Questions related to Forestry
In a recent article (by Sigl et al., DOI:10.1016/j.shpsa.2022.12.004), several sociologists analysed the evolution of soil science over the last few decades, and one of their key observations is that "While soil science was established as an academic discipline with strong links to agriculture, this link was largely lost around 1980. This led to a perceived crisis of the discipline, which has been followed by a long process of redefining its self-understanding."
In general, I think that any input from sociologists should be welcome. However, in this particular case, I am not sure their viewpoint is correct. I am old enough to remember what happened around the year 1980. I may have missed something, but I absolutely do not think that the link between soil science and agriculture was lost around 1980, as claimed, or at any time since, for that matter. Even when we emphasise environmental issues like climate change or soil contamination (in particular, to try to get funding), the focus of our work still necessarily remains on agricultural (and to a lesser extent forestry) practices, since it is difficult to envisage drastic changes in soils that are not actively managed...
I wonder how others in soil science feel about this notion that the connection of soil science with agriculture was "lost" in 1980.
What if we never knew that plant has life. What would be the difference with and without this discovery of plants as living entity in Philosophy. What may Sir Jagadish Chandra Bose conclude about chatbot.
I have a background in Forestry and business administration and this day I believe we could improve the climate by making a forestry a attractive business that could create jobs and a wealth for poor countries like Ethiopia. I want to proceed my research that could be a start up to idea to persuade the different stakeholders in the sector. Is there any body have a work and interest in this field (Forest business management, forest product marketing).
I am looking for a dataset about fuel consumption or fuel efficiency of heavy-duty trucks for hauling logistics, specific to forestry would be better. The dataset may consist of specific manufacture brands e.g. Volvo or Scania, the engine horsepower, etc.
I have searched so far this kind of dataset and found 2 papers. But the problem is I could find the link to the dataset.
 Langer, T. (2013). Heavy-Duty Vehicle Fuel Efficiency Data in the United States. ACEEE
 Wang, J, and Rakha, H. A. (2017). Fuel consumption model for heavy duty diesel trucks: Model development and testing. Journal Transportation Research Part D (55) --> this paper uses MERL dataset
If you know any other dataset, please kindly share. I would appreciate your feedbacks. Thank you.
A good book can be an important teaching aid for undergraduate and postgraduate students as well as a useful reference for professionals at all career stages.
On the topics of wildlife habitat restoration or habitat conservation, which books would you recommend and why?
Looking forward to seeing your suggestions. Links to published book reviews also encouraged.
can anyone explain what is the difference between Ph.D. in subject-specific and research specific?
(for subject-specific examples Ph.D. forestry, Ph.D. in environmental science, ecology, etc )
For research-specific Ph.D. offering in ATREE (here is our thesis/dissertation title is considered as Ph.D. subject).
In the advent of climate change, conditions suitable for local species could be significantly altered. Hence, planting characteristic tree species of the planting sites may not be feasible. There are several pieces of literature recommending the use of composite provenance in order to restore climate-resilient characteristic tree species/forests. However, the issue of outbreeding depression is a concern. So, my question is: in the advent of climate change, would it be wise to use planting material from composite provenance for forest restoration?
I am looking for suggestions about international research centers or universities involved in Papua New Guinea. The research topic should be preferably related to forestry, climate, and biodiversity.
I am looking for topics in forestry information research, there is some research in the direction of remote sensing and forest fire monitoring, is there anything else
There is a lot of demand for information about the potential of different tree species (and also other types of crops) to capture and store carbon.
Such information is critical to designing farms with a better climate footprint.
This is particularly true for agroforestry farming systems relying on one or more tree species!
However, information on this topic seems completely scattered and not synthesized.
Does such a database exist?
I am Giang from the University of Agriculture and Forestry, Hue University, Vietnam.
I would like to ask you the following questions?
There are some researchers in the Research gate whose publications have been published in the system (Link:
Please tell me some instructions for being indexed for Our Journal.
Thanks for your kind support.
I am looking forward to hearing from you soon.
So far i found these two books which use R programming to describe forest calculations.
1) Robinson and Hamann2011, "Forest Analytics With R"
2) Mehtatalo and Lappi 2020, "Biometry For Forestry And Environmental Data"
Please let me know some other books which you know.
Data are overflown nowadays with the advent of the internet and social media. Researchers are utilizing the availability of the data with Artificial Intelligence (AI) tools for their research. In Environmental Science, what are the cutting edge research areas where AI can be implemented? Especially the countries in south Asia where the latest technologies are not being practised yet as Bangladesh.
I have a question on the relationship between maximum tree height and sampling/plot area.
