Abstract Background Performing forest inventory in the campus is one of the breakthroughs towards achieving sustainable campus. The inventory aims to determine the number of trees and calculate the stocking of carbon and biomass. This is inevitably important when the contribution of trees to the oxygen supplies as well as stocks for carbon biomass are of concern. Realising the importance of contribution of trees to the surrounding community, this study was therefore conducted. Results The study area is identified as secondary type forest with 50.1% of the strata is 60–80% canopy cover dominated by small stands. There is a total of 14 sampling plots inventoried and measured using 40 x 40m square plot sampling. 41% of the three species found comprised of rubber trees (Hevea Brasiliensis). The total number of trees estimated is 97,325 trees with the average density of 21 m2/ha and 24,146.54 Mg CO2e aboveground biomass and carbon stocking. Conclusion The study has successfully assessed the forest resources that are available in University Malaya campus. It was found that the forests in the study area fall in the category of secondary forest where stands are in the successive growing stages. Intensive sampling units with support from sufficient spatial data produced reliable estimates. This information is crucial for the reporting of forest resources that reside in an urban environment. With the new sets of data of the forest obtained from the forest inventory, UM management now have the ability to easily and accurately evaluate the composition and condition of the forest, and estimate the environmental services and aesthetic values. These are the first few steps that have been taken by UM towards improving the management of the urban forest on campus.

Abstract Performing forest inventory in the campus is one of the breakthroughs towards achieving sustainable campus. Forest inventory aided the universities in creating a holistic baseline or framework in managing, planning and monitoring the forest in the campus in pursuance of a functional urban ecosystem through sustainable practice. The inventory aims to determine the number of trees and the stocking of carbon and biomass. Accurate estimation of the forest’s number of trees and biomass carbon sinks can improve the understanding of carbon cycles and help in developing sustainable forest management. The study area is identified as secondary type forest with 50.1% of the strata is 60–80% canopy cover dominated by small stands. There is a total of 14 sampling plots inventoried and measured using 40 x 40m square plot sampling. 41% of the three species found comprised of rubber trees (Hevea Brasiliensis). The total number of trees estimated is 97,325 trees with the average density of 21 m2/ha and 24,146.54 Mg CO2e aboveground biomass and carbon stocking.

Abstract Background National forest inventory and forest monitoring systems are more important than ever considering continued global degradation of trees and forests. These systems are especially important in a country like Bangladesh, which is characterised by a large population density, climate change vulnerability and dependence on natural resources. With the aim of supporting the Government’s actions towards sustainable forest management through reliable information, the Bangladesh Forest Inventory (BFI) was designed and implemented through three components: biophysical inventory, socio-economic survey and remote sensing-based land cover mapping. This article documents the approach undertaken by the Forest Department under the Ministry of Environment, Forests and Climate Change to establish the BFI as a multipurpose, efficient, accurate and replicable national forest assessment. The design, operationalization and some key results of the process are presented. Methods The BFI takes advantage of the latest and most well-accepted technological and methodological approaches. Importantly, it was designed through a collaborative process which drew from the experience and knowledge of multiple national and international entities. Overall, 1781 field plots were visited, 6400 households were surveyed, and a national land cover map for the year 2015 was produced. Innovative technological enhancements include a semi-automated segmentation approach for developing the wall-to-wall land cover map, an object-based national land characterisation system, consistent estimates between sample-based and mapped land cover areas, use of mobile apps for tree species identification and data collection, and use of differential global positioning system for referencing plot centres. Results Seven criteria, and multiple associated indicators, were developed for monitoring progress towards sustainable forest management goals, informing management decisions, and national and international reporting needs. A wide range of biophysical and socioeconomic data were collected, and in some cases integrated, for estimating the indicators. Conclusions The BFI is a new information source tool for helping guide Bangladesh towards a sustainable future. Reliable information on the status of tree and forest resources, as well as land use, empowers evidence-based decision making across multiple stakeholders and at different levels for protecting natural resources. The integrated socio-economic data collected provides information about the interactions between people and their tree and forest resources, and the valuation of ecosystem services. The BFI is designed to be a permanent assessment of these resources, and future data collection will enable monitoring of trends against the current baseline. However, additional institutional support as well as continuation of collaboration among national partners is crucial for sustaining the BFI process in future.

