The ocelot (Leopardus pardalis) is a medium-sized cat, designated as an endangered species under the Endangered Species Act in 1982 with habitat loss, fragmentation, and loss of connectivity being the primary cause of ocelot decline. In recent decades research has shown the greatest known cause of ocelot mortality is vehicular collisions in the remaining U.S. populations of ocelots. In southern Texas, modifications were made by the Texas Department of Transportation to reduce vehicular collision risk to nearby ocelot populations. In May of 2018 construction completed on a 6.9-mile wildlife road mitigation project which included 4 new underpass structures and 1 modified culvert, 18 wildlife guards, 3 wing walls, and 6.9 miles of continuous fencing on a 4-lane divided highway. Shortly after in December 2019, construction completed on an adjacent 9-mile wildlife road mitigation project which included 8 new underpass structures and 2.3 miles of non-continuous fencing on a 2-lane road. The primary goal of the mitigation projects is to restore habitat connectivity and reduce further ocelot road moralities. Monitoring of the mitigation structures with wildlife cameras has been continuous since each construction project was completed. Two ocelot individuals have been documented using 3 underpass structures a total of 23 times. No ocelot mortalities have occurred within the mitigation area on either road since construction completion. In addition, many native wildlife species have benefitted greatly from the construction of the underpasses by crossing the roads below grade with no threat of being hit by a vehicle. There were 34 species that successfully used the underpasses with over 45,000 successful passages. The passage rates for mammals at the 13 underpasses ranged from 24% to 74% with a combined total passage rate of 57%. We evaluated the performance of all the mitigation structures to provide guidance on future road mitigation projects in Texas and elsewhere.
