Overlove is exactly it. However, it isn't just the trash from campers or the impact from hikers... The biggest impact you see out there is summed up with one word: development. Building housing blocks, roads, resorts and commercial developments on the slopes of the mountains has dramatically reduced the amount of habitat available and has nearly totally cut-off migration routes and home ranges for animals that need more room than one mountain range can provide (big horn sheep being the most obvious causalty in this range). The loss of habitat is even greater when you consider how far away from these developments you have to get before flora and fauna are no longer impacted by their presence. People think that when you build a house in the foothills, you're only impacting the .3 acres of land that you develop, but you don't realize that this pushes the boundary of the natural world back many thousands of feet beyond your back gate. Sure, you've got a great view, and bunnies and quail in your front yard every morning. But at what price?
Sprawl up the foothills and between the Tortalitas and the Catalinas is eliminating mountain lion habitat and mobility - and when the apex predators disappear, the whole ecosystem begins to fall apart...
