We Are Group Vernal!

Welcome, welcome, welcome.

Group Vernal is Yvonna, Tessa, Mary, and Rick...



And these are our babies:


LAVERNE
AND
SHIRLEY
Our ultimate questions are: How do you define a vernal pool? How are these ecosystems ecologically important?

What is a vernal pool and are we actually studying a vernal pool?

Vernal pool-Vernal pools, also called ephemeral pools, are temporary pools of water. They are devoid of fish, and thus allow the safe development of natal amphibian and insect species.

Day one out on the Tamposi we looked for the signs that what we were studying was in fact a vernal pool. First, we found that the area was isolated with no water source flowing in or out of the pool. Two, there were no populations of fish present in the remaining water of the pool. And three, the species that were present, such as green frogs, helped us determine this was what we were hoping for!

This pool is interesting because most vernal pools are dried up by this time of year. We are very lucky to have any water! Laverne and Shirley are the two areas where water remains but literally a week earlier they were connected. She is draining fast!

Stay tuned for more...

Your introductory page certainly captures our attention! I also appreciate your link to the veranl pool website.
