in the shelter of the covered bridge – lichens on the Benton Bridge

with 7 comments

Some of the species found growing ‘in the shelter of the covered bridge’ are unexpected. The Benton Bridge (Eel River #2) in west-central New Brunswick offered a few surprises.

The Benton Bridge, built in 1927, crosses the Eel River at Benton, York County. The bridge is in an open area of houses, hay fields and a picnic park. A huge lilac at the end of the bridge was busy with hawk mothshttps ( https://janetims.com/2015/06/10/in-the-shelter-of-the-covered-bridge-hummingbird-moths/) . And Stonefly nymphs, an indicator of excellent water quality, covered the boards on the side and end of the bridge ( https://janetims.com/2015/06/08/in-the-shelter-of-the-covered-bridge-stonefly-nymphs/ ). But, to me, the most interesting discovery was on the upstream side of the bridge.

On the north-east facing outside wall, two species of lichen grew:

Boreal oakmoss (Evernia mesomorpha) and burred horsehair (Bryoria furcellata). These are common lichens, usually found on trees in open coniferous woods or on scraggy trees in bogs. Perhaps they like the coolness and humidity offered by this side of the bridge! I am so grateful to Stephen Clayden of the New Brunswick Museum for identifying and commenting on these lichens.
