Governance and infrastructure as pillars of performance: A socio‐ecological analysis of Ethiopian botanical gardens

PLANTS, PEOPLE, PLANET, EarlyView.
While botanical gardens are often perceived merely as recreational spaces for a weekend walk, in the Global South, they are true lifelines for nature and for the people who depend on it. Our research in Ethiopia explored what actually keeps these gardens running long‐term.

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration

Restoration Ecology, EarlyView.
There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...

The role of seed mix characteristics and soil amendments during post‐agricultural prairie restoration

Restoration Ecology, EarlyView.
Abstract Introduction Prairie restoration on degraded lands may be influenced by seed mix characteristics, including species richness and legume establishment. Soil amendments may facilitate restoration; however, the practical usefulness of techniques such as applications of whole soil and leaf mulch remains relatively unclear.

Effects of uncrewed aerial vehicle–applied triclopyr plus fluroxypyr rates on weeds and desirable forbs in Kansas tallgrass prairie

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract We studied the impacts of uncrewed aerial vehicle (UAV)‐applied triclopyr + fluroxypyr on rangeland weeds and other forbs in native tallgrass prairie. Two rates were tested: high (0.63 kg ae ha−1 triclopyr + 0.21 kg ae ha−1 fluroxypyr) and low (0.21 kg ae ha−1 triclopyr + 0.07 kg ae ha−1 fluroxypyr).
