In total, it is estimated that forest cover has been reduced from 80% to 11.3% while wetlands reduced from 28.3% to 5.1%. In addition to habitat loss and fragmentation, the native Carolinian species are also being threatened by invasive species such as garlic mustard and buckthorn, and overgrazing by White-tailed deer. A list of invasive species in the Carolinian zone can be found here. These factors have contributed to the Carolinian zone becoming the most threatened region in Ontario, with over 125 species of plants and animals listed as either vulnerable, threatened or endangered by the federal or provincial governments. This is over one-third of all vulnerable, threatened or endangered species in Canada. A full list of these species can be found here. Conservation efforts Some parts of the remaining natural area in the Carolinian zone are protected in an effort to conserve the region and its unique, diverse biota. For example, today there are many protected areas including Point Pelee National Park, 21 provincial parks, and many conservation areas. Some of the best preserved areas of Canada's Carolinian forest are located in Windsor's Ojibway Prairie Complex and Rondeau Provincial Park near Morpeth, Ontario; another is the Niagara Glen Nature Reserve near Niagara Falls, Ontario. There are also organizations like the Carolinian Canada Coalition who aim to restore the region as much as possible. Carolinian forests are complex ecosystems that cannot be replicated in gardens or other small areas. The only way to preserve this unique habitat is continue to keep larger areas of land protected from development and agriculture. Other conservation efforts have included the reduction of the white-tailed deer population from their peak density of 55 deer km−2 to 7 deer km−2, between the years of 1996-2009. However, studies have found that while this helps reduce further forest damage, continued decline in the forest canopy can still occur, indicating the recovery from overgrazing by herbivores on the forest canopy is a long process without immediate results. Maintaining a lower density of white-tailed deer, while increasing the seed sources of native trees and protecting tree saplings in herbivore exclosures are all suggested ways of helping the Carolinian forest recover or at least conserve what is remaining.
