Tiger salamanders are only aquatic during their larval stage. After they turn into adults they are terrestrial only returning to water pools when they are ready to spawn. They do however like moist land areas which they will readily find hideouts in.

If tiger salamanders are native to your area then yes please do stock your pond area with them. Just keep in mind that this species generally prefers fish free waters. The introduction of fish to historically fish less ponds has wiped out certain populations of this species.

Perhaps you could turn your pond into an amphibian/reptile sanctuary. That generally means no fish. A pond full of aquatic turtles, frogs, salamanders is a wonderful thing. Also stick to amphibians and reptiles that are native to your area as they may escape into the wild.

In California introduced bullfrogs and mosquito fish over the past 100 years have wiped out some of our native amphibian species. So be very careful what you put out there.
