Runover rate of wildlife in the way San Onofre – maria la baja, Colombian Caribbean
The high proportion of accidents recorded for Iguana iguana during the reproductive season, which occurs during the drought, when iguanas usually cross roads in search of nesting areas, is recorded as having been hit on roads in Mexico and Venezuela. Likewise, the Leptodeira genus, as in this study, is recorded as one of the most frequently hit on roads in Venezuela.
The present study values and compares the mortality of wild fauna and its collision rate in the road that drives of San Onofre, Sucre to María la Baja, Bolívar, in dry and rainy season; with longitude of 49Km it skirts the northwest portion of Montes de María, wide area of forest dry tropical remainder of the Colombian Caribbean.
We work during 6 continuous months of October from 2014 to March of 2015, with two walk/week for a total of 48 samplings, carried out of 05:00 to 08:00 hours, with half speed of 15 km/hour. The samples were identified in situ. When comparing statistically the two season samples with the total runnings over, doesn’t exists significant difference (DS=13.213, t=0.468, df=31, p=0,642). nevertheless, in a particular way, analyzing each group regarding the climatic time significant difference exist for the birds group (DS=1.449, t=2.400, f=9, p=0.039). With 48 sessions worked one has a daily running over rate (TA) of 0.328 ind/day/km. The TA of the present study is relatively high when comparing it with that settled down in other works. The studied road requires otherwise of signaling and infrastructure that it offers protection to the wild fauna, the situation it could put in risk to many of the species that inhabit these dry forest relicts.
