According to the news, Chechnya has all of the following geographic features EXC

Environmentalists have warned that the Russian Republic of Chechnya is now facing an ecological disaster. Russia’s Environmental Protection Agency says recent unregulated development as well as years of separatist warfare have destroyed Chechnya’s rich natural habitat.
    Chechnya is located deep inside the North Caucasus. It has densely forested mountain highlands as well as low-lying valleys, through which two of the North Caucasus major rivers run. Their condition, according to Oleg Mitvol the deputy director of Russia’s Environmental Protection Agency, is close to catastrophic. Speaking in Moscow on Thursday, Mr. Mitvol said there were many oil spills, the result of leaks from Chechnya’s thriving but largely makeshift and unregulated oil industry. Meanwhile Chechen doctors are charting a growing number of babies being born with genetic abnormalities as well as unexplained out breaks of mystery illness among schoolchildren. Some specialists are now suggesting the region’s environment is to blame.
