Protected areas in Tanzania (Hifadhi za Mali hai za Tanzania, in Swahili) are extremely varied, ranging from sea habitats over grasslands to the top of the Kilimanjaro, the tallest mountain in Africa. About a third of the country's total area is protected to a certain degree as a national park, game reserve, marine park, forest reserve or the like. 840 protected areas are spread across 7,330 km² of ocean and 361,594 km² of land in Tanzania. The coastal and marine areas are less protected than terrestrial ecosystems, which are given the highest level of protection. Tanzania is one of the world's major biodiversity hotspots thanks to its vast national parks, "the Eastern Arc" mountains, wetlands, coastal forests, marine, and freshwater systems as remarkable reservoirs of plant and animal species. A wide range of endemic species of birds, reptiles, snakes, amphibians, wild coffee variations, and the well-known African violet flower can also be found in Tanzania.^[1]

The world's most stunning annual migration of large mammals takes place in the Ngorongoro Conservation Area and Serengeti National Park, both of which are Biosphere Reserves and World Heritage Sites. They travel through one of the country's major forest ecosystems, the Acacia-Commiphora woodlands and associated wide-open grasslands of Serengeti National Park, while in Ngorongoro Conservation Area, they travel through the upper Kitete/Selela corridor along the Great Rift Valley, which connects the area to Lake Manyara National Park and is used by elephants and buffaloes. It goes without saying that Tanzania's wildlife corridors are under grave danger due to the severe strain from land use change. The President recently approved the creation of the River Ugalla, Kigosi, and Julius Nyerere National Parks.^[2]

Tanzania is home to portions of eight transboundary conservation areas, including the Amboseli-Kilimanjaro-Longido, Kagera, Mnazi BayQuirimbas, Niassa, Serengeti-Mara, Tanga Marine Reserves System, Tanga Coelacanth Marine Park, Diani Chale, Kisitee-Mpunguti, and Western Indian Ocean Transfrontier Marine Park.^[3]

Tanzania is one of the 15 countries with the largest percentage of endemic and threatened species worldwide, with at least 14,500 known and confirmed species. Tanzania also has a wide variety of species. In terms of bird species, it makes up more than a third of all plant species in Africa and is the 12th most abundant in the world. 20% of Africa's population of large mammals reside in the nation. More over half (54%) of the species that are present in the nation are plant species. Notably, more than 25% of all plant species are employed as therapeutic plants that can be gathered from the wild.^[4]

Unknown is the precise number of endemic species in the nation. However, the evidence that is now available suggests that there are between 400 and 3,000 different indigenous species. The Black Rhino (Diceros bicornis) and elephants (Loxodonta africana), which are threatened owing to poaching, are two species of concern based on the analysis of threatened species in the nation, taking into account ecological, economic, and social value. Pan troglodytes, colobus monkeys (Procolobus gordonorum and Procolobus kirkii), mangabey monkeys (Rungwecebus kipunji, Cercocebus sanjei), leopards (Panthera pardus), cheetahs (Acinonyx jubatus), and African wild dogs (Lycaon pictus) are some other keystone species of critical importance. The biggest lion (Panthera leo) population in the world is found in Tanzania. Additionally, there are species of high-value timber, such as Afzelia spp., Pterocarpus spp., and Diospyros mespiliformis. There are also significant marine species, such as tuna, dugongs, and marine turtles, as well as prawns (Metapenaeus monocerus, Penaeus indicus, and P. monodon).^[5]

The following list gives an overview on the various protected areas in Tanzania including their predominant habitat, wildlife and flora. Especially remarkable species (endemics or those occurring in unusually large numbers) are set in bold.

Twenty three national parks together comprise an area of more than 99,306.5 square kilometres (38,342.5 sq mi). They are administered by the Tanzania National Parks Authority (TANAPA). Names like Arusha and Serengeti are well known, partly due to films about African wildlife.^[6]

Nature Forest Reserves (NFRs) are a designation under the National Forest Act of Tanzania which offers the highest level of protection. NFRs are state-owned and are managed by the Tanzania Forest Services (TFS) Agency. No extraction of timber or animals is permitted in forest nature reserves, and activities are generally restricted to research, education, and nature-based tourism.^[14]

Tanzania's biodiversity is under threat from a variety of natural and human factors, similar to other nations. Overexploitation of plant and animal species, the introduction of non-native species, pollution, and climate change are the greatest threats to biodiversity in Tanzania. Another issue is habitat loss and degradation brought on by conversion to other land uses, such as urbanisation, agriculture, and grazing.^[15]

Loss of biodiversity in water systems is caused by human activities such as poaching, deforestation, bottom trawling in the oceans, unsustainable fishing methods, damming and dredging of streams, rivers, and lakes, and draining and degrading of wetlands, estuaries, and mangroves. Economic expansion, population increase, poverty, the international commerce in plant and animal species, and climate change are all combined to form this activity.^[16] Deforestation, coral bleaching, habitat loss through fires, unplanned land use, uncontrolled resource exploitation, an increase in the trade in bush meat, and the construction of roads and other infrastructures are all severe risks to ecosystems. One such habitat type that is under great pressure to change into other land forms is wildlife corridors.^[17]

Mangrove, coral, dynamite fishing, and illegal fishnet use pose serious threats to habitats in marine ecosystems, while eutrophication and pollution caused by decreased precipitation and increased evaporation, overfishing, illegal fishing, the introduction of exotic fish and species, particularly Nile perch and water hyacinth, and declining water levels pose serious threats to habitats in inland water ecosystems.^[18]

Unsustainable animal species exploitation puts enormous pressure on habitats in terrestrial ecosystems. Larger carnivores like lions, leopards, cheetahs, and wild dogs as well as populations of elephants, giraffes, zebras, buffaloes (Syncerus caffer), antelopes, wildebeest (Connochaetus taurinus), and black rhinos (Diceros bicornis) are among the key species that are under pressure.^[19]
