Strict nature reserve

Purpose

Strict nature reserves and wilderness areas are protected areas that are created and managed mainly for the purposes of research or for the protection of large, unspoiled areas of wilderness. Their primary purpose is the preservation of biodiversity and as essential reference areas for scientific work and environmental monitoring.

• IUCN category Ia strict nature reserves are generally established exclusively for scientific field work.
• IUCN category Ib wilderness areas are defined as "large unmodified or slightly modified areas, retaining their natural character and influence, without permanent or significant human habitation, which are protected and managed so as to preserve their natural condition."

Usage and intrusion are strictly controlled. As a result, strict nature reserves often form the core zones, with wilderness areas acting as a buffer zone, similar to the concept used for national parks (which are IUCN category II), but also for UNESCO World Heritage Sites.

Protected areas

Australia

Of all protected areas, two-thirds are considered strictly protected (IUCN categories I to IV), and the rest is mostly managed resources protected area (IUCN category VI). Over 43% of the protected area in Australia is publicly owned and managed by the Australian government or state and territory governments. The second-largest component of protected areas are the Indigenous Protected Areas, at over 44% and growing .

Austria

In Austria, only one area has been designated as an IUCN category I protected area:

• Urwald Rothwald (IUCN Ia) in the Wildnisgebiet Dürrenstein (Ib), Lower Austrian Eisenwurzen

British Overseas Territories

Parts of Diego Garcia and other islands in the British Indian Ocean Territory are protected as strict nature reserves.

France

Officially created in the 1950s, Integral Biological Reserves (, RBI) were dedicated to man free ecosystem evolution, on the contrary of Managed Biological reserves (, RBD) where a specific management is applied to conserve vulnerable species or threatened habitats.

Integral Biological Reserves occurs in French State Forests or City Forests and are therefore managed by the National Forests Office. In such reserves, all harvests coupe are forbidden excepted exotic species elimination or track safety works to avoid fallen tree risk to visitors (already existing tracks in or on the edge of the reserve).

At the end of 2014, there were 60 Integral Biological Reserves in French State Forests for a total area of 111082 ha and 10 in City Forests for a total of 2835 ha.

Germany

The German federal government's national strategy for biological diversity up to 2020 published in 2007 set the aim of allowing 2% of the area of Germany to develop naturally and in an undisturbed way into wilderness areas.

United States

In the U.S. wilderness areas (NWPS) are the strictest category of protected area. They are designated by law in accordance with the Wilderness Act of 1964 by the United States Congress. They must be large enough to adequately preserve their resources and may only be entered on foot, by canoe or on horseback. Limited exceptions are the extensive areas of wilderness in Alaska. There are over 800 recognised wilderness areas.

Complete List of IUCN category 1a and 1b sites

The complete list of countries (as of 2016) with IUCN category 1b sites can be found in the Management Guidelines for IUCN Category 1b (wilderness) Protected Areas. The most up-to-date resource is the Protected Planet World Database on Protected Areas, which can be searched by many filters including IUCN category levels and country.
