), followed by food and medicinal use (35% each), craftwork (30%), ornamental use (25%), and fodder (10%). These data confirm that native palms are an important livelihood means for the inhabitants of Mayan communities in the region. Study limitations/implications: The research faced a limited database of encyclopedias, anthologies, directories, books, or articles that interpret works or research about this topic. Findings/Conclusions: The local and regional use of palms represents an additional income for the people who use this natural resource on different productive scales, both in rural communities and city centers. An alternative to ensure the sustainability of palms would be to establish governmental programs for their reproduction

The Impact of the COVID-19 Pandemic on Consumers’ Preferences for Wood Furniture: An Accounting Perspective

The COVID-19 pandemic has had a major impact on forest product markets and the forest product industry, and has also seriously affected the sales of forest products. This research aimed to analyze people’s preference for wood furniture and make policy recommendations. We examined the impact of the pandemic on consumers’ preferences for wood furniture from the perspective of accounting. Taking the accounting data of wood furniture enterprises as the research object, through the translog revenue function, and using the relationship between revenue and consumption in economics, we found that the COVID-19 pandemic has reduced consumers’ preferences for wood furniture, but the decline in preference is smaller for wood furniture produced by extra-large furniture manufacturers. This study contributes to the literature and in view of our research results and the severity of the COVID-19 pandemic, we provide policy suggestions for the related governmental agencies and wood furniture manufacturers, in this special environment, that can reduce the negative impact of a pandemic on the wood furniture industry.

Community-based forest management in the forest District of Kediri: cultivation of pineapple and turmeric under forest stands

Community-based forest management (CBFM) is a forest management system that is carried out by communities and forest companies with a mutual benefit principle.One of them is to bring benefits to the community from the plants cultivated. Each combination of plants yields a different income.The research aims (a) to calculate the profit of pineapple and turmeric cultivation under forest stands in the Forest District of Kediri, (b) to calculate the profit sharing between communities and companies, and (c) the value of forest product fees of pineapple and turmeric. Data were collected through observation and interviews and employ benefit-cost analysis. Shared profit was calculated based on cooperation agreements and the fee was calculated based on the prevailing tariff. The results of the study showed (1) the profit of the pineapple business was IDR 18,800,000 per ha per season, of which IDR 12,635,000 was for the community, IDR 5,415,000 was for the company’s profit share IDR 750,000 was for forest product fees. (2) the profit of the turmeric business was IDR 13.600.000 per ha per season, of which IDR 9,205,000 was for the community, IDR 3,945,000 was for the company profit share, and IDR 450,000 was for forest product fees.

Population Structure, Growth Dynamics, Leaf Production and Soil Conditions of Megaphrynium macrostachyum, a Key Non-Wood Forest Product in Central Africa

Aims: Megaphrynium macrostachyum is a key non-wood forest product (NWFP) in Central Africa. This study aims to describe the soil characteristics and behaviour of the species Megaphrynium macrostachyum in a fallow land in southeastern Gabon. Methodology: Leaf growth was monitored weekly on a sample of 60 leaves for 10 weeks, after the unrolling of horns. Population structure and leaf production were quantified on 64 m² plots and then extrapolated to the hectare. Soil samples were collected at 30 cm depth. Results: Leaf growth and stem enlargement were observed to take place during the horn stage, while stem elongation became active after this stage. The stem reached its maximum height about 60 days after the leaf had fully unrolled. Within the same population, leaf length and leaf width were less heterogeneous (on average 55.6 ± 5.9 cm and 35.5 ± 4.5 cm, respectively); whereas leaf area, stem diameter and stem height were quite heterogeneous (on average 1475 ± 328.3 cm², 9 ± 2.2 mm and 154 ± 33.3 cm, respectively). Megaphrynium macrostachyum was observed to colonise its environment quite well (148,646 ± 66,623 stems per hectare), thus explaining its high leaf production (104,167 ± 45,271 usable leaves per hectare). The soil sample analysed revealed Megaphrynium macrostachyum to grow in sandy-silty or sandy-silty-clay soils (58.21% sand, 25.69% silt and 16.1% clay), and in soils that are wet (35% relative humidity), acidic (pH 4.01), low in phosphorus (9.38 ppm assimilable phosphorus) and total nitrogen (0.01% total nitrogen), and high in organic matter (19.3% organic matter). Conclusion: The leaf area exploited by local populations is variable. Megaphrynium macrostachyum is less demanding on soil characteristics, with high leaf production. From a cultivation perspective, the horn stage would be decisive.
