As the impact factor is provided by Clarivate / Web of Science, you can check their master journal list if a journal is actually on there:

Dear Shadrack M. Muya

I checked your list and found the following:

Journal of Advanced Biotechnology and Experimental Therapeutics https://www.bsmiab.org/jabet has no impact factor (since it is not indexed in one of Clarivate’s indices which can be as indicated by Jürgen Weippert checked here https://mjl.clarivate.com/home ) but is indexed in Scopus https://www.scopus.com/sourceid/21101023926 and is a member of DOAJ https://doaj.org/toc/2616-4760?source=%7B%22query%22%3A%7B%22bool%22%3A%7B%22must%22%3A%5B%7B%22terms%22%3A%7B%22index.issn.exact%22%3A%5B%222616-4760%22%5D%7D%7D%5D%7D%7D%2C%22size%22%3A100%2C%22sort

The Journal of Phytopharmacology https://www.phytopharmajournal.com mentions in their indexing info no misleading metrics (https://beallslist.net/misleading-metrics/ ) which is a good sign. Their NAAS indexing is comforting as well since it is a reasonably reliable indexing (https://naas.org.in/NJS/journals2024.pdf )

International Journal of Agriculture and Environmental Research https://ijaer.in is unfortunately mentioned in the stand-alone version of the Beall’s list (https://beallslist.net/standalone-journals/ ) and their indexing info is full of so-called misleading metrics (https://beallslist.net/misleading-metrics/ ), most likely a predatory journal

International Journal of Environmental Monitoring and Analysis https://www.sciencepublishinggroup.com/journal/162/home publisher SciencePG is mentioned in the Beall’s list and is a publisher with ‘issues’ see for example https://www.researchgate.net/post/Is_this_publisher-Science_Publishing_Group_USA_credible No serious indexing

International Journal of Science and Research (IJSR) https://www.ijsr.net is mentioned in the stand-alone version of the Beall’s list (https://beallslist.net/standalone-journals/ ) No serious indexing

Asian Journal of Pharmaceutical and Biological Research https://www.ajpbr.org/index.php/ajpbr their indexing info https://www.ajpbr.org/index.php/ajpbr/indexes mentions no serious indices

Journal of Biology, Agriculture and Healthcare https://www.iiste.org/Journals/index.php/JBAH at least they do not mention any misleading metric, their CrossRef membership looks legit

International Journal of Biodiversity and Conservation https://academicjournals.org/journal/IJBC mentions no misleading metrics in their indexing info https://academicjournals.org/journal/IJBC/about/abstracting-and-indexing Their Google Scolar indexing claim looks legit

American International Journal of Contemporary Research (AIJCR) http://www.aijcrnet.com/index.php/indexhas no serious indexing

Journal of Biological and Food Science Research no longer active?

Transylvanian Review of Systematical and Ecological Research https://sciendo.com/journal/TRSER a pretty good journal with quite some indices https://sciendo.com/journal/TRSER?content-tab=indexing but no impact factor or Scopus indexing

There are a number of papers published in journals with an impact factor as well:

Scientific Reports https://www.nature.com/srep/ impact factor 3.8 (and indexed in Scopus as well)

Biological Research https://biolres.biomedcentral.com impact factor 4.3 (and indexed in Scopus as well)

Forensic Science International: Genetics https://www.fsigenetics.com impact factor 3.2 (and indexed in Scopus as well)

Rangeland Ecology & Management https://www.sciencedirect.com/journal/rangeland-ecology-and-management impact factor 2.4 (and indexed in Scopus as well)

East African Agricultural and Forestry Journal https://www.tandfonline.com/journals/teaf20 was published by a trustworthy publisher (no longer active?)

Pachyderm https://pachydermjournal.org/index.php/pachyderm/index is indexed in Scopus https://www.scopus.com/sourceid/19700180845 impact factor 0.8

Journal of Insect Conservation https://link.springer.com/journal/10841 impact factor 1.9 (and indexed in Scopus)

Journal of Animal Science and Technology used to be published by Springer and nowadays https://www.ejast.org impact factor 2.7 (and indexed in Scopus)

African Journal of Ecology https://onlinelibrary.wiley.com/journal/13652028 impact factor 1.1 (and indexed in Scopus)

Conservation Genetics https://link.springer.com/journal/10592 impact factor 2.0 (and indexed in Scopus)

Hope this answers your question.

Best regards.
