Title Light Pollution: Assessment of Sky Glow on two Dark Sky Regions of Portugal Type Journal Article
Year 2016 Publication (up) Journal of Toxicology and Environmental Health, Part A: Current Issues Abbreviated Journal J Toxicol Environm Health
Volume 79 Issue 7 Pages 307-319
Keywords Skyglow; Portugal; Peneda-Gerês National Park; Alqueva
Abstract Artificial light at night (ALAN), producing light pollution (LP), is not a matter restricted to astronomy anymore. Light is part of modern societies and, as a consequence, the natural cycle day–night (bright–dark) has been interrupted in a large segment of the global population. There is increasing evidence that exposure to certain types of light at night and beyond threshold levels may produce hazardous effects to humans and the environment. The concept of “dark skies reserves” is a step forward in order to preserve the night sky and a means of enhancing public awareness of the problem of spread of light pollution worldwide. The aim of this study was to assess the skyglow at two sites in Portugal, the Peneda-Gerês National Park (PNPG) and the region now known as Dark Sky Alqueva Reserve. The latter site was classified as a “Starlight Tourism Destination“ by the Starlight Foundation (the first in the world to achieve this classification) following a series of night sky measurements in situ described herein. The measurements at PNPG also contributed to the new set of regulations concerning light pollution at this national park. This study presents the first in situ systematic measurements of night sky brightness, showing that at the two sites the skies are mostly in levels 3 to 4 of the Bortle 9-level scale (with level 1 being the best achievable). The results indicate that the sources of light pollution and skyglow can be attributed predominantly to contamination from nearby urban regions.

Title Indicators and standards of quality for viewing the night sky in the national parks Type Journal Article
Year 2015 Publication (up) ParkScience Abbreviated Journal ParkScience
Volume 32 Issue 1 Pages
Keywords Society; National parks; resource management; National Park Service; Acadia National Park
Abstract Night skies are increasingly recognized as an important park resource that demands more management attention. Management of night skies can be guided by a management-by-objectives framework that requires formulation of indicators and standards of quality. Two surveys were conducted at Acadia National Park to identify indicators and standards for stargazing. The first survey used an importance –performance approach and documented light pollution as an important indicator variable. The second survey used a normative approach and visual simulations to identify a range of standards of quality for light pollution. This program of research was designed to help inform management of night skies at Acadia and other parks.

Title “Astronomical Tourism”: The Astronomy and Dark Sky Program at Bryce Canyon National Park Type Journal Article
Year 2013 Publication (up) Tourism Management Perspectives Abbreviated Journal Tourism Management Perspectives
Volume 7 Issue Pages 1-15
Keywords Astronomy-related tourism; National parks; Night sky darkness; astrotourism; dark skies
Abstract Astronomical tourism represents a less-studied segment of sustainable tourism, where a dark night sky is the underlying resource. This article evaluates an astronomical tourism program, in this case at a national park with dark skies for observing. Bryce Canyon National Park (BCNP) in the southwestern United States has a well-developed astronomy program to serve visitors. The program consists of solar viewing during the day, multimedia evening programs, and night-time star gazing with telescopes. Depending on the specific measure used, it appears that up to 10% of park visitors may be involved with the formal Astronomy and Dark Sky Program and/or more informal astronomy activities. BCNP appears well positioned to take advantage of the dark sky attributes of the park and to educate visitors about the importance of maintaining and/or increasing the darkness of night skies. Potential future developments in the program may serve to further increase the number of visitors to BCNP.
