March & early April in the forest summarized: all recent Springs have been a different kind of mess and this one is too! Late and early Spring species collide in the heated atmosphere.

Wingless ground beetles, who need not heat any flight muscle and therefore tolerate cold temperature foraged less than normal, while all sorts of unexpected heat-loving bees and wasps are buzzing around ! I do not know what plants feed them. They woke up in primroses season, i.e. way ahead of vegetation.

And Oaks start displaying their shoots 1 month ahead of schedule, at a time when night frosts can still bite them!

Trillium by the thousands today in Prairie Creek Redwoods State Park. The weather was warm enough for snakes to be out along the trails.

A warm day today in the redwood forest. Trillium were prominent, with colors ranging from white to pink to purple. This is a close-up view of a white trillium in Prairie Creek Redwoods State Park. Egg-yolk yellow anthers can be seen in the center of the flower. The shadow of the trillium falls on its green leaves.

Dear Friends,
These two trees, a beech on the left, a walnut on the right have been objects of admiration for some time.

Yesterday, the sky was this gray.

Recalling this moment -
the cool air moving above and around,
through my nose, into my lungs, then back out
head upward - breathe, click, breathe.

Stating the obvious - all of this is a miracle.

The branches of a Beech tree with early signs of flowering and the still bare branches of walnut tree are silhouetted against a cloudy, solidly gray sky.

Phenology (Climatology 🌍)

Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors. Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of migratory birds, the date of leaf colouring and...

“But Thoreau also knows that the calendar, like Emerson's "tradition," has hardened into a formal and highly abstracted system, and that its present lines of demarcation are arbitrary. As categories of perception, neither the months nor the seasons, traditionally demarcated, are responsive to nature's actual currents of change because they have become distanced from perception, which no longer informs them.“

from Thoreau’s Morning Work by Daniel Peck

“They go publishing the ‘chronological cycles’ and ‘movable festivals of the Church’ and the like, but how insignificant are these compared with the annual phenomena of your life, which fall within your experience! The signs of the zodiac are not nearly of that significance to me that the sight of a dead sucker in the spring is. That is the occasion for an immovable festival in my church. Another kind of lent.”

the first skunk cabbages of the season; this day marks the beginning of my calendar

I want to know when and where events like this occur in my place, to mark and celebrate the first skunk cabbage emerging from the ice and the start of spring, the first leaf unfurled on the beech outside my door, etc.

I have had many false starts over the years trying to keep a record of these occasions but I keep trying and will likely continue

a skunk cabbage shoot pushing up through mud and ice. There is mud stuck to the side and dead leaves and twigs behind it in a patch of melted snow.
Just the tip of a skunk cabbage shoot emerging through the ice. A forested and snowy hillside is in the background, a decaying leaf and fallen branch are in the foreground framing the shoot.
