OUTSTANDING WORK IN PROGRESS BY LOCAL LAND STEWARDS ORGANIZATION CREATING COMMONS COLLECTIVE

Xavier, Lucas, Mark, Nick, Kim, Molly, and Sarah

What a joy to meet these members of Creating Commons Collective, a grassroots organization passionate about developing beautiful, native plants landscapes for our community.

The project at Blackburn traffic circle began last spring.The soli was tilled (with the help of Mass DOT) and the first batch of plants were introduced. The group is selectively adding native flowering plants with the long term goal of creating a self-sustaining, pollinator friendly, native plants meadow.

Sarah mentioned Creating Commons Collective native plants project at Burnham’s Field, which I am very eager to go check out, and Nick shared a recent article “Improvised Landscapes” that he wrote for Arnoldia, the quarterly publication of the Arnold Arboretum. It’s a great read and you can find the link to the article below.

Improvised Landscapes

By Nicholas Anderson April 4, 2023

OVER THE YEARS I have abandoned and inverted my horticultural training, and today, I struggle to describe what I do. When time is short, I simply say that I make meadows with native plants; sometimes I use the term “ecological maximalism.” But definitions don’t really matter when it’s late September, and I’m stopping off at a patch of dirt in Gloucester, Massachusetts, sandwiched between a new housing development and a Market Basket on the edge of a woodland remnant. Just now I don’t particularly need any new plants, as I have a dozen or so ongoing meadow projects that double as plant nurseries, but I can’t resist a salvage mission before going grocery shopping. I walk past orange-painted surveyors’ stakes through one of the spots where I scattered seeds the previous winter. Most of the seedlings have succumbed to the drought, but a few anemic partridge-pea plants (Chamaecrista fasciculata) are visible amidst the tire tracks. This space is used as a parking lot for little league games in the summer and the city deposits untold tons of salty snow here every winter. Remarkably, whorled loosestrife (Lysimachia quadrifolia) and sweet fern (Comptonia peregrina) insist on colonizing into the very spot that gets savaged by the plows year after year. I pull up four rhizomes of the sweet fern and grab two tiny volunteers of winged sumac (Rhus copallinum) before heading over to the other side of the lot, where frost aster (Symphyotrichum pilosum) and oldfield goldenrod (Solidago nemoralis) are in bloom amidst mugwort (Artemisia vulgaris) and tendrils of asian bittersweet (Celastrus orbiculatus). Out of the midst of these introduced species, I yank up twenty-odd plants with tender violence and put them in a wet, plastic bag.

EASTERN MONARCH POPULATION COUNT DOWN FOR OVERWINTERING BUTTERFLIES 2022-2O23

Leave a reply

The presence of the Eastern Monarch population in Mexico’s transvolcanic mountain forests was 22 percent less this winter compared to last winter, according to the World Wildlife Fund (WWF) annual count.

Rather than counting individual butterflies, the Monarchs are counted by the number of hectares they occupy. This past winter, the Monarchs occupied 2.21 hectares, down from 2.84 hectares in 2021-2022. A hectare is approximately 2.47 acres. A threshold of at least 6 hectares is recommended to sustain the eastern population.

For more precise information on how the Monarchs are counted read more from Monarch Joint Venture –

Estimating the Number of Overwintering Monarchs in Mexico

Contributors: Gail Morris, Karen Oberhauser, Lincoln Brower

Every year we anxiously await news of the monarch overwintering population count from Mexico. When are they done and how are the monarchs counted?

Monarchs go through four phases while overwintering in Mexico: their arrival, the establishment of an overwintering colony, colony movement and finally the spring dispersal.

The first fall migrating monarchs usually arrive at the overwintering sites in late October through mid-November. In this early phase, the monarchs are largely scattered and diffuse in their flight, moving frequently through an area and eventually creating small clusters at night, while still continuing to move through the forest. During the day, their movement is common and widespread, as they search for the perfect sheltered location to spend the winter.

As temperatures dip colder, monarchs begin to form larger and denser clusters, settling into smaller and protected areas at elevations of 2900-3300 meters (9,500 to 10,800 feet.) This usually occurs from mid-December through early February and the monarchs principally roost in oyamel trees although they use pines and other trees as well. This is the coldest time of the year where monarchs are most compact and stationary in their clusters, a time of winter survival with little movement.

