Grasslands restoration is working in the soil, too

USDA Invasive Species News -

A new study finds that tallgrass prairie restoration at a large Illinois preserve is working at a foundational level -- in the soil. Bacteria in the soil are recolonizing and recovering on their own to resemble soil found in remnant prairies. The study shows that a carefully managed restoration can produce successes even beyond easily-recognized plant and animal biodiversity.

Damming and lost connectivity for fish in Northeastern ecosystems

USDA Invasive Species News -

Fish that migrate between freshwater and sea ecosystems play a multitude of ecological roles. In the centuries since Europeans first colonized the Americas, damming and other disruptions to river connectivity have greatly decreased the migration opportunities of these species. A new article outlines the effects of lost habitat and river connectivity for these crucial fish.

Bornean orangutans' canopy movements flag conservation targets

USDA Invasive Species News -

Bornean orangutans living in forests impacted by human commerce seek areas of denser canopy enclosure, taller trees, and sections with trees of uniform height, according to new research. These orangutans are critically endangered, and despite intense conservation efforts, their numbers continue to decline. Additional habitat management strategies that account for their presence in forests affected by logging and other human activity are needed to ensure the species' survival.

Invasive plant species can enhance coastal ecosystems

USDA Invasive Species News -

Invasive plant species like seaweed can provide vital ecosystem functions in coastal areas where native habitats such as salt marshes and oyster reefs have severely declined. A new study finds that invasive species could be used to offset the loss of native habitats that provide storm protection, food production and other benefits to billions of people.
