Welcome to Explore Teach Conserve, or the ETC podcast by the University of Minnesota Extension, where we talk with people about exploring, making discoveries, and solving problems to better manage our natural resources, and we share ideas to help you learn more and get involved. This is an older episode from when we used a different title, The Naturalist, but the conversation and ideas are still fresh. If you enjoy it, we hope you'll subscribe and listen to more episodes of Explore, Teach, Conserve, or the ETC. Hi, I'm Santiago from U of M Extension, and this is The Naturalist. It podcasts that aims to explore the various topics within the world of Minnesota natural resources, all while trying to capture great stories and talk to people about the environment. This week, we were talking about bees and the efforts being made in Minnesota to gain a better understanding of their populations. He first talked to Elaine Evans, an extension educator with the University of Minnesota, about native bees and the bee diversity studies currently being conducted. Later, we get a chance to talk to Britt Fosberg Program Coordinator for the University of Minnesota Bee Atlas program about the B atlas program as a whole, the impact of citizen scientists on the program, and the goals and challenges of this initiative. This is the sound of a carpenter bee. I personally don't know much. about bees outside of their impacts on pollination and that they are very sensitive to environmental changes. For this episode, I set out to learn more about bees in Minnesota and how they are doing. Are they doing badly? What are researchers studying exactly? And how can citizen scientists get involved in the process? So I am Elaine Evans. I'm an extension educator with the University of Minnesota, and I focus on bees, mostly native bees, and work on pollinator habitat and bee conservation. What are some of the major projects you're working on right now? One of them is with the Minnesota Bee Atlas, I'm working on a bumblebee survey with them. So we have citizen scientists, volunteers that have adopted routes all throughout the state of Minnesota, and people are going out and making observations of bumblebees along these routes. They've been trained in bumblebee identification, and then they're also taking photo vouchers of some species that are a little more difficult and reporting these data back. And by doing that, we're getting some nice population level information about not just where these bumblebees are, but how they're doing. So this is a nice compliment to another nationwide project called Bumblebee Watch, where anyone anywhere can take a photo of a bee and submit it. And that gives us a good idea of which bees are where, but not necessarily, it's kind of more, you know, harder to get population level information. I'm also I also do bumblebee surveys locally just in the I'm based in St. Paul and we do our 11th year doing bumblebee surveys in parks in the Twin Cities and so this one we're we're revisiting particular sites to try to get this kind of this long-term data to look at population trends for bumblebees. So I'm also involved in research projects. So I have a research project looking at some comparative, asking a comparison between kind of how bees used to be doing and how they're doing now for, native bees. Okay. So we have, um, we did collections of bees in a couple areas where we have good historic collections in the insect collection here at the University of Minnesota. So then we've been going through and databasing all those bees, which is a huge project, which the, actually the DNR has been involved in that too. They're doing some similar, um, trying to find find out what bees are where kind of project. And then we did focus samplings and areas where we had lots of those records so we can do some of those comparisons to really kind of tell how bees are doing compared to how they used to be doing. Right, well that's a lot. Yeah, and then the other main thing that I'm working on is work with the Rusty Patch Bumblebee. So that's the first B to be listed as an endangered species federally. And it does, one of the few places where it still occurs is in Minnesota, particularly we have a lot of, you know, relatively a lot of records in the metro, Twin Cities Metro here. So, so there are a lot of, there's a lot of work just on, you know, working with the Fish and Wildlife. life service and doing some education and outreach about the Rusty Patch Bumblebee to get homeowners here aware of how they can help Rusty Patch Bumblebee and also some research projects on trying to figure out what's going on with them and how we can help them. So how do those records show bee populations? How are they doing compared to when the last time those records were actually you know, gathered and studied back in the day. Yeah, yeah. So we're, so for that historic comparison project, we're still getting the data all together. So I don't have the answer for, you know, how things are here. We know that there are some big differences in terms of some species, But it's a difficult question to answer overall was just how bees are doing because they're so diverse and there's so many of them that we don't know a lot about. So, I mean, just as an example, it's just in the last couple of years since we databased the records in the insect collection here that we've been even able to talk about how many bee species do we have in Minnesota. Right. So before a couple years ago, we didn't even know how many we had. So knowing how they're doing is a big step forward from that. So we do know, you know, honeybees. We know how they're doing because they're a managed bee and they're in these boxes and you can open them up and see how they're doing, you know, compare their health. And so we do know that honeybees are having some big health problems. So it's about 40% of honeybee colonies that die every year. Okay. But the good news side of that is that beekeepers are really good at keeping honeybees and they know how to, you