I’ve often mentioned that volunteers are hard at work in every corner of the globe. There is nowhere on the planet where volunteers aren’t involved in some kind of important and impactful work. This story out of New Zealand shows how volunteers there are working hard to remove or at least control an invasive species, wilding conifers. These trees, also called wilding pines, are considered a major threat to ecosystems and biodiversity in New Zealand. Among the organizations dealing with the problem is Environment Canterbury, which is leading events focused solely on removing and controlling the plants.

Volunteers Keep the Invasives Out

People have already started to say that “summer is almost over,” but I’m not ready to go there just yet. It’s still the middle of summer in my mind, the perfect time to be having summer adventures and vacations. One of the most popular activities during the summer is taking the boat out to the local lakes and rivers. When people take their boats far from home, to more distant bodies of water, this can become a serious problem. Invasive species can hitch a ride on those boats and travel with them to other lakes and rivers, finding new  homes there. When they do, they can disrupt and even take over ecosystems, with potentially disastrous results. To prevent this from happening, many boat launches host volunteers who work to remove invasive species before the boats hit the water. This story out of Michigan is just one example of how volunteers are working to keep invasive species off the boats and out of the water. There are numerous programs like this, from the Clean Boats, Clean Waters program in Wisconsin to the GREAT Boaters Program in Rhode Island. All of these efforts, with volunteers at the forefront, go a long way towards reducing the potential for serious ecological problems caused by invasive species.

Volunteers Working with Rangers

Through the Trees

by Robert Barossi

I found out this morning that today is World Ranger Day. Along with environmental volunteers, Park Rangers are on the front lines of conservation efforts around the world. Rangers do a wide variety of jobs, including many tasks which are directly related to environmental protection and preservation. They are often, if not always, the ones who train and lead the volunteers who work alongside them.

There are numerous examples of volunteers and rangers working together. Here are just a few of them that popped up this morning: In Wyoming, both volunteers and rangers work to keep people using the parks safe. In Tennessee, volunteers are working alongside rangers to remove invasive species. The same kind of work is happening in Great Britain. A volunteer in this story from North Carolina notes that the volunteers support and assist the rangers by doing “necessary work that the park rangers don’t have time to accomplish.” And on the Delaware River, rangers and volunteers worked side-by-side to clean up the river during a large annual cleanup event.

Volunteers, Beavers and Goats

An environmental volunteer, a beaver and a goat walk into a bar…Ok, it’s not really the beginning of a joke. It’s actually the beginning of an environmental volunteer story out of Oregon featuring volunteers and goats working to help the local beaver population. When invasive species started taking over the beaver’s home, a local environmental organization brought in goats to deal with the problem. The group, Beaver Environmental Advocacy Volunteers (B.E.A.V.), rented 34 goats, who have been efficiently removing the unwanted plants. Once the goats’ work is done, the humans will continue to do whatever they can to help keep the beavers healthy and thriving. The young organization is a great example of how volunteers can  work together (and with other species, like goats) to figure out ways to coexist with wildlife, rather than trying to simply remove it.

One sentence in particular caught  my eye when reading this environmental volunteer story: “REEF volunteers armed with filleting knives sliced up the carcasses, carefully avoiding the fish’s venomous spines.”

How can you read that and not want to see what these volunteers are up to? In this case, they are working along with the Reef Environmental Education Foundation to reduce populations of invasive lionfish. Check out the story, courtesy of National Geographic, to see just how successful all that knife-wielding volunteer work has been.

Volunteers Under the Mistletoe

The holiday season is without doubt one of my favorite times of year. Whether it’s holiday songs playing on my car’s stereo while navigating snowy streets or houses covered in Christmas lights that fill my neighborhood, I’m a sucker for pretty much anything related to the holiday season. Kissing under the mistletoe is, of course, just one long-standing tradition of the season and this story from San Diego focuses on that famous plant and the legend and lore that surrounds it. It’s also got one of the best titles I’ve seen for a volunteer-related story, “Mistletoe: A Parasite of Peace.” While the article offers lots of information to explain that attention-catching title, it also focuses on a group of volunteers, the Canyoneers. This group of dedicated and passionate volunteers work with the San Diego Natural History Museum and lead area hikes and, every year, sell mistletoe to raise money for their nature programs. Gathering and selling the plant is a holiday season tradition for these volunteers, one that helps them fund some of the great work they do all year round.

