The Chesapeake Bay watershed received an above average annual amount of precipitation in 2013. This accompanied degrading conditions in some regions of the Chesapeake Bay watershed and improving conditions in others.

Unsustainable fishing and aquaculture practices have put pressure on the Chilika Lake ecosystem. Dead fish thrown back into the water contaminate the lake while shrimp pens trap sediment and kill juvenile fish.
Chilika Lake Fishing and Aquaculture Pressures
During monsoon season excess sediment is deposited in Chilika Lake, mostly from Mahanadi River tributaries, nearby settlements, and agricultural lands. As the Lake becomes more shallow and its sea outlets fill in with sediment, increased flooding occurs.
Chilika Lake Sedimentation
Native to India, introduced to Hawaii Island in 1883 (via Jamaica, where it was also introduced), then introduced to Maui, Molokai, and Oahu; none were introduced on the island of Kauai. Mongoose were imported by the sugar industry to control rats in cane fields. This infamous mistake was made without much knowledge about mongoose. Mongoose, which are active during the day, did not control the rats because the rats are primarily active at night.

Improvements in water quality can be counteracted by changes in nutrient sources and land-use practices. Increased nutrient loads from stormwater and intensified agriculture often overwhelm the positive effects of best management practices.
Counteracting Factors Impacting Best Management…
Emergent wetland species are planted in a buoyant matrix that floats at the water surface. The roots of these plants grow through the matrix and take up the nutrients they need to grow directly from the water, potentially decreasing nutrient concentrations.
Floating Wetlands Structure and Impact
Gutters and downspouts installed onto buildings direct rainwater from roofs to rain gardens. Plants with deep root systems encourage stormwater infiltration and absorbs excess nutrient runoff.

This killdeer nest of nothing more than a shallow depression in the gravel, was found a busy marina parking lot. The owners of the marina placed cinder blocks around the well-camouflaged nest to prevent cars from running over the eggs. The killdeer mother was standing nearby when this photo was taken. This photo was taken in Easton, MD on May 22, 2014.

The Atlantic Bumper is a game fish found from Massachusetts to Florida in the Western Atlantic Ocean. They eat smaller fish, cephalopods, and zooplankton.
Chloroscombrus chrysurus (Atlantic Bumper)
The lined seahorse lives in the Atlantic Ocean as far north as Canada and as far south as the Caribbean, Mexico, and Venezuela. It swims in an erect position and uses its dorsal and pectoral fins for guidance while swimming. Lined seahorses feed mainly on minute crustaceans and brine shrimp, which they suck in through their snout.

Snowfall and the tilt of this bird feeder full of sunflower seeds did not deter these birds. Northern cardinals (Cardinalis cardinalis) and dark-eyed junkos (Junco hyemalis) were the primary visitors. The male cardinal is bright red and the female is a soft green-gray with red accents. Both have red beaks. The male junco found on the US East Coast has a pinkish beak and is slate gray on the top half of the body and soft white on the lower half. This photo was taken in February 2014 in Cambridge, MD USA.
