Salmon lose diversity in managed rivers, reducing resilience to environmental change

December 5, 2019
From the National Oceanic and Atmospheric Administration (NOAA)

The manipulation of rivers in California is jeopardizing the resilience of native Chinook salmon. It compresses their migration timing to the point that they crowd their habitats. They may miss the best window for entering the ocean and growing into adults, new research shows.

The good news is that even small steps to improve their access to habitat and restore natural flows could boost their survival.

Sacramento County: Free Your Recycling

November 2019

Many plastic food and beverage containers can be placed in your curbside recycling cart. The County’s curbside recycling program accepts plastics #1 – #7, with the exception of Styrofoam…As long as the plastic item has a #1 – #7 stamped on it, usually on the bottom or side, and located within the “chasing arrows” symbol, it is ok to put in your recycling cart.

Plastic bags are a little different. Thin, stretchy plastic, like zip-lock bags, single-use grocery bags, bubble wrap and air pillows used for packaging, are not accepted in your curbside recycling cart. However, some local businesses do accept these items for recycling. Visit the Plastic Film Recycling website to find a nearby drop-off location. And, please remember: if you bag your recyclables, do not put the bag in the recycling cart. Empty the recyclables into your cart, reuse the bag, or toss it in the garbage cart.*
