This chapter shall be known and cited as the "Town of Shelter Island Nature Preserve System."
A. 
The purpose of this chapter is to establish a Town Nature Preserve System so that certain Town-owned and privately owned properties can be protected from inappropriate use and development.
B. 
Due to the growth of the population and the development of the economy in the Town, many properties located in the Town are subject to human activity and development. It is necessary and desirable that the natural diversity which currently exists in and on the lands and waters located in the Town to be preserved as natural areas for the benefit of present and future generations in order to achieve any of the following objectives:
(1) 
Heritage: to protect natural areas which provide living museums of the original heritage of the Town and contribute to the public health and welfare of the inhabitants. Rural ambiance and environmental quality have traditionally contributed to the Town's economic base and continue to provide economic opportunity to the residents of the Town.
(2) 
Environmental quality: to protect the existing natural areas and, where desirable, to promote an improved environmental quality of natural areas in the Town, including but not limited to critical environmental areas, significant coastal fish and wildlife habitats and unique site types.
(3) 
Habitat for aquatic and upland ecological communities: to preserve ecosystems and the rich diversity of flora and fauna living thereon, including rare, threatened, endangered and protected species.
(4) 
Unique geological features: to protect the diversity of unique geological features found within the Town, including beaches, dunes, bluffs, swales, kettleholes, kames, morainal highlands and outwash plains.
(5) 
Wetlands: to protect wetlands as a means of flood control, water purification and breeding and nursery grounds for shellfish, finish and other aquatic flora and fauna.
(6) 
Recreational, educational and scientific opportunities: to provide opportunities for wilderness experience, diverse recreational activities and environmental educational programs and academic research programs.
(7) 
Buffer areas: to provide buffer areas to existing natural areas.
(8) 
Watershed areas: to protect watershed areas critical to recharging precipitation into the Town's sole-source aquifer or maintaining surface water quality.
(9) 
Aquifer protection: to protect tracts of land that are critical to the Island's fragile sole-source aquifer.
C. 
It is the intent of this chapter to create a nature preserve overlay system for the Town to supplement but not replace existing Town regulations and procedures.
D. 
It is, therefore, the public policy of the Town to secure for the people of present and future generations the benefits of an enduring resource of natural areas by establishing a Town Nature Preserve System and to provide for the protection from inappropriate use and development of the Town-owned and privately owned properties placed within the Nature Preserve System.
