When Pests Infest – A new tool for identifying at-risk forests

Forests globally are facing threats from insect and pathogen outbreaks. In this battle, drought and unsustainable logging have weakened forests, making them more vulnerable to attacks by insects and pathogens. Luckily, scientists joined the fight and have developed a tool to help identify forests that are at risk. Still, the world’s forests are not out of the woods yet.

Is the Bark Stronger Than the Bite? The Use of Models to Predict Bark Beetle-Induced Tree Mortality

Bark beetles can cause widespread tree mortality by disrupting the flow of water and nutrients. These trees are critical in sequestering carbon from greenhouse gas emissions. By accounting for beetle phenology as well as tree physiology, modeling can help predict bark-beetle induced tree mortality that can result from climate change.

Dead and Gone? – The loss of decaying wood communities in urban forests

Forests are beautiful. From flourishing plants to tranquil wildlife to decaying logs, all parts are beautiful, vital, and connected. Dead logs are responsible for maintaining a healthy forest thanks to teams of fungi and wood-dependent insects inside. These organisms break down plant material to add nutrients back to the ecosystem. Forests are essential for human health and well-being, but human disturbance could threaten these ecosystems. To keep our forests healthy and beautiful, we depend on these decomposers, but can they rely on us?

Indigenous Fire Practices Work

“Fire exclusion policies forced California Indian communities and forest managers to curtail their routine cultural and prescribed burning practices. Despite these policies, Karuk and Yurok basketweavers retained their knowledge, maintained their practices and, most importantly, developed several innovative techniques to replicate fire’s effects on hazelnut to produce essential basketry materials.” (Marks-Block 2019)

Friend or foe? Invasive earthworms can benefit agriculture but harm forests

Earthworms are welcome guests in the garden, but it’s a different story in the forest. By consuming and removing leaf litter too fast they set in motion complex cascades of ecological changes, with long-term negative effects on soil fertility and biodiversity.