More information here on San Diego’s Natural History Museum

Just for fun, a couple of resources I found about the lore and legend of mistletoe, form The Farmer’s Almanac, Smithsonian Magazine and The History Channel

Volunteers Lead the Fight Against Invaders

The “invaders” are invasive species and they are becoming more and more widespread all the time. Climate change is not helping matters, pushing and changing the boundaries of where species can live and thrive. This story out of Rhode Island details a number of ways that volunteers in southern New England are taking part in the struggle to hold back or eliminate invasive species. As the title suggests, it often takes “patience and creativity,” two of the many attributes volunteers bring to the ongoing efforts to deal with a problem that can seem insurmountable.

A Family of Beetle Ranchers

Today, I’m posting another chapter from my upcoming eBook. Now that I’m putting the finishing touches on it, I hope to have it published and widely available soon. Until then, here’s another chapter, about a mother-daughter team of volunteers who raised beetles as part of a local effort to eliminate the invasive purple loosestrife.

The Family Way: Elizabeth and Samantha Emhardt

Amber waves of grain. Kentucky blue grass. California Redwoods. Unique and iconic plants can identify us, define us and inspire us. They can also deceive us. Driving through many parts of the country, a brightly colored plant can often be seen dominating the landscape, filling the open space with an unmistakably bright purple. Though it may be a beautiful shade of that color, the plant is unfriendly and unwanted. Purple loosestrife is an invasive species that has spread to most of the country and is frequently listed as an invasive or nuisance species. Exploring my home state of Massachusetts, I have encountered it numerous times, causing meadows, fields and wetlands to flame with purple light.

In the small town of Canton, a group of volunteers have joined the struggle to keep that flame from spreading even farther. Elizabeth Emhardt and her daughter Samantha are just two of those volunteers, introduced to the invasive plant by the Neponset River Watershed Association (NepRWA). The watershed association has teamed with a number of other organizations to wage war with the invasive plant, a war that employs a fascinating weapon: a beetle. To this end, volunteers like Elizabeth and Samantha perform an important role by becoming ranchers…beetle ranchers. For Elizabeth, a teacher and mother of two, this was an opportunity to volunteer and get involved, something she says she does as often as possible. For her daughter Samantha, a member of her high school science club and former member of Women in Natural Sciences, it was an exciting chance to engage her lifelong love of science.

 

“We always did fun thing in science, like experiments, and it was always really cool to find out how things worked,” Samantha says.

“Science rocks,” her mother agrees, with a smile. While she didn’t know the dangers of the plant prior to this project, Elizabeth says she did have some experience with purple loosestrife. “I remember driving by wetlands and seeing them solid purple.”

“It’s like an alien plant,” Samantha explains. “It’s not native, it has no natural predators here, so it will choke out all the native plants and wildlife and that’s bad.”

When they began the beetle ranching process, one of Elizabeth’s first questions was about the beetle and its natural predator. “If we are introducing all these beetles into the environment,” she had asked, “What happens with them, do we have to release something else to get these beetles?” The answer had been no, the beetles follow the plant and when the food source dies down, they die down with the food source.

“They only eat that one plant, that’s the only plant they eat,” Samantha adds, before going into an explanation of the beetle ranching process. “So, the first thing we do is we go out into the wetlands and actually dig up root balls of the purple loosestrife and we pot them and we put dirt and fertilizer in and we take eight. You can take eight or sixteen, so we take eight and then when you get home, you put them in a little kiddie swimming pool and fill it with water. You actually grow the purple loosestrife in a little homemade swamp. Then later they get beetles imported from Germany and they have beetle sorting day, which I haven’t been to. You’ll go and pick up ten beetles and they’ll be refrigerated so they are asleep and you put nets over the purple loosestrife so the beetles don’t escape, and you put two beetles, or a couple of beetles, with each plant, and then they have lots of babies, so you end up with way more beetles.”

