Wildfire preparedness for home landscapes

The wildfires in Hawaii make it clear few locales are immune from the devastating effects caused by wildfire. Despite Western Washington’s wet reputation, we also are not immune to wildfires, especially during drier years. Here in Skagit County, we also are facing severe drought.

A recent climate impact study developed by the University of Washington’s Climate Impacts Group reported that the temperature in Washington has increased 1.5 degrees F in the last 20 years.

Firewise landscaping is an array of practices promoted by the National Fire Protection Association and others to create a defensible space around your home that can slow a wildfire or discourage ignition. Here are a few practices you can take to be prepared this fire season.

First, remove fire fuel wherever possible. Clean your gutters of debris and make sure your roof is clear of leaves and moss. Install one-eighth inch metal mesh screening to block embers.

Never store flammable materials underneath elevated decks or porches (for example firewood) and clean dead vegetation from between deck boards and under the deck. Visit Firewise.org for more information.

Second, plant for moisture resilience. An excellent publication has been produced by Washington State University, Oregon State University and the University of Idaho titled Fire Resistant Plants for the Home Landscapes. The free pdf download includes an extensive list of plants that tend to be less flammable. https://catalogue.extension.oregonstate.edu>pnw590

Drip irrigation systems that deliver just the right amount of water at the correct intervals help conserve water during dry months. See our recent blog post on DIY Drip Irrigation: skagitmg.org/diy-drip-irrigation/.

Third, create a defensible space. Fire professionals often talk about maintaining a defensible space within 100 to 200 feet of your home. Within this area modify the landscaping to give your house the best chance to survive on its own. Beyond using inflammable hardscape, groundcovers such as succulents and even a narrow band of turf grass can provide valuable protection. Keep grass near your home (both turf and natural meadows) watered, if possible and mowed during fire season to no more than four inches.

What About Mulch? Mulch helps to retain soil moisture over the summer and insulate in winter and can be used beyond five feet from the foundation. Do not use flammable mulches or groundcovers within five feet of your foundation. WSU scientist Dr. Linda Chalker-Scott recommends using fresh arborist chips because valuable nutrients are lost during composting.
