This outer section actually lies outside an electric elephant fence installed in 2006/7 and is now fully inhabited by local communities to the extent that there is no sign on the ground to show where the National Park begins or ends.
Several national and international conservation organisations are working with the Kenya Wildlife Service to protect the park.
The Clarke's weaver is completely endemic to the forest, while the eponymous Sokoke scops owl, Sokoke pipit, and the Amani sunbird and spotted ground thrush are found only here and in a forest fragment in Tanzania.
The park adjoins Mida Creek, a mangrove forest that is an important shorebird wintering ground, protecting species such as the Terek sandpiper and the crab plover.
The forest also has savannah elephants, African civets, as well as sokokes, baboons and vervet monkeys.