Accurate and repeated forest inventory data are critical to understand forest ecosystem processes and manage forest resources. In recent years, unmanned aerial vehicle (UAV)-borne light detection and ranging (lidar) systems have demonstrated effectiveness at deriving forest inventory attributes. However, their high cost has largely prevented them from being used in large-scale forest applications. Here, we developed a very low-cost UAV lidar system that integrates a recently emerged DJI Livox MID40 laser scanner (~$600 USD) and evaluated its capability in estimating both individual tree-level (i.e., tree height) and plot-level forest inventory attributes (i.e., canopy cover, gap fraction, and leaf area index (LAI)). Moreover, a comprehensive comparison was conducted between the developed DJI Livox system and four other UAV lidar systems equipped with high-end laser scanners (i.e., RIEGL VUX-1 UAV, RIEGL miniVUX-1 UAV, HESAI Pandar40, and Velodyne Puck LITE). Using these instruments, we surveyed a coniferous forest site and a broadleaved forest site, with tree densities ranging from 500 trees/ha to 3000 trees/ha, with 52 UAV flights at different flying height and speed combinations. The developed DJI Livox MID40 system effectively captured the upper canopy structure and terrain surface information at both forest sites. The estimated individual tree height was highly correlated with field measurements (coniferous site: R2 = 0.96, root mean squared error/RMSE = 0.59 m; broadleaved site: R2 = 0.70, RMSE = 1.63 m). The plot-level estimates of canopy cover, gap fraction, and LAI corresponded well with those derived from the high-end RIEGL VUX-1 UAV system but tended to have systematic biases in areas with medium to high canopy densities. Overall, the DJI Livox MID40 system performed comparably to the RIEGL miniVUX-1 UAV, HESAI Pandar40, and Velodyne Puck LITE systems in the coniferous site and to the Velodyne Puck LITE system in the broadleaved forest. Despite its apparent weaknesses of limited sensitivity to low-intensity returns and narrow field of view, we believe that the very low-cost system developed by this study can largely broaden the potential use of UAV lidar in forest inventory applications. This study also provides guidance for the selection of the appropriate UAV lidar system and flight specifications for forest research and management.

Tanjungpura University Forest for Special Purpose located in three districts Landak Regency, Mempawah Regency and Kubu Raya Regency. Has the potential to use and process non-timber forest products. The diversity of macroscopic fungi is not yet known as one of the potential natural biological resources of significant value. So that a mushroom inventory must be carried out to identify and assess the diversity of macroscopic fungi. The method used is the survey method. Data retrieval uses a double plot sampling technique. The size of each observation plot is 5 m × 5 m as the initial reference, four plots in the peat swamp forest area with open canopy cover conditions and also four observation plots in peat swamp forest areas with canopy cover conditions are still closed. Placement of research plots in both areas was carried out purposively in locations where there were many types of macroscopic fungi. The results showed that the types of macroscopic fungi found at the study site were 24 species. 24 species were divided into 594 individuals belonging to 23 genera and 9 families. Macroscopic fungi found in open canopy cover were found in 17 species, while in closed canopy cover there were 13 species. In both types of conditions the place to grow has the same 6 types of fungi. The degree of diversity of macroscopic fungi in various conditions the peat swamp in Tanjungpura University Forest for Special Purpose is low.Keyword: Macroscopic fungi, peat swamp forest, Tanjungpura University Forest for Special Purpose.

Abstract The purpose of this study was to determine the habitat characteristics of the Sumatran Elephant in the Serbajadi District Forest. Data collection by looking at the use of habitat which is characterized by the distribution of faeces found in various habitat units in the home range of the Sumatran Elephant. The method used is observation with a track with a size of 3,600 m which is divided into 20 observation plots with a distance between plots of 100 m. The data obtained in the field were analyzed descriptively and presented in tabular form. The results of this study indicate that the Habitat Characteristics of the Sumatran Elephant in the Serbajadi District Forest chose habitat units with very dense canopy cover (>75%), moderate feed availability (26-50%), rare mineral source trees availability (< 3 trees/plot). availability of sparse scrubbing trees (<3 trees/plot), close to primary forest (0-500 m), low land elevation (0- 400 masl), gentle slope (0-20°), close to water sources (0-250m). Secondary forest/vegetation type and frequency of habitat use based on the findings of faeces that the Sumatran elephant most frequently visited was secondary forest than primary forest because the secondary forest was for feeding activities while the primary forest was used for resting and reproduction.

