Modeling endangered mammal species distributions and forest connectivity across the humid Upper Guinea lowland rainforest of West Africa

Abstract

Species distribution data provide critical baseline information for conservation planning and decision making. However, in many of the Earth’s most biodiverse regions, such data are lacking for many species. Here, we used ecological niche modeling and connectivity analyses to model distributions of endangered species and protected area connectivity across the Upper Guinea Forest (UGF) Global Conservation Hotspot of West Africa. We estimated the current distributions of African forest elephant Loxodonta cyclotis (Vulnerable), western chimpanzee Pan troglodytes verus (Critically Endangered), and pygmy hippopotamus Choeropsis liberiensis (Endangered) across the region and optimized connectivity in two main forest complexes in the region. We used occurrence data for the period 2010–2016 for the three species from two well-sampled national parks in Liberia (Sapo National Park and Gola National Park), and remotely sensed MODIS enhanced vegetation index data for the period 2010–2015. Our models predicted a total of 75,157 km² of suitable habitat for chimpanzees in the region, 79,400 km² for elephants, and 290,696 km² for hippos. Of these areas, for chimpanzees, 30% of the area predicted falls within the boundaries of proposed or designated protected areas, and likewise 30% for elephants, and 19% for hippos. Liberia had the largest blocks of contiguous forest suitable for these species compared to other countries in the region but this forest was largely unprotected. This study ident…

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Our understanding of pygmy hippo ecology remains limited, hindering ability to identify population cores, designate corridors and draw up management plans.

    “The difficulties in providing a coherent explanation for pygmy hippo abundance across its range highlight that our understanding of their ecology remains limited. This hinders our ability to identify important population cores, designate viable population corridors and draw up effective management plans (Freeman et al., 2019).”
  • Most geospatial variables were selected because they have been proven important to the pygmy hippo in other modelling studies, except distance to camps which represents major sources of noise and human activity.

    “Most of these were selected because they have been proven important to the pygmy hippo in other modelling studies (Bogui et al., 2016; Freeman et al., 2019; Hillers et al., 2017), except for 'distance to camps ' , which was included because it represents major sources of noise and human activity in our study area.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
