it's often good to take a view from another perspective, isn't it? (this time, a tree canopy from the ground, up) another upward, bug-like perspective of a tree... this time, of a sugar maple (acer saccharum) that has shed maybe half its leaves

some days, being a scientist means leak testing stemflow collars all damn day. other days, to be a scientist is to caulk stemflow collars all damn day. 🙂🧪
pins mark the leaks. I ran out of pins. is that a tipping bucket rain gauge in the background? one of 200 in this field? yes, it is.

Saw this beautiful foamy beech today in the forest. This is caused by stemflow, water runoff along the stem of the #tree, and the chemicals on the bark the water collects, creating a soapy foam.

'Bark Bubbles'

Foamy stemflow on a tree trunk is a natural phenomenon apparently - see #AltText

Spied some this afternoon. If you look closely you'll see me reflected in lots of bubbles!

This photo is a detailed, macro image of tree bark featuring a prominent white, frothy substance amidst a vibrant growth of yellow lichen. The majority of the frame is dominated by a bright, chartreuse to golden-yellow crustose lichen, likely a species of Candelariella or Chrysothrix, which grows in dense, granular patches across the dark bark surface. There are also patches of paler grey-green lichen and some darker green moss visible, particularly in the lower portion of the image. The bark itself provides a dark, heavily textured backdrop, with deep furrows and ridges, appearing damp and dark brown or nearly black in colour. This contrast makes the bright yellow and white elements stand out vividly. Centered in the upper middle of the image is an accumulation of white, soap-like bubbles. This natural foam is often a result of "stemflow mixing," where rainwater mixes with dust and plant residues (saponins) on the bark to form a crude soap that froths up as it flows down the textured trunk. The macro perspective emphasises the intricate textures of the organic growths and the bubbly structure of the foam. The image appears well-lit by natural light that highlights the bright colours and dampness of the scene.

🌳💧 Urban trees as stormwater allies?

Stemflow (rainwater running down tree trunks) could be tapped to reduce runoff and irrigate city gardens.

With low-cost retrofits, cities can divert this nutrient-rich water to where it's needed most.

A foaming tree - this one a sweet chestnut. Soapy stemflow like this isn't uncommon when it rains after drought, & tends to be foamy in trees with deep bark grooves which create turbulence. Effectively plant chemicals, pollutants & insect residues are being washed away.

Epiphytic lichens play an important role in stemming the flow of water and nutrients from riparian ecosystems. They capture stemflow before it can be absorbed by tree roots . Water absorption by lichens is immediate, but release is much slower (hours or days). #scottishlichens #riverwoods #lichens