know, they can make more colonies. honeybees aren't going to go extinct. We can breed more. We can replace those colonies. But honeybees are kind of like livestock. So since they're a managed bee, you can imagine if, you know, people raising dairy cows were losing 40% of their cows every year, they'd be in a state of panic. And I mean, bees are a lot different than cows, but still, it is a big stress on the beekeepers to have these health problems. So that brings up an interesting question. Given that, I guess, honeybees aren't doing so hot, you know, what would happen if, big what if, what would happen if, you know, native beeves were kind of suffering from the same situation and her numbers were dwindling on that scale. Yeah. And all we did have was honey bees. What type of environmental impacts would we see from that? Right. So we do one group of bumble bees that we do know about our bumblebees. We have just more information about them. So we know it's roughly one out of every four species of bumblebees that are in decline. And that's globally, you know, lots of evidence for bumblebees having problems. So, you know, honeybees, we rely on them a lot for pollination in big agricultural fields where there are these huge fields, you know, in particular crops where we can bring honeybees in. But around all those fields, there are native bees too. So native bees are kind of all over the place. And they actually are contributing a lot to pollination of crops. And additionally, there are a lot of native plants that are relying on the native bees for pollination. So honeybees are great for pollinating certain things, but because of their behaviors and their choices, they don't visit everything. So it's roughly 90% of plants overall that are depending on animals for moving their pollen around. And a lot of that is happening from wild bees. So the ecological impact of those plants, you know, so many plants, losing their ability to reproduce as effectively would be really dramatic for, plants are at the base of the whole food chain, you know. So just going up the food chain from plants to all the insects that eat plants, all the birds that eat insects, all the, you know, other mammals and, you know, following it up that way, looking at the water cycle, if plants are doing well and they're not, you know, filtering and it's a really gigantic impact. Yeah, it's quite a situation. And I feel like it's easy to forget how how much one little thing can, you know, kind of trickle up or trickle down depending on the way you look at it. Yeah. And just because of the, you know, pollination that they're doing, it's this, it's this big connection that's, you know, affecting a lot of different communities. So I guess going forward, if the situation was where, you know, you found out this information and these weren't doing so hot, what would be some of the steps that as a state, you know, we could kind of take to better that situation? Is it really just dependent on, you know, local communities kind of handing together in, you know, investing in pollinator -friendly installments? or is it, you know, really comes down to the legislative, you know, kind of taking initiative on the political side of things? So, so one of the nice things, I'm one of the reasons why I think a lot of people have gotten engaged and interested in the topic of pollinators is because there's a lot of different levels of action that can make a difference. So you can make a difference by having a pollinator garden in your yard. providing flowers, providing some places for native bees to nest, and keeping those flowers free of pesticides. But there's other levels you can work on, too. So with, you know, 80 to 90 percent of land being an agricultural production in the, you know, in the Midwest here. these bees existing everywhere, there's a lot that can be done for trying to improve habitat for them in other places too. So having state programs that encourage and that provide incentives for farmers to create pollinator habitat. And actually in the state here, we have a lot of great programs that are doing that, those can make a huge difference for providing these, you know, kind of restoring native habitat out throughout the state so that these bees can have someplace to live. Those can make a huge difference. And even, you know, up to the federal level, working with the new farm bill that's going to be going through. And again, a lot of the things that can have, help are getting these incentive programs for farmers to compensate them for creating pollinator habitat. Those are really effective, great ways to promote habitat. I think another thing we can do a better job of in the state is somewhat just really kind of communicating with farmers sitting down at the table together and and talking about things, habitat that's already in the farmland that can be, can be either kept there or you can get more of it in there, things that can be done to help bees do well, things like planting cover crops and different things that actually flower and provide food for the bees, having wooded areas that provide nesting habitat for bees. Also, to sit down at the table and talk with farmers about how to protect those habitats then from accidental pesticide drifts. Because we don't, the tricky part with creating all this habitat in farmland is making sure that we're keeping it safe for the pollinators as well. Right. So that sounds like a huge challenge if, but I feel like these are one of the few, well, not few, but these are definitely one of the insects that people are like, oh, almost the time that they're pretty going to hoe about helping out. Yeah. You have the occasional friend that freaks out every time you see a bee, but I don't think that's a thing. Yeah, people in general are starting to understand how important they are. And if we broaden the conversation out to pollinators, then we can bring in really charismatic pollinators like the Monarch that a lot of people, you know, remember a time when they were everywhere and