With all due respect, perhaps I know more about this issue than you may think.

1). according to the nonpartison Charity Navigator, 77.2 cents of every dollar raised actually goes to programs of the World Wildlife Fund en masse. They have no internal differentiation of individual program efficiency internally (as in the "Save the Tigers" program.

2). While there are more captive tigers than in the wild, WWF repeatedly makes position statements asserting there should be greater regulation (and thus fewer) private-owned big cats than at present, which represents a serious decrease in the genetic diversity of the species concerned, tigers included.

3). The average tiger's territory ranges from 10-30 square miles (26-78 square kilometers). For a human to walk the periphery of such a range once a day (8-hour shift) would require him to walk at the speed of 5-15 miles per hour at average. That's to circle the periphery once every 8 hours. Humans usually walk between 1-3 miles per hour. That's nowhere near adequate protection for just ONE tiger, let alone enough animals to represent enough genetic diversity for a stable breeding population. So, using those figures, it would take somewhere near 102,400 persons to adequately patrol (in individual actions, mind, not in parties of 3-5 which would be prudent should one encounter poachers) to just protect those 3200 wild tigers for 8 hours each day. That would be 307,200 persons to patrol 24 hours a day individually, or 921,600 persons in three-man patrol parties.

Does that sound practical at all? And that's without having property right to patrol the areas inhabited in the first place.

While I agree it is worthwhile to protect wild tigers in their natural habitat it is rather impractical by way of many of the mechanisms attempted thus far by CITES regulation, WWF fundraising measures, anti-poaching patrol parties, or even legislation within the individual nations. So while the concept is a laudable goal, throwing money at an organization producing questionable results isn't exactly wise to my way of thinking.

Just from my perspective anyway.
