Craig Luscombe, Manager – Seed Operations

Craig is a highly skilled seed collector with over 20 years of active experience working with the native flora of south west WA. Drawing from his experience, Craig consistently builds seed collections which are high in species diversity, and which always include those hard-to-find or difficult-to-get species often missed in purely commercially focused seed orders. Working in concert with Threshold Environmental projects from 2011 – 2013, Craig’s knowledge and expertise in native flora and seed collection techniques have substantially improved the quality of on-ground results in our projects.
