ABSTRACT The idle crayfish ( Austropotamobius bihariensis Pârvulescu, 2019), endemic to Romania's Apuseni Mountains, urgently requires a specific conservation plan. Due its recent description, efforts have been limited, highlighting the need for immediate and practical recommendations ensure protection. Over 13 years, field observations were conducted evaluate population trends identify threats following IUCN standards. Additionally, geospatial assessments predictive modelling employed estimate both optimal habitat current size under three distinct scenarios. primary identified include poor forest management, extreme drought, anthropogenic development riverbed alterations, all contributing declines in abundance. most severe impacts arise when these pressures converge at single site, compounded by chronic, low‐virulence plague infection (A‐haplogroup). total is estimated 31,150 (± 449.9 SE) individuals, with 1,163,754 m 2 of suitable habitat, which only 37.9% lies within protected areas realistic scenario. Poor water quality was found significantly reduce modelled size. In light findings, we propose series targeted actions tailored each area highlight importance extending measures beyond their boundaries. recommend implementing ‘ark sites’ concept regions ecological conditions, stable populations genetic diversity, safeguard species through effective management.
