Abstract:

Further biological diversity monitoring activities for the 1999 field season include two HabitatNet field courses. As of this report, one of the two field courses has been completed (Janaury 14 - 19,1999). The January field course participants were from Souhegan High School (Amherst, NH) and the July 10-17, 1999 field course participants includes teachers, college students (Souhegan High School graduates), and a videographer who also attended the Janaury, 1999 field course.

As of this report, thirteen (13) of the twenty-five (25) quadrats are completed within the hectare biodiversity plot (known as EEF1). Three additional quadrats (quadrats 13,19,25) are nearing completion.

Reference Note:

Past HabitatNet Field Reports (Numbers 1,2,3,4) describe the habitat types, protocols used in this biodiversity monitoring project, quadrat data, and species accounts. Copies of all reports are on file at the El Eden Ecological Reserve (Quintana Roo,MX), the Smithsonian Institute/ Man & Biosphere Program (Washington, D.C.), and with the Project Director at Souhegan High School (Amherst, NH).

Trip Reports:

14 - 19 Janauary,1999 SHS BioSwat Team

This was the first HabitatNet biodiversity program conducted during Janaury. Overall, El Eden Ecological Reserve was relatively wet and green with cool temperatures. Souhegan High School students ("BioSwat Team") conducted SI/MAB measurements in EEF1 during the five days. Quadrats 12 and 17 were surveyed and mapped (Appendix) and cumulative data on tree species in all thirteen (13) completed quadrats was calculated. Additionally, maximum / minimum temperature and humidity data were collected, as on previous trips, in Quadrat 1 (EEF1) at the "Jaguar Hut".

Concurrently, species observed, identified, and verified by the HabitatNet project director were noted and listed in this report. Additionally, several students conducted independent field projects with topics including: bat behavior, nature photography, and written habitat descriptions.

Trip Data:

Quadrat 12: 90%

Quadrat 17: 90% (evidence of wind thrown trees and early successional trees)

A total of 35 bird species were observed (checklist / field notes attached).

Concluding Remarks

"If the land mechanism as a whole is good, then every part of it is good, whether we understand it or not. If the biota, in the course of eons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering."

Aldo Leopold: A SAND COUNTY ALMANAC

Certainly, this report is just a beginning. Much more work needs to be done and will be done over the next several years. Basic taxonomic work complimented with continuing investigations of species interactions will allow us to more fully understand and appreciate the wisdom of Aldo Leopold.

Organismic adaptation and speciation can not keep pace with the accelerating extinction rate caused by our species ignorance. In addition to the basic research and investigations afforded by this project, a primary focus of HabitatNet is to reacquaint students and teachers with nature so that we may better understand our fundamental role and responsibility in safeguarding global biological diversity.

The short term goals for 1999 include:

(1) Continue quadrat tree surveys in the hectare biodiversity plot known as EEF1.

(2) Develop a botanical reference collection at El Eden (voucher specimens).

(3) Under the auspices of Marco Lazcano-Barrero, develop a voucher specimen collection of both invertebrate and vertebrates found within the biodiversity plot.

(4) Fall / Winter 1999: Begin intial interpretation of quadrat data compiled thus far.

Special Notes of Appreciation:

"HabitatNet" extends a special thank you to Marco Lazcano-Barrero (Director General; El Eden Ecological Reserve) and his staff for all of their ongoing effort and support of this project. ¡Muchas gracias!

This year we are most fortunate to have Ben Day, videographer, join our HabitatNet adventures! His talent and genius allow those who are geographically removed from El Eden Ecological Reserve an opportunity to experience it visually.

It was my great pleasure to have my colleague and friend, Susie Carlisle, co-lead the Janaury "BioSwatters". Thank you Susie for all of your efforts and literary moments!

Finally, it would be impossible to conduct these rapid biological assessment projects without the intrepid researchers from Souhegan High School. Their humor, intelligence, and spirit for adventure gets the job done! Thank you!
