grassland corridor

The two habitat areas in question that soon will need a corridor is a large grassland area that supports five herds of antelopes. Each herd has approximately 30 to forty antelope (Bovidae antilopinae). The grassland is soon going to be split in the middle by a new freeway system running through virtually the center of this thirty thousand acre grassland. In addition to the antelope there is a group of wolves (canus lupus lupus) and annual herd of cattle (Bos primigenius).
There are ten long established watering holes on the preserve. After the freeway construction six of these will be on the north side and four on the south. All three of these species rely on the watering holes year round. The availability of the water is not a concern, the concern is that if there is no corridor to join the two areas then the grassland will very likely be too small to support the herds of antelope and cattle which in turn will likely lead to a reduction in the number of native wolves in the area.
A proposed solution is the building of a large overpass over a shallow ravine approximately 3000 feet wide. At this time this appears to be the best solution as the ravine already has two existing animal trails in it from the herds moving from one watering area in the south to the north, it is assumed that the wolves follow the migration of the antelope herds. Building the overpass should allow safe passage for all animals and it is wide enough so that the animals should not feel entrapped by the corridor. In addition no street lights are planned anywhere on this highway but a clause is added that prevents it in the future in an area one mile before and after the corridor bridge. No building is permitted within 3 miles of the corridor bridge as well. The houses that are on the southern edge of the preserve already have a no street light policy in effect and is a policy that will be continued in part due to the observatory several miles away.
The only current concern in the corridor area is illegal ohv use and entry, which will hopefully be stopped by regular patrols once a week and blocking of current entry areas.
