Available Risk Layers
4 types of risk layers to explore:
Anthropogenic Night Light Source
Sky Light Pollution Ratio (Skyglow)
Transient Noise Exceedance
Chronic Noise Exceedance
For more information, visit the "more info" page.
Selecting Parameters
Step 1: Select category
Step 2: Select from the dropdown or search by mammal species or by national park unit
Different Types of Results
Metrics such as percent above/below threshold values for individual risk type
are available for mammal species range and park unit boundary. Associated maps are also
available.
Different Types of Results
Available only when 'Anthropogenic Night Light Source' layer is the selected risk type.
A chart showing the changes in radiance values for the selected mammal species or park unit will appear.
Available only when selected category is "National Park Units."
A list of species which distribution ranges overlap with the selected park unit will appear. Species list is currently available for National Parks.
Export Map
Available in the Side Bar Export Tab
Allow exporting of maps in various file formats.