It is like that I have various sampling/plot size in different forest type, and tree height, DBH are measured in the plot. While I'd like to summary the maximum tree height in each forest type. Since the plot size is varied. Should I use i fixed plot size or the various plot size is OK?
Thank you in advance for your time and comment.
I am developing the single tree detection method from ALS point clouds. To test the robustness of our proposed method, I need more ALS datasets for experimental analysis. The datasets should own referenced single tree extraction results, such as the (X, Y) coordinates of the tree tops. In so doing, we can conduct quantitative analysis and make comparison. Can anyone provide me some Forestry ALS Datasets for testing single tree detection rate?
Thanks a lot.
I'm looking for the following Korean publication: Uyeki, H. & Sakata, T., 1935. Circumstance of Ulleungdo. - Bulletin of the agricultural and forestry college Suigen (= Suwon Kodung Nongnim hakkyo haksul pogo = Kouyuu Kaihou) 91, Suppl .: 31 ff. Can someone help me?
In urban studies as related to forestry and competing landscape studies, identification of relationship that exist among these urban studies
I'm looking for data (mainly related to management: growth rate, canopy size, soil and climate preferences, etc.) about tropical trees used in tropical agroforestry.
Have you ever heard about a database or a source of technical information available to agroforest managers?
That would really facilitate land management and field experiments.
As always, I am trying to use these questions to centralize information from different sources. RG questions tend to be well indexed in Google for different users. Thank you for your contributions!
Good morning.I am a graduate student in the College of Forestry, Guangxi University.I have read the article《Brittleheart as a critical feature for visual strength grading of tropical hardwood: Approach of detection》.I don’t quite understand some parts of this article. May I discuss it with you?
(1)When we characterize visible CF’s，how do we know if the CF’s are caused by brittleheart(compression failures) or Wood splitting or wind.Because I have cut some wood(very distinct,with fibre separation) to characterize CF’s,but I can’t find fibre bucking in microscope（image0012).
(2) I cut it perpendicular to the surface of the CF'S to get the longitudinal tangential section(Figure DSC08441). Is this cutting method correct?
I'm looking forward for your reply!
I'll be working on how circular economy can be implemented in the forestry sector and people dependent on those forests.
We are searching for an R package that can calculate and draw the curves for the DBH size-class structure of the forest (see figs) to decide whether the species distribution is J-shaped, L-shaped or fluctuating. Any hints would be greatly appreciated!
Dear scientists, national experts and colleagues,
can you please help me find out up-to-date information about the proportion of clear-cutting in the management of forests in European countries?
Despite many reporting and monitoring processes (FAO/UNECE FRA, Forest Europe SoE) and national forest inventory systems (NFIs), it is still largely difficult, if possible at all, to find reliable and up-to-date information about this key question: what is the proportion of clear-cutting forestry (as compared to shelter-wood, coppice and close-to-nature forest management systems) in the countries of the EU-27 or in general in the Pan-European region.
Please do suggest studies, reports, data bases, country case studies etc. that directly report on this key questions. Thanks!
Dr. Metodi Sotirov
I have just been hit by a question that looks so simple and basic yet i failed to answer myself. Can anyone help me with a list. I feel like i can connect the answer of my aptly mentioned question to a global scale of ecosystem promotion by jointly studying it with physics and forestry.
CI-110 Plant Canopy Imager gives two reading related to leaf area index (LAI) GF lai and PAR lai. Is these values are the final ones if I am trying to Effective leaf area index or do I need to do any other calculation ? if yes, then, Which values should I use as the effective leaf area index (GF lai / Par lai)? I am trying to work on lai prediction using remote sensing.
I am dealing with stands that are primarily Redwood and Douglas fir, with lesser components of several other species. While I saw one method of SDI for a single species transformed to a per acre value from the proportion that species exhibited in any given plot, I don't know how to go through the motions of calculating that. From what I've read so far, multi-species SDI for stands is not the most reliable, but I'm not too familiar with it.
Forest Education is vital for field officers of the forestry sector, so we are researching the effectiveness of forest training on forest sampling/harvest estimation and the application of GPS on logging. Can anyone recommend a Journal to publish such kind of study? I am confusing, Does this kind of study relate to the scope of forestry or education.
It is more appropriate to select a journal free of charge for publication (or minimum charge).
I am going to buy an unmanned aerial vehicle for my university for forestry applications. Since there are alot of options, I realy get confused to choose a proper model and a valid brand. Also, l want to use a 3d laser scanner and a multispectral camera. I would rather that the vehicle have gps and imu and the flight could be programmed. Please if you have personal experience, share them.
I am looking to calculate the above-ground biomass for my forest plot using the formula: volume* WD* BEF . I will appreciate if anyone can recommend a book or paper that has the wood densities of German or temperate Europe tree species.
