Abstract

Remote detection is an efficient mechanism for understanding weed distribution and is critical for weed management, however current systems are expensive, technically-challenging and often inaccessible for land managers. This presentation summarises results from a 3-year project: Weed managers guide to Remote Detection: Understanding opportunities and limitations of multi-resolution and multi-modal technologies for remote detection of weeds in heterogeneous landscapes”. This collaborative project used ‘model’ weed systems (hawkweed, African lovegrass and bitou bush) to test the limitations of high-resolution RGB, multispectral and hyperspectral technologies across various airborne platforms (drone, satellite) using artificial intelligence (including classical machine learning and deep learning) to detect and map weeds in conservation landscapes, with the goal of determining feasible approaches for managers. Guidelines were developed, based on project learnings, that detail the opportunities and limitations of remote weed detection, prediction maps of weed distribution and provide decision support to enable land managers to target investment and optimise use of available technologies. We present an overview of the Guidelines and introduce the recently formed Weed Remote Sensing Community of Practice (WRS CoP) that links researchers to end-users and facilitates collaborations in this rapidly changing field. We present research learnings and outcomes from the project to contribute to improved options for remote weed detection.

OtherInvasive Species Queensland (formerly the Weed Society of Queensland) is excited to collaborate with the Council of Australasian Weed Societies (CAWS) in hosting the 23rd Australasian Weeds Conference (AWC). Join us from August 25 to 29, 2024 at the Brisbane Convention and Exhibition Centre for this significant national event.

Weeds continue to impact biodiversity, agriculture, and public spaces, posing challenges to productivity and land use. The 23rd AWC provides a platform to unite, share ideas, and explore effective weed management strategies. We extend a warm invitation to all involved in weed research, policy and extension to join us and contribute to this vital discussion.
