3 Project Introduction The importance of this project is to begin the location, education and identification process of Bryophytes and Liverworts in the NWACC Nature Area Living Laboratory.

4 Project Overview Educate on what a Bryophyte and Liverwort is Locate samples in the NWACC Living Laboratory Map the specimen with GIS/Google Earth Taxonomy

5 Project Goals Our goals with this project is to learn more about the taxonomy and ecology of mosses and liverworts through research in the field as well as documentation. We would like to see future students build on what we have started through continued research and identification.

6 Technology Used Leica ICC50 HD Microscope Garmin Handheld GPS unit Google Mapping Digital Camera Dissecting Scope Computer Software Word, Excel, Power point & Las EZ software for taking micro slide pictures.

7 Educate What a Bryophyte is NOT! Spanish moss produces flowers and seeds Reindeer moss lichen lacking leafy structure and color Irish moss purplish seaweed known as carrageen What a Bryophyte IS! Pioneering plant Non vascular plants Small herbaceous plants Photosynthetic phase life cycle is the haploid, gametophyte generation. Slow growth period Grow closely packed together Mats closely together

8 Educate What a liverwort is: Two distinct forms: Leafy Similar to mosses Easly distingused from mosses by their leaf arrangements. 2 3 rows while leaves in moss are spirally arranged. Thalloid Do not have leaves, instead the main body is flat. Easiest to identify. Some Liverworts produce asexually.

9 Uses of Mosses: Educate Bio indicators of air pollution Good indicators of acid rains to an ecosystem Erosion Control agents Moisture control Stability to soil Provides Nitrogen fixation in Sub Artic and Artic ecosystems Aesthetic purposes

10 Educate Structures of Bryophytes

11 Educate Structure of Liverworts

12 Field Taxonomy & Collection Methods What you need to be successful collecting mosses in the field Collect in individual paper bags or envelops DO NOT use plastic bags GPS Device for coordinates A good tool, Knife or chisel A hand lens (Loupes) Permission of the owner of the land and or collection permit Record Data with permanent marker Data to collect: Location, Date, Month, GPS Coordinates, Elevation, Habitat & Sample number

13 Field Taxonomy & Collection Methods What you will need in the Lab post field survey Dissecting microscope Microscope Slides Tweezers/scalpel/water for making slides Permanent marker to mark the slides NOTE: When preparing the slide use a dissecting scope to separate one leaf from your specimen, use water to aid in the slide making process. Access to a refrigerator to keep the samples from drying out

14 Educate Where to Look: Under trees Fallen logs Rocks Moist areas On tree barks Hot springs Prairies to Woodland areas Low light/shaded areas Become dormant in the summer time

15 Field Taxonomy & Collection Methods: We found several species' behind the Ropes Course. On the ground and on trees.

16 Field Taxonomy & Collection Methods: Behind the Ropes Course we found some fallen trees that have several species living together

17 Field Taxonomy & Collection Methods: We found several species' in the Post Oak Savannah

18 Field Taxonomy & Collection Methods: We found several species' on the side of the gravel pathway and in the area near the pond.

19 Photo samples taken in the field:
