| The above pool has quite a tadpole count for its size. The pool is rapidly shrinking. Low seasonal rainfall has effected the local water tables. These pools are breeding habitat for redlegs, chorus frogs, and boreal toads. The pictures on the right depict the outcome of this unsuccessful race against time. Some of the pools dry up before the larvae even start to grow legs. |
| Tadpole predator: Predacious Diving Beetle Larva |
| Complete dessication: Some of the bottoms looked like this "Last Stand"; others were picked completely clean by shorebirds. |
