Dorset Wildlife Trust has brought two Mangalitsa-cross pigs to Brownsea Island as part of an ecological management initiative. The animals, loaned from the Salt Pig farm at Putlake, are intended to assist in controlling bracken growth that has become dominant in certain areas of the island’s habitat.

The pigs, currently four months old, are expected to grow to approximately 180 kilograms as adults. They represent a breed related to the hairy Hungarian Mangalitsa, a stock developed during the 1830s through crossbreeding eastern European domestic varieties with wild boar. The pair have been placed in an enclosure on the northwestern portion of the island.

According to DWT representatives, the pigs will naturally help restore ecological balance by turning over soil and disturbing rhizomes and roots while foraging. This activity is expected to reduce bracken coverage and create space for increased plant and wildlife diversity. While bracken is acknowledged as a native plant with ecological value, its unchecked expansion has disrupted the woodland understory balance in some locations.

The trust reports that the animals are acclimating well to their new environment and are displaying characteristic inquisitive and playful behavior. The wildlife trust manages 100 hectares of land on the northern side of Brownsea Island in collaboration with the National Trust. The island is designated as part of the Purbeck National Nature Reserve and holds international significance for wildlife conservation.
