Regular antipoaching patrols and reforestation programs in degraded areas could potentially reduce threats to populations of endangered species and may increase suitable habitat area.

Overall, human activity and forest degradation affected the number of observed chimpanzee signs negatively. In Nigeria the chimpanzee is found in the large forests blocks of Cross River State including Cross River National Park, the Mbe. Also known as Elliot’s chimpanzee it is the most endangered of four currently recognized subspecies of chimpanzee. If we put on the normal attire of rangers, we will be taken for.

For one, they operate undercover, in plainclothes. As such, the conservationists must take certain unique precautions. Secondary forests, habitat perforation, and edge length had a significant negative effect on the occurrence of chimpanzee signs. The Nigeria-Cameroon chimpanzee Pan troglodytes ellioti, is restricted to Nigeria and SW Cameroon. Along with the endangered cross-river gorilla, Nigeria-Cameroon chimpanzee, elephants, and pangolins, the Red Dragons now call this precious forest home too. The mean encounter rate for signs of human activity was significantly higher in secondary (8.0 signs km−1) than in mature forests (0.9 signs km−1). The mean encounter rate for signs of chimpanzee activity was significantly higher in mature forests (2.3 signs km−1) than in secondary forests (0.3 signs km−1) and above 1000 m elevation (4.0 signs km−1) than below 1000 m (1.0 signs km−1). Chimpanzee density estimates ranged from 0.1 (direct observation) to 0.9 (distance sampling) individuals km−2 depending on estimation method with a mean nest group size of 7 ± 5.4 (SD).

We used a generalized linear mixed model to predict the occurrence of chimpanzees in response to edge length (measured as the perimeter of core forest patches), core area of forest patches (measured as area of forest patches beyond an edge width of 100 m), habitat perforation (measured as the perimeter of nonforested landscape within core forest patches), patch size(measured as area of forest patches), and forest cover. In addition, we georeferenced signs of chimpanzee and human activity along line transects. The Nigeria-Cameroon chimpanzee is a subspecies of the common chimpanzee which inhabits the rainforest along the border of Nigeria and Cameroon.

We derived independent estimates of the population size of the Endangered Nigeria–Cameroon chimpanzee (Pan troglodytes ellioti) in Kom-Wum Forest Reserve, Cameroon, and surrounding unprotected forest areas through 1) direct observations, 2) camera trapping, 3) distance sampling, 4) marked nest counts, and 5) standing crop nest counts. In Cameroon, these activities cause a loss of suitable primate habitat and could ultimately threaten the survival of chimpanzees (Pan troglodytes).

Increased human activities such as commodity-led deforestation, extension of agriculture, urbanization, and wildfires are major drivers of forest loss worldwide.
