Map of Life

This demo release "allows you to map and produce list of species anywhere for ~ 25,000 species (including all described birds, mammals and amphibians...)"

Future releases "plan to greatly increase and enhance data coverage and functionality. We will soon add more datasets for vertebrates and extend coverage to plants and invertebrates. You will be able to:

1. Filter data based on characteristics such as seasonality, or date of observation
2. Flag and edit distribution data and provide feedback about those edits"
