A Study of the Black Petaltail in the Umpqua Basin: Field Methods
Using the following map and spreadsheet below I am compiling data on historic, potential, and (to be) confirmed (summer 2019) presence of the Black Petaltail at sites in the Umpqua Basin, Douglas County, Oregon. I am seeking new sites that I have not yet identified, and more detail on sites that I have already identified in a broader sense (e.g. meadow complexes). You can click on any individual site to see the data associated with it, and/or zoom in to see what the area looks like. As I obtain more information, I will update the database and map.
Click the leftmost symbol in the map header to see a legend. Or, click the full-screen symbol on the right side of the header to see the map full screen with the legend. Zoom in and click on any marker to see data associated with it.