Thank you very much.
For the purpose of restoring the quality of degraded soils, and agricultural production, I would like to know some plants, whether herbaceous, agricultural or forestry, that have some degree of resistance or tolerance to salinity.
Bulk density of a forest soil sample in a community forest created under social forestry scheme in the district of Nadia, West Bengal is obtained as 0.81 gm/ cubic centimetre, comparatively too low from the other samples of the same forest stands collected from 500 meters distance, visibly the sample is silty in nature, and the implanted trees of the said community forest are mostly of teak categories, the forest stood in the alluvial plains of the lower Gangetic deltaic set up, is the obtained value of bulk density normal for the physical nature of the soils of the forest floors?
Biomass of the two trees namely Azadirachta indica (Neem) and (Jalpai) Alaerocarpus serratus is measured which were uprooted in the last November by the ravaged cyclone Bulbul, the ratio between Above Ground Biomass (AGB) and Below Ground Biomass (BGB) of both the trees of the Tropical Dry Deciduous Forests type is about 20:1, root systems of both the trees are not at all sufficient to erect or support this relatively higher mass of stem, branch, and leaves particularly during the cyclonic storms, do the rest of the trees have the same root systems, is this low quantitative root systems responsible for the low content of Below Ground Biomass of the Tropical Dry Deciduous Forests type whereas the BGB is relatively more in the other forest floors like temperate or conifers
what is the general trend in the R:S ratio of tree species at the seedling stage? early-successional vs. late-successional which ones have big R:S ratio? i see some contradicting results published. Plus, could these trend vary with tropical and temperate tree species?
Monocultures of exotic tree species can be poor for native biodiversity and have negative impacts on hydrology as well as other environmental characters. But is the inclusion of some exotics in a (tropical) forest restoration always measurably bad for biodiversity and environment? Does anyone know any review of this question from which to draw guidance about impacts of mixing exotics with native species. Thank you.
I and Dr Ephrem Habyarimana from Bologna Agricultural research institute, Italy are editing special issue "Remote and proximal sensing for mapping in-field leaf chlorophyll content and monitoring crop growth, development, health, and yields" in Turkish journal of agriculture and forestry. Articles are warmly invited for contribution in this special issue regaring the application of remoting sensing in agriculture forestry
Forestry is one of the most significant primary activities of the world that provides employment to millions of people. However, forest resources are dwindling over time as a consequence of human destructive activities. Acquisition of land for agriculture, settlement expansion, ruthless cutting of forests for time being profits, forest fires and diseases are some of the major enemies causing rapid forest destruction. For long term benefits, it is important to take measures for sustained yield forestry. Suggestions of the researchers and experts of the subject are needed in this regard.
From environmental sciences, social sciences, engineering, forestry sciences. Also from more specific and more technical areas.
We as Research Group want to strengthen knowledge networks of bamboo!
The introduction of digitized machinery has proven to have numerous benefits in the forestry industry in terms of profit, the environment. However these advancements in technology seem to be leaving the people trailing behind. I therefore wanted to understand the impacts of these advancement on these three pillars as their advantages have already been widely studied. Are there any other social advantages that these advancements or developments may have excluding aesthetics and recreation, especially in African countries where job security is still a problem?
Forestry or agroforestry extension is an emerging discipline for determining key factors responsible for its extension or adoption by people. In ear of climate change mainly in developing country agroforestry is economic tool for adoption but it outreach is not beyond fertliser, timber, fuel and fodder. There are various studies conducted for survey and extension but no standard scale is developed for generic criteria. With respect to current scenario what is to be generic scale or parameters for forestry/ agroforestry extension?
I am working on a book chapter to write on the latest updates in forest resources in Nepal. Any suggestions will be valued. It could be social forestry, technical forestry, remote sensing etc.

I am about to finish my PhD in Forestry (Forest Biotechnology) from Forest Research Institute, India. I am looking for postdoc opportunities abroad. Which universities and specifically supervisors are worth approaching? My area of interest is the plant root system.
I planted a couple of cypresses (Cypressus sempervirens pyramidalis). They grow well, but they are rather "slim" (narrow). I intend to plant a few more (1,5 metre high); I was told that if I cut the top of the plant, it will produce stronger branches (and become wider); it will also produce a new top. Is this correct?
Big BAF is mostly used as a very fine "sieve" to sample for species richness as well as forestry volumes and other valuable forestry data. To those who are unused to it, Big BAF is something of a mystery because it seems to contain "too many points" per acre. For those of us who are interested in inventory information containing regeneration data, the closeness of Big BAF inventory data points is crucial for good statistical analysis and description of regeneration over the landscape.
