The Haven is all about teaching, research, and outreach to save the bees. Our programs are consistently rated highly by our visitors; we've grown every year of our existence and would love for that to continue. For details about our past accomplishments, please see our annual reports: 2018, 2017, 2016, 2015, and 2014.
A grant that provided half of our support recently ended, and I am seeking your support to help keep these successful programs going.
What you can do:
1. Donate here. The Haven is supported solely by grants, donations, and volunteers. A generous Häagen-Dazs gift established the garden, but Häagen-Dazs does not provide ongoing support. Recent funding has come from the California Department of Food and Agriculture, the UC Davis College of Agriculture and Environmental Sciences, the USDA, and the California Center for Urban Horticulture.
Individuals and local clubs such as the Roseville Better Gardens Club and the Sacramento Area Beekeepers Association have also made much-appreciated donations.
If the 3500 people who've attended a tour, Haven event, or class so far this year each gave $10, we'd be covered for seven months. While large donations are great, many small donations are just as important.
2. Attend our fall fundraiser on September 21. Details will be posted soon on the Haven's web page.
Thank you. Together we can keep this unique garden going strong.

I've had several questions recently about the Bambeco solitary bee house sold at Costco (they sell the Swiss Alps model), so I decided to head to my local store to check it out. While the price is amazing, the house has a few features that are not so ideal. For details on what makes a good solitary bee house, see here and here.
The depth. At 4.5 inches deep, it is sufficiently deep to allow the production of female and male bees.
What's not so good:
The nesting tube diameter. While the variety of diameters is good, solitary bees need tubes from 3/16 to 5/16 in diameter. While other arthropods, such as spiders, may use the larger tubes, they will not be used by bees.
Limited protected overhang. The nesting tubes should be placed so that the entrance has a bit of protection. That's why we make our houses at least an inch longer than the tubes.
The nesting tubes are glued in place. Once a tube is used it should be replaced to help prevent the build up of pathogens.
March 13, 2019: winter update
The bee house is not holding up well to the winter weather. Here's a photo showing some superficial mold as well as separation of the sides from the base. Note that I added extra protection by attached redwood fence boards to increase the cover of the roof.
