Drosera patens

Drosera patens is a small carnivorous herb in the sundew family, distinguished by rosettes of glandular, mucilage-tipped leaves used to trap and digest small invertebrates. This adaptation allows it to supplement nutrient uptake in soils typically deficient in nitrogen and phosphorus, a common feature of the nutrient-poor habitats sundews occupy. As with other Drosera species, it likely relies on insect prey captured via sticky glandular trichomes, with digestion aided by enzyme secretion, and reproduces through seed production following pollination, though specific behavioural and life-history details for this species remain poorly documented in the scientific literature.

The species is endemic to Australia, where its distribution is tied to specific soil and moisture regimes typical of sundew habitat, though detailed habitat classification has not yet been formally assessed. Populations are likely restricted to localized wetland-associated or seasonally moist substrates characteristic of the genus.

The species is classified as Endangered, with a decreasing population trend. Key threats include agricultural expansion and land clearing, urban and residential development, altered fire regimes and inappropriate burning, groundwater extraction and associated hydrological disruption, and climate change leading to reduced precipitation. These pressures collectively degrade or eliminate the specialized moist, nutrient-poor microhabitats the species depends upon.

Conservation measures specific to this species are not well documented publicly, though its Endangered listing under IUCN criteria indicates it is subject to ongoing monitoring and assessment as part of broader efforts to track Australian flora at risk from habitat loss and hydrological change.

Given the multiplicity of ongoing, unmitigated threats, particularly habitat clearing and water table alteration, the species' trajectory remains one of continued decline unless targeted habitat protection and hydrological safeguards are implemented.

Drosera patens inhabits seasonal wetlands, clay-based swamps, and winter-wet depressions in the jarrah and wandoo woodlands of southwestern Western Australia. The species requires specific hydrological conditions, growing in areas that flood during winter months but dry out completely during summer.
