Is in Milford. Oyster River is on the town line Milford/West Haven.
There is a picture of the cove of the mouth of the Oyster River in his
1920 Vegetation of Depositing shorelines by George Nichols - one of
CT's best ever Plant Ecologists. What today is unusual about this
photograph is that the Cove was dominated by eelgrass. I compiled all
available historic data about the distribution of eelgrass (it grew
throughout LIS) but by the late 1980's - was no longer found east of
Clinton. I presented these findings to the former Living Resources
Workgroup (now defunct) of the Long Island Sound Study and suggested
that this decline was likely due to nitrogen enrichment. I then knew
what those sailors felt like when they suggested the world was not
flat. Manh of you have heard about the eelgrass blight of 1931 -
which did cause a decline in eelgrass but beds had recovered fully in
eastern LIS by the mid-1940's. Recovery was poor or non-existent in
central and western LIS - suggesting a water quality problem in the
Sound. A few of you may remember the wildlife biologist Phil Barske -
Phil helped to plant 4 eelgrass beds in 1947 with donor plants from
the Niantic River. Only one of those survived in front of the house
of CT state wildlife biologist Beckley! This bed was last seen in the
early 1980's. Today we know that climate change has caused an
increase in the amount and frequency of African dust events - these
make landfall in the Caribbean in the summer and New England in the
spring. This dust carries pathogens that cause crop mortality in the
caribbean, asthma, reputedly sea fan dieoff in the caribbean. The
famous black blizzards began in 1931 - could the source of eelgrass
wasting disease - a slime mold - be the US mid-west? The chief group
concerned about eelgrass declines of the 30's were wildlife biologists
for then Brant fed almost exclusively on eelgrass. The brant adapted!
