Darwin Harbour is globally significant as a tropical, macrotidal, monsoonal harbour that is generally in very good condition. There are major development proposals for Darwin Harbour, including significant plans for population growth, industrial expansion and resource processing infrastructure, and consequent increases in shipping and dredging. These developments pose risks for the natural, cultural, aesthetic and recreational values of the Harbour, which need to be managed.

The Mackay-Whitsundays-Isaac region is diverse, with rainforests, ranges, creeks and rivers, wetlands, beaches, islands and reefs which support high biodiversity. The region supports productive agriculture, particularly grazing and sugarcane, as well as expanding urban centres. The Mackay-Whitsundays-Isaac region is rapidly developing due to economic development, climate, livability and natural beauty. This region is expected to double in population within twenty five years.

Residents of the Chesapeake Bay watershed depend upon a healthy Bay for food, recreation, and commercial enterprises. But the ways in which we use the watershed’s lands—from driving our cars to spreading fertilizers—impact the health of the Bay’s waters. Wastewater treatment plants, agricultural operations, and urban runoff are major sources of the nitrogen, phosphorus, and sediment pollution that threaten the Bay’s health.

Moreton Bay is internationally recognised for its large population of green sea turtles and dugongs, and for its unique location next to a major capital city. Following the January flood, there has been serious concern about the impact of the flood plume on these symbolic Moreton Bay creatures. This newsletter provides an overview of some of the initial flood impact assessment results for seagrasses, turtles and dugongs, and identifies the risks that need to be monitored.

This newsletter summarizes the baseline health assessment produced in 2011 by EcoCheck for Friends of Deep Creek Lake in preparation for production of future annual lake report cards. A unique assessment framework and preliminary data analysis results are presented, along with suggestions for future work and action items for concerned citizens. For further details, see the full assessment document.

Intense rainfall between 10-12 January 2011 caused flash and river flooding throughout the region. This newsletter focuses on the flood impacts on creeks, streambanks and paddocks. The floods caused significant impacts to waterways and the adjacent floodplains. The greatest impacts occurred in the Lockyer, Mid and Upper Brisbane and Bremer catchments with devastating loss of life and significant environmental damage.

The 2011 floods in South East Queensland were devastating to the people and economy of Queensland, with lives lost and homes and infrastructure destroyed. As communities across Queensland rebuild their homes and businesses, the impact of the floods on the ecosystems that support commercial and recreational activities of the state are unknown.

Blue crabs are one of the best-known and most celebrated symbols of the Chesapeake. Their populations in the Bay have hovered near historic lows for much of the last decade, but have recently begun to show signs of improvement. This newsletter reviews the current status of the blue crab population in the Chesapeake Bay as well as the management systems in place to monitor and protect this iconic species.

Human cultures are defined by the biological and physical environments in which they live. This newsletter examines—through case studies in Belize, Brazil, Fiji and Panama—the marine managed areas developed for the sustainable use of these environments and resources.

Encouraging local marine resource users to adopt sustainable practices that conserve biodiversity and habitat is the challenge faced by all marine managed areas worldwide. Using three different approaches to motivating behavior changes, 27 case studies were selected for review. This newsletter focuses on the design and success of those approaches as they were employed in three locations: Morro Bay, California; Laguna San Ignacio, Mexico; and Kubulau, Fiji.