Even without stem counts, a general description of regeneration for each BigBAF point may yield better regeneration data than a traditional forestry sample inventory. It is likely to be faster than a stem-count method in traditional variable plot inventory.
There are, however, sample models for traditional sample inventory which include good inventory of regeneration. Although sample points for traditional variable plot are further apart than Big BAF, They are still considered very useful in describing what is in the lands inventoried. Some of these traditional methods have been used by this participant. A comparison of those two levels of inventory may allow for a basis of decisions to determine the suitable fineness of sample proximity and choices for sample and analysis methods.
Ultimately, in a forested system or in areas with partial forest, habitat complexity and heterogeneity should be measured by the best method. The question is, is Big BAF truly better than traditional variable plot sample for that factor?
Read an review article, "Significant Remote Sensing Vegetation Indices: A Review of Developments and Applications" by Jinru Xue and Baofeng Su. Wanting to learn which vegetation index model would be used in Borneo Malaysia (tropical forestry). NDVI is always a go to, but through this paper I read that WDRVI, SAVI, RVI, etc. could be used as well. Any suggestions?
I am working on stand structure of a Forest Reserve. How do I show novelty on the research; though the vertical and horizontal stand structure of the stand in the study area have not been reported?
I am looking for studies on costs and benefits of salvage logged forests (preferrably after windthrow /-break) to compare with the effort of salvage logging with different intensities in a recent windthrow.
Which are the main agroforestry strategies for carbon sequestration? Are the crops yield and the farmers income affected by these strategies?
One of my recent researches aims at providing agricultural and forestry sectors with the Gross Primary Productivity (GPP) variable (unit: mg CO2 m-2 s-1) at spatially (< 1 km) and temporally (1 hour) high resolution. I can provide users with the GPP variable as it is, but I would like to do further processing for more useful application and more people in various fields. Why is the GPP important for you? In what format or unit do you want GPP to be? Any other suggestions or comments are welcome.
For any non-linear equations, how can we estimate the asymptotic standard error for each of the parameters (say a, b, c, d) of that equation?
Let say an equation:
Y = a/[1+b exp (-c x X] (1/d)
Can you tell me if it's possible for me to obtain the geographic data for S. spruce from the European atlas of forestry?
I look forward to hearing from you,
I am interested in documented cases where defoliation by European giypsy moth (Lymantria dispar dispar) has led to die-back of oak on larger area (preferrably Europe). There is an on-going debate whether weakened oak forests need help by combating mass infestations of gipsy moth to avoid complete defoliation. Often a combination of different stress factors with the relatively late defoliation by gipsy moth may lead to death of individual oaks the followong year because necessary resources to develop new leaves are depleted. Forest owners fear the loss of old oaks on larger scale in extreme years like 2018 and argue for combating caterpillars of gipsy moth which may also affect non-target organisms. But are these fears reasonable? How big is the impact of defoliation on oak or other tree species?
I am working on a comparative review of assisted migration in conservation and forestry applications. Unfortunately, I have found it difficult to unearth conservation AM examples for animals. Is anyone aware of any relevant studies or implemented management strategies that fit this bill? Note: I am not including translocation in this research, only assisted migrations where species are introduction to novel environments outside of their known historic range; and I am particularly interested in examples driven by climate change.
Want to get a sense of the most crucial questions w.r.t. forestry and climate change that are yet to be answered. Questions which require further research, the answers to which will put us in a better place to combat climate change (If you have many questions, you may provide 3 big questions at the most)
I am very much interested in point pattern analysis, and I can imagine many applications that are useful in science. However, I have no clue whether such spatial point pattern analyses are also applied in real workflows of forestry companies, and if not why not.
Would be great if anyone has an opinion to share.
I am interested in the contribution of root exudates in soil processes.
What is the recommended procedure to measure the magnitude of root exudates production (the quantity over a certain time)?
Is there also a method to collect and analyse the molecular / biochemical composition of these exudates?
To make the problem even harder, I am working with trees.
But still, I am interested to know how that works for smaller plants...
I am being required to plug my bore holes taken with a standard 5.15 mm increment borer per the stipulations of a specific permit I have received. The species is Pinus palustris, a very sappy conifer, and I am boring during the growing season.
I've seen people recommend plugging candle wax or beeswax. What are some other materials people use? And where do people buy the wax in the correct shape?
Forests though have unlimited role in ecological and economic front but as all nations focusing on conservation due environmental threat industrial forestry is null and void in many state policies. What is the future of Forestry you see in global economy in coming years? What will be role of professional foresters in wood raw material production if forest plantations will be limited or stopped for ecological reasons. Can we move with industrial forestry/ agroforesty/ farm forestry vis a vis green economy?