have really noticed the dramatic difference with the drop in their population. Timeline-wise, when are some of these projects, these new surveying projects, when are they, you and your team, when are you aiming to kind of be done with those and have some. of those numbers that are more concrete. The historic comparison project is one that will be finding up. We should have results to talk about that within the next year. Some of the projects with the Rusty Patch Bumblebee are just starting up. So those are going to be ongoing. There's some urgency with that because of the listing of the Rusty Patch Bumblebee. So hopefully we'll be able to process that information quickly and get that information into practical recommendations for recovering the Rusty Patch Bumblebee. What were their populations and kind of ranges before during danger kind of listing? Was it a bee that was kind of spread out across the state, kind of seen everywhere, or is it very specific to a certain part of the state? state or country. As you said, I think Minnesota is the only place that has it now, or was that? One of a handful of places that's right. So it used to be found throughout, from here, Minnesota was kind of as far west as it went, but then it went all the way over to the east coast, up into Canada, down into the southern part of the U.S. as well. So it was really widespread. And it was one of the most common fees. So in Minnesota here, it was, you know, like in the top five for the species. And, you know, so, yeah, we saw it really regularly, really widespread. And it had a really dramatic sudden drop around the year, where all of a sudden it just wasn't being seen. So there were a number of years where people were looking and not finding it. As an example, in the, in the Twin Cities here, I used to see them commonly. I didn't see them from 1999 until 2010. And their populations were just so low. So, you know, I was doing surveys, looking for them, but I wasn't seeing them at all. And so I've been seeing them since 2010, but every year when I see them, I only see, you know, maybe five individuals if I'm lucky. So it's helped to have programs like Bumblebee Watch where anyone anywhere can just take a photo of them and upload. them. So we've gotten a lot more locations where they're found around the Twin Cities, but it's still every year it's maybe, you know, a dozen places where people see them and take pictures and send them in. So they're also still, it's a similar situation actually in Madison, Wisconsin. They have a same kind of thing where they're seeing, they see a few of them there every year or two. Okay, that's really interesting. Just the idea of having a, you know, such a widespread be kind of just declined to the point where not as visible anymore. It's really, well, yeah, it's pretty concerning. We'll be right back after the short break. Hey, Santiago, I heard about an event on September 30th. Yes, Tracy, this 30th, which is in about two weeks, we have National Public Lands Day. Oh, that sounds fun. Can you tell me more about it? Yes, so National Public Lands Day is a national effort where we get people together to do some service on public lands. So this year, we have about 12 sites scattered around the state, ranging from Rochester to we have another site in Boulder Lake, which is in north -eastern Minnesota for people who don't know. And yeah, we have everything ranging from buckling removal all the way to helping install pollinator garden, so there's something for everybody. That sounds like a lot of fun. I like to be outside. Where can I find more information? If you want to register for a site and learn more about the program and what we're doing this year, feel free to log on to www.mastonaturalist.org. The B-Atlas program is a major citizen-scientist-driven survey program for the university. of Minnesota. When it's finished, the program will have a ton of data to help shape a better understanding of bee populations in Minnesota and their distributions. I'm Britt Forsberg, and I'm the program coordinator for the Minnesota B. Alice. Out of the University of Minnesota Extension. All right. How long have you been involved with B. Atlas? We've just finished our second year with the B. Alice. Okay. Okay. Um, so, so. So what is Bea Atlas? Sure. So we are a four-year funded grant program funded by the Environment and Natural Resources Trust Fund. This is usually called LC-C-MAR, but the pot of money is actually the Environment and Natural Resources Trust Fund. So over these four years, including three field seasons, we're using citizen scientists volunteers to help us understand the diversity and distribution of native bees in Minnesota. There are probably about 400 different species of native bees in Minnesota in addition to the European honeybee, which is not native to North America. So our volunteers are looking at a number of different protocols, and then we'll be able to combine our data from our volunteers with that from others at the University of Minnesota, Minnesota DNR, and historic collections to create one publicly accessible online database that will have as much information about bees as possible. All right. That sounds really cool. How's it going so far in terms of getting people on board and working with the other departments and different organizations across the state? I think that our one challenge is going to be the technology behind making each database talk to each other. So you can have one query that accesses multiple points. But in terms of making connections, we have met our targets for volunteers. We have certainly know everybody else in the state who's working on bees. And so I think we'll have quite a bit of data at the end. Yeah, I can imagine that being a ton, a ton of data. So this is a pretty ambitious project I'd say, right? It's just like easy to be, but now done before another state type of thing. Other states do have more information. Wisconsin has cataloged all of their bees. So officially, in the last historic record for Minnesota, or