Big Cats Initiative grantee Laly Lichtenfeld works with local communities in Tanzania's Tarangire ecosystem to replace traditional bomas (corrals) with "living walls" made from wire fence and rapidly growing native trees. Since installing 40 living walls that protect more than 100 separate livestock enclosures, communities have seen a dramatic decline in attacks on livestock. To date, no livestock predation has happened in villages where new living walls have been installed, with a 67 percent reduction in the number of lions killed in these communities as a result.