“When did we release them?” Samantha asks.

“I thought it was kind of early that we released them this year,” her mother answers. “It was late July. You take the whole pot, plant, and there are stakes to help hold the nets up, and the nets also keep the predators out, from eating the beetles. So you take the whole mess, pot, net, stakes, back into the wetlands, take the nets off, pick off any larvae or little beetles and you put the plants back in the wetlands and the beetles just have at it.”

When the three of us spoke, Elizabeth and Samantha had completed the second and final time that they would participate in the beetle ranching program, which had been funded for five years. But both say they would gladly do it again, with Elizabeth commenting that during their most recent experience, the rest of the family got in on the fun.

“This past year, my husband and our thirteen year old son, I asked them if they would come with us and harvest the root balls. It’s really messy, you’re in those swampy wetlands, you’re digging these root balls and they are heavy, dirty clumps and you have to carry them out of the swamp and into a place where you can process them. So I asked my husband and my son to come and help us this year and they said yes, and it’s funny cause now my husband is like, ‘I see that purple loosestrife everywhere.’ So, he’s on board too.”

Samantha agrees that it was fun to share the experience as a family. “I think it’s really cool that we all go out there and harvest the root balls and everyone is doing it and then when we have the nets and the beetle set-up you can just go out and check on them, see how they are doing.”

Having a small swamp in their backyard, Elizabeth says, provided lots of opportunity for conversation and sharing the experience with family and friends. “We have a swimming pool in our backyard; we like to entertain a lot. We had this thing in our backyard, it’s a big kiddie pool with eight five gallon pots in it in your backyard with stakes and nets and sometimes it gets a little smelly cause in a sense you’re making a swamp in your backyard. It’s gotta be in a real sunny spot cause the purple loosestrife grows in the wetlands where there’s no trees or shade or anything. I mean, you can’t miss this thing in your backyard, so it gave us a lot of opportunities to talk about what we were doing, what this plant is and what the goal was, how we were ranching beetles.”

Since the project ended, Elizabeth says she has seen tangible evidence of success. “I have gone back and seen less purpose loosestrife. I noticed a spot in Canton that a couple of years ago I drove by and it was all purple and I thought it was beautiful and now I drive by and it’s not solid purple anymore. The beetles migrate where the food is and I’ve seen that because the purple loosestrife is not where it was five years ago and to my knowledge no beetles were released there.”

While beetle ranching may be over, there are other projects with the Neponset River Watershed Association and other opportunities to volunteer. Elizabeth mentions an upcoming river cleanup, “pulling tires and shopping carts and things like that out of the actual river.” She adds that she’d like her husband to go with her but she doesn’t sound sure that he will. “Well, you’re working full time, you have two kids, and the house always needs work done. You know, the lawn, he’s involved in boy scouts, he just moved from the finance committee to school committee. So, we do a lot of things besides work.”

Why then, I ask, did they decide to commit to the beetle ranching project? They both enthusiastically agree that it sounded very cool and interesting, with Samantha adding an excited “Beetles growing in our backyard!”

“It sounded really cool and the biggest time commitment was the day of harvesting, that’s a big commitment,” Elizabeth says. “A lot of people that do the volunteering are people with a lot of time on their hands. People who have a lot of time on their hands are retired people, they can’t physically do this stuff, they can’t go out into the swamps and dig out these root balls. You aren’t just digging out your own eight root balls; we dug out two hundred, over two hundred, root balls. It takes hours, you’re out there and it’s hot and it’s buggy but that’s the big chunk and the rest of it, it’s in your back yard, it’s a lot more manageable.”

In addition, they both felt that they were doing something good for the environment.

“It was kind of fun to help the natural wildlife come back and be restored,” Samantha says, adding, “I might do some more environmental volunteering, it was really cool.”

