Reverse 911 is only for dire emergencies. Try the news media and locate clubs/organizations that would care about wildlife to get the word out. Here it's a chronic problem most years, as far as wildlife not having enough access to water during drought periods. There were times in the last decade where in spite of what little I could do here supplying water containers on a daily basis, it wasn't enough. In 2008 & 2009 was the worst here. During one summer all insect forms of life disappeared entirely except for one species of beetle that lived on cactus. The lizards and all amphibeans were gone, lots of other things. Some birds survived because they could get to whatever food & water sources that I and a few others put out, a few deer because they came for food and water every day. A few squirrels survived from what was put out. The bees were gone, the wasps could get to my water, but they finally disappeared also, most likely from lack of their food, they seemed to become weaker before they were gone. Wildlife came back later, for the most part...there's some species I've never seen since.
