Garden ponds support amphibians, invertebrates and birds. Their design, management and chemical inputs affect the welfare of resident and visiting wildlife throughout the year.
Garden pond welfare encompasses both the amphibians and invertebrates that depend on ponds for breeding and overwintering, and the visiting birds and mammals that use ponds for drinking and bathing. Individual frog or toad welfare includes the risk of desiccation during drought (particularly relevant during road crossings to ponds), predation by domestic cats (a significant mortality risk for breeding frogs), and mortality from freezing in shallow ponds in severe winters. Pond design and chemical management choices directly affect whether the pond supports welfare-positive wildlife habitat or becomes a trap for animals that cannot safely exit or are exposed to toxic inputs.