By mid-February, temperatures are gradually climbing and the monarchs begin expanding their clusters. They slowly begin to move down the mountain on warm, sunny days searching for water to drink in nearby creeks. They return to the safety of the nearby forest as temperatures drop. The final phase is the monarch dispersal as the population gradually begins its movement north.

The traditional time of the annual overwintering count in Mexico is in late December when the clusters are most compact and movement is minimal. So how are the estimates done? How do you estimate how many monarchs there are in an area?

The World Wildlife Fund and the MBBR have measured the monarch population each year since the winter of 2004-2005. The occupied trees are mapped in each colony. Beginning with the highest tree in the periphery, the counters use a measuring tape or distance meter and compass to measure the perimeter using a series of lines connecting trees along the boundary. The enclosed area is then calculated in hectares.

Researchers have estimated that there are approximately 21.1 million butterflies per hectare, although this number most certainly varies with the time of the winter as the colonies contract, expand, and move. It also varies with the density and size of the trees in the colony. Based on this estimate the largest population of monarchs occurred in 1996-1997 when the colonies covered over 18 hectares and contained an estimated 380 million butterflies. To date the lowest population recorded was in 2013-2014 with 0.67 hectares and approximately 14 million monarchs.

While population estimates are recorded back to the winter of 1976-1977, long term counts of monarchs previously occupying the overwintering sites for comparison are limited due to a lack of complete data.

Keep in mind that the monarch overwintering estimates in Mexico are done when the monarchs are most compact in the trees. While counts continue biweekly during the time the monarchs are in the area, the end of December counts are used for comparison from year to year.

MONARCH BUTTERFLY POPULATION STATUS UPDATE AND LOOKING FORWARD TO SCREENING ‘BEAUTY ON THE WING’ IN NEW JERSEY ON SUNDAY!

Leave a reply

A very brief Monarch population status update – For the second year in a row, the Western Monarch population is seeing an uptick in numbers. The population is at roughly at 335,000, up from the historic low of only 2,000 counted in 2020. Two years of relatively good numbers gives us all hope the Western population can be saved.

It appears as though the Eastern Monarch population is not doing quite as well as last year. The final count for the winter of 2022- 2023 is not yet in. We’ll check back in on that count as soon as the graph becomes available.

Sunday afternoon, I’ll be screening Beauty on the Wing at the New Providence Memorial Library in New Jersey. New Providence is only about 20 minutes from my Mom and Aunt’s childhood home and it was at my Grandmother’s gardens where I first fell in love with the natural world.

I am also super excited to share that we will be screening Beauty on the Wing for school children (and grownups) across Prince Edward County on June 23rd. Prince Edward County in on Lake Ontario and is a late summer gathering point for Monarchs before crossing the Lake into the US. The entire long point peninsula on the South Shore of Prince Edward County is a designated International Monarch Butterfly Reserve (established in1995).

“The land area of the IBA (editor’s note- Canadian acronym for Important Bird Areas) is comprised of shallow soil over limestone bedrock with areas of alvar habitat. Much of the habitat consists of old field (savannah) and shrub thickets, with small deciduous and coniferous forests being present. In addition to several natural wetlands, the IBA contains two large wetland areas created after berm construction by Ducks Unlimited. The IBA is important for concentrations of migrating birds, bats and butterflies and also supports several rare vascular plants including Four-leaved Milkweed, Butternut, Bicknell’s Sedge, Short-stalked Chickweed, Brainerd’s Hawthorn, Limestone Hedge-hyssop, Green Arrow-arum, White-tinged Sedge, Eastern Few-fruited Sedge, Ram’s-head Lady’s-slipper, and Carolina Whitlow-grass. Largely undisturbed sites are important to ensure survival of these plants.”

The PEC south shore is also home to the Prince Edward Point Bird Observatory, where a diverse and extraordinary number of birds concentrate during migration.

Climate concerns growing for the future of many migratory species.

We travel all over coastal Massachusetts to learn about a few local “indicator species,” which can help explain the impact of climate change. Award-winning documentarian Kim Smith tells us the story of piping plovers breeding in Massachusetts.

The City of Cambridge raises monarch butterflies for release.

