Do you have a  Leaflet map ? Yes. Can you panned and and zoomed to a particular event or ROI in the map? Yes. Then, how can you share that map zoomed or centered with ROI/events to your webpage or email as a link? One of the answers may be set the zoom level and set view near the ROI.  Alright, what will you do if you have a map with multiple ROI/events? Do you make multiple maps with multiple zoom level and view? You can, but probably not a good idea to do that.  The solution comes here, leaflet-hash.js , solves your needs, it is a JavaScript library written by Michael Lawrence Evans , which appends the URL hashes to web pages automatically and the hash changes with Leaflet map on drag or zoom. The hash consists of map zoom level and latitude/longitude of the center of map viewport, everything you need to share the map with focused ROI as link in following simple steps:

" Freshwater Ecoregions of the World, (FEOW)  provides a new global bio-geographic regionalization of the Earth's freshwater biodiversity.  Covering virtually all freshwater habitats on Earth, this first-ever ecoregion map, together with associated species data, is a useful tool for underpinning global and regional conservation planning efforts, particularly to identify outstanding and imperiled freshwater systems; for serving as a logical framework for large-scale conservation strategies; and for providing a global-scale knowledge base for increasing freshwater biogeographic literacy. " "Over a decade of work and contributions by more than 200 leading conservation scientists have produced a first-ever comprehensive map and database of the diversity of life in the world’s freshwater ecosystems. The map and associated fish data – a collaborative project between World Wildlife Fund and The Nature Conservancy."   For the fish lovers, the map i...
