The Umpqua Sweets Harvest Plan was announced by the Bureau of Land Management (BLM) in September 2019 and proposes approximately 2,000 acres of logging in the Rock Creek / North Umpqua River vicinity. All but one of the 90 units identified are located within federally designated critical habitat for the endangered Northern Spotted Owl. One unit, 26-2-2A, already fell prey to Lone Rock Timber’s chainsaws back in May 2018 when they claimed they needed to build a road through BLM land in order to access a portion of their own land. Now, the BLM is looking to finish off this stand of 400 year old trees.

The BLM anticipates that their Environmental Assessment (EA) document will be published in August 2020 so there is ample time to get out and visit the units before their fate is sealed. To that end, I have created a series of maps of tree height for all units of the harvest plan. The map information is derived from Light Detection and Ranging (LiDAR) data which utilizes a laser pulse to determine ground and surface heights. There are a total of 18 maps. Use the Map Index to fine the map that covers your unit of interest.

Each map was created as a GeoPDF so it can be used with the Avenza Maps or Paper Maps (my personal favorite) iOS apps while in the field. I have also included a link to a Google Earth KML file of the unit boundaries, which can also be used in the field with the GAIA GPS app.
