P S LAKE, 2007 Flashcards
What is needed to re establish river populations
Knowledge of the species, habitat, dispersal
How might organisms survive disturbance
Refugia
What is river connectivity
The joining of river habitats between unatural features
What is lacking from most river restoration projects
Knowledge of ecological theory
What size are most river restoration projects
Small scale
What negative occurs after a project is fi finished
It’s not monitored or kept
What can river restoration projects help to test
Ecological theories like population dynamics and community
Why must stream connectivity be up kept to restore rivers
Fish like the galaxiid move up and down the stream so longitudinal conservation is important
What wre natural streams subject to
Hydrological events droughts floods
What can a drought be described as
A ramp, disturbances increase
What disturbances are refugia required for
Flood drought hot cold predation
What are the negatives of channelisation
Increases flood severity and reduces refugia
