May 22: Daybook for the Year in Yellow Springs

For the past 36 years, I have kept records of weather and the progress of the seasons in Yellow Springs Ohio, a small town just south of the 40th Parallel in the Ohio Valley. Whenever I travel in the United States or even to Italy, where my youngest daughter lives, I add notes about what is happening in the places I visit or pass through.

The daybook has been an anchor in my personal life, becoming a kind of autobiography of my awareness of the natural world around me. And since there are few resources for comparative phenology in print or on the web, I feel that my daily notes might be of use to those interested in following common events in the Ohio Valley seasons, and in contrasting those things with what is happening in their own neighborhoods.

May 22nd

The 142nd Day of the Year

The flowering of wild grapes seems to me always a time of demarcation – on the one side, the halcyon days and nights of migrant and courting birds with their wealth of song, the choirs of the frogs, the stimulating aromas and odors of the opening earth – and on the other side, the months of humidity, mosquitoes, deer flies, and gnats, making the marshes less pleasant for walking.

Today’s Weather

The likelihood of precipitation rises sharply to over 50 percent, but temperatures are typically warm: 80s on 40 percent of the days, 35 percent in the 70s, a fourth of the days in the 60s. The sun shows through the clouds three days out of four.

The Weather in the Week Ahead

The final week of May is typically a wet one, with completely overcast conditions more common than during any other time of the month. On the 25th, 26th and 27th rain falls almost half the time, and the 29th is one of the rainiest days in the whole year. Average temperature distribution for this time of the month is as follows: five percent chance for highs in the 90s, thirty percent for 80s, thirty percent for 70s, twenty-five percent for 60s, and ten percent for 50s. The brightest days of the week are usually the 27th and 30th.

Natural Calendar

The last week of late spring (the last week of May at average elevations along the 40th Parallel) offers the best of Honeysuckle Blooming Season and Sweet William Season. It’s Multiflora Rose Blooming Season, Siberian Iris Blooming Season, Privet Blooming Season, Yellow Poplar Blooming Season and Spiderwort Season. In the woods, Gold-Collared Blackfly Season and Green Six-Spotted Tiger Beetle Season have started. Along bikepaths and old railroad right-of-ways, it is Blackberry Blooming Season and Black Raspberry Blooming Season. In the garden, Leafhopper Season and Scorpion Fly Season open. Grasshopper Season and Northern Spring Field Cricket Season bring the fields alive. Butterfly seasons include White-Spotted Skipper Season and Red Admiral Season. It’s Fledgling Robin Season in the yard, Young Groundhog Season in the fresh grass along the highways.

Notes for the Yellow Springs News on the Possible Effects of Global Warming in Yellow Springs – 2007

Bruce Stutz’s Chasing Spring notes that the growing season in Europe now begins eight days earlier than it did in 1970 and that North American tree swallows lay eggs nine days earlier than they did in 1959. “Worldwide studies of more than 1,500 species,” says Stutz, “show that frogs mate, birds nest, and trees bud on the average more than a week earlier than they did 50 years ago.”

Reports this year from places as diverse as the Shanghai Botanical Gardens and the New York Botanical Gardens emphasize the unusual nature of this past winter-spring season. The first four months of 2007 in Yellow Springs brought extremely early blooming of trees and perennials – as well an unfortunate freeze that produced the only April in recent memory without significant color from redbuds and crabapples.

And that was enough of a surprise to send me to my daybook to look for more evidence that our climate might be in flux. Although my phenological records of the past quarter century in Yellow Springs are not exactly rigorous (I did not record blooming or leafing dates for many species some years), they offer an interesting perspective on blossoming times since the early 1980s.

To test the hypothesis that some flora are flowering earlier than they did 25 years ago, I checked my first blooming dates for common shrubs that grow in my yard, shrubs for which I have the best records: forsythia, redbuds and mock orange.

I recorded the first flowers of forsythia as early as February 25 in 1998 and as late as April 3 in 2001, with March 25 the mean blooming date. Among the earliest years, 3 occurred in this century, 4 in the 1990s and 3 in the 1980s. Among the latest years, 3 occurred in this century, none occurred in the 1990s, and 6 occurred in the 1980s and 1970s. Although an easy progression was not clearly visible, more forsythia have bloomed before March 25 since 1990.

I came up with similar results when I checked my notes on redbud blooms. While earliest flowers occurred as early as March 17 in 1990 and as late as April 21 in 1989, with the mean of April 13, almost all of the earlier flowering occurred after 1990.

Most striking because they displayed the clearest progression were my notes on first blooming dates for mock orange. The earliest day I have recorded for mock orange is May 5 in both 2006 and 2000. The latest date is May 25 in 1984, with the mean being May 15. Ten out of 12 of the earlier dates occurred after 1990. Seven out of 12 of the later dates occurred before 1990.

The results of this unofficial overview? Yellow Springs may be experiencing the same kind of changes already noted in so many other locations. Even though every spring is different, it appears that 1)  forsythia is more likely to flower before March 25 than it was in the 1980s), 2) redbuds are more likely to flower before April 13 than they were in the 1980s, and 3) mock orange bushes are more likely to bloom around May 8 instead of around May 18, the expected average date in the middle 1980s.

2008: Yellow roses early to mid bloom at Liz’s yard. The air along Stafford Street is heavy with the scent of locust flowers, the high trees white with blossoms. One cardinal sang outside our window this morning at 3:50. No red-bellied woodpeckers today. The top few inches of three Jerusalem artichokes in the garden had been eaten off overnight by a deer. Violet locust tree in bloom at Stutzman’s nusery. Pond iris budding. On the way to Wilmington and back, great patches of ivory locust blossoms, some entire woodlots in bloom. Pineapple weed (matricaria discoidea) seen at school – years ago I had identified it as chamomile. Jeanie cut back the New England  asters today. Blue-flowered bittersweet nightshade seen in bloom along High Street. Four Dutch iris in bloom today in the north garden. Berries fully formed on the hackberry, Osage budded. Robin singsong at dusk.

2009: Kousa dogwood opens as the hawthorn ends. American beech now fully leafed.

2010: Cedar waxwings feeding in the mulberry tree late this morning, robins peeping to their young, toad singing in the pond, red admiral butterfly in the circle garden, sun coming through the clouds, cool northwest wind. Water iris fully budded. A male tiger  swallowtail came by. Porch wisteria fading, some yucca six-feet tall. Lamb’s ear full bloom, many crab apples full size.

Strawberries are still in bloom, only a few with berries, all green. A male Baltimore oriole appeared in the north honeysuckle hedge this afternoon, the second one this year. And a pair of orioles reported along the road to Fairborn.
