To provide pollinator nesting habitat, cut dead perennial stems in their first winter

open access: yesInsect Conservation and Diversity, Volume 19, Issue 4, Page 933-944, July 2026.

The Biology, Ecology, Distribution and Management of Two Globally Invasive Weeds: Calotropis procera (Calotrope) and Calotropis gigantea (Giant Calotrope)

open access: yesWeed Research, Volume 66, Issue 3, May/June 2026.
ABSTRACT Calotropis procera and C. gigantea are emerging as globally invasive plants that can significantly alter ecosystems in areas where they have escaped from attended cultivation. Without effective management, these species can form dense monospecific stands, resulting in severe economic, environmental and social impacts.

Landscape and local factors influence solitary bee nesting, but reported effects show little consistency across studies

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Collectively, these findings indicate that agri‐environment schemes aiming to support solitary bees should integrate the provision of nesting resources with proximity to floral resources. The heterogeneity among studies highlights the need for solitary bee conservation measures to be tailored to local conditions and to the local fauna.
