Dark-sky preserve

A dark-sky preserve is an area, usually surrounding a park or International Dark-Sky Association (IDA) chooses reserve to avoid confusion with park, when using the acronyms "IDSR" (International Dark-Sky Reserve) and "IDSP" (International Dark-Sky Park).

In 1999, the first permanent preserve was established in Torrance Barrens in Ontario, Canada. Nevertheless, protection zones around observatories existed well before the creation of that preserve.

The IDA recognizes protected areas outside the United States. The Mont Mégantic Observatory in Quebec, Canada is the first such site to be recognized (in 2007) as International Dark-Sky Reserve.[1] IDA has also recognized Natural Bridges National Monument in Utah as the world's first International Dark-Sky Park.[2]

Canada has established an extensive standard for dark-sky preserves that addresses lighting within the DSP and influences from skyglow from urban areas in the region. This was based on the work of the Royal Astronomical Society of Canada. There are no other established standards for dark sky preserves. Outside Canada, such designations are generally through self-proclamation. As a result, the validity of such a designation may be dubious. In some cases, dark sky preserves are neither dark nor protected.

It is generally understood that a Dark-Sky Preserve, or Dark-Sky Reserve, should be sufficiently dark to promote astronomy. However this is not always the case. The lighting protocol for a Dark-Sky Preserve is based on the sensitivity of wildlife to artificial light at night (ALAN). The lighting protocol for the RASC is based primarily on wildlife sensitivity.[3]

Some regions, like the following, are protected without any reference to an observatory or a park.

Dark-sky preserves by country


In the Canadian program, lighting within the area must be strictly controlled to minimize the impact of artificial lighting on wildlife. These guidelines are more stringent than in other countries that lack the extensive wilderness areas that still exist in Canada. The management of a Canadian DSP extends their outreach programs from the public that visit the site to include the promotion of better lighting policies in surrounding urban areas. Currently, Dark-Sky Preserves have more control over internal and external lighting than other Programs.

With the increase in regional light pollution, some observatories have actively worked with cities in their region to establish protection zones where there is controlled light pollution. These areas may not yet have been declared Dark-Sky Preserves.

Although Dark-Sky Preserve designations are generally sought by astronomers, it is clear that preserving natural darkness has positive effects on the health of nocturnal wildlife within the parks. For example, the nocturnal Black-footed ferret was reintroduced to the Grasslands National Park Dark-sky Preserve and the success of the reintroduction is enhanced by the pristine natural darkness maintained within the park by the DSP agreement.[33]
