While a large sum of timber stock in private forests, especially broadleaved forests, has been ignored by their owners, a rising global concern about climate change and ecosystems has led to a renewed interest in natural broadleaved forest management strategies. This study establishes the forest growth model for the natural broadleaved forest of Gangwon-do based on the matrix model developed by...
Tree species composition was important for carbon storage within the same climate range. To quantify the dynamics of ecosystem carbon allocation as affected by different tree species, we measured the above- and below-ground biomass accumulation in 22 years, as well as the tissue carbon concentrations of trees in Cunninghamia lanceolata plantation and Michelia macclurei plantation. Results indic...
This study, based on different investigative documents and analytical methods, elucidates spatial distribution of habitats for major invasive exotic plants, Leucaena leucocephala, in Taiwan. Results show that Leucaena leucocephala is most harmful to broadleaved trees and its invasion directly relates to changes in the physical environment. Leucaena leucocephala can bloom and bear fruits all yea...
Integrating multimodal remote sensing data can optimize the mapping accuracy of individual trees. Yet, one issue that is not trivial but generally overlooked in previous studies spatial mismatch trees between datasets, especially different imaging modalities. These offset errors same tree on have been geometrically corrected lead to substantial inaccuracies applications. In this study, we propo...
Competition and climate influence in the basal area increment models for Mediterranean mixed forests
Competition plays a key role controlling tree growth in mixed forests. Contrary to monocultures, quantifying species mixing influence on suppose challenge since the presence of two or more requires estimate degree intra- and inter-specific competition among trees. Moreover, it is well known that aridity can also growth, especially Mediterranean Basin. In present context climate change, essentia...
Global warming has shifted climate zones poleward or upward. However, understanding the responses and mechanism of microbial community structure and functions relevant to natural climate zone succession is challenged by the high complexity of microbial communities. Here, we examined soil microbial community in three broadleaved forests located in the Wulu Mountain (WLM, temperate climate), Funi...
Typhoons are having an increasingly severe and widespread impact on forest ecosystems around the world due to climate change. However, few studies have examined impacts of strong typhoons subtropical evergreen broadleaved forests, particularly in rare old-growth forests. Here, using a 20 ha permanent plot Guangdong Province, southern China, super Typhoon Mangkhut secondary forests was quantitat...
The epidemic of mass mortality of oak trees by Japanese oak wilt has affected secondary deciduous broadleaved forests that have been used as coppices in Japan. The dieback of oak trees formed gaps in the crown that would be expected to enhance the regeneration of shade-intolerant pioneer species. However, foraging by sika deer Cervus nippon has also affected forest vegetation, and the compound ...
