Long Term Problems

Which won't go away unless they are addressed.
NNP faces some particular problems owing to it's unique position right on the edge of a major city. Two of the most significant (& urgent-because to do nothing about them will just compound their effects) are LITTER & INVASIVE PLANTS.
Litter comes in two forms- along the roads & tracks of the park & blown in from the city. It is quite incredible how visitors come into the Park & despite the signs (& the pristine look of the natural Park...) chuck their litter out of the window. This is usually the remains of what they are eating as they drive by, but can also include used condoms & other esoteric human detritus....
But the really BIG problem ,especially now when it is building for rain & swirling dry-season winds & dust devils can whip discarded litter from all over Nairobi high into the sky, is wind-borne litter settling in the Park. You can see it on trees: bright coloured plastic bags for the most part; and on distant plains, sullying the grand savannah vistas.
Plastic & rubbish matters for two reasons: it destroys the natural feel & look of the Park, which is of such intrinsic value & it is a danger to any of the grazers which might inadvertedly ingest it.
What to do about it? PICK IT UP.......but the powers that be do not & neither are there enough volunteers to do so in their abscence. Which leaves your solitary correspondent on his never-ending pick-up litter mission....
Invasive species of plants abound in & around the city, where people have introduced so many garden & ornamental species, which then compete with the natives.
Two of the most pernicious are the "death spurge" - a horrible Euphorbia sp. which exudes poison from it's roots to kill the competition whilst propagating itself in a myriad different ways , which is invading the rocky grassland adjacent to the park & Opuntia sp., the 'prickly pear', which is choking the gorges (which have a truly interesting botany themselves) on the southern boundary of the Park. This problem will only get worse if the authorities do not do something about it (ie remove the invaders by hand.........)
