This District includes coniferous forests, productive range lands and ranches, clear streams, abundant plains game and wildlife and also it has an abundance of hard working people. A resource formula for success in a highly competitive world, hard working people and plenty of good soil> water, grass, forests and animal life. The forest (see Map 10-i) and agro-forestry resource is discussed in this section of the report since other chapters will be devoted to range land, livestock, soil and water, wildlife, people etc., their use and needs and the impact on the present and futute population of Laikipia's people. The indigenous forests of Marmanet, Al Arabel, Lariak, Rumuriti and Ewaso Narok in western Laikipia and Mukogodo forest in eastern Laikipia make up 36,000 hectares of available timber and fuelwood producing land. These lands were gazetted (set aside as National forest lands by an act of Parliament) early in Kenya's history and new play an important part in the lives of 900 forest workers and their 7,000 dependants. The Laikipia District timber resource is expected to furnish about 70,000 to 120,000 cubic metres/ annually (Laikipia, Nyandarua and the Mt. Kenya Forests) of logs to forest industries each year on a sustained yield basis and actually, with improvement and development of the saw mill industries, eventually employ 5,000 workers and support about 50,000 dependants in western and eastern Laikipia. The Laikipia population between 1980 and 1990 may nearly double so the increased forest employment will be essential to the well being of about a third of the future population of farmers - forest industry workers. •P M l/l CU CO CU > • >-i O «3« O U Pu td en O o o in XÎ rH co co co en CD CM rd LO CT> •P •P •» CTi •H O o co CO O a En CM CO co CO f» ^ co O co fd O Xt ^-^ CO 0) .Q 3 (0 co rH M co td rt! erd xni x, •P ca co CD ß *~^ eu s •p •r\ QU ^-» U CU Ë tö eu Q Ë Xi en in a O *-^ o CN X • -P u en CTl M CQ co ta »» V_*r eu CU ß eu in O u U o w r^.
