Re: Call for input on Collawash River map

Assuming the road density in the upstream watershed of the Clackamas is similar to the road density in the Collawash watershed, then mkrochta's photo shows that forest roads don't necessarily destabilize the terrain to a critical extent. It could be that the road contractor for the Collawash goofed...

Re: Call for input on Collawash River map

I'm going to try to get to some of Koda's questions soon, but now and for the next couple days I have to sign-off and get back to the forest. mkrochta,Thank you again for the replies. I realize any reply is voluntary on your part so any dialog is appreciated. Mcds sparked another question, I cant i...

Re: Call for input on Collawash River map

The 6 page Spotted Owl PDF does not contain the word 'road' One more simple question, can you look up the day/month/year of the photo you posted? If not, the if you post a link to the original image file, the exif data probably has the date and I could look it up there. http://www.portlandhikers.or...

Re: Call for input on Collawash River map

But given 'global climate change' I would think several small pools (or reduced stirring in a large pool) would be better than one large well stirred pool because a small pool can adopt a genetic adaptation more quickly compared to a large pool. Populations that don't adapt will die out, opening up...

Re: Call for input on Collawash River map

Another thing: there was a request earlier on for a map that included the roads the USFS proposed to decommission in the Collawash in 2011. Although I don't have the tools on me today to incorporate these into the Bark map, I thought for now it would be helpful to post a link to some other maps show...

Re: Call for input on Collawash River map

crickets and silence. I didn’t think my questions would be responded to from Bark…. Hello Koda - sorry for the delay, I've been in the forest the last couple days. Glad you followed up. To answer your question about wildlife and roads, the science around this is overly-plentiful. Not just for deer ...

Re: Call for input on Collawash River map

While regeneration is a goal of road decommissioning, the most significant reasoning behind doing this kind of thing is reducing impacts to water quality and fish. Many spur roads in the forest were built very hastily long ago to access timber, and weren't meant to be left open as long as they have...

Re: Call for input on Collawash River map

Isn't the idea of removing a road that the underground biota can be reestablished and a more natural form of forest regeneration occur? I've assumed so, but haven't read or heard what the logic used by planners actually is. It's relevant to this discussion. Anyone know? While regeneration is a goal...

Re: Call for input on Collawash River map

I can't see enough detail on the map, but Thunder Mountain trailhead is either just off the map or at the edge of it, and I can't tell if the road is marked for decommission or not. In addition, the road to the Baty Butte Trail is similar. Personally, my take on BARK is that they want to close ALL ...

Re: Call for input on Collawash River map

Thanks for all your input. It helps to have pointed out that I missed some areas, and that this needs better labeling. I'll get on that. This map is a first draft and this response is really valuable. As a reply to the comment that the USFS has identified many of these roads already for removal, nex...
