Towards a Semiautonomous Young Spruce Forest Late Cleaning

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Cleaning a seedling spruce stand is an important silvicultural task required to help the young spruce trees thrive. It is usually manual work with a clearing saw. Mechanized solutions have been proposed, but they have not worked out well, since the driver has challenges in seeing the seedling trees that should be left growing.

A Process Based Modeling Approach to Assess Temperature Impacts of Riparian Vegetation Management in a Southwestern Wisconsin Trout Stream

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Rising water temperatures driven by climate change threaten culturally and economically important salmonid fisheries throughout the Upper Midwest. Unsuitable thermal regimes degrade the effectiveness of habitat restoration projects in the region, thus strategies for mitigating peak summer stream temperatures are of interest to state and non ...

The Long‐Term Effects of Created Habitat on Native Salmonids in a Small Headwater Stream in the Boreal Forest

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Stream improvement projects are common across North America. The goal of these projects is usually increased fish production, but long‐term monitoring is rarely conducted to determine if these goals are met. We examined how a constructed pool‐riffle sequence influenced density and biomass of native salmonids (brook trout (Salvelinus fontinalis)

Woody cover and geology as regional‐scale determinants of semi‐arid savanna stability

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Savannas are vital for global biodiversity and carbon storage, yet their responses to climate change and human activity remain uncertain. Using remote sensing time series and Bayesian Linear Models, we show that drought resistance and resilience vary regionally, shaped by complex interactions between geology, woody cover, fire regimes, past climate ...
