- (sandstone or basalt?), porous surface
- past twenty years
- encrusted with lichens (both foliose and crustose, pale blue, gray, and green).
- located far from auto traffic, shady spot, but lot of foot traffic. - People stand or sit on it all the time.
Other stone:
granite, smooth surface
- no lichen or other sediment.
- past five years
- people don’t sit on it]]> 2021-07-12 17:44:39 UTC https://padlet.com/lvarelas/pb4tj2ynu97vrwuj/wish/1646208796 Observation T2 lvarelas https://padlet.com/lvarelas/pb4tj2ynu97vrwuj/wish/1646209602 -Rock substrate

Lichens are found mostly found on large/old tree trunks or tree branches like maple, hemlock. Older rocks did appear to have larger lichen and more diversity.
A: Foliose lichen (max. length 8.5 cm) bright green with dark hairs growing on hemlock tree branch
B: Squamulose? lichen (max. length 1.5 cm) in tree trunk (opposite side dominated by )
C & E: Yard pebbles with very tiny light green lichen growth (max. length 0.3- 0.9 cm)
D: Light green semi-circular squamulose? lichen growth in older-looking yard rock (max. length 1.8 cm)
F: Maple tree branch with circular white smooth (4 cm) lichen]]> 2021-07-12 17:46:22 UTC https://padlet.com/lvarelas/pb4tj2ynu97vrwuj/wish/1646210362 Umesh: Observation near CR, ENZI, and Biodiversity buildings@UW https://padlet.com/lvarelas/pb4tj2ynu97vrwuj/wish/1646211261 1) no lichen in newly constructued buildings
2) more lichen near the old buildings, epecially in shaded area
3) structure - boulders
4)substract - have effect on lichen
5) No iichen actually found in any buildings (may be they are removed)

At first I felt unfortunate as to find no sign of lichen on the elderly eastern facing store fronts. I was sure they would exist and that my hypothesis that diameter of lichen I find will directly be related to age of the building. "AHA" I thought, that makes so much sense!, but I could never test this or have proof to support it.

I found that this lack of proof of my hypothesis created many more questions that turned my unfortunate feeling of humility, to an exciting adventure making me late to my meeting.

Can lichens not grow on painted surfaces? Does the ideology of having a nice curbside appeal lead to the destruction of these symbiotes? (Unbeknownst to the owners that the lichens themselves could be beneficial to their environment). Are the buildings too young? How fast do lichen grow?

Apparently lichen on fireplaces was a popular home fashion craze? Limestone fireplace?

- 20 years
- sandstone, with large steel frames around the windows.
- streaks under the windows that look like algae, but close up are sparse, tiny lichen bodies
- areas around the streaks, no such growth
- buildings notorious for poor drainage, so these streaks are probably where rain water runs down]]> 2021-07-12 17:52:11 UTC https://padlet.com/lvarelas/pb4tj2ynu97vrwuj/wish/1646215266 Selectively on columns https://padlet.com/lvarelas/pb4tj2ynu97vrwuj/wish/1646219169 On other buildings, though, the lichens are between the windows, on columns that stand out very slightly from the building face.

Can be moving the lichen or moving the environment through disturbance. Substrates are important. Lighting is important. Moisture is important.
