From time to time on my blog you will see posts about the collaborative effort set forth for conservation in our state by the Iowa Nutrient Reduction Strategy. I bet you have also read about the hope I and many have that in working to fund and advance the strategy, we’re working to not only address the concerns of today, but we’re building a better framework for the concerns that will arise tomorrow. A framework that can take another step beyond an out-dated, inefficient, ubiquitous regulatory approach towards conservation concerns. A framework that can be modernized to include a more collaborative effort, more flexible and more targeted, customized from a menu of options to more closely align with that which is in all of our best interests.
One can already look at conservations issues beyond water quality where that sentiment is taking hold.
If you are like me, you’ve probably noticed quite a few large, monarch butterflies roaming about in the heat of the last few days. I seem to notice more this fall than I have in years past. If so that’s great news, and keeping that trend going is the work of the Iowa Monarch Conservation Consortium. It is made up of 40 members working to help with the recovery of the eastern monarch butterfly population. It officially began back in 2015, though the desire to bring it about goes back farther. Members include conservation groups, state agencies, farm groups, universities and agricultural business partners. Earlier this year, the consortium put forth a 135 page document outlining their strategy to keep the eastern monarch off the national endangered species list.
The eastern monarch butterfly overwinters in Mexico on a specific tree known as the oyamel fir. The fact that they return each year to the same trees is remarkable not only due to their completion of a 2500 mile journey, but also in that the monarch that returns is the fourth generation of the one that left. Along their way north then south again, the monarch caterpillar will only feed on milkweed. As crop production techniques have advanced, milkweed, traditionally seen as its name implies, has suffered.
Part of the consortium’s work here in Iowa is to come to a greater understanding of the butterfly and all the factors that come into play affecting its population numbers. Part of the consortium’s work is also to reintroduce milkweed into the landscape. At one time, the previous federal administration felt 7 million acres were needed for such a purpose.
Iowa plays a pivotal role in these efforts. An estimated 40% of the monarch’s that overwinter in Mexico come through Iowa and its surrounding midwest states. Focus has been placed on using “pollinator habitat” in existing Conservation Reserve Program tracts, buffer strips along streams or livestock buildings, borders along field edges, roadways and other local initiatives in Iowa communities.
According to Stephen Bradbury, an Iowa State University ecology and entomology professor who works with the consortium, these small patches here and there will actually do more good than large scale plantings. It’s in keeping with the monarchs natural tendency to congregate on field edges, and it may have an added benefit in helping fight herbicide resistant weeds. According to a Des Moines Register article, Iowa leads the way with 623,000 acres in pollinator habitat, and the Register reports that last year another 1.9 million acres were in the process of being created, with farmers kicking in $55.3 million to do that.
You can find out where the butterflies are along the route using the consortium’s website located here. Populations are kept track of in a couple of different ways. Surveys are conducted along the migratory route as an estimate, and when they return, the area the monarch cover is measured. In 2013 the monarch covered a record low 1.66 acres. In 2014 it was 2.8. In 2016 they covered 10 acres. This year winter storms dropped the number to 7.2. While unfortunate, it along with the illegal logging of monarch habitat in Mexico show there are other factors affecting monarch numbers beyond milkweed. While there is a long way to go on the road to recovery, people across the monarchs route are coming together in the effort. Visiting the consortium’s website, you can find out how you can become involved to.
