Predator/prey cards

• The Striped Bass represents a non-native fish.
• These fish appear on the predator/prey cards.
• Predator/prey cards describe a situation with
  consequences for crabs and salmon in the estuary
  depending on factors such as your size and
  location.

Estuary condition cards

• Estuary condition cards describe the tides and
  different factors that will impact life in the
  estuary.
• The habitats below the low tide line include
  only the open water channel and the eelgrass
  meadows.
• If youre crab or salmon occupies a square that
  has any of a particular kind of habitat in it,
  you may claim that habitat. For example, if you
  have any bright green eelgrass in your square,
  you are protected by the eelgrass.

Habitat and tide zones

• The estuary playing board is divided into three
  areas low, mid, and upper estuary which are
  divided by lines across the board.
• The low tide line is marked in black.
• The habitat zones cross over these areas.
• To claim a habitat, at least 50 of your square
  must be covered by this habitat.

• Open water (blue)
• Mudflats (brown)
• Salt marsh (dark green)
