Common use of Distribution Surveys Clause in Contracts

Distribution Surveys. The full extent of the Cross River Gorilla’s range is still not fully known. Recent surveys in Nigeria have confirmed the presence of gorillas in an area they were thought to no longer use (Olum Hill, near Afi Mountain). In Cameroon, gorillas were thought to be present in the southern portion of Mone River Forest Reserve, but field surveys failed to produce any evidence of their presence. Also in Cameroon, a population believed to have been extirpated (Bechati-Fossimondi-Besali) was recently re-discovered. Taken together, these findings serve to emphasize the need to expand our knowledge of the gorillas’ range. Systematically conducted intensive surveys are needed to more precisely determine the full extent of the gorillas’ distribution. Intensive surveys (i.e. employing multiple teams of field workers and of three or more weeks in duration) are necessary due to the low density of gorillas typical of the region, steep terrain, and difficulties involved with detecting gorilla signs in the types of forest typical of the Cross River area. Even in areas where gorillas are known to exist it is often difficult to locate any signs of gorillas. In particular, several areas stand out as needing further survey work:
