O'Reilly shared a fascinating scientific report with me. The introduction reads: "Conservation managers often ban dog walking from natural areas fearing that wildlife will see dogs as potential predators and abandon their natural habitats, resulting in outcry at the restricted access to public land. Arguments are passionate on both sides and debate has remained subjective and unresolved because experimental evidence of the ecological impacts of dog walking has been lacking. Here we show that dog walking in woodland leads to a 35% reduction in bird diversity and 41% reduction in abundance, both in areas where dog walking is common and where dogs are prohibited. These results argue against access by dog walkers to sensitive conservation areas."
Point being, the mere presence of a dog in a sensitive area like Bolsa Chica can affect the natural balance, even if it is on leash.
Given that polite, reasonable sense seems to fail with a certain type of person, O'Reilly organized for me eight reasons why the rules at Bolsa Chica (and other sensitive areas) should be respected at all times.
