Tuesday evening talk on April 17, 2012 at 7:00 pm in Rom 328 of the NAU Biology Building
Mike Kearsley, Vegetation Mapping Coordinator for Grand Canyon National Park, has sampled and mapped over 200 plant communities across 1.4 million acres of diverse habitats from Lake Mead to the Kaibab Plateau since 2007. Mike will talk about the many significant range extensions and relocated species that his team has found for Grand Canyon and Arizona during their surveys over the past fifteen years.
Saturday morning field trip April 21, 2012.
Plant Walk at Homoloni State Park, Winslow, Susan Holiday, the volunteer botanist who is completing a floristic inventory of the park for Arizona State Parks, will be leading the walk. We will be looking at plants of the Navajoan Desert and nearby Little Colorado River. We will also be able to view the ruins and a graveyard dating from the early 1900's on site. A checklist will be available. Meet at the Arizona State Credit Union parking lot, southwest corner of Butler and Beaver at 8:30 am. Be prepared for all kinds of weather. It could be cold, windy, hot, etc. The weather at Homolovi is as fickle as the weather in Flagstaff. Come prepared with sun protection, water, food, and car or gas money for carpooling. The walk will be over at about 1:00 pm. There is a $7.00 charge per car.
Tentative June or July Moss Workshop: Theresa may do a 1 day workshop (9AM - 5pm) in June or July and the final date will be announced in the beginning of April. She will provide fresh specimens, but would encourage folks that went to the moss walk to bring along their specimens. The goal of the workshop would be to familiarize folks with the microscopic (and necessary) identification of the 10 most common bryophytes in the area, 5 associated with dry habitats and 5 preferring mesic/semi-aquatic habitat. She'll review morphological terminology as necessary for each species and highlight their ecology, which can help differentiate closely related or similar appearing taxa. Handouts will be provided including keys, some of which are available online through the Flora of North America Volumes 27 & 28. If you own fine tweezers, please bring them along! Many moss leaves are only 1 mm long! (Theresa Clark recently graduated with her Master's in biology at NAU. Her thesis focused on the flora and ecology of bryophytes (mosses and liverworts) in Grand Canyon National Park.)