Every year, hundreds of sea turtles are stranded on the Cape. The New England Aquarium’s sea turtle hospital comes to the rescue.

Meanwhile, terrapin turtles on the Cape are struggling to survive.

In Plymouth at Manomet, researchers monitor coastal health, tag songbirds, and study the presence of a mighty migratory shorebird – the whimbrel.

And scientists at Nature and students at Bristol Aggie examine the health of river herring in the Taunton River watershed.

KIM SMITH FILMS ON CHRONICLE, WCVB CHANNEL 5, “WILDLIFE WORRIES” NOVEMBER 9TH, TONIGHT!

Hello Friends,

Our beloved Piping Plovers and Monarchs are going to be featured on an episode of Chronicle this evening. “Wildlife Worries” is devoted entirely to indicator species including not only Monarchs and PiPls, but also Whimbrels, tiny terrapins, and more. The show airs tonight at 7:30pm on Chronicle, WCVB, channel 5.

Several months ago, I met with the outstanding Chronicle producer, Sangita Chandra, and the show’s stellar videographer, Jennifer Platt-Ure. Originally Sangita was looking for footage of Monarchs and PiPls, but then decided to include an interview from a filmmaker’s perspective. The interview was filmed at Winthrop Shores Reservation as it was a convenient location, and also the charming cafe, Piccolo Piatti. It was a joy working with Sangita as she has a keen interest in wildlife conservation. The show promises to be wonderfully educational. I can’t wait to watch the part about the whimsical Whimbrels and turtles, in addition to the PiPls and butterflies!

Chronicle writes, “New England wouldn’t be New England without the shore birds, butterflies, and turtles that spend part of the year here. These and other local creatures are considered ‘indicator species’ that also help us understand the impact of habitat loss and climate change. Tonight we get up close to giant sea turtles and tiny terrapins, whimbrels and piping plovers, and meet the people committed to protecting them.”
.
Included in that group – a park ranger who raises butterflies, a documentary filmmaker, and high schoolers studying river herring. Many thanks to our videography team – Bob Oliver, Jennifer Platt-Ure, and Rich Ward and to editor Ellen Boyce. Hope you enjoy the program!

Thank you so much for watching!

Warmest wishes, xxKim

BEAUTY ON THE WING WINS BEST DOCUMENTARY!

Leave a reply

Dear Monarch Friends,

I am delighted (and very surprised) to share that Beauty on the Wing has won Best Documentary at the San Diego International Children’s Film Festival. I write surprised as there were many beautiful films from around the world participating in the festival, and also because I wasn’t even aware we had been nominated for the award. My sincerest thanks and gratitude to SDIKFF!

Yesterday there were a number of Monarchs out on Eastern Point nectaring at wildflowers and in my garden. It was magical that we learned of the award on the same day as seeing these stragglers. We were celebrating Dia de Muertos here on Plum Street, and on this very same day, November 2nd, Monarchs were spotted arriving at Cerro Pelon and El Rosario Monarch Butterfly sanctuaries. Joel Moreno and his family at Cerro Pelon JM Butterfly BandB spotted the Monarchs traveling high in the sky in the upper thermals while my friend David Hernandez reports that at El Rosario, they are flying low on the mountain.

The wings of the butterfly in the upper photo appear as though they have been snipped by birds while the butterfly’s wings in the second photo are pristine.

Will the stragglers that we see at this time of year be able to travel the roughly 3,000 mile journey all the way to Mexico? I don’t know the answer to that question but we can make a guess that if a butterfly looks weather worn, with torn and tattered wings, it is unlikely that it will be able to complete the journey. On the other hand, some of these late Monarchs that we are seeing look as though they just eclosed (hatched) hours earlier. Their wings are a vibrant orange and black and are completely unscathed. Some butterflies will be funneled between the Appalachian and Great Rockies while others are destined to follow the Atlantic coastline, traveling towards Florida and the Gulf of Mexico states.

Safe travels Monarca, wherever you land!

I hope you are able to get out and enjoy this extraordinarily lovely stretch of balmy weather we are having.

