So i usually go to this place to take pictures of wild horses. It happens to be right on the rim of one of the surrounding military bases testing ground. a while back i found a dead horse in the river. it wasnt floating it was in the shallows where a wash entered. i checked it out and there was no wounds and it was a young horse. i thought it might be from colic or some other horse injury but recently new signs have been posted makeing it suspicious. its pretty fucked up that they can destroy the land like that. horses ,burros, deer, bighorn sheep, mountain lions, and a number of other animals inhabit that land. not to mention those signs are posted less than a mile from the colorado river that supplies water for all of the crops growing in the colorado river valley , not to mention Los angeles water supply. these signs line the property for miles new signs other pics. http://pissv.tripod.com/Photo/photo1.html
they should but i doubt they will and if they did it would be taking away most of the land for the animals.
seems like your best bet for action would be los angeles news papers and environmental groups...get a presentation together first. good luck and thanks for shareing the concern. the horses are beautiful. did you contact the seirra club?
