Cesium absorption through bark of Japanese cedar (Cryptomeria japonica)

Wei Wang, Yuichi Hanai, Chisato Takenaka, Rie Tomioka, Kazuya Iizuka, and Hajime Ozawa (2016)  Journal of Forest Research 21 (5): 251–258

Wang et al. (2016) was highly evaluated by their careful and well-organized experiments which clearly showed the absorption of cesium through bark of Japanese cedar (Cryptomeria japonica), which is one of the most hot topics in the dynamics of radiocesium in forest plantation.

The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident in March 2011 has released huge amount of radiocesium (137Cs and 134Cs), and they contaminated vast area of eastern Honshu of Japan. The major part of the contaminated area is forests that have been managed for timber of Japanese cedar, oak bed logs for shiitake mushroom production, charcoal, etc. Through the intensive survey by national and local governments and many researchers, contamination level of the forests has been clarified. However, to reactivate the forest management in such areas, prediction of pollution level in future is desperately needed from the society. For the prediction of radiocesium concentration in timbers and logs, it is necessary to understand the cesium dynamics in the forest ecosystems as well as the pathway and flux of cesium inside the trees. After the initial radiocesium deposition after the accident, three potential pathways of absorption by trees are considered, i.e. from leaf surfaces, from bark surfaces, and uptake by roots. However, the contribution of these pathways and translocation in trees has not been fully understood in the previous studies after the Chernobyl accident, partly because of the initial suppression of information and lack of early studies just after the accident.

Wang et al. (2016) conducted field experiments in two sites with different level of contamination to investigate the cesium absorption from bark of mature trees of Japanese cedar. They applied stable isotope of cesium (133Cs) to the bark carefully not to contaminate the soil. The results in two sites showed the same trend which proved the absorption of cesium from the bark. They also clarified the radial translocation to heartwood through sapwood and vertical translocation to shoots at the tree top. Their methods can be applied to other tree species and will contribute largely to understand the radiocesium dynamics in forests and to control the contamination of wood products.

An overview of the science–policy interface among climate change, biodiversity, and terrestrial land use for production landscapes

Ian D. Thompson (2015)
Journal of Forest Research 20 (5): 423-429

Potential of soil seed banks in the ecological restoration of overgrazed floor vegetation in a cool-temperate old-growth damp forest in eastern Japan

Atsushi Tamura (2016)
Journal of Forest Research 21 (1): 43-56

These two original articles have great potential to influence not only to scientists and researchers but also to policy makers facing to global and local forest degradation problems: Thompson (2015) discussed the worldwide forest policies for mitigation and adaptation to climate change, and Tamura (2016) provided an evidence of the large impact of deer overgrazing on the potential of soil seed bank.

Thompson (2015) is an original article in the special issue of JFR edited by Dr. Ryo Kohsaka with selected papers from the international conference titled “Sustainable Management including the use of Traditional Knowledge in Satoyama and Other SEPLS” in 2014 sponsored by OECD-CRP (Co-operative Research Programme) co-organized by Dr. Thompson, the author, together with Dr. Kohsaka. It has marshalled the scientific knowledge on forest which is the basis of the up-to-date forest policies for mitigating the climate change and adapting to it. He says “Global progress in addressing climate change through mitigation and adaptation has been slow, although policy tools are available and most countries now have some climate change policies.” Simple mitigation policy focusing on carbon budget may mislead to conversion of natural forests into simple plantations which are low in their biodiversity and ecosystem services. Forest policies accounting biodiversity are required as it is crucial for resilience of a forest ecosystem and human society. The author proposed framework for incorporating science and local knowledge into forest policy and demonstrated possible adaptation strategies for climate change.

Tamura (2016) is the first report which showed the impact of deer overpopulation to the soil seed bank of an old-growth damp forest.  In his research field, Tanzawa mountains in eastern Japan, has suffered from overgrazing by sika deer (Cervus nippon) since 1970s, when the deer problem has not become evident in other areas.  He surveyed the potential of soil seed bank and floor vegetation both inside and outside a deer exclosure in an old-growth damp forest, which is one of the earliest deer fences in Japan, and compared it with the vegetation data taken before the deer population increased. From the results, the soil seed bank outside the exclosure has found to have little potential of floor vegetation recovery. He proposed that conservation measures (deer exclosures and deer control) must be introduced before the floor vegetation is retrogressed by overgrazing. This paper clearly showed the importance and usefulness of long-term experiments and monitoring in forest science.