Warmest wishes,

xxKim

Celebrating Day of the Dead

Leave a reply

Inspired by my friend Nina’s beautiful altar that she and her family and friends create every year for the feast of St. Joseph, for the past seven years or so we have been celebrating Día de Muertos with an ofrenda that we set up on our front porch. Placing the ofrenda on the porch over Halloween makes for a wonderful hybrid bridge between American Halloween and the Mexican tradition of honoring the souls of lost loved ones. On Halloween night our porch has become a gathering place where we so very much look forward to seeing our neighborhood friends each year.

Cemetery Macheros, Mexico

The Mexican festivities of Día de Muertos typically begins the night of October 31st, with families sitting vigil at grave sites. Mexican tradition holds that on November 1st and 2nd, the dead awaken to reconnect and celebrate with their living family and friends; on the 1st to honor the souls of children and on the 2nd, to honor adults. The ofrenda, or “offering to the dead,” is a sacred Mexican tradition where those who have passed away are honored by the living.

In late October millions of Monarchs begin to arrive to the magnificent oyamel fir and pine tree forests of the Trans-Mexican Volcanic Belt, located in the heart of Mexico in the eastern regions of Michoacán and western edge of Estado de México. Their return coincides with the annual celebration of Día de Muertos. In Mexican folklore, butterflies represent the souls of departed loved ones, returning to Earth to be remembered by their ancestors. An even older tradition connects the Monarchs with the corn harvest, as their return signified that the corn was ripe. In the language of the native Purpécha Indians, the name for the Monarch is “harvester.”

The Day of the Dead finds its roots in the native people of central and southern Mexico. The Aztecs recognized many gods, including a goddess of death and the underworld named Mictecacihuatl.

Mictecacihuatl was linked to both death and resurrection. According to one myth, Mictecacihuatl and her husband collected bones so that they might be returned to the land of the living and restored by the gods. Just as did the ancient Egyptians, the Aztecs appeased the underworld gods by burying their dead with food and precious objects.

Día de Muertos is a celebration blending both indigenous people’s cultural beliefs and observances held by Spanish Catholics. The conquerors found it difficult to convince native peoples to give up their rituals honoring the goddess of death Mictecihuatl. The compromise was to move these indigenous festivities from late July to early November to correspond with the three-day Christian observance of All Saints’ Eve, All Saints’ Day and All Souls’ Day.

This year I have been thinking about Camille Saint-Saëns’s Danse macabre, Op. 40, which is based on the French legend that Death packs a fiddle and comes to play at midnight on Halloween, causing the skeletons in the cemetery to crawl out of the ground for their annual graveyard dance party.

Saint-Saëns’s Danse macabre comes from an even older concept, the medieval allegory of the all conquering and equalizing power of death, which was expressed in poetry, music, the visual arts, and drama in Western Europe in the late Middle Ages.

BEAUTIFUL BUCKEYES

Leave a reply

A truly glorious weekend weather-wise with warm sun, mild temperatures, beautiful sunrises and sunsets. There are still loads of butterflies on the wing. Saturday was a five species afternoon, not an everyday occurrence in mid-October on Cape Ann. Monarchs were on the move, along with American Ladies, Clouded Sulphurs, Orange Sulphurs, and one of my favorites, the wholly uncommon, Common Buckeye. The gloriously patterned 3 pairs of eyespots of the Common Buckeye are meant to frighten avian predators, a scary six-eyed monster if you will, but we humans find them enchanting.

Each summer Common Buckeyes emigrate to New England from southern states. Some years we see many more than others. It’s always a delight to come upon one and I typically find them at the edge of a marsh nectaring at Seaside Goldenrod or basking in the sun on a sandy path.

A MINI- GLOSSARY OF LATE SUMMER BUTTERFLIES

Buckeyes begin around 2:40

Common Buckeye Larval Host Plants

Female Common Buckeyes deposit their eggs on a variety of plants, both native and non-native.

