Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources is limited.
Conservation status is a measure used in conservation biology to assess an ecoregion's degree of habitat alteration and habitat conservation. It is used to set priorities for conservation.
The great knot is a small wader. It is the largest species of the genus Calidris. They are a migratory bird which breeds in Siberia, Russia, and flies to southern Asia and Australia in the northern winter.
An ecological or environmental crisis occurs when changes to the environment of a species or population destabilizes its continued survival. Some of the important causes include:
In conservation biology, a flagship species is a species chosen to raise support for biodiversity conservation in a given place or social context. Definitions have varied, but they have tended to focus on the strategic goals and the socio-economic nature of the concept, to support the marketing of a conservation effort. The species need to be popular, to work as symbols or icons, and to stimulate people to provide money or support.
Minimum viable population (MVP) is a lower bound on the population of a species, such that it can survive in the wild. This term is commonly used in the fields of biology, ecology, and conservation biology. MVP refers to the smallest possible size at which a biological population can exist without facing extinction from natural disasters or demographic, environmental, or genetic stochasticity. The term "population" is defined as a group of interbreeding individuals in similar geographic area that undergo negligible gene flow with other groups of the species. Typically, MVP is used to refer to a wild population, but can also be used for ex situ conservation.
The SLOSS debate was a debate in ecology and conservation biology during the 1970's and 1980's as to whether a single large or several small (SLOSS) reserves were a superior means of conserving biodiversity in a fragmented habitat. Since its inception, multiple alternate theories have been proposed. There have been applications of the concept outside of the original context of habitat conservation.
In biology, a refugium is a location which supports an isolated or relict population of a once more widespread species. This isolation (allopatry) can be due to climatic changes, geography, or human activities such as deforestation and overhunting.
Charismatic megafauna are animal species that are large—in the relevant category that they represent—with symbolic value or widespread popular appeal, and are often used by environmental activists to gain public support for environmentalist goals. In this definition, animals such as penguins or bald eagles can be considered megafauna because they are among the largest animals within the local animal community, and they disproportionately affect their environment. The vast majority of charismatic megafauna species are threatened and endangered by overhunting, poaching, black market trade, climate change, habitat destruction, invasive species, and many more causes. In a 2018 study, the top twenty most popular charismatic megafauna were found to be : the tiger, lion, elephant, giraffe, leopard, giant panda, cheetah, polar bear, wolf, gorilla, chimpanzee, zebra, hippopotamus, great white shark, crocodile, dolphin, rhinoceros, brown bear, koala and blue whale.
One of the first shark species to be protected was the grey nurse shark. The biology, distribution and conservation of this species are dealt with in the following paragraphs with a main focus on Australia as it was here it first became protected.
Reserve design is the process of planning and creating a nature reserve in a way that effectively accomplishes the goal of the reserve.
The Flinders Ranges worm-lizard is a species of lizard in the Pygopodidae family endemic to the state of South Australia. The name derives from the Flinders Ranges.
Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. More than 99 percent of all species that ever lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 2 million to 1 trillion, but most estimates are around 11 million species or fewer. About 1.74 million species were databased as of 2018, and over 80 percent have not yet been described. The total amount of DNA base pairs on Earth, as a possible approximation of global biodiversity, is estimated at 5.0 x 1037, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).
The Ngel Nyaki Forest Reserve, whose site is historically known as Majang, is situated on the Mambilla Plateau in North East Nigeria, covering 46 km2. It can be reached on foot from Yelwa village past the Mayo Jigawal, from where it is less than half an hour’s walk to the upper edge of the forest. The elevation ranges from 1,400 metres (4,593 ft) to 1,600 metres (5,249 ft). Ngel Nyaki was formally gazetted a local authority Forest Reserve under Gashaka - Mambilla Native Authority Forest order of April 1969, but presently it is under the management of the Taraba State Government and the Nigerian Conservation Foundation (NCF), with the Nigerian Montane Forest Project (NMFP) as a project partner.
Moorea reed warbler is a species of songbird in the genus Acrocephalus. Formerly placed in the "Old World warbler" assemblage (Sylviidae), it is now in the newly recognized marsh warbler family Acrocephalidae. It was once considered a subspecies of the Tahiti reed warbler.
Stephens's banded snake is a species of highly venomous tree snake in the family Elapidae. The species is endemic to Australia.
Essential Biodiversity Variables (EBVs) is a putative set of parameters intended to be the minimum set of broadly agreed upon necessary and sufficient biodiversity variables for at least national to global monitoring, researching, and forecasting of biodiversity. They are being developed by an interdisciplinary group of governmental and academic research partners. The initiative aims for a harmonised global biodiversity monitoring system. EBVs would be used to inform biodiversity change indicators, such as the CBD Biodiversity Indicators for the Aichi Targets.
Important Marine Mammal Areas (IMMAs) were formulated by the joint International Union for Conservation of Nature (IUCN) Species Survival Commission / World Commission on Protected Areas, Marine Mammal Protected Areas Task Force (MMPATF)
Keo Seima Wildlife Sanctuary is a 2,926.9 km2 (1,130.1 sq mi) protected area of mixed seasonal tropical forest in eastern Cambodia, located in Mondulkiri and Kratié provinces. The area was first established as Seima Biodiversity Conservation Area in 2002, later becoming Seima Protection Forest in 2009, finally becoming Keo Seima Wildlife Sanctuary in 2016. The site is of national, regional, and global importance for a range of biodiversity, with more than 950 species recorded within the protected area. It is also the ancestral and contemporary home of a large number of the Bunong ethnic group.
The anthropause was a global reduction in modern human activity, especially travel, that occurred during the COVID-19 pandemic, particularly in March and April 2020. It was coined by a team of researchers in June 2020 in an article discussing the positive impact of the COVID-19 lockdown on wildlife and environment. The scientific journal that published the commentary, Nature Ecology and Evolution, selected the topic for the cover of its September issue, with the headline "Welcome to the anthropause". Oxford Languages highlighted the word "anthropause" in its 2020 Words of an Unprecedented Year report.
