Wednesday's Letters to the Editor

Science and logic

EDITOR: George A. Hollister (“Vacation from logic,” Sept. 15) presented significant insight regarding “logic” and coho salmon decline. Cumulative impacts, primarily human-caused since the 1850s, have pushed coho salmon to extirpation in the Russian River and beyond. Regrettably, 30 years ago, agencies removed naturally recruited logs (wood) from streams with unintended consequences. The addition of wood is vital to the ecological health of streams; this is based on scientific research, common sense and logic. The following are created by log structures in streams:

Refuge during high winter flows.

Pools for juvenile fish during the heat and low flows of summer.

Feeding opportunities by trapping organic matter for the aquatic food web.

Channel shaping and stabilization.

Enhanced stream function.

Hydraulic complexity.

Collection and sorting of gravel and cobble for spawning.

The California Department of Fish and Wildlife, NOAA Fisheries and local organizations have escalated the installation of wood for fish habitat, a high priority for salmon and steelhead recovery.

As the Department of Fish and Wildlife fisheries supervisor for restoration of coastal streams throughout the Bay Area, I invite interested citizens to contact me via the department office in Yountville to continue this conversation based on science and logic. Our valuable fishery relies on it.

Permanent pawns

EDITOR: Let’s try a little nonpartisan common sense here. Government shutdowns have happened more than a dozen times in the past, under both Democratic and Republican administrations. They will happen again and again.

Once active, does anyone really think that a government-run health care system will not be a negotiating pawn in the future?

Federally funded affordable health care will be the crux of all future budget agreements. We will not be whining about closed parks. We will be fighting for our lives, literally.
