An Update on the Tree Spotters Beeches

If you’ve been out spotting in the last week or two, you’ve probably noticed some dramatic changes near the Beech Collection. Due to the presence of beech bark disease–compounded by recent periods of drought–many of the Arboretum’s oldest beeches have gone into decline. Caused by an exotic sap-feeding scale insect (Cryptococcus fagisuga) and a secondary […]

Spring into Science! Tree Spotters and TreeVersity at the MIT Citizen Science Fair

MIT citizen science fair

At the Arboretum and across the globe, volunteers are challenging the notion that science happens behind closed doors. Citizen scientists—individuals who contribute their time and efforts towards observation and data collection—are transforming the nature of scientific discovery through their collaborative efforts with professional researchers. Around the world, citizen scientists work alongside professionals in fields ranging […]

Focus on Phenology: Founder’s Fancies

Ribes aureum (Golden Currant)

Phenology–the study of the seasonal rhythm of plants and animals–is a science with deep roots in cultural practices throughout human history. Modern research examines trends in phenological data to help us understand our changing climate, but observation of the timing of biological events has long served social and economic purposes outside the realm of scientific […]

Focus on Phenology: April Ephemera

Crocus vernus (Spring Crocus, Giant Crocus)

Arboretum visitors are not the only ones enjoying this week’s early spring sunshine. Across the grounds, swaths of colorful spring ephemerals have poked their parts above the soil to take advantage of unobstructed access to sunlight. These perennial woodland wildflowers produce stems, leaves and flowers well before the leafing-out of woody understory and canopy species. […]

Honey bee visiting Ozark Witch-hazel (Hamamelis vernalis)

Can you remember February 24, a balmy 73 degree day that brought flocks of visitors to the Arboretum? In the ample sunshine and unseasonably warm temperatures, it felt as though spring had suddenly arrived on the grounds. And indeed, with a week-long spate of warm weather came swelling buds, early-blooming perennials, and honey bees buzzing […]

Fagus grandifolia (American Beech)

There is a slumbering subterranean fire in nature which never goes out, and which no cold can chill. -Henry David Thoreau, A Winter Walk (1843) Winter is upon us, and what better way to beat the indoor-blues than with a crisp afternoon walk through the Arboretum? While autumn’s hues have come and gone, a world […]

Focus on Phenology: Midsummer Marvels

Legumes and loments, cypselas and capsules, samaras and schizocarps! Fruits (in the botanic sense) come in a wide variety of shapes and sizes, many of which can be found growing inconspicuously among the shady canopies of the Arboretum. These hot and hazy summer days mark a critical transition period, as fertilized flowers transform slowly and […]

Focus on Phenology: Captivating Clones

When lilacs last in the dooryard bloom’d, And the great star early droop’d in the western sky in the night, I mourn’d, and yet shall mourn with ever-returning spring. Ever-returning spring, trinity sure to me you bring, Lilac blooming perennial and drooping star in the west, And thought of him I love.       […]
