Just like the Tree of Ténéré (which was for a long time the most isolated tree in the world, until it was destroyed by a negligent driver), east Niger is partially isolated from the rest of the country. 
Kama ilivyo kwa Mti wa Ténéré (ambao kwa muda mrefu umekuwa mti uliojitenga kuliko mwingine wowote ule duniani, ambao kipindi fulani uliharibiwa na dereva ambaye hakuwa makini), Niger ya Magharibi kwa kiasi fulani imetengwa ukilinganisha na sehemu nyingine yoyote ya nchi hii.
