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

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.

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!

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.

BEAUTIFUL BUCKEYES

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.

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

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.

One of the strongest reasons for not rearing hundreds (or more) Monarchs in close quarters is the spread of the highly contagious parasite OE (Ophryocystis elektroscirrha).

“Ophryocystis elektroscirrha (OE) is a debilitating protozoan parasite that infects Monarchs. Infected adult Monarchs harbor thousands or millions of microscopic OE spores on the outside of their bodies. When dormant spores are scattered onto eggs or milkweed leaves by infected adults, Monarch caterpillars consume the spores, and these parasites then replicate inside the larvae and pupae. Monarchs with severe OE infections can fail to emerge successfully from their pupal stage, either because they become stuck or they are too weak to fully expand their wings. Monarchs with mild OE infections can appear normal but live shorter lives and cannot fly was well as healthy Monarchs.” From Monarch Joint Venture

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?

  1. 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.
  2. Collect immature Monarchs locally from the wild, heeding collection policies on public lands; never buy or ship monarchs.
  3. Raise Monarchs individually and keep rearing containers clean between individuals by using a 20% bleach solution to avoid spreading diseases or mold.
  4. Provide sufficient milkweed including adding fresh milkweed daily.
  5. Keep rearing containers out of direct sunlight and provide a moist (not wet) paper towel or sponge to provide sufficient, not excessive, moisture.
  6. Release Monarchs where they were collected and at appropriate times of year for your area.
  7. Check out Monarch Joint Venture’s newly updated handout, Rearing Monarchs: Why or Why Not?
  8. Participate in community science, including testing the Monarchs you raise for OE and tracking parasitism rates.

HAPPY EARTH DAY ON THIS MOST BEAUTIFUL OF EARTH DAYS!!

“There is symbolic as well as actual beauty in the migration of the birds, the ebb and flow of the tides, the folded bud ready for the spring. There is something infinitely healing in the repeated refrains of nature – the assurance that dawn comes after night, and spring after the winter.”  –Rachel Carson

Dear Friends,

It’s glorious outdoors today and I hope you have a chance to get outside.  See below for photos from my morning Earth Day walk, although I can’t bear to sit at my computer all day when it’s so gorgeous out and will head back out this afternoon to see what we see.

For Earth Day this past week I gave several screenings of Beauty on the Wing (thank you once again most generous community for all your help funding BotWing!) along with presenting “The Hummingbird Habitat Garden” to the Massachusetts Horticultural Society. For over twenty years I have been giving programs on how to create pollinator habitats. People are hungry for real information on how to connect to wildlife and wild habitats and each year the interest grows and grows. It’s truly a joy to witness!

Last night it was especially rewarding to bring Beauty on the Wing to Connecticut’s Sherman Conservation Commission attendees. We had a lively Q and A following the screening with many thoughtful questions and comments. My gratitude and thanks to Michelle MacKinnon for creating the event. She saw the film on PBS and wanted to bring it to her conservation organization. Please let me know if you are interested in hosting a Beauty on the Wing screening.

Monarchs are on the move! The leading edge in the center part of the country is at 39 degrees latitude in Illinois and Kansas: the leading edge along the coast is also at 39 degrees latitude, in Maryland and New Jersey. Cape Ann is located at 43 degrees — it won’t be long!

Monarchs are heading north! Female Monarch depositing egg on Common Milkweed

Hummingbirds have been seen in Mashpee this past week (41 degrees latitude). Don’t forget to put out your hummingbird feeders. Dust them off and give a good cleaning with vinegar and water. Fill with sugar water and clean regularly once installed. The sugar water recipe is one part sugar to four parts water; never replace the sugar with honey, and never use red food coloring.

Happy Glorious Earth Day!

Female Ruby-throated Hummingbird

Super surprised to see this mystery duck asleep on a rock. I was so curious and kept hoping he would wake up so as to identify. He at last lifted his head for all of ten seconds and then  promptly tucked back and went back to sleep. I’ve only ever seen Surf Scoters bobbing around far off shore in the distance. Skunk bird- what a cutie!
