Western Monarch Butterfly Resources
13 Top Western Monarch Resources for Monarchs & Milkweed

The western monarch butterfly population is in deep decline, and the western monarch migration is collapsing due to several factors including habitat loss, pesticides, and climate change. A frequently forgotten factor is the unintended consequence of biological pest control.
Monarch enthusiasts in warm western regions are dealing with a unique set of circumstances and issues when it comes to butterfly gardening and raising healthy monarchs. These include elevated disease and parasite issues that are common in places with longer growing seasons.
This graph below illustrates the dangerous decline of western monarchs:

What makes this decline even more astonishing, is how many more overwintering sites are being monitored now compared to three decades ago.
While experts and enthusiasts both struggle to find viable solutions to bring back the western monarch population, these are some of the organizations, businesses, and communities already in the trenches…

Please comment below if you know of other good western monarch resources

According to the admin and many members of this group they’re saying that the climate change has many Monarchs laying eggs year around all over California during the winter.

As far as increasing the overwintering numbers in the West Coast, Xerces Society should encourage everyone to home-raise a few plus to remove the hands off in California State.
It is pointless concentrating only on creating more habitats when there aren’t enough butterflies around to use them. 🙁
I clicked on “the beautiful monarch” link. It said not available. I did notice it said archived 2023 below your link for it. Does this mean it is inactive?
Also you have a lot of information here but nothing about legislation done for monarchs in the state of West Virginia. Which was established for monarch protection in 2004. “West Virginia Monarch Butterfly Day Sept 12th” FYI. Founder and NSDAR National Conservation gold medalist Heather Tokas
Lastly how did you select only Monarch Watch and Rose Franklin on the east for egg and caterpillar suppliers when there are about 60 of us?
Hi Heather, the beautiful monarch link still works on my end, but the group has been archived…also, this particular page is for western monarch info, not the east coast. I am not familiar with your website but you can email the info for consideration: contact page
