In the conservation world, most of us realize that success in protect­ ing and restoring pollinator populations can be achieved only if farmers are part of the solution—although it is still not clear how we can best work with the largest farms to accomplish this. Two things, however, are certain. The first is that large farms have a negative impact on the environment and are a major driver of pollinator decline. The second is that they do not have to be. Two of the crops with the largest acreages in the United States are corn and soy, and the way that these crops are currently managed is enormously de­ structive of pollinator habitat.

We now have ten times the number of breeding records that we started with, from areas all over Nevada. We also re­ visited historical records of milkweed and found it persisting along roadsides and in ditches, often with signs of mon­ arch activity. At other times during our surveys, however, we were thwarted. After climbing a steep, rocky road up a canyon that looked promising—water, blooming nectar plants, shade, every­ thing that would attract monarchs—we found the vegetation heavily grazed, the stream banks trampled, and neither milkweed nor monarchs in sight.

Such long-term datasets as the one produced by the Western Monarch Thanksgiving Count allow researchers and conservationists to better under­ stand what strategies to pursue in pre­ serving the species. For example, data from this count was used by the Xerces Society to identify the sites with the highest need for active management and protection, as listed in our report State of the Monarch Butterfly Overwinter- ing Sites in California. If it weren’t for the hundreds of biologists, researchers, and volunteers who have contributed to the count and kept it going over the years, we might have little understanding of the degree to which this once-common butterfly has declined in the West.

Petitions to List Key Species as Endangered Finally Bear Fruit A series of decisions announced by the U.S. Fish and Wildlife Service during a two-week period in September and Oc­ tober constitute major steps forward for the protection of insects in the United States. Seven species of Hawaiian yel­ low-faced bees (genus Hylaeus) were given protection under the Endangered Species Act, and two other species, the rusty patched bumble bee (Bombus af- finis) and the western glacier stonefly (Zapada glacier), were proposed for pro­ tection.