last census of these in 1990. There were 67 different species. Wisconsin has over 400. So clearly difference being just that Wisconsin is taking the time to look for them. And we haven't combined all of our resources. Certainly lots of people research bees in Minnesota and know that there are far more than 67 species. This will be the first, first way that people are combining all that information into one place. And considering how big this it is, how has it been like coordinating those efforts, do you have persistent scientists collecting data in different corners of the state? Or is it kind of centered around a specific location? Our goal is then to spread it out geographically. There tend to be more volunteers in the metro area. That's where more people live. So we've been able to get some of these outstate areas by offering our workshops in different places. There are still places that are hard to get to along the Iowa border. It's not as populated. There's a lot of agriculture. So we don't have as many volunteers there. We don't have as many volunteers as we'd like in the far northwest corner of the state. But all of our, all of the locations where we have volunteers working are on our website. In terms of reaching volunteers, you know, what type of strategies have you been using to find these citizen scientists, volunteers, has been pretty fairly, you know, easy. Do you just have a ton of people flooding in just being, oh, I want to help out with bees and stuff like that, or has it been kind of a challenge trying to get the word out? We definitely lucked out by having our project come as when it did, right? There's a lot of media attention to bees. A lot more people are aware that they're in trouble, and so a lot, there's a lot of public interest. For the B blocks in particular for one of our protocols, we looked at what different groups would either be interested in the data that we're collecting or in the information that we're sharing. So large numbers of those volunteers are from places like nature centers, environmental learning centers. They're keeping their observations near a pollinator garden or a building where they have a lot of interpretive opportunities. We also had county land managers who are quite interested. They want to better document the diversity that they have in their parklands. Another large group have been master naturalists or other volunteers as part of the DNR, S &A Steward program. So these folks are already volunteering at a scientific and natural area in the state, usually looking for, are there down to trees, has there been vandalism, you know, what different things are going on in that area, but then adding a B block to observe at the same. same time. When you have these people coming in and interested and stuff like that, how does the training come along? Is it very simple? Is it, you know, intensive or, you know, are you trying to get the best data possible by giving them all the tools and information they need to get this thing going? Sure. It depends on which protocol area they're interested in. The simplest area we have is just sharing photos of these through the website, I Naturalist. So sometimes these are people who come to a workshop where we practice taking pictures of bees. We have some tips about ways to get better pictures of bees or ways to get better photos that are more likely to be identified by others. But they're often just hobby photographers who are already using i naturalist or who've seen us online and happen to submit their photos. So that's pretty easy. The middle level of protocols monitoring are bee blocks. We have written materials and then online videos. These volunteers are spread the most throughout the state, and so it's very hard to reach all of them in person. But the videos are three to five minutes long. Those volunteers are looking at a B block and reporting if there are new nests being created, what materials are being used, and which of the six different size holes that they're building in. So the protocols aren't difficult to follow, but sometimes identifying material or getting out each time is the challenge. I would say that the most difficult level is identifying bumblebees. So these volunteers have a full day training, a six hour a day, just learning bumblebee species. There are about 20 species in Minnesota. Some of them are pretty obvious once you know what to look for and some of them you have to look a bit more closely. But those are amazingly dedicated volunteers. There are always a handful who leave a workshop going. Oh, I hope that's, I just no idea whose minds are kind of blown but then I would say 75% in the leave and are just excited to go out and start looking for bumblebee's you know do you ever run into situations where you know you get used photos on i-naturalist and it's just like a blob of yellow and black it does happen or you can't one's head and you know for bumblebees it's what colors the hair on the top of their head what colors or you know what are the bands and the abdomen look like Really, having multiple views is important and a lot of people are just, I mean, when I started, you just get excited, I have a picture and it's in focus. That feels like a question achievement before you realize what angle you should be taking are multiple angles or I need to see these features. Yeah, I can picture that being very important for the IDing process. We also get a fair number of wasps and flies submitted who may have similar color patterns. or... Flies? Mm-hmm. There are some flies that just, we just have black and yellow stripes and so in people's heads automatically that goes to be and there are some flies that are very tricky mimics of these, particularly bumblebees. They're just around, they're black and yellow, they're really, really fuzzy. I did not know that. Mind-blown kind of. Yeah. That is. My job is pretty steep. I've accumulated a lot of nice. knowledge in that time. As for yourself, I mean, how did you get involved with bees? Has it been a thing