Most of the National Parks have not yet reached a level of self reliant or financing themselves. Therefore, they depend on extra funds from the governments of full finance the budgets of the parks.
Conservativeness in one way or another – National parks protect the historic buildings in which America’s history was made, places like Independence Hall, Ellis Island, and the San Antonio Missions. But some of these hallowed edifices are crumbling and in desperate need of repair. They’re a big part of a $9.5 billion maintenance backlog that plagues the park system. “We need to preserve and maintain those buildings because the stories are written in the stone and the bricks,” NPCA’s Nations says.
Management of wildlife:
The iconic species protected inside the parks don’t recognize boundaries and must often move in and out of the parks to feed, mate, or migrate. If larger ecological wildlife corridors can’t be maintained to include the lands outside of parks, many species may not survive within them either. In some countries where illegal hunting law is weak, poachers encroaches the parks and kill animals and birds. High population pressure in many countries has also destructed wildlife management because people are still increasingly encroaching the parks for settlement, mining among others.
Out break of infectious diseases like Ebola, Flu, and Tuberculosis among others – such infectious diseases attack and kill animals. In some countries like Democratic Republic of Congo, most of the wild animals including primates are killed for meat/ food.
National parks are inviting places, especially for non-native species that can cause havoc once they move in. Plants and insects often hitchhike to our shores on boats or airplanes while other species, like snakes, are intentionally imported for the exotic pet trade. When turned loose with no competition, invasive species can run amok in an ecosystem and send a park’s native residents toward extinction.
Adjacent Developments to the parks:
The development of oil refineries, mines among others have destructed the smooth running of tourism activities in the parks. Such developments leads to the clearing/ cutting or destruction of wild life habitats like forest, bushes, swamps, drainage features, relief features among others. What happens on a park’s borders can dramatically impact the environment inside the park itself. Mining, petroleum prospecting, clear-cut lumbering, and other developments are generally prohibited inside parks—but they still pose serious threats to water quality, clean air, and other vital aspects of the park environment.
Climatic Changes and Natural calamities:
If Earth’s climate continues to change as scientists predict it will, the national parks will be impacted like the rest of the planet. Glaciers may melt away, as indeed they are at Glacier National Park in Montana, Mountain Rwenzori, and Mountain Kirimanjaro and so on. Fire out break, earth quakes, floods, strong winds, rain storms among others are all a liability to the tourism sector.
Shortage of Water and pasture:
Some parks are already feeling drier these days, as increasing human demand shrinks supplies on which aquatic species depend. In Florida’s Biscayne National Park, where freshwater arrives from the highly compromised Everglades ecosystem upstream, a freshwater shortage is becoming an issue even though 95 percent of the park remains covered with seawater. In Uganda, Kidepo Valley National park remain with few water sources in dry seasons which affects the wild animals and birds – it can force some animals to cross the reserved boundaries to search for water and pasture.
Air Pollution – mostly industrial pollution
The growing global industrialization in countries like china, India, United States of America among others. Great Smoky Mountains National Park in the Southeast wasn’t named for its smoke, but it is one of many parks seriously affected by the problem. Air quality issues originate outside the parks. At Great Smoky, power plant and industrial emissions are blown by winds to the southern Appalachians and trapped there by the mountains.
Some National Parks are situated in far deep and remote areas. In such areas, there are very poor roads which make them inaccessible. In some poor countries, you can hardly find 4 wheel drive vehicles which can maneuver the bad roads to National parks. National parks are the destination of many a great American road trip. But too many roads within the parks themselves are in disrepair and some pose a real danger to drivers. The same goes for many parts of the parks’ transportation infrastructure, from shuttle buses to hiking trails.
For instance in Uganda, the road to Kidepo Valley National park (One of the best in Africa) is impassable and requires a 4wd vehicle. Also roads to Bwindi Impenetrable National Park is very bad and impassable especially in rainy season, you need a 4×4 vehicle to the get to the park. This park is famous for mountain gorilla tracking experience with half the world’s remaining population of the endangered mountain gorillas.
Salonga National Park in DR Congo, is the biggest in Africa with huge species of animals and birds but inaccessible due to unavailability of roads.
