Special Issue Information

Dear Colleagues,

Plants are an important component of forests, and vegetation restoration is an important means of enhancing forest ecological functions. At the same time, the cycling of elements in forests is closely related to the interaction between plants and the environment, such as plant growth and carbon cycling. Although vegetation restoration is considered an important strategy for forest protection, attention to the process, the mechanisms, and the evaluation of vegetation restoration need to be strengthened. This Special Issue plans to give an overview of the most recent advances in the field of vegetation restoration technology and element cycling for forest conservation. It aims to provide a theoretical basis for the restoration and enhancement of forest ecosystem functions.

Potential topics include, but are not limited to, the following:

  • The latest progress in vegetation restoration technology;
  • Vegetation restoration and forest ecological function;
  • The dynamic cycling of nutrients;
  • Plant remediation of heavy metal pollution;
  • Vegetation restoration and carbon neutrality;
  • Vegetation restoration process monitoring and effectiveness evaluation.

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.

Soil calcium is a vital component in plant growth and soil health. Earthworm activities impact metal distribution and speciation a lot by changing soil pH. Nevertheless, little is known about how ecological earthworm species, particularly in Terra Rossa soil, affect soil Ca speciation distribution. This research examined the effects of the activities of four different earthworm species (epigeic species Eisenia fetida (noted as EF), endogeic species Amynthas robustus (noted as AR) and Pontoscolex corethrurus (noted as PC), anecic species Amynthas aspergillum (noted as AA)) on Ca speciations (water-soluble (CaWs), exchangeable (CaEx), acid-soluble bound (CaAc), organic-bound (CaOr), and residual (CaRe)), soil pH, the release contents of exchangeable cations (Ca, Mg, K, and Na), total calcium (CaTotal) contents, total nitrogen (TN) contents, soil organic carbon (SOC) concentrations, cation-exchange capacity (CEC), and NIRS spectral characteristics in Terra Rossa soil for 40 days under lab conditions. In contrast to control soil, 108.3%, 158.3%, 91.7%, and 125.0% of CaWs contents in casts and 116.6%, 108.3%, 58.3% and 91.6% of CaWs in uningested soil increased significantly with the inoculation of EF, PC, AR, and AA, respectively. In addition, compared with control, for casts, the contents of exchangeable Ca, Mg, K, CEC, and available-K were significantly increased in the presence of EF, PC, AR, and AA, respectively. In the casts of EF, PC, AR, and AA, soil pH values declined by 0.72, 0.80, 0.45, and 0.60 units relative to control soil, while they decreased by 0.65, 0.84, 0.34, and 0.59 units in uningested soil. The soil inoculated with PC had higher soil pH values and CaWs contents than those with the other three earthworm species. Principal component analysis revealed significant differences in soil pH, Ca speciation, NIR spectra, and exchangeable base cation release between casts and uningested soil in treatments with EF, PC, AR, and AA inoculation. These findings expand, for the first time, to the ecological functions of earthworm species, especially for PC, demonstrating a capacity to alter soil Ca speciation, decrease soil pH, affect the exchangeable base cations’ release, and participate in and regulate the geochemical circulation processes in limestone regions.
