Field Notes

It was raining, so it was difficult to get good photos without damaging the camera, but I think I got them all.... I had to come back the next day to take some better shots. I'm not sure how to record species diversity when I am "just looking around." Is it the number of species within 5 meters? 50 meters? within eyesight?

The leaves are large and oval shaped with smooth edges.

The flowers were growing in finger-like bunches.

The stems had swollen joints and grew in a zigzag pattern.

nice spot

A beautiful place--too bad you found knotweed there! :)

Cloudy skies

Fieldwork on the rainiest day of this otherwise super dry summer?! That's some serious commitment!

Thanks for the glimpse of beautiful Vinalhaven in your site photo!

yes, and good question

Hi there,

I have confirmed your identification - you made a very clear case and reported on relevant characteristics. Well done.

You ask a great question about biodiversity counts and the "just looking around" method. The truth is, a biodiversity count is only useful when you have defined the area in which you are looking. If you don't have a defined area, like a quadrat, a biodiversity count is meaningless data. Your question hit the nail on the head.

cheers.

Knotweed

Good job trythis. I made sure the pictures we took were better than those at Ft. Williams. Hope you or myself win the camera.
