Sonoma Valley Lions

Sonoma Valley in Northern California is looking to its neighbors in Southern California for inspiration on how to keep their mountain lion population from becoming fragmented and inbred. Fragmentation and isolation occurs when populations of mountain lions are kept apart from each other and can not physically meet up and breed. In Southern California, this has led to some birth defects and reduced fertility. Sonoma County is hoping to get ahead of this problem by building wildlife crossings before it happens. 

Wildlife crossings are essential for species diversity in California and throughout the world, anywhere where roads keep wildlife from moving to where they need to be, whether for breeding, migrating between summer and winter ranges, or just to get to more food. Humans are also protected by keeping wildlife off roads and preventing vehicle collisions.
