Special Issue Information

Dear Colleagues,

African ecosystems comprise a wealthy repository of biodiversity with a high proportion of native and endemic plant species, which makes them biologically unique and providers of a wide range of ecosystem services. The continent has a large diversity of plant and animal life with several biodiversity hotspots. African vegetation has developed in direct response to various environmental factors such as rainfall, temperature, topography, geology, geomorphology, and soil. Other factors that influence vegetation composition and structure include fire, agriculture, mining and grazing and browsing by livestock and wildlife.

Humans in both rural and urban areas depend on vegetation for their survival and welfare. However, large parts of the natural ecosystems of the African continent are being degraded due to the growing impacts of climate change and other anthropogenic actions, as well as environmental problems. The loss of habitats and biodiversity affects wildlife, livelihoods, water supply and food security, which directly impacts human survival whilst also reducing the resilience of these sensitive ecosystems. These losses also include medicinal plants and our knowledge of their impacts on humans and wildlife.

For the conservation and preservation of these various ecosystems, it is critical that we understand and describe the interactions between the abiotic and biotic components and how they regulate the ecology of plant communities. In addition, it is important that the different plant communities are classified and described, which would provide knowledge and insight regarding their biodiversity, vegetation structure, and reaction to various management interventions. Wildlife directly affects ecosystems in terms of their structure, species composition and dispersal. It is therefore equally important that the interaction between wildlife and vegetation is studied and described.

This Special Issue, entitled “Biodiversity and Ecology of African Vegetation”, will focus on plant community classification and description, plant–wildlife interactions, biodiversity, anthropogenic influence/interactions, and indigenous knowledge systems within the African context.

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. Diversity 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Southern African grasslands with a rich flora, shaped by fire, grazing, climate and geology, as well as playing a role in carbon sequestration, are becoming more important in conservation. Fire is often used as a management tool to improve vegetation and to protect property against uncontrolled fire. We therefore attempt to determine the effect consecutive burning has on vegetation. Paired plots along firebreaks were used to collect vegetation data using the Braun-Blanquet cover abundance scale. Soil samples were also collected to determine the impact of fire on below-ground nitrogen (N) and carbon (C) stocks and ratios. The results indicate that there is no difference between the plant communities of the firebreaks and the adjacent grassland; however, there are certain species that are favoured by firebreaks and others by the adjacent grassland. There is also no difference in diversity between the firebreaks and adjacent grassland areas. Carbon and nitrogen stocks as well as C:N ratios did not differ significantly between the firebreaks and the adjacent grassland plots although trends indicate a decline in both C and N with repeated burning.
