Current Status of Wild Gorilla Populations and Strategies for Their Conservation

  • Patrick T. Mehlman
Part of the Developments in Primatology: Progress and Prospects book series (DIPR)


Gorilla populations and their habitats throughout Africa are severely threatened and in decline. To understand and respond to this crisis, conservationists need up-to-date information on gorilla distributions, their relative population sizes, and the rates at which these populations are changing through time. Unfortunately, there are enormous gaps in our current knowledge about distribution and abundance measures for gorillas. This chapter describes and examines these gaps, discusses why they exist, and considers how they might be addressed. This chapter also reviews and compares the specific regional and local threats to wild gorillas, which, if left to continue at current trends, will substantially reduce or extirpate most wild populations within decades. Hopefully, this review will aid a new generation of field workers to plan and execute census work in the 21st century. Such census work will be critical for understanding where and how these animals are disappearing by...

The author would like to thank the efforts of Peter Walsh and John Oates, who through comprehensive and thorough reviews, substantially improved this chapter. Stuart Nixon, who with his wife, Francine Nixon, led the Maiko South Survey, also reviewed and improved this work. The author would also like to thank Tara Stoinski and Alexia Lewnes for review and commentary. Bradley Mulley kindly provided several of the maps in this work: Figures 1.1, 1.3, 1.4, and 1.8. A portion of the author's salary and all support for DFGFI fieldworkers and partners is provided by Conservation International, through USAID CARPE funding and through Conservation International's Global Conservation Fund. Further, the surveys described in this chapter, both in Maiko and in Tayna, were supported by funds from the USAID Gorilla Directive, Conservation International's Global Conservation Fund, and USAID CARPE funding from Conservation International, the Louisville Zoo, and the Thorne Foundation. This study would not have been possible without the support of the author's organization, the Dian Fossey Gorilla Fund International. The author also gratefully acknowledges the contributions of the field staff who contributed heavily to data presented in this chapter and are members of UGADEC, the Tayna Gorilla Reserve, and Maiko National Park, ICCN. The 21st century is theirs indeed.
