The Arctic National Wildlife Refuge is a diverse but fragile ecosystem.
The 1002 region in particular, a coastal strip caught between the Brooks
Range Mountains and the Beaufort Sea, is an intricate network of species
and their surroundings that stand to be severely damaged by human activities.
It is essential to establish a baseline of the ANWR ecosystem in order to
create an assessment of the effects of oil drilling on its well-being and
to take the proper precautions to preserve it.
In order to create a comprehensive model of the ecosystem, we have to
set up the important parameters and components that define an ecosystem.
Based on ecological models from multiple references, we have determined
the main constituents of an ecosystem to include the following: geography
structure and relief, climate, soils, hydrology, producers and consumers,
decomposition and soil processes, energy and nutrient cycling, and interaction
between terrestrial and aquatic communities (if relevant to the area of
study). By developing a descriptive and quantitative model for each constituent
we can compile the information for the structure and function of the ANWR
