Recent reports have indicated that the 1000 remaining mountain guerrillas are evidently sodium challenged and have been raiding distant farming areas for sodium in Eucalyptus trees not available in the park. Cattle ranchers have salt blocks for cattle to lick that cost as little as $5 dollars apiece. Maybe conservation experts and the ecotourist guides bringing $400 million to see the guerrillas in Rwanda and Uganda could take in some of those 50lb salt blocks occasionally and leave them for the big apes. Amazon delivers groceries these days, maybe tourist guides should deliver some sodium blocks for the guerrillas (maybe in exchange for bananas).

Maybe some geodesic durable plastic rain umbrella hung from a tree would keep the blocks from being washed away in the rain.
