Encroaching conifers obscure a stand of oak in Redwood National Park.

Oak woodlands are "some of the most biodiverse ecosystems in the North West," said UC Cooperative Extension forest advisor Yana Valochovic. "They are preferentially used by a lot of different bird species."

In the past, fires would burn out conifers and underbrush on oak woodland annually, but aggressive fire suppression is enabling them to spread unchecked, crowding out oaks.

Yanachovic is finishing a three-year research project on conifer encroachment, and AB 1958, if passed, would put policies in place so people can get rid of the conifers without jumping through as many bureaucratic hoops as before, the article said.

“It clarifies that the cutting of younger conifers out of oak woodlands does not qualify as conversion of timberlands,” she said.
