Moisture and Species Effect on Water Colour Generation in an Australian Temperate Forested Catchment
ABSTRACT South‐eastern Australian forested catchments supply most of Melbourne's drinking water, and discoloured water poses significant challenges for authorities because of the need for complex and costly treatment procedures. Identifying the sources and mechanisms of colour production is therefore critical.

Riparian zones in the United Kingdom are diverse but prone to anthropogenic changes and invasive species like impatiens glandulifera. This study introduces a method to identify and map these flowers using a computer vision framework and UAV imagery, wrapped into an executable program called the semi‐automatic thresholding tool (SATT). Validation showed

Restoration thinning promotes resprouting and recruitment in an Australian floodplain forest
Thickening of woody vegetation has degraded numerous ecosystems globally. In forests, woody thickening often follows gap‐creating disturbance that removes mature trees and promotes the dense recruitment of woody resprouts or seedlings. Restoration thinning seeks to reduce tree densities in thickened forests to hasten recovery of stand structure for ...

Automation of pollen analysis using a computer microscope : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University [PDF]
The classification and counting of pollen is an important tool in the understanding of processes in agriculture, forestry, medicine and ecology. Current pollen analysis methods are manual, require expert operators, and are time consuming.
