Foraging Native Plants: Look to Your Own Backyard




Native plants play an important role in living sustainably.  They furnish habitat, create shade, improve the soil and provide edible and craft materials.   To put it simply, California natives are remarkable additions to the garden ecosystem. But it’s important to remember that these plants are also critical components of natural ecosystems.

The increased interest in edible and medicinal native plants creates several unintended consequences.   Most important is the overuse of natural stands of native plants growing in the wild.   This is not just a problem in California; over-collecting of native plants is a critical issue world-wide, leading to the extinction of entire plant species.

While some California native plants are still common, others are rare – even endangered - in the wild.  Humans have played a key role, primarily by destroying habitat (building houses, roads, etc.).  Global climate change is putting further pressures on wild plants and animal populations. 

To stress wild populations further by wild foraging is unsound.  In fact, there are legal, health/safety, practical and ethical/stewardship reasons to limit wildland foraging.  For more see: http://mother-natures-backyard.blogspot.com/2016/06/sustainable-living-foraging-for-native.html

Trees and Shrubs for a Changing Climate: Plant Them Now!

Native shrubs at CSUDH look good despite years of drought

The last four and a half years have been difficult for those living in Southern California.  Lack of rain, dry winds and high temperatures have stressed everything.  Unfortunately, these are probably just a taste of things to come.  Now is the time to choose plants that will be able to thrive despite the changing climate.   Here are a few resources to help:
