Reactive and inconsistent practices hamstring efforts to manage invasive plants in the US

"...AMHERST, Mass. - As summer unfolds, more than 500 species of invasive plants will be taking root in fields, lawns, and gardens across the US. As plants continue to move north driven by climate change, the number of invasives will only increase..."

FOREST INK: Long-term, positive results using an organic approach

"...Their findings were described as follows: “We found that a single (one-time) application of compost doubled forage production (increasing 40 to 70 per cent) and soil C sequestration (on average one ton/hectare) over three years on both coastal (wet) and Sierra Foothill (dry) Mediterranean grassland systems. Compost decomposition provides a slow-release fertilizer to the soils, leading to increases in carbon sequestration and plant production. Net ecosystem C storage increased by 25 to 70 per cent without including the direct addition of compost C, while compost had no effect on nitrous oxide N2O or CH4 emissions..."

Introducing the Biodiversity Conservation Collection EveryONE: The PLOS ONE blog

"...Three studies among the first batch of articles published in this Collection address the impacts of climate change on biodiversity and potential mitigation strategies. Carbon sequestration has been suggested as a potential approach to mitigating the effects of greenhouse gas emissions responsible for global warming. In Spain, Morant et al..."