Caterpillar food plants from Mass Audubon –

Many documented. In the Northeast, larvae usually feed on “members of the snapdragon family (and) plantain family” (Opler and Krizek, 1984), including Blue Toadflax (Linaria canadensis); False Foxglove and gerardias (Gerardia, species), plantains (Plantago, sp.), and Snapdragon (Antirrhinum). Buckeye larvae have been observed in Massachusetts on Butter and eggs (Linaria vulgaris) and Slender Gerardia (Gerardia tenuifolia)

And from The Butterflies of Massachusetts

Today, lacking such an abundance of gerardia, Common Buckeye’s most usual host plant in Massachusetts may be Plantago lanceolata, or lance-leaved plantain, a widespread non-native weed introduced with the arrival of European settlers. The 1990-95 Connecticut Atlas workers observed Buckeye ovipositing on lance-leaved plantain in the wild, and the caterpillars have been successfully raised on it many times, for example by caterpillar photographer Sam Jaffe in July 2011. Buckeyes have been observed in the wild ovipositing on the native purslane speedwell (Veronica peregrina) (S. Jaffe 6/21/2011), and on the non-native butter-and-eggs (Linaria vulgaris) (M. Champagne 7/14/2008). They are also reported to use blue toadflax (Linaria canadensis), slender gerardia (Agalinis tenuifolia), and sometimes non-native garden snapdragons (Antirrhinum majus) (Scott 1986).

GUIDELINES ON HOW TO RESPONSIBLY RAISE MONARCHS

Leave a reply

The first guideline in becoming an excellent citizen scientist is to do no harm while trying to do good. Considering the spiraling downward numbers of the Monarch Butterfly population, this basic tenet has never rang more true.

A number of friends have written in the past month with questions about captive rearing butterflies and the new listing of the Monarch as an endangered species by the IUCN (International Union for the Conservation of Nature) and by the state of California. The ruling by the IUCN, which is an organization based in Gland, Switzerland, has no bearing on rearing Monarchs however, that is not the case with the California ruling.

In June, a California court ruling opened the door for the protection of insects as endangered species, which now includes the Monarch Butterfly. It is unlawful to take possession of live monarchs, breed and rear them in captivity, and conduct other interventions including covering eggs, larvae, and adult butterflies with nets, and transporting Monarchs to different locations. Canada and Mexico also restrict Monarch handling.

The ruling is understandable. There are folks who are rearing Monarchs by the hundreds, thousands, and even tens of thousands in wholly unsatisfactory conditions, ignoring safe and sanitary protocols.

As goes California, so goes the rest of the nation. I am deeply saddened that it won’t be long before we in the rest of the country will also no longer be able to rear Monarchs even on the most modest scale.

Simply put, the very best way to help Monarchs is to create pollinator habitats on whatever scale you can manage. Plant milkweeds native to your region, which provides food for the caterpillars.* Plant native wildflowers such as New England Asters, Seaside Goldenrod, and Joe-pye, which provide sustenance to migrating Monarchs and a host of other pollinators. Plant annuals native to Mexico with simple, uncomplicated structures, such as single (not double) Zinnias, Cosmos, and Mexican Sunflowers (Tithonia), which will bring the pollinators into the garden and provide sustenance throughout much of the growing season, while the pollinators are on the wing.

Plants such as daylilies, roses, and dahlias are eye candy for humans. Keep your eye candy plants to a minimum and know that they are just that, eye candy. They do not help pollinators in any way, shape, or form.

A Monarch in the wild flits from plant to plant and from leaf to leaf when looking for a suitable milkweed plant on which to deposit her eggs. She is carefully inspecting each leaf, first scratching the surface with her feet, the butterfly’s way of sensing taste. The female will typically deposit no more than one egg or possibly two eggs per leaf or bud. When you see an image of a large cluster of Monarch eggs, you can be sure the female was raised in close quarters in captivity and is desperate to deposit her eggs.

Recommendations from the Xerces Society:

How can I rear monarchs responsibly?

Rear no more than ten Monarchs per year (whether by a single individual or family). This is the same number recommended in the original petition to list the monarch under the Federal Endangered Species Act.
Collect immature Monarchs locally from the wild, heeding collection policies on public lands; never buy or ship monarchs.
Raise Monarchs individually and keep rearing containers clean between individuals by using a 20% bleach solution to avoid spreading diseases or mold.
Provide sufficient milkweed including adding fresh milkweed daily.
Keep rearing containers out of direct sunlight and provide a moist (not wet) paper towel or sponge to provide sufficient, not excessive, moisture.
Release Monarchs where they were collected and at appropriate times of year for your area.
Check out Monarch Joint Venture’s newly updated handout, Rearing Monarchs: Why or Why Not?
Participate in community science, including testing the Monarchs you raise for OE and tracking parasitism rates.