you've always wanted to get into, or is just kind of something that fell into your path, per se? Sort of a combination of both. Previous to working with Extension, I was an educator at the Belmeseeum of Natural History who pioneered honeybee programs for the state and used being honeybees to talk talk about different social relationships, bringing students into hives to work with them. So I have been a hobby bee honey beekeeper, or I did it for about four years. I kept my hives in Wisconsin at my parents' house. Now actually my dad has gotten so excited. He loves it, so he's taken over, which is great because he actually lives there and I have to drive two hours to get there. So I have this background with honeybees, which turns out they're very different from native bees. I had experience teaching adults, working with volunteers. So those skills transfer great easily. Okay. Are you feeling hopeful? Are you feeling concerned about the state of bees? And has this project kind of giving you a better insight into this? that situation? Sure. I would say to feel pretty optimistic. We might not be in a great spot now, but there are so many people who are getting excited and so many people who are starting to change their habits, who are gardening differently, doing their landscaping. And everywhere I go and meet new people, they ask what I do when I explain, they all go, wow, well, that's so cool. But no one has ever said, that job sounds really boring. Or, I can't believe you guys spent all that money on bees. But, like, everybody thinks it's this neat thing and who wishes they either knew more or could do more about it. So in that, so we're working with the public. Certainly, I feel optimistic. But also, there's some being real with it, right, to know, oh, wow, pesticides really are a problem. Or I've got a lot of people who anecdotally want to tell me, you know, when I was a kid, we had all these bees around our apple trees. And now I only see a couple. And I don't have that perspective, not having lived in Minnesota that long. And so these people are remembering things from 34 years ago. So in that regard, it's why. well, what was it like before? I certainly see more bees now just because I know to look for them and I know what they look like. To realize, oh, there actually are bees on all the time. What I would have said before this draft, well, I don't know. Yeah, maybe I saw bumblebee two weeks ago. Knowing what to see just makes you see a lot more. I guess my final question would be. you know, how does someone get involved with the program or if someone's just really curious about bees in their local area, you know, what are, with some advice you have for people that, you know, kind of just want to get involved with bees and don't really know where to start? Sure. In terms of looking for bees, there are a couple of great books out there just to understand what are the essential characters. six of bee when are you seeing a bee when are you seeing a wasp a fly color is not necessary helpful there are green bees and there are green flies there are black and yellow striped bees they're black and yellow striped was so the two books earlier like are the bees in your backyard and then I'm gonna look at the title here bees an identification and native plant forage guide it's really long but that is specific to the Midwest area So knowing what to look for and then thinking about how you garden and how you can be gardening in a way that supports them. It doesn't have to mean pull out your entire yard and plant it all with native plants, right? That's difficult, that's overwhelming. You might want some of your lawn to actually be your yard for grilling your kids, whatever. But as I've noticed even in my urban lot in St. Paul, that as I've noticed, add features as I have some open spaces with dirt as I leave perennial stems up as I add native plants that I see more bees in my yard. So once you want to look for and you can start seeing them then you can see the changes that you're making and how to make a difference. Outside of your own backyard and maybe looking up information and finding those resources that could help you shape you know your thoughts on how you want to go forward with your own space. Are there certain groups that, you know, that are kind of statewide or regional -wide that are be focused? Yeah, they're a handful. I mean, I think one really important group to follow is the Xerces Society. So they are just covering invertebrates broadly, but they were the driving force behind, excuse me, getting the Rosty Patch bumblebee listed as a federal endangered species. So, I mean, they have information for the public, for homeowners. They also have scientists who are collecting data and a citizen science program just looking at photos of bumblebees. So they were able to document this decline in range, the decline in numbers, and then petition the U.S. fish and wildlife service to get the rusty patch bum will be listed. So they really have their fingers and the pulse of what's going on and are able to take action. Okay. Is there like local chapters or that's kind of just statewide nationwide thing? Yeah, it's a nationwide, or North American. Okay. All right. In our certainly groups in that there are different chapters of wild ones and so they're about native gardening and they have quite a bit of information but pollinators and you get to meet other like-minded people there are tons of honey beekeeping clubs right which are a little different because that's primarily on beekeeper keep the bees over winter get more honey those sorts of things but there Minnesota is when it comes to political advocacy and pollinators the past legislative session, all the bills related to pollinators did fail, but there are huge numbers of people who are lobbying for different treatments of pesticides, of knee-winix noise, different rules around roadside mowing. So that is certainly an area that you could get involved in. Thank you for listening to this episode of The Naturalist.
