The second phase of this work compared the ecological relevance of the three most common fuel-wood plant species found during market survey (Parkia biglobosa, Syzygium guineense guineense, Terminalia macroptera), with the exotic Eucalyptus camaldulensis. Results are tabulated in the tables below:

Bird nest (village weaver, Ploceus cucullatus) and mammal records (Tantalus monkey, Chlorocebus tantalus) were only observed once and only on Parkia biglobosa.
