What you’ll learn

  1. A wetland is many habitats at onceExplain how salinity, tides, edges, and habitat variety create many niches in one coastal wetland.A wetland is a shifting mosaic whose biodiversity depends on varied patches and changing access.
  2. Food starts with wetland plantsTrace energy from plants and detritus through roots, mudflats, and connected food webs.Plants build food and structure, while detritus and living surfaces feed consumers.
  3. Nursery habitat protects young animalsDescribe how shallow, structured, and connected habitats help young fish and shellfish survive.Nursery function depends on shelter, food, water quality, and routes among habitats.
  4. Mobile species connect the coastlineExplain how birds, fish, crabs, tides, and rivers connect wetland habitats across seasons.Movement links places and life stages, but connectivity can also carry pollution and stress.
  5. Resilience depends on variety and careUse biodiversity monitoring and restoration principles to evaluate a connected coastal-wetland network.Resilience is measured through habitat, food, movement, life stages, and recovery.

Questions this course answers

Why is a coastal wetland a mosaic?

Different patches support different organisms while water connects them.

Put a biodiversity survey in order.

A useful survey maps, chooses, samples, then interprets.

What is detritus?

Microbes and small animals process dead leaves and stems.

Match each feature to its role.

Each feature supplies a different food-web service.

What makes nursery habitat useful?

Nursery function is about survival and growth during a life stage.

Put a nursery assessment in order.

The assessment follows an animal’s needs and route before testing results.
