Forest defoliator outbreaks alter nutrient cycling in northern waters

Forest defoliator outbreaks alter nutrient cycling in northern waters

Abstract

Insect defoliators alter biogeochemical cycles from land into receiving waters by consuming terrestrial biomass and releasing biolabile frass. Here, we related insect outbreaks to water chemistry across 12 boreal lake catchments over 32-years. We report, on average, 27% lower dissolved organic carbon (DOC) and 112% higher dissolved inorganic nitrogen (DIN) concentrations in lake waters when defoliators covered entire catchments and reduced leaf area. DOC reductions reached 32% when deciduous … [more…]

What logging does to your water

What logging does to your water

There are a lot of issues with deforestation. However, for some nations around the world, logging jobs provide stable sources of income that might otherwise be unavailable. But now new research is taking a deeper look into the consequences of logging and asking, at what cost?





The recent study, which was published in Environmental Research Letters, comes from collaborating researchers at The University of Queensland (UQ) and the Wildlife … [more…]

The UN’s annual World Water Development Report 2018 has highlighted the need to use nature to combat the challenges of a growing population and climate change. In its detailed analysis, the report demonstrates that demand for water is increasing in developing countries, while simultaneously access is being put at risk by human development and climate change.

Deforestation, intense farming methods and urbanisation are putting these resources … [more…]

3 Surprising Ways Water Depends on Healthy Forests

educational infographic: healthy forests and biofiltration support better, cheaper water quality

Healthy forests are critical to providing clean water. Forests can positively impact the quantity, quality and filtration costs associated with a city’s water, sometimes even reducing the need for costly concrete and steel infrastructure.

The world’s major watersheds lost 6 percent of their tree cover on average from 2000-2014. Today, about 31 percent of the world’s watershed area is covered by forests. Deforestation in these watersheds, often caused by commodity … [more…]
