Shape of a remnant patch

• Shape tends to be important only for relatively small areas
  
  
• There seems to be a size beyond which shape does not matter
  
  
• For small remnants shape determines perimeter-core ratio
  
  
• Long thin remnants have more edge so are more open to edge effects
  
  
• Long thin remnants can lie on environmental gradients and contain more habitats than a square reserve
