This section of Places>Biogeographic provinces is somewhat unconventional in that it does not adhere precisely to province boundaries as defined in 2007 by Audubon/TNC. Rather, it reflects an exciting new collaboration between Discovery Southeast and residents of what we define as the Greater Chilkat Watershed.
At the northern tip of Southeast Alaska’s inland waterway, 5 silt-laden transboundary rivers—fanned like fingers of a giant hand—converge into a fertile, glacier-fed ‘palm:’ Jilkáat, cache (Chilkat River valley). Near the estuary, the port of Deishú, trail’s end (Haines) greets raincountry travelers bound for drier, boreal realms in Canada and interior Alaska. Here is one of the continent’s great ecotones—a zone of transition, connectivity, genetic mixing, and commerce.
Here, also, is home to Lynn Canal Conservation (LCC), stewards for the past half century of land we call the Greater Chilkat Watershed (GCW). In early winter, 2019, LCC invited me to compile a biogeographic and cultural atlas for this region. The map below shows its boundaries. Unlike the other mainland Biogeographic Provinces, which are clipped to the AK-BC border, this one extends inland to the heads of Canadian tributaries feeding ultimately into Chilkat River.
Because “atlas,” in its printed form, might conjure something static or ‘finished,’ we call this evolving effort a living atlas. Our intent is that this collection of maps and stories continues to grow, beyond conclusion of any one contract or funding cycle. In its online form—here on JuneauNature—the atlas is interactive. It coordinates and solicits contributions from the Chilkat Valley community—serving to identify gaps and unknowns as well as sharing what we do know.
As our project evolves, various branches of the mapping and story-telling effort will be listed below as linked content-pages, also accessible from Lynn Canal Conservation’s website.
Your feedback is appreciated as we develop this ‘living atlas.’ Among the early, draft products will be geopdfs for navigation within the Greater Chilkat Watershed. These are especially useful in the often-off-line GCW, because they give your position, track, photopoints, etc. using only the GPS on your device. From my constantly updating ArcGIS project, it’s easy for me to crank out a custom, high-res geopdf for any subregion or subject matter. Just let me know what you need!

Journal for July, 2019 visit:
From 20190706 to 08, when my sister Tina was visiting from Mexico, we ferried to Haines for a first meeting and exploration with folks from Lynn Canal Conservation. My 61-page journal is here.
