Aquarium
gravel represents substrate. The salmon eggs are small glass
beads. Bird seed is used for top gravel to cover the redd. The
top gravel rinses off showing turbulent destruction of redd
from high water flow. (The salmon pictured here are mini-rainbow
trout taken from small fishing lures. Let me know if you have
any other resource for mini-salmon!)
Trees
standing in clay for creation of forests and riparian areas
on model. The felt and felt strips are used to represent ground
cover.
The
root wad is made using small sticks stuck into a wad of clay.
Large
woody debris is made using small sticks and vegetation broken
or torn into appropriate sizes.
