The Bats of Kenya Project
Straddling the equator in East Africa, Kenya is an economically impoverished but megadiverse country. Many challenges confront its national development, among them a burgeoning human population, persistent drought and climate change, and a too-small cadre of scientists and resource managers. Since 1998, The Field Museum has collaborated with two Kenyan scientific agencies--Kenya Wildlife Service (KWS) and the National Museums of Kenya (NMK)--to solve the nation's scientific challenges and train personnel. One of these challenges is the management of Kenya's native bat populations. Bats represent fully one-quarter of Kenya's >400 mammal species. Scientists are only now realizing the important ecological services provided by bats. In addition to maintaining healthy ecosystems through pollination of flowers, seed dispersal, and consuming herbivorous insects, bats are crucial -- if usually overlooked -- partners in modern agriculture.

In August 2011, Kenyan scientist Paul Webala (now a lecturer at Karatina University College, a branch of Moi University), WKU professor Carl Dick, and I began a three-year program to survey the bats of Kenya. This work has three immediate purposes: 1) to document the distribution, status, and ecology of Kenya's rich bat fauna, 2) to give KWS insights into managing an important and economically valuable resource, and 3) to create a vouchered call library for bats in Kenya that will enable KWS and research scientists to remotely monitor bats. In the course of this work, we are expanding Dr. Webala's training in systematics and genetics to enhance his proficiency as a mentor for the next generation of Kenyan scientists. In April and May 2012, Paul and Ruth Keeru -- a technician at National Museums of Kenya -- came to Chicago for advanced training. Initially funded by the Field Museum's Council on Africa and Bud and Onnolee Trapp, the JRS Biodiversity Foundation recently awarded Webala, Patterson, and Dave Waldien (Bat Conservation International) a $90,000 grant to continue this project.

Paul and I just finished a key and identification guide to the 145 species of bats known from East Africa (Burundi, Kenya, Rwanda, Tanzania, and Uganda). The guide will be published in Fieldiana: Life Sciences in Fall 2012.
