CalFire, as the lead agency which approves timber harvest plans, does not require specific disclosure in the plans of which chemical herbicides will be used, how often, or when. Only with lengthy, time consuming research can public members find this information, after the chemicals have been applied.
The chemicals in herbicides find their way into soils, where they may be toxic to insects, worms, fungi, and bacteria. These small organisms make up 95% of all known species, and are essential to both the structure and function of ecosystems.
Glyphosate (more popularly known as "Roundup") is one of the most commonly used herbicides. Contrary to expensive ad campaigns, it is not a harmless herbicide.
"Glyphosate and its degradation product amino-methyl-phosphonic acid have been found in air, rain, groundwater, surface water, seawater and soil. These studies show that glyphosate persists in soil and water for prolonged periods of time. In addition, the amount of glyphosate detected in samples is increasing over time. The chemical is accumulating in our environment. It also accumulates in animal tissue." Full article
As more forests are leveled by clearcutting in California, the use of herbicides continues on every year. In California 258,000 pounds of chemical herbicides were used for forestry by 2006. Herbicides are sprayed on clear cut areas to keep the native plant species from regenerating and competing with the replanted single-species plantations. This destroys diversity and the food sources for many species of wildlife.

Studies show that the plantations that replace diverse forests are extremely fire-prone.
When there are wildfires in plantations, the percentage of trees killed is much higher than in older, mixed-species forests.
The slash that is left creates a greater wildfire danger.
