In Hampshire, frogspawn typically emerges from January onwards. The timing can vary based on local weather conditions and location, but by March, many ponds across the county are teeming with these gelatinous clusters. Hampshire & Isle of Wight Wildlife Trust has documented early sightings this month in the New Forest – ponds in the woods can provide slightly warmer conditions.

Frogs lay their eggs in still or slow-moving freshwater bodies, preferring shallow areas that warm up quickly. Each female can produce up to 4,000 eggs, which are deposited in large, jelly-like clumps known as frogspawn. These clumps are distinguishable from toad spawn, which appears in long strings. The jelly surrounding the eggs helps to keep them hydrated and provides some protection from predators. However, frogspawn is still vulnerable to being eaten by fish, birds, and even newts.

Within two to four weeks, the eggs develop into tadpoles. At first, these tiny, wriggling creatures rely on the remaining yolk inside their eggs for nutrition. Once they hatch, they feed on algae and decaying plant matter before gradually developing legs, lungs, and the ability to breathe air. This incredible transformation from tadpole to froglet takes around 12–16 weeks, depending on environmental conditions such as water temperature and food availability.

Recent studies may suggest that climate change is influencing the breeding patterns of amphibians. Warmer winters and unpredictable weather can lead to frogs spawning earlier in the year. Data indicates a trend towards earlier breeding, with observations of frogspawn in southern regions appearing early. This shift can pose challenges, as early spawnings may be vulnerable to subsequent cold snaps, potentially affecting tadpole survival rates. Additionally, mild winters may disrupt hibernation patterns, leading to increased stress on frog populations.

Hampshire & Isle of Wight Wildlife Trust is dedicated to preserving the county's rich biodiversity. Through habitat restoration and public engagement, the Trust works to ensure that all wildlife, including amphibian populations thrive. The Trust manages several nature reserves, such as Winnall Moors Nature Reserve in Winchester, which provide ideal breeding grounds for frogs.
