Depending on the type of crop or type of growing that is being done different pests and predators will be present. While I had significant trouble finding specific pests and IPM management techniques for the Santa Cruz area I did find the gospel on the subject. Rather than just merely state the pests for the area this breaks down the most likely pests based on crop that is growing and tells you the most effective, sustainable technique to have your crops prosper.

UC IPM: Statewide Integrated Pest Management Program  is the holy grail of IPM knowledge and techniques. If you look at the site you'll initially notice the format in that the pests are broken down based on the type of work that is being down; whether that is Home/ garden, agricultural, natural, or exotic the pests are broken up. Further if you click on one of the links then it is broken down either by plant or by pest. For example if you click on the Home/Garden one it breaks it down by either pests of home, pests of garden, some common pests, and pesticides. Each one of these options has at least 3 subsets and continues to break it down even further. It is an extremely valuable text and the subject and definitely think that this link should be included in this section of the bio-regional directory even though this text is not particularly regional. Due to finding this glorious text on Integrated Pest Management I feel that continuing to research and specifying pests and techniques for just the Santa Cruz area is pointless as this UC Davis research seems to be all encompassing. Regardless of the relation between the pests and plants that are being researched for this area or outside of this area this text seems to have the information. Though I would also like to say that this all encompassing, beautiful website does only apply to California, last I checked Santa Cruz/Monterrey County are still a part of California so I guess in that regard it actually is regional but significantly larger than the specified area for this directory.
