Rare lichen monitoring

    Hello Northwest Lichenologists,


    I've recently stared as the Washington Natural Heritage Botanist and I'm looking forward to updating the rare lichens list for WA in collaboration with NWL in the near future.


    One major challenge of understanding our rare lichens is that many populations haven't been monitored since they were discovered, sometimes decades ago.


    I have been thinking about what lichens might be the most important species to focus future monitoring efforts in Washington. Personally, I am most interested in lichens that occur in ecosystems where there are potential threats related to management and land use, but I am interested in any suggestions.


    So I ask you, gentle lichenologists: what lichen species do you think might benefit most from future monitoring efforts?


    Yours in Science,
    Jesse

    Hey Jesse, this is great news and I'm looking forward to seeing this come to fruition. I'd love to get involved! Some species that come to mind are:


    -Texosporium sancti-jacobi (sage-steppe bunchgrasses, threatened by grazing and invasive annual grasses)


    -Tholurna dissimilis (high-elevation krummholz, many CNALH observations near trails and ski areas)


    -Acroscyphus sphaerophoroides (only 1 CNALH obs., potential new obs. in E Olympics per iNat)


    -Pseudocyphellaria hawaiiensis (riparian w/ heavy marine influence, could be sensitive to our recent climate extremes and recreational development)


    -Umbilicaria lambii (NW NA endemic, alpine/subalpine, could be affected by increasing trend in casual mountaineering)


    -Umbilicaria phaea var. coccinea (NW endemic, potentially underrepresented, seems to be at fairly low elevations in WA which could lead to more impacts)


    It's too bad that so many of these rare species haven't been checked on in so long. I wonder if Rarecare would consider adding a rare lichen component to their monitoring program. Maybe that could help establish more consistent check-ins on known populations. Lalita's lichenology students could potentially help with monitoring, especially the more accessible populations.


    Thanks for making this one of your priorities in your new position!

    Ryan, thanks for sharing these thoughts--very helpful! I'll keep these species in mind.
