      All:

      As part of a large National Park Service Project we will be surveying alpine areas from the Southern Rockies and Sierra's up into Alaska.  Since the bee season varies in alpine systems so greatly among years and localities we are trying to slice out a relatively similar phenological window to do surveys.  We are thinking that it would be useful to use some set of early season flowers as a flag to when surveys should begin.

      So are questions are:

      1.  Does this make sense?
      2.  What set of flowers could be used that would encompass that geographic range and capture about the same window?
      3.  Do you have alternative suggestions or see potential problems?

      Thank you.

      I can say now that nothing was possible
      But leaving the house and standing in front of it, staring
      As long as I could into the valley. I knew that a train,
      Trailing a scarf of smoke, would arrive, that soon it would rain.
      A frieze of clouds lowered a shadow over the town,
      And a driving wind flattened the meadows that swept
      Beyond the olive trees and banks of hollyhock and rose.
      The air smelled sweet, and a girl was waving a stick
      At some crows so far away they seemed like flies.
      Her mother, wearing a cape and shawl, shielded her eyes.
      I wondered from what, since there was no sun. Then someone
      Appeared and said, "Look at those clouds forming a wall, those crows
      Falling out of the sky, those fields, pale green, green-yellow,
      Rolling away, and that girl and her mother, waving goodbye."
      In a moment the sky was stained with a reddish haze,
      And the person beside me was running away. It was dusk,
      The lights of the town were coming on, and I saw, dimly at first,
      Close to the graveyard bound by rows of cypress bending down,

      The girl and her mother, next to each other,
      Smoking, grinding their heels into the ground.

        Mertensia oblongifolia (Nutt.) G. Don or another Mertensia species


        Maybe Tetraneuris (Hymenoxys) grandiflora (Torr. & A. Gray ex A. Gray) K.F. Parker, although this is more mid-season than early. Easy to spot when it's in bloom.


        3.  Do you have alternative suggestions or see potential problems?

        I have data since 1973 on flowering phenology at 9,500 feet in Colorado.  But that's sub-alpine.

        If you want samples from the area around Crested Butte, CO, I or others at the Rocky Mtn. Biological Lab could do some sampling.

          Sam,

          Snowpack varies widely among years, so yes, your approach makes sense.

          Classic early season alpine and subalpine flowers are the pasqueflowers (refers to Passover and Easter, as they bloom about that time of year if not buried).  I have seen their blooms poking up through snow.  The eastern pasqueflower, Pulsatilla patens, occurs in the Rocky mountain chain.  The white pasqueflower, Pulsatilla occidentalis, replaces it further west in the Sierras and north.

            Sam and Cheryl,

            In my experience, conspicuous bee activity begins precisely when the
            earliest native willows start blooming. This can happen when there are
            still large patches of snow on the ground. In the mountains, it can be
            warm enough at midday for bee flight (ca. 55 deg. in the sun) even when
            night and average temps are still low. I've found Andrena and other bees
            in considerable abundance early in spring at high alpine passes where
            willow is in bloom, even though it still appeared "too early" for general
            flowering and bee activity at substantially lower elevations.

            Thus I recommend starting sampling on the first day with warm enough air
            temps for bee flight (ca. 55 deg?) within the blooming season of Salix at
            the elevation of interest (ask local botanists). Snow will likely still be
            present. If you wait until spring has fully arrived and there is general
            flowering you may miss Salix specialists, and in particular protandrous
            males of the earliest-emerging Andrena species.

            Good luck!

            John

              Sam-I agree with every thing that Jon just said. I will also say that fickle weather has really changed my concept of when bees will fly. This is especially true of Alpine locations - I have found bee activity around 5pm after a freak snow storm that same morning follow by a general warming trend up into the later afternoon. Only by happenstance did I have my net and was able to collect. I think that above 8000ft. all bets are off. If it is sunny and anywhere above 50 there will be something flying. Even at low temps but with sun bees can be found sunning themselves on rocks or just hanging out in flowers. With bowls, I would expect that as soon as there is snow free ground, it would be the time to start.

              On another subject - heavily forested locations have also caused me to re-evaluate what I think of as collectible areas[just sub-alpine]. I've worked in very heavily canopied lodgepole pine forests where the sunlight was dappled at best YET one tree coming down opened the way for a patch of sun follow by a few herbaceous plants [ I'm thinking specifically about Senecio in this case]. Not great collecting by any means of the imagination but after sitting for lunch I counted about 10 visitations in 50 minutes. I only collected two of the osmia [the only genera seen visiting] so there had to be at lest 3 different individuals...  really makes me rethink the flight distance for the bees visiting/trap-lining such isolated plants.

              Anyway - all the best,
              H

              Sam and Cheryl,

              In my experience, conspicuous bee activity begins precisely when the
              earliest native willows start blooming. This can happen when there are
              still large patches of snow on the ground. In the mountains, it can be
              warm enough at midday for bee flight (ca. 55 deg. in the sun) even when
              night and average temps are still low. I've found Andrena and other bees
              in considerable abundance early in spring at high alpine passes where
              willow is in bloom, even though it still appeared "too early" for general
              flowering and bee activity at substantially lower elevations.

              Thus I recommend starting sampling on the first day with warm enough air

                Salix is a good idea.  There is an alpine species, but it's inconspicuous.  Also widespread throughout the West ( http://plants.usda.gov/java/nameSearch?keywordquery=salix+nivalis&mode=sciname )

                It's pretty common to see Bombus queens on Salix shrubs at lower altitudes, maybe on the alpine species too.

                Sam and Cheryl,

                In my experience, conspicuous bee activity begins precisely when the
                earliest native willows start blooming. This can happen when there are
                still large patches of snow on the ground. In the mountains, it can be
                warm enough at midday for bee flight (ca. 55 deg. in the sun) even when
                night and average temps are still low. I've found Andrena and other bees
                in considerable abundance early in spring at high alpine passes where
                willow is in bloom, even though it still appeared "too early" for general
                flowering and bee activity at substantially lower elevations.

                Thus I recommend starting sampling on the first day with warm enough air
                temps for bee flight (ca. 55 deg?) within the blooming season of Salix at
                the elevation of interest (ask local botanists). Snow will likely still be
                present. If you wait until spring has fully arrived and there is general
                flowering you may miss Salix specialists, and in particular protandrous
                males of the earliest-emerging Andrena species.

                Good luck!

                John
