In landscapes dominated by impermeable surfaces such as pavements and rooftops,…

Tiny but destructive, the emerald ash borer (EAB) is an invasive beetle that has killed millions of ash trees across North America.

Proper calibration ensures that the correct amount of pesticide is applied to an area while achieving the desired level of pest control. To support land managers and pesticide applicators, the UC Statewide…

Rain gardens are transformed land depressions designed for storing and infiltrating stormwater runoff flowing from nearby impervious surfaces throughout urban environments. Coming in a variety of shapes and sizes, rain gardens offer a community friendly approach to generating several environmental benefits,…
