Drawing on a 2025 presentation by ecologist David De Angelis and relevant ecological research from Victoria, Australia, this paper examines how habitat management aimed at revegetation and weed removal can conflict with the ecological requirements of threatened herpetofauna. Evidence from grasslands, wetlands, and riparian zones demonstrates that many species persist in degraded, weed-dominated environments because these landscapes retain critical structural features such as open ground, thermal refuges, and appropriate basking and shelter opportunities. Case studies involving the Growling Grass Frog, Southern Toadlet, Swamp Skink, Glossy Grass Skink, Tussock Skink, and Striped Legless Lizard illustrate how overshading, dense woody revegetation, and rapid weed removal can exacerbate habitat loss, increase disease risk, or eliminate key microhabitats. The paper argues for a shift from species-centric plant restoration towards a structure-first, evidence-based approach that emphasises site-specific surveys, gradual habitat transitions, and the maintenance of open, sun-exposed environments. By challenging native–exotic dichotomies and restoration dogma, this work highlights the need for adaptive, species-specific management strategies that prioritise the immediate survival of threatened fauna while enabling longer-term ecological recovery.