That environmental interest is something she clearly shares with her mother, who says, “I’m a big time gardener. I love to garden and be outside and spend time outside. I plant plants that I know will purposely draw hummingbirds to my yard. I have a bird bath. I have thistle seed for the goldfinch and house finches and feed for the nuthatch and the tufted titmice. I’ve always enjoyed nature so this whole process appealed to me because there’s a lot of things, the world just shrinks and shrinks, and there’s lot of things invading our environment that don’t belong. There’s a new thing I’m learning about, the Mile-a-Minute vine that’s taking over. The Asian longhorn beetle are destroying trees. It’s just sometimes you feel like…you know, yeah, we’ve got three kids, I’ve got a part time job and am a full time mom, still the major chauffeur in the house. Even though you’re busy with commitments like work and scouts and religious ed. and things of that nature, sometimes I just feel like you gotta help the planet a little bit.”

“Yeah,” Samantha chimes in, “just the little things you can do like recycle everything you can, try to save paper, stuff like that.”

While she does what she can, Samantha also admits that it’s difficult to find time to get outside and enjoy nature. “Sometimes we’ll go for hikes. I don’t know, it’s really busy so it’s kind of hard to get outside, with sports and clubs and homework. I don’t play any sports but a lot of my friends do. I take band so we do a lot of that before and after school. I play the alto saxophone.”

“I think if it was close and easy and convenient it would be a lot easier and more people would get involved,” Samantha says when asked about what might help get more people her age involved in environmental volunteering. Being able to see a tangible result or achievement would also help a lot, she adds, “that would be really cool, like she said, you’re seeing a lot less purple loosestrife.”

Their beetle ranching careers may have ended, but Elizabeth says she will always seek out opportunities to learn about nature and pass that on to her kids. “Not that I’m any natural expert or anything like that but when we are out, if I see something I recognize or know about I’ll always take the opportunity to tell them about it. It’s like, ‘Allright, look, here’s something that you should probably pay attention to.’” While she has learned a lot as an environmental volunteer, much of the knowledge she shares, Elizabeth says, is from when she went camping as a child.

The family continues to camp, she adds. “It’s so relaxing, we have a canoe, once in a while we drag it out, it’s a giant heavy old aluminum canoe, but it will fit all four of us and we paddle around. I get all freaked out and happy when I see a hummingbird moth in our back yard, which is a really funky looking moth-hummingbird thing. I’ll run in the house and say, ‘you guys all have to come out and see this,’ and they just shake their head at me and they’ll come out of the house and we look at this and it’s really cool. Or if it’s raining and the sun is shining and I’ll say, ‘come on we have to go see if there’s a rainbow.’”

That kind of enthusiasm for the natural world has definitely rubbed off on Samantha, who says, “It’s cool, though. I’ve seen so many rainbows.”

Raising Weevils

When I was interviewing volunteers for my book, I spoke to a mother and daughter who were volunteer “beetle ranchers.” They were working with Neponset River Watershed Association to help raise beetles which, when released, would help reduce or eliminate Purple loosestrife in areas along the Neponset River. In this great story from the Shreveport Times, volunteers are part of a similar process down south. Salvinia weevils are being raised in a recently completed greenhouse, one which volunteers helped to construct. The volunteers will also be helping to raise the weevils so that “as many weevils as possible” can be released into “selected areas” of Caddo Lake. The goal is to reduce or eliminate Salvinia, an invasive weed which has been spreading through bodies of water throughout the area.

More information here from the Greater Caddo Lake Association, the lead organization on the project. Also some information on the lake and issues it faces from the Caddo Lake Institute as well as the Giant Salvinia Control Team.

Fighting Invasives in Canada

Invasive species can be more than just a nuisance. They can seriously impact the ecosystem they invade, and those impacts are often, if not usually, negative. They can be detrimental to many other species in the area, including robbing those species of food or other resources. This story focuses on the Clifford E. Lee Nature Sanctuary, not far from the city of Edmonton. Volunteers have been an essential part of the process which has greatly reduced the amount of creeping thistle in the area. One of the story’s many great aspects is the mention of the “invasive species appetizers” volunteers were served, along with recipes to take home with them. Dandelion pesto, anyone?

The Sanctuary’s website is here and here is a link to Nature Conservancy of Canada, which recently hosted the invasive species removal event for the ninth time.
