A Quest for Snails at Home Reveals Much More

Melrose, OR–May 14, 2017. 1530-1700. We’ve had some rain over the past week. Not having looked much for snails or slugs at our property, I decided to go out looking to see what I could find, and I figured the rain we’ve had over the last week would help my quest. I primarily looked in the closed-canopy oak woodland west of our house. I did find two species of snail and one slug species (two specimens); all native species. Both of the snails were with or in the process of laying eggs.

Beaded Lancetooth (Ancotrema sportella)

A very green Pacific Treefrog revealed itself by hopping from its perch in the grass. They breed in my neighbor’s pond to the north.

On my way to the oak woods I began to look at grasses, which I haven’t studied for some time, and checked a couple sheets of metal roofing along my gravel road. A familiar, large (3-4 ft) Gopher Snake was present and gave me good photos and an impressive striking and hissing video (links in comments on that species; click photo below).

While on the search for gastropods, I incidentally found a new vertebrate species for our property (not easy to do these days): an Ensatina (salamander). It was in a pile of scrap wood near our treehouse.

Rain has many positive sides! More observations and photos from today can be seen here. Also, my eBird checklist for the outing is here.
