Recently,
we had a small group of children and adults visit one of our bogs. The leader later wrote to tell us what they
found. “Chorus frogs, amphipods, snails,
dragonfly and damselfly nymphs. Your
wetland is most certainly a "home pond" for long-toed
salamanders...there may be only one or two other home ponds for these delicate
amphibians in San Juan Co." (Russel Barsh- Lopez Island)
We have
known for years that we had some “rare” species on our lands, but it is always
good to have the experts tell us what they are and where they are to be found. In 2006 Jean Y. Kekes of Charlton,
NY found a rare (for North
America) species of at the water edge of our land. It is a rare arctic-boreal, maritime moss,
most often found in Europe, notably in Great Britain. It was only the second U.S. occurrence of Bryum marratii (Marrat's bryum moss or Baltic bryum).
I did a little research on some of the finds in the
bog.
Long-toed Salamander |
Although
the long-toed salamander is classified as a species of Least Concern by the
IUCN, many forms of land development threaten and negatively affect the
salamander's habitat.
When
threatened, the long-toed salamander will wave its tail and secrete an adhesive
white milky substance that is noxious and likely poisonous.
Two
life-history features of amphibians are often cited as a reason why amphibians
are good indicators of environmental health or 'canaries in the coal mine'.
Like all amphibians, the long-toed salamander has both an aquatic and
terrestrial life transition and semipermeable skin. Since they serve different
ecological functions in the water than they do in land, the loss of one
amphibian species is equivalent to the loss of two ecological species.The
second notion is that amphibians, such as long-toed salamanders, are more
susceptible to the absorption of pollutants because they naturally absorb water
and oxygen through their skin. The validity of this special sensitivity to
environmental pollutants, however, has been called into question. The problem
is more complex, because not all amphibians are equally susceptible to
environmental damage because there is such a diverse array of life histories
among species.
Also found
is the RED-LEGGED FROG a species of amphibian, whose range
is the coastal region stretching from southwest British Columbia to southern
Mendocino County in Northern California, and is protected in British Columbia,
Oregon and California. As a member of the genus Rana, this species is
considered a true frog, with characteristic smooth skin and a narrow waist.
This frog requires still waters for breeding, and is rarely found at any great
distance from its breeding ponds or marshes.
