Preserving Habitats That Safeguard Shores
This goal measures the condition and extent of habitats that protect the coasts against storm waves and flooding.
Storm protection by coastal habitats is worth billions of dollars each year.
What Does This Score Mean?
The reference point for Coastal Protection compares the current extent and condition of five key habitats that protect coastlines (mangrove forests, seagrass meadows, salt marshes, tropical coral reefs, and sea ice) from flooding and erosion relative to their condition in the early 1980's.
A score of 100 would indicate that these habitats are all still intact or have been restored to the condition they were in during the early 1980’s. Any score below 100 indicates that these habitats have declined in coverage or in health since then, with lower scores indicating more significant declines.
The current score indicates that although, in many places, these habitats remain healthy and intact, the extents of all five habitats have been substantially reduced or degraded when compared to the early 1980s reference years.

How Is It Measured?
Each goal is evaluated on the basis of four dimensions
Present Status is a goal's current value (based on the most recent available data) compared to a reference point.
Trend is the average percent change in the present status for the most recent 5 years of data.
Pressures are the sum of the ecological and social pressures that negatively affect scores for a goal.
Resilience is the sum of the ecological factors and social initiatives (policies, laws, etc) that can positively affect scores for a goal by reducing or eliminating pressures.
Pressures are human-caused stressors that influence both ecological and social systems, negatively affecting the ability of a goal to deliver its benefits to people.
Status refers to the current value of a goal relative to its goal-specific reference point. The reference point is the best condition for a goal that can reasonably be achieved; it is a target to aim for when taking actions to improve ocean health.
