Special Issue Information

Dear Colleagues,

Carbon sequestration in soils represents an important ecosystem service with global climate impact. Most soil C resides in the boreal zone; here, soils have higher concentrations and total C stocks than in temperate and tropical forests.
The carbon sequestration capacity and the resulting climate mitigation potential of boreal ecosystems depends on many factors, where soil temperature is considered as the most important one, and many approaches and models describe this relationship in detail (e.g., the classic Q10 model). However, C sequestration is inhibited both in very dry as well as very dry conditions; a nonlinear dependence on soil moisture must be assumed. This Special Issue has a focus on the functionality of boreal forest soils along a large soil moisture gradient, from well-drained upland soils to hydromorphic soils as found in forested peatlands. Although the feedback between climate and the turnover of carbon is strongly dependent on the hydrological cycle, Earth system models (ESMs) do not reproduce these relationships well when precipitation is used to estimate carbon accumulation, presumably due to inappropriate soil moisture representations.
We are asking for contributions investigating carbon cycle–soil moisture feedback, ranging from continuous measurements of local soil climate and respiration to a range of modeling approaches at different scales.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Masson pine (Pinus massoniana Lamb) has been planted extensively in different parts of China for timber production and habitat restoration. The effects of stand age and management of these plantations on biomass, carbon storage, and soil physicochemical properties are poorly understood. In this study, we investigated biomass, carbon storage, and soil physicochemical properties of Masson pine plantations. The plantations were divided into four age groups (9, 18, 28, and 48 years), and into managed (MS) and unmanaged stands (UMS) in Hubei province, Central China. Tree biomass increased with stand age. A growth model indicated that maximum tree growth occurred when the plantations were 17 years old, and the average growth rate occurred when plantations were 23 years old. Tree biomass in managed stands was 9.75% greater than that in unmanaged ones. Total biomass carbon was estimated at 27.4, 86.0, 112.7, and 142.2 Mg ha−1, whereas soil organic carbon was 116.4, 135.0, 147.4, and 138.1 Mg ha−1 in 9-, 18-, 28-, and 48-year-old plantations, respectively. Total carbon content was 122.6 and 106.5 Mg ha−1, whereas soil organic carbon content was 104.9 and 115.4 Mg ha−1 in MS and UMS, respectively. Total carbon storage in the plantations studied averaged 143.7, 220.4, 260.1, and 280.3 Mg ha−1 in 9-,18-, 28-, and 48-year-old stands, and 227.3 and 222.4 Mg ha−1 in MS and UMS, respectively. The results of our study provide a sound basis for estimating ecosystem carbon as it relates to forest management activity and stand age. Full article
