Assessing the impact of deer on young trees in a Sugi (Cryptomeria japonica) plantation based on field signs

Hiromi Yamagawa, Fumiaki Kitahara, Tatsuya Otani, et al.

Subjects: Forest Management, Forest Sciences, Life Sciences

Predicting the level of damage caused by deer browsing in young plantations is important for selecting appropriate damage control measures. In this study, we examined a method for assessing the level of deer damage in young Sugi (Cryptomeria japonica) plantations by observing field signs of deer. First, a questionnaire survey was conducted to obtain information about the damage caused by deer [...]

A Systematic Map of Research Exploring the Ecological Modifiers and Consequences of Bark Damaging Behaviour in Squirrel Species

Alexandra Ash, Yanjie Zhao, Evelyn P. Covarrubias, et al.

Bark-stripping and browsing by mammals in woodlands can cause widespread damage to trees, inhibiting tree growth and leading to whole tree or canopy death. Sciurid species worldwide are known to incorporate inner bark or cambium tissue into their diets, and outer bark can additionally be used as nesting material. The drivers and causes of bark-stripping behaviour have been investigated and [...]

A REVIEW OF INDIA SCALE ANALYSIS OF FOREST FIRE AND TOXIC EMISSION

Alija Priyadarshini, Amit Kumar Mohapatra

Subjects: Forest Management, Forest Sciences, Life Sciences

Forest is like a backbone to live on earth. Humans are dependent on it for food, shelter, and habitat. Exponentially increasing human population is making pressure on forests and their ecosystem. Although we are greatly dependent on the forest for our day-to-day life still there is the least effort evident from the human side for its conservation. Forest fire is a natural phenomenon that occurs [...]

The Global Forest Health Crisis: A Public Good Social Dilemma in Need of International Collective Action

Geoffrey Williams, Matthew D. Ginzel, Zhao Ma, et al.

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]

Tree measurements in the urban environment: insights from traditional and digital field instruments to smartphone applications

Rocco Pace, Emanuela Masini, Diego Giuliarelli, et al.

Published: 2021-11-30
Subjects: Botany, Forest Management, Forest Sciences, Life Sciences, Plant Sciences

Urban forests can provide essential environmental and social functions if properly planned and managed. Tree inventory and measurements are a critical part of assessing and monitoring the size, growth, and health condition of urban trees. In this context, the parameters usually collected are DBH and total height, but additional data about crown dimensions (width, length, and crown projection) are [...]

Aboveground carbon stocks in Madagascar’s vanilla production landscape – exploring rehabilitation through agroforestry in the light of land-use history

Marie Rolande Soazafy, Kristina Osen, Annemarie Wurz, et al.

Published: 2021-06-28
Subjects: Agriculture, Forest Management, Forest Sciences, Life Sciences

Forests and tree-dominated land uses store large amounts of carbon stocks in plant biomass. However, anthropogenic changes in land use and land cover decrease tree cover and associated carbon stocks. Agroforestry has the potential to maintain or restore carbon in plant biomass but the amount will be influenced by various factors that may include land-use history and management practices. However, [...]

A 25-years population dynamics of sika deer in Kyushu Island, Japan: Estimation using vector autoregressive spatiotemporal model and evaluation of a large-scale management

Kei Suzuki, Yasumitsu Kuwano, Yuki Kanamori, et al.

Published: 2021-02-04
Subjects: Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Population Biology

Regional management of large herbivore populations is known to be effective in reducing local economic damages and conserving local endemic plants. However, herbivores often move across management areas, and the effect of population management on a large spatial scale is poorly understood, even though it is necessary to use a large-scale approach across multiple management units to implement [...]

Hardwood content impacts the parasitoid community associated with Eastern spruce budworm (Lepidoptera: Tortricidae)

Christopher J. Greyson-Gaito, Sarah J. Dolson, Glen Forbes, et al.

Published: 2021-01-12
Subjects: Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences

A major pest of eastern North American forests is spruce budworm, Choristoneura fumiferana Clemens (Lepidoptera: Tortricidae), which outbreaks every 30–40 years and causes large scale tree mortality. Researchers have established that hardwood content reduces the defoliation and mortality of balsam fir and spruces during spruce budworm outbreaks. One mechanism posited to explain these patterns is [...]

Do forest fuel reduction treatments confer resistance to beetle infestation and drought mortality?

Zachary Steel, Marissa Goodwin, Marc Meyer, et al.

Subjects: Ecology and Evolutionary Biology, Forest Biology, Forest Management, Forest Sciences, Life Sciences

Climate change is amplifying the frequency and severity of droughts and wildfires in many forests. In the western U.S., fuels reduction treatments, both mechanical and prescribed fire, are widely used to increase resilience to wildfire but their effect on resistance to drought and beetle mortality is not as well understood. We followed more than 10,000 mapped and tagged trees in a mixed-conifer [...]

Timber harvest and tree size near nests explains variation in nest site occupancy but not productivity in northern goshawks (Accipiter gentilis)

Sabrina Rodriguez, Patricia L. Kennedy, Timothy H Parker

Published: 2018-12-10
Subjects: Animal Sciences, Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Ornithology

Conservation concern for the northern goshawk (Accipiter gentilis) reflects evidence that goshawks may abandon nest sites or suffer from reduced nesting success in response to some forms of timber harvest. However, this evidence is mixed and has yet to be reviewed systemically and quantitatively. Therefore, we conducted a meta-analysis to assess the extent to which timber harvest and tree size [...]
