to reintroduce certain mega-herbivores, like the African elephant and black rhinoceros, primary ecological efforts were made to preserve mammalian species. However, by overlooking the other contributors to this environmental chain, certain plant species have been subjected to overgrazing and trampling, mostly by the elephants of the park. This overgrazing and trampling not only destroys much of the plant life, but also forces it to adapt its physiology to stimuli that are not inherent to its evolutionary progress. Some biologists argue that it is not herbivorization alone that is threatening the flora, but a number of other ecological factors including zoochory and nutrient cycling. Up to 77 species of South African endemic plant species have been listed as "vulnerable to elephant browsing." Marine protected areas The Addo Elephant National Park Marine Protected Area and Bird Island Marine Protected Area are associated with the park. Tourism In 2018 the highest visitor count in the park's 87-year history was recorded. The park received 305,510 visitors between 1 April 2017 and 31 March 2018 (up from 265,585 in the previous year). International visitors make up 55% of this number, with German, Dutch and British nationals in the majority. There is a main camp, featuring a swimming pool, restaurant, flood lit water hole and various accommodation, four other rest camps and four camps run by concessionaires. The main entrance as well as two looped tourist roads in the park are tarred while the others are graveled. There is also an additional access road through the southern block of the park feeding off the N2 highway near Colchester; it joins up with the existing tourist roads in the park.
