Abstract |
Barriers to animal movement can isolate populations, impacting their genetic diversity, susceptibility to disease, and access to resources. Barriers to movement may be caused by artificial light, which is known to disrupt bird, sea turtle, and bat behavior, but few studies have experimentally investigated the effects of artificial light on movement for a suite of terrestrial vertebrates. Therefore, we studied the effect of ecological light pollution on animal usage of a bridge under-road passage structure. On a weekly basis, sections of the structure were subjected to different light treatments including no light added, followed by a Reference period when lights were off in all the structure sections. Sand track data revealed use by 23 mammals, birds, reptiles and amphibians, nine of which had > 30 tracks for species-level analysis. Columbia black-tailed deer (Odocoileus hemionus columbianus) traversed under unlit bridge sections much less when neighboring sections were lit compared to when none were, suggesting avoidance due to any nearby presence of artificial light. Similarly, deer mouse (Peromyscus maniculatus) and opossum (Didelphis virginiana) track paths were less frequent in the lit sections than the ambient. Crossing was correlated with temporal or spatial factors but not light for three of the other species. These findings suggest that artificial light may be reducing habitat connectivity for some species though not providing a strong barrier for others. Such information is needed to inform mitigation of habitat fragmentation in the face of expanding urbanization. |

Abstract |
The use of security lighting that emits spill light is considered a cause of light trespass problems in the residential areas. Therefore, a cutoff panel was installed as an alternative way to reduce light trespass. On the other hand, it has another problem in that it is less effective and is not good enough for aesthetics and safety. In this study, a light cutoff panel was designed and manufactured to reduce the light trespass, and the structure of a proper light cutoff panel was studied. Using a goniophotometer, the light distribution file (IES file) was extracted and the characteristics of light distribution were analyzed using the RELUX program. The results showed that the reduction of spilt light in the backward direction was decreased significantly for all types of light cutoff panels except the coated globe. In the case of a black powder coated light cutoff panel, the forward light caused by light reflected from the surface of the light cutoff panel was also reduced, which means that the black powder coated light cutoff panel is effective in the performance of light cutoff in the forward and backward directions. In addition, the coated glove increased the spilt light in the forward and backward directions because it reflects the upward light to go down. A 90 % accuracy between the measurement value of light trespass and the expected value of the light trespass was obtained from a simulation. |

Abstract |
Acadia National Park is among the most visited national parks in the United States, attracting millions of people per year. Thousands of those visitors come to the park for “astro-tourism,” as Acadia has become one of the premier stargazing locations on the east coast. There remains, however, the continued threat from light pollution from the surrounding communities that negatively affects Acadia's darkness, contributing to a lesser visitor experience and potentially harming native ecosystems. Although park management and community organizations have engaged in significant efforts to decrease Acadia's nighttime light levels and raise awareness among visitors and locals regarding the importance of darkness, the park still seek to continue to decrease light pollution. This report developed policy options that could help solve the long-term policy goal of decreasing nighttime lighting levels within and around Acadia while also using the International Dark-Sky Association's Dark-Sky Park designation requirements as a reasonable, short-term policy benchmark.
Working within existing organizations, the policy options crafted to address Acadia’s nighttime lighting levels were analyzed both qualitatively through a criteria evaluation and quantitatively through a Benefit Cost Analysis.
The options included 1) the formation of a Darkness Coalition within the League of Towns, 2) a reimagining of the Worcester Polytechnic Institute Dark-Sky Project into the Dark-Sky Taskforce, 3) the creation of a Lighting Consultant position paid through the Friends of Acadia Wild Acadia initiative, and 4) the combination of Coalition and the Taskforce into the League of Towns – Dark-Sky Partnership (LOT-DSP). The report recommends the adoption of Option 4 – the creation of the LOT – DSP. While this option does not provide the greatest estimated monetary net value compared to the Status Quo in the quantitative evaluation, it still provides an estimated benefit of about $105 million over the course of five years and is the strongest option in the qualitative analysis. The LOT – DSP provides the best opportunity for Acadia to achieve legitimate and long-lasting nighttime light level reduction. |