State and development of forests close to settlements – results from the NFI For more than 30 years, the national forest inventory (NFI) has been reporting on the state and development of the Swiss forest and its services. Here, for the first time on the topic of “urban forest”, focusing on the forests in the Swiss lowlands, where all urban centers are located. Due to missing definitions we classified the forest according to household equivalents in the vicinity of NFI plots. The forest was classified as either close to settlements (urban) or far from settlements. Using indicators, we compared both categories in order to answer the following questions: 1) How common are forests close to settlements? 2) How do forests close to settlements and far from settlements differ? 3) Is there a potential for conflict of use? 4) Which developments could be observed in relation to forest perception in the last 20 years? 29% of the forest in the lowlands is close to settlements. Five out of ten indicators on forest provision do not differ between both forest categories. Differences occur in relation to the degree of mixture and forest structure. Furthermore, close to settlement forests have more forest roads, recreational facilities and a primary “recreation” function. Regardless of their primary function, forests close to settlements are more intensively used for recreation. Following the NFI model on nature provision for recreation, the forest area with high nature provision has increased in the last 20 years, for all forests. The results indicate that both forest categories are quite similar and are managed in a similar way. Due to the intensive recreational use of lowland forests close to settlements, a certain conflict potential between recreationalists and forest owners is given, posing a challenge for forest managers.

Trees in the city provide numerous ecological, health, and social benefits to urban residents. Studies from large North American cities have confirmed a spatial pattern that higher urban forest tree canopy positively correlates with higher levels of affluence. The just distribution of trees will become increasingly important for urban planners and foresters as there is a national trend towards living in cities. This research report investigates the equity of distribution of urban tree canopy cover in two neighbourhoods on the peninsula of Halifax, Nova Scotia. High spatial resolution land cover data from 2007 and 2006 Statistics Canada census data was used to create maps and tables to answer the research question. The socio-economic indicators of median household income and population density are represented based on census tract dissemination areas from the 2006 Statistics Canada long survey. Preliminary results indicate lower median household income and higher population density in the chosen study area of North End Halifax compared to higher median household income and lower population density in the chosen study area of South End Halifax. Tree canopy cover density is slightly lower in North End Halifax (5.3%) than in South End Halifax (7.6%). These preliminary results coincide with findings of other researchers that higher household income and lower population density at the neighbourhood level may result in increased urban forest canopy. However, further research and more reliant tree canopy cover data is needed to determine the accuracy of these findings.

Purpose – тo generalize methodical approaches to the interpretation of the category of capitalization in the forestry complex and to identify sources of funds that can provide an additional financial basis for the capitalization of forest resources. Research methodology. In the context of this work, the method of system analysis and synthesis was used, as well as a comparative method, which allowed to determine the optimal approach to the identified issues. Scientific novelty. The article summarizes the existing interpretations of the concept of capitalization, according to which the main methodological approaches to it are highlighted, in particular, as: the process of attracting and increasing the value of any assets (resources); the process of transformation of factors of production (assets, resources) into capital; performance of the entity. The article forms directions and relevant additional sources of funds for the use of forest resources, which can provide an additional financial basis for the capitalization of forest resources (assets). Conclusions. It is established that today it is impossible to assess forest assets as a source of environmental and social functions, as there is no methodology for calculating their value. It is noted that the only approach to the assessment of forest resources is only the actual cost of part of forestry products, including by- products and in-use use, hunting, harvesting of secondary forest materials and, accordingly, capitalization of only part of rent in real sales prices. period of restoration and formation of forest stands. Key words: capitalization, forestry complex, forestry assets, forest rent, sources of financing.
