Aquatic Macroinvertebrate Feeding Mechanisms
A comparative study was done by a tenth grade Telluride High School student, in which stream insects were collected at two distinct locations, Bridal Veil Creek and the San Miguel River in Telluride. The study hypothesized that more insects using the “scraping” method of feeding, in which algae is scraped off rocks and ingested, would be found at the lower site in town due to lower water velocity, direct sunlight, increased nutrients and algal growth.

Bark Beetle Distribution and Forest Density
An eleventh grade Telluride High School student studied the effects and distribution of bark beetle in the forested areas of Bridal Veil Basin.  Coniferous tree species in the Telluride region are susceptible to a naturally occurring root disease, as well as effects of long-term drought, making them an easy target for some bark-beetle species.  The objective of this study was to determine if differences in forest density affect bark beetle infestation rates.

Aquatic Macroinvertebrate Distribution and Mine Drainage
Stream insects and water quality samples were collected by a tenth grade student in two headwaters locations within the San Miguel River Watershed.  Bridal Veil Creek was hypothesized to have a higher biodiversity index due to good stream health, as opposed to Howard’s Fork, which has several draining mine adit tributaries, tailings piles and highly mineralized surrounding topography.
